Door Buzzer
Installation in
Brooklyn Heights

Quick answer: door buzzer installation in Brooklyn Heights is quoted per job, in writing, after we see photos of the doorway and count the households behind it, because the price here depends less on the panel than on three local things: how many households share the street door, what the Landmarks Commission will accept on the doorway, and whether the old wire between the cellar and the floors still tests sound. The quote covers the door station, the stations or phone answering for each household, the electric release in the door frame, a battery-backed power supply, the cable route and the door work needed so the door closes and latches on its own, all installed and tested from the stoop to every floor. Send photos to (347) 934-8335 or on WhatsApp, and we usually reply within two hours during working hours.

• Brooklyn Heights is billed at our standard Brooklyn rates; there is no historic-district surcharge, though a station chosen to satisfy the Commission can change what equipment is ordered.
• All work is done under New York State license #12000287431, and equipment is ordered only after the written price is approved and the deposit is in.
• We work for whoever controls the door: an owner who lives in the house, a family that rents out the upper floors, a co-op or condo board, a managing agent, or a shop owner with the landlord's written approval.

Need Repair in Brooklyn Heights? When One Part Is the Fix and When a Doorway Needs a New System

Plenty of installation calls from the Heights begin as repair calls. A tenant on the fourth floor of a divided house cannot buzz anyone in, the board of a co-op hears that half the handsets crackle, or the owner of a single-family house notices the bell has gone silent. Some of these are genuine one-part repairs: a tired transformer in the cellar, a strike whose screws have pulled out of an old wooden frame, a handset with a broken cord, a bell button that has corroded behind its brass plate. We price those as repairs and say so.

The pattern changes when the faults spread. When several floors fail within months of each other, when the trouble comes and goes with the weather, or when the system is old enough that its parts are no longer made, the cause is usually the cable from the cellar to the floors or the system as a whole. A repair then lasts a season. The answer is to meter every pair, keep the ones that test sound, replace the ones that do not, and put one system with one power supply on the whole house. One complaint on Yelp about intercom work near the Heights described an electrician "disconnecting, dismantling and throwing out a perfectly working exterior intercom panel." We would rather test first and tell you honestly that the panel on your doorway is fine, if it is, than remove a working part from a landmarked front. If a repair is all your doorway needs, our Brooklyn door buzzer team will price it that way.

Door Buzzer Installation for Brooklyn Heights's Architecture

Six kinds of entrance make up nearly every buzzer request we get from the Heights. They differ in exactly the things that decide a buzzer job: how many households share the door, how many doors a visitor might try, what the walls and the doorway are made of, where the cellar is, and how much the Landmarks Commission will want to see before anything is fastened to the front.

Row houses kept as one home: hearing the stoop from the top floor

The simplest Heights job is also one of the most requested: a single family in a four- or five-story house, a bell button at the parlor door, and a bell or chime that only the people on the parlor floor can hear. The answer is a compact station at the door and indoor stations on the floors the family actually lives on, usually the kitchen floor, the parlor floor and the top bedroom floor, with phone answering added if they want to answer from upstairs without a station or from outside the house.

The work lives in the doorway and the cellar. The station has to sit where the Commission will accept it, which in practice means within the doorway, on plain surfaces, and as small as it can be while still having a camera and a speaker. The cable has to get from that station into the house through plain masonry rather than carved stone, which often means a short, careful hole behind the station itself, and then find its way down to the cellar and up to each floor inside the walls. In an old plaster house, that route is planned before anything is drilled, floor by floor, with the owner.

The release goes in the parlor door's frame. Many of these doors are original, tall and heavy, and many frames have been patched after old lock changes. A fail-secure electric strike needs solid wood around it and a door that drops its latch into the keeper every time, so the door is checked before the strike is chosen, and any frame repair is named on the quote.

Houses split into flats: one doorway, several households, one system

When a house was divided long ago, the doorway usually tells the story: a bell button for each apartment, some brass, some plastic, some added with a strip of tape for the label. Behind them, each button may have its own pair of wires running to its apartment, or several may share a cable that was spliced in the cellar decades ago. Before we promise anything, every pair is traced and metered from the cellar to each apartment, because the condition of those wires decides whether a new system can ride on them or needs new cable.

