Hikvision vs Dahua:
Which Security Camera System Is Better?

The two-minute version. Hikvision and Dahua are the two large Hangzhou camera makers whose equipment fills a remarkable share of New York's basements, lobbies and storefront ceilings. Their professional cameras are close cousins on paper. Hikvision's DS-2CD2387G2-LSU/SL is an 8MP turret with an F1.0 lens, white light out to 30 meters, a strobe and a speaker, a microSD slot up to 512 GB and an IP67 metal housing. Dahua's IPC-HDW3849H-AS-PV-PRO is an 8MP eyeball with an F1.0 lens, infrared and warm light out to 30 meters on the 2.8 mm lens, red and blue warning lights and a speaker, a microSD slot up to 512 GB and an IP67 housing. Put one of each on the same alley wall and most owners would struggle to say which picture came from which brand. That is why the honest comparison in 2026 is not really about pixels.

It is about three things that sit outside the camera. The first is federal status. Both companies have been on the FCC's Covered List since March 12, 2021, for equipment used for public safety, government facilities, critical infrastructure and other national security purposes. In June 2026 the FCC went further and prohibited the continued importation and marketing of already-authorized covered equipment for those purposes, while saying plainly that people may keep using equipment they already own. The second is the company behind the box in the United States. Hikvision still publishes a US warranty table with up to 60 months on its professional cameras and recorders. Dahua's American operations were transferred to Luminys Systems Corporation, which says it honors Dahua Technology USA's existing warranties and service agreements. The third is the security history of the equipment on your wall, because each brand has a flaw in the federal catalog of vulnerabilities known to be exploited, and an unpatched recorder is a real risk whatever logo is on it.

So the rule we give New York owners is short. If you have a working Hikvision or Dahua system in a private home, shop or apartment building with no government tenant, you can keep using it, and repairing or extending it is often the cheapest sound choice, as long as the firmware is current and the recorder is not exposed to the internet. If you are starting from nothing, we would rather quote a brand that is not on the Covered List, and we will show you that price next to what a Hikvision or Dahua extension would cost. If the building has any federal, state or city tie, a public safety function, or a lender or insurer asking about the Covered List, we do not install either brand there. Between the two, Hikvision is the easier one to support for the long haul in the United States today, and Dahua remains a sound camera for owners who already have it. The rest of this page explains each edge of that rule.

The Covered List, Section 889 and the FCC's June 2026 Import Rule, in Plain English

No part of the Hikvision vs Dahua question causes more confusion in New York than the federal rules, and no part is more often explained badly. Forum posts swing between "nothing has changed" and "both brands are illegal now." Neither is right. There are three separate federal layers, each with its own reach, and the brands are treated identically under all three. Here they are in the order they arrived.

Layer one: Section 889 and federal buying

Section 889 of the John S. McCain National Defense Authorization Act for Fiscal Year 2019 is carried into federal contracts by clause 52.204-25 of the Federal Acquisition Regulation. That clause defines covered equipment to include, "for the purpose of public safety, security of Government facilities, physical security surveillance of critical infrastructure, and other national security purposes, video surveillance and telecommunications equipment produced by Hytera Communications Corporation, Hangzhou Hikvision Digital Technology Company, or Dahua Technology Company (or any subsidiary or affiliate of such entities)." Two prohibitions follow. A contractor may not provide the government any equipment, system or service that uses covered equipment as a substantial or essential component. And under the second part, the prohibition "applies to the use of covered telecommunications equipment or services, regardless of whether that use is in performance of work under a Federal contract." The clause also flows down into subcontracts.

In everyday terms, Section 889 is aimed at the federal government's own buying and at the companies that sell to it. A private homeowner in Bay Ridge is not a federal contractor. A medical practice in Midtown that bills federal programs, a construction company with a federal job in the pipeline, or a nonprofit with a federal grant may well be bound by contract terms that reach the cameras in their own offices, and those owners should read their agreements or ask their contracting officer before buying either brand.

Layer two: the FCC Covered List