A divided house also has more people with an opinion. The owner may live on the parlor and garden floors and rent the floors above, or may live elsewhere and rely on a managing agent. Tenants may want a wall station, a phone app or both. A two-wire system can carry audio and video to each apartment over one pair and still let individual apartments add phone answering, which suits a house where the people upstairs range from students to long-time residents. We set out the options for the owner in one written quote, with each household's station listed so it is clear what everyone gets.

Prewar co-op lobbies: the board, the riser and the glass inner door

The co-op buildings on the main residential streets usually have the layout the city's rules were written around: a street door into a vestibule with mailboxes, a glass inner door into the lobby, and an elevator and stair beyond. The rule 1 RCNY §42-01 allows the street door into the vestibule not to self-lock when the inner door from the vestibule self-closes and self-locks, which often decides where the release goes and keeps the mailboxes reachable for the carrier. The Orange Street incident in 2024, when the inner door's glass was smashed, is a reminder that the inner door takes the abuse in such buildings, and its frame, glass and closer deserve attention alongside the electronics.

The riser is the other half. Many of these buildings already have a multi-pair cable running up a closet stack or the stair hall to every apartment. If its pairs meter sound, a new system can use them, which keeps cost and disruption down. Boards need to see that test result before they vote, along with a clear statement of what the building pays for, what each shareholder's apartment station involves, and whether any part of the system carries a monthly fee.

Converted carriage houses: finding the door on a back lane

City Lore's history of Grace Court Alley describes a one-block dead end off Hicks Street lined with mid-nineteenth-century carriage houses, two and three stories tall, built to serve the mansions on Joralemon and Remsen Streets, later turned into garages and then homes, most still with their hay cranes. Houses like these have their own buzzer problems. The old carriage opening is often now a large window or a garage door, the human door may be small and set to one side, and the walls are thick brick with no cellar under some of them.

The station goes where a visitor will look for it and where the Commission will accept it, which is usually beside the human door rather than across the old carriage opening. Power and cable come from inside the house by the shortest concealed route, and where there is no cellar, the power supply is mounted in a closet or utility space the owner can reach. If the garage door is used by the household every day, its own opener stays separate; the buzzer opens the door people walk through.

Late Federal houses in the north: wood doorways and very little wall

The oldest houses in the Heights, mostly in the northern blocks, are smaller and lower than the brownstones that followed. Their doorways tend to be wood rather than stone, with narrow casings and sometimes a fanlight above. There is often no plain masonry close to the door at all. That pushes the station toward the slimmest equipment we install, mounted on the casing or a plain board within the doorway, with its cable dropping straight through the floor behind it rather than across the front.

Converted and newer buildings: long runs and many apartments

The Hotel St. George complex, built in stages from 1885 to 1930 and once the city's largest hotel, has held co-ops since 1984 and student housing since the late 1990s. New York YIMBY reported in March 2026 that the former Jehovah's Witness headquarters at 25–30 Columbia Heights is planned as 661 rentals, with a 2029 completion target. Buildings of this kind need a directory or code panel, cable sized for long distances, and a clear split between which doors serve which residents. They are planned from drawings with the building's own team, and the doorway on a district building still follows the Commission's rules.

How the Landmarks Rules Shape a Buzzer on a Brooklyn Heights Doorway

Most of what makes a buzzer job in the Heights different from one a mile away comes down to a handful of sentences in the Landmarks Preservation Commission's documents. We read them closely because every station we mount on a district doorway has to live with them, and because owners who know them in advance make better choices about equipment.

What the Commission's documents actually say

The Commission's guidelines for restoring architectural features list "installing intercom boxes" under the work for which its approval is required. Its Permit Guidebook, Chapter 11, on health, safety and utility equipment, includes a section on installing light fixtures and intercom panels. That guidance says equipment of this kind cannot be on or in front of a primary facade unless no other option exists, that it should be put in discreet locations, that it should not be fastened through cast iron or decorative surfaces, and that conduit should be concealed through plain masonry, with only about ten inches left visible and only with staff approval. At a doorway, it allows light fixtures within or beside the door, up to two, plus one intercom panel. Chapter 8 of the guidebook, on yards and areaways, names Brooklyn Heights and points intercom installations back to Chapter 11.

The Commission's 2018 rules amendments addressed the same family of objects. They describe lighting, security cameras and intercom panels as objects common for security, and the proposed text would prohibit installing many of them on a primary facade unless there is no feasible alternative or the location is required by an agency or another entity. Where they are installed, the work has to minimize or avoid damage to significant architectural features, and the object has to be as small as possible.

What that means for the station we choose

For a typical Heights house with one entrance on the street, the parlor doorway is the only place a visitor can ring, which is exactly the situation the "no other option" language anticipates. The station then goes within the doorway, on the plainest surface available, at a size that does what the household needs and no more. A three-household house does not need a station sized for twenty; a family that wants video does not need a panel with a keypad they will never use. Choosing the smallest station that still has a readable label for each household, a speaker and, if wanted, a camera is both good design and the best preparation for a filing.

The single-panel pattern matters too. If a doorway already has a doorbell camera, an old bell plate and a newer button, they should be consolidated into one station rather than added to. Old plates that no longer work come off, and their holes are filled, when the new station goes up.

What that means for the cable

The cable is where careless jobs on district houses show. A run of surface conduit up the brownstone, or a cable stapled across the brick to a hole by the cellar window, is exactly what the guidance is trying to prevent. We plan the route so the cable leaves the back of the station and enters the house directly through plain masonry or the door frame, and then travels inside the house to the cellar and the floors. Where the station has to sit on wood, the cable usually drops straight through the floor of the vestibule or the frame behind it.

Who files, and when the work happens

The Commission's permits are issued to the owner of the building, and we prepare what an owner or their architect or expediter needs for the doorway: the station's dimensions and finish, photos showing where it goes, a description of how it is fastened and how the cable gets inside. Installation on the doorway happens after the approval the building needs is in hand. Interior work is a different matter; the Commission offers an expedited Certificate of No Effect for specific kinds of interior work in historic-district buildings, which it says can be issued within three days, and owners with interior Buildings Department filings should ask whether that path applies to them. None of this is legal advice for a particular building; the Commission's own staff are the final word on what a given doorway needs.

Which Brooklyn Heights Buildings Must Have a Buzzer, Who Keeps It Working and Who Approves the Doorway

• Eight or more apartments is the main threshold. Multiple Dwelling Law §50-a and 1 RCNY §42-01 require self-closing, self-locking entrance doors and an intercommunication system at the main entrance of class A multiple dwellings of eight or more apartments erected or converted after January 1, 1968.
• Most Heights buildings are older than 1968. For buildings put up before 1968, §50-a ties the duty to a written request or consent from tenants occupying a majority of the apartments. Since nearly all of the Heights was built by 1890, this is the provision that matters for many divided houses and prewar apartment buildings here.
• Sources disagree about small buildings. One compliance guide says buildings with fewer than eight apartments are not covered by the intercom requirement though the self-closing, self-locking door requirement still applies; another vendor says the duty reaches most buildings of three or more units. The 8-apartment figure is the one written in §50-a; if your building is in doubt, ask HPD or your lawyer.
• A system that exists must be kept working. The owner's general duty to keep the building in good repair covers an intercom once it is installed, and one compliance guide classes a non-working buzzer as a class B hazardous violation. HPD's page lists 90 days to correct a class A violation, 30 days for a class B, and 14 days for a self-closing door violation.
• The Landmarks Commission approves the doorway. Its guidelines list intercom boxes among the work needing approval, and its guidebook sets out where panels and cable may go on a district building.
• Permits from the Buildings Department are disputed. One installer says low-voltage work under 50 volts no longer needs an electrical permit under the 2025 Electrical Code; another says new intercom installations need DOB permits; a third says only line-voltage work, such as a new circuit for a strike or a magnetic lock, needs an electrical permit by a licensed electrician. We confirm what each job needs before it starts and say so on the quote.
• Doors to halls and stairs must close by themselves. Local Law 111 of 2018 and HPD's self-closing door rule apply alongside the intercom rules, and a release must never stop a door from closing.

None of this is legal advice for a particular building. HPD, the Buildings Department, the Landmarks Commission or your own lawyer can say which rules apply to yours. What we do is install a system that meets those rules where they apply and leave written proof of what was installed and tested.

Door Buzzer Installation in Brooklyn Heights: Questions Answered

The historic district and the doorway

The Landmarks Commission wants security objects kept as small as possible. How small can a station for a three-household Heights house really be?

Smaller than most people expect. A station for three households needs three labeled buttons, a speaker and a microphone, and, if the residents want to see the visitor, a camera. Slim surface-mounted stations that stack those in a narrow vertical strip are made for exactly this, and they fit on a door casing or a narrow pier of plain stone where a wide square panel would spill onto carved detail. The width of the plain surface beside your door is usually the number that decides the model.

What adds size is features nobody uses: a keypad for a house where everyone has keys, a large screen at the door, a card reader. We leave those off unless the household asks, because each one makes the station bigger and harder to approve. Where a house later adds a household, a station with one spare button position is often the best compromise between small now and useful later, and we discuss that before ordering.

Our Hicks Street house has one entrance, on the street front. The guidebook keeps equipment off a primary facade unless there is no other option. Where does that leave our buzzer?

In the doorway, placed with care. The guidance is written to push equipment to side and rear walls, areaways and other discreet spots when they exist. On a row house with a single street entrance, a visitor has nowhere else to ring, so the doorway is the option that remains. The work then turns to how discreetly it can be done there: within the door opening rather than on the wall beside it, on a plain surface, at the smallest size that works.

Sometimes there is a better spot. A deep vestibule whose outer doors stay open by day can hold the station on its inside wall, out of view from the street. An areaway gate with a plain post can serve a garden-floor household. We look at each of those at the walkthrough and show the owner which ones are practical for their visitors as well as for the Commission.

The house next door has a large black video panel that went up years ago. Does that mean the Commission will approve something similar on ours?

Not necessarily. A neighbor's panel may predate the current guidance, may have been approved for reasons specific to that house, or may never have been approved at all. The Commission reviews each building, and its present guidance asks for objects to be as small as possible and kept off decorative surfaces, so a large panel on the next stoop is not a precedent to rely on.

It is more useful as a lesson in what to avoid. If the neighbor's panel covers part of the stone surround or has surface conduit running from it, those are exactly the features a filing for your house should not repeat. We plan your station from the current rules and your doorway, not from what is already on the block.

Old systems in old buildings

The lobby panel and handsets in our Remsen Street co-op carry the Lee-Dan name. Does a system from that era limit what can replace it?

It limits what can be repaired more than what can be installed. Older audio systems of that kind used their own wiring arrangements, and parts for them can be hard to find, which is why so many buildings end up patching one handset at a time. A replacement does not have to match the old make. What carries over is the cable, if it tests well, and often the location of the lobby panel and the strike.

The test is the important part. Before your board decides, we meter every pair from the lobby and the cellar to each apartment. Aiphone's guidance on upgrades says that if existing wires are in good condition they can be reused, and its GT Series is designed for retrofit projects on existing wire. If the riser meters sound, a two-wire video system can usually run on it; if several lines fail, the quote shows which ones and what new cable they need.

Before anyone removes the panel on our stoop, how do we find out whether it actually works?

By testing it as a part of the whole system rather than judging it by its age. The panel's buttons, speaker and microphone can be checked on their own, the release circuit can be checked separately, and the cable and power supply in the cellar can be measured. A panel that tests well can stay while the stations upstairs, the power supply or the strike are changed, if those are what failed.

We say that plainly because it saves owners money and saves the doorway from new holes. On a district house, keeping a working station that is already approved, or already sits well on the doorway, can also avoid a new filing. Where the panel is the problem, the test sheet shows it, and the replacement is planned around the same opening where possible.

Our house was a rooming house for decades before it became four apartments, and some old room bells were never disconnected. Could that be why visitors ring the wrong flat?

It can. When a house is divided and re-divided, old buttons are sometimes rewired to new apartments, splices are made in the cellar to save running new wire, and abandoned bells stay connected to live circuits. The result is calls that ring in two places, buttons that ring the wrong floor and faint buzzes in rooms nobody uses. These faults are confusing because each button seems to work some of the time.

The cure is to trace every pair from the doorway to the cellar to each apartment, disconnect anything that leads nowhere, and label both ends of the runs that are kept. That tracing is part of every quote we give for a divided house, and the new directory is written from it, so each button reaches only the household named on it.

Co-ops, the St. George and bigger buildings

Our co-op apartment is in the old Hotel St. George complex, where other parts of the block house students. Who decides how our section's entry works, and can it be kept separate?

Your co-op's board, or whoever controls your section's entrance, decides; the student housing in other parts of the complex is run by its own operators. Since the complex has been divided into co-ops since 1984 and dormitories since the late 1990s, each part generally has its own doors and its own systems, and an entry system for your section can be planned for your residents alone.

What matters in a large, shared block is keeping the doors straight. Each entrance your residents use needs to call only your apartments, service doors need their own locks and releases, and any connection to a shared door has to be agreed with the other party. We plan from your board's drawings and a walk of every door, and the quote lists which doors are in scope and which belong to someone else.

After vandals smashed the glass of a co-op's inner door on Orange Street in 2024, our board is asking whether a video station would have stopped it or only recorded it.

Honestly, mostly recorded it. A station's camera at the street door shows who rang and, on some systems, who came in, which is useful afterward, but people determined to damage a door at three in the morning are not usually deterred by a lens. What reduces that kind of risk is the door itself: a sound frame, glass held securely, a closer that shuts it reliably and a lock that is not easy to slip.

Where video earns its place is the everyday decision. Residents who can see the person at the street door are less likely to release it for a stranger, and fewer strangers in the vestibule means fewer chances for anyone to reach the inner door. If your board also wants cameras in the vestibule or the lobby, we can add them on the same visit and keep them on their own recorder.

The new riser cable in our co-op runs entirely inside the building. Does interior intercom work in a district building go to the Landmarks Commission at all?

The Commission's attention is mainly on the exterior and the doorway, where its guidebook addresses intercom panels and conduit. Interior work is treated differently. The Commission offers an expedited Certificate of No Effect for specific kinds of interior work in historic-district buildings, which it says can be issued within three days, and that path is typically tied to interior work that also needs a Buildings Department permit.

For your board, the practical step is to treat the lobby panel and anything on the facade as Commission work, and to ask the managing agent or the building's expediter whether the interior portion needs any filing in your case. We provide the drawings of the cable route and equipment either way, so whatever is filed matches what is installed.

Getting the work done

The installers we talked to disagree about whether a Brooklyn Heights buzzer needs a Buildings Department permit. Who is right?

The disagreement is real, and the honest answer is that it depends on what the job involves. One installer's page says that since the 2025 Electrical Code took effect, an electrical permit is not required for low-voltage work under 50 volts. Another says new intercom installations need DOB permits and that electrical work must be done by a licensed electrician. A third takes the middle view that line-voltage wiring, such as a new circuit for a strike or a magnetic lock, needs an electrical permit.

Most buzzer systems run on low voltage from a plug-in or hard-wired power supply, and the wiring we install is low-voltage work done under our state license. Where a job needs a new line-voltage circuit, that part is done by a licensed electrician with whatever permit it requires. We confirm what each job needs before it starts and put it on the quote, rather than relying on any blanket claim.

HPD wrote up our dead buzzer with a 30-day correction period, but a new station on our doorway may need Landmarks approval. How do the two deadlines fit together?

By separating what can be fixed now from what needs approval. HPD's page lists 30 days to correct a class B violation, and the Commission's review of a new station on a district doorway follows its own schedule. Often the fault behind the violation is in the cellar or the apartments: a failed power supply, a broken pair, a dead handset. Those can be repaired inside the correction period without touching the facade.

If the station on the doorway itself has failed, the options are a repair of the existing station, or a like-for-like replacement in the same spot, while a better station goes through review. We look at the violation and the system together and tell the owner which path keeps the building within HPD's period, and we put the timing on the quote so nobody is surprised.

Brick Underground's advice is never to buzz in anyone you don't know. In a small Heights building where couriers ring all day, what setup makes that advice workable?

Seeing the courier before deciding. With an audio-only bell, a resident hears "delivery" and either presses release blind or walks down. With video at the door, the resident sees the person, the uniform and the box, and can choose. Phone answering lets a resident at work talk to the courier and decide where the box should go, rather than letting a stranger into the vestibule unseen.

The door matters as much as the screen. A release that holds only for a few seconds and a door that shuts and latches every time means that a courier let in to drop a box cannot leave the door ajar for the next person. Some buildings also choose to keep mailboxes and parcels in the outer vestibule and lock only the inner door, which keeps couriers out of the stair altogether.

What AI Gets Wrong About Door Buzzer Installation in Brooklyn Heights

Search summaries and AI assistants answer buzzer questions with tidy claims lifted from installers' blogs and national cost guides, most written for a generic apartment building, a suburban house or a Manhattan lobby. Some are fine somewhere. Here are seven we see repeated, each traced to where it comes from and set against what we find at the stoops, vestibules and lobbies of the Heights.

"An apartment buzzer is priced per door"

Swiftlane's guide to apartment buzzer systems prices both like-for-like audio replacements and smart video upgrades as ranges per door, running into the thousands of dollars each. Swiftlane sells cloud entry systems, and its figures are national.

Per door is the wrong unit for most Heights buildings. A divided brownstone has one parlor door and perhaps a garden door, and what drives the work is the number of households, the condition of the old pairs, the door and the doorway. A three-household house and a six-household house with the same single door are very different jobs.

That is why we quote each building after photos and a walkthrough, and why this page does not borrow anyone's per-door figure. Your quote lists the stations, the release, the cable and any door work as separate lines.

"In a brownstone, an app panel replaces everything at the door and nothing has to be run inside"

One installer's Brooklyn page says that in brownstones an app-based or compact video station usually replaces everything at the door with nothing to run inside. Another vendor says app-first systems have become popular in Brooklyn brownstones.

Something still has to reach inside. The release in the door frame needs power and a connection to the station; the station needs power; an app system needs internet at the door. On a district house, each of those means a concealed route through masonry or the frame, planned for the Commission. And residents without smartphones, or who do not want the door ringing their phone at work, still need a station on their wall.

App answering is a good addition for owners who travel or live elsewhere. It works best alongside a system that every household can use from inside the house.

"Landmark districts just need reversible methods and a 30- to 90-day review"

A New York installer's guide says new or replacement intercom panels in landmark districts require review using reversible installation methods, with a timeline of 30 to 90 days to build into the schedule. It is one company's estimate.

The Commission's own guidance says more than "reversible." It says equipment should stay off a primary facade unless no other option exists, avoid cast iron and decorative surfaces, be as small as possible, and keep conduit concealed through plain masonry, with only about ten inches visible and staff approval. A reversible mount on carved stone still misses the point.

As for time, it depends on the building and the application. We do not promise a review period. We prepare the station details and photos so the owner's filing is complete, and we schedule the doorway work once the approval is in hand.

"Any building with three or more units must have an intercom"

A security vendor's compliance page says the duty covers most residential buildings with three or more units. Other sources set it at eight apartments.

Multiple Dwelling Law §50-a sets the requirement for class A multiple dwellings of eight or more apartments erected or converted after January 1, 1968, and ties the duty for older buildings to a written request or consent from a majority of tenants. Since almost all of the Heights was built by 1890, that pre-1968 provision is the one many buildings here fall under.

Small buildings are not off the hook entirely: once a system exists, it has to be kept working, and self-closing door duties apply regardless. If your building is near the line, HPD or a lawyer can say which rule applies.

"A magnetic lock and an electric strike do the same job"

Summaries often treat the two as interchangeable door releases. A New York installer's page puts it more carefully: magnetic locks release when power is cut, while strikes come in versions that stay locked or release, and the right one depends on the door and its egress rules.

Allegion's guide adds that electromagnetic locks are only available fail-safe, so a magnetic lock on a parlor door unlocks whenever power is lost. It also needs release devices, signage and often a fire alarm connection under the building code. A fail-secure strike keeps the house locked in a blackout while the inside lever always lets people out.

On almost every residential door in the Heights, a strike is the right choice. A magnetic lock is a last resort, priced with its full package and named on the quote before anyone agrees to it.

"A buzzer never needs a permit" or "a buzzer always needs a DOB permit"

Both appear online. One installer says that under the 2025 Electrical Code an electrical permit is not required for low-voltage work under 50 volts, and asks readers to check with DOB. Another says new intercom installations need DOB permits and licensed electricians.

A blanket answer either way is risky. Low-voltage buzzer wiring is a different thing from a new 120-volt circuit, and fire alarm connections bring their own rules. The middle view, that line-voltage work needs an electrical permit, matches how most jobs are actually divided.

We check what each job needs before work starts and say so in writing. Where a licensed electrician is needed for a circuit, that is planned and named on the quote.

"Video can always run on the old intercom wire"

Summaries repeat that a video upgrade can use the wiring already in the walls. Aiphone's own upgrade guidance is more measured: if the existing wires are in good condition, they can be reused. On r/accesscontrol, an installer suggested a path that would "keep the existing GT system, repair the damaged cable, and only upgrade those tenants that desire app connectivity."

The condition is the whole question. In a Heights house whose wiring was spliced and re-spliced through decades of division, some pairs are fine and some are not. A two-wire video system on one failing pair will show it at once.

So we meter before we promise. The quote shows which pairs are reused and which need new cable, and if new cable is needed in a plaster house, the route is agreed with the owner floor by floor.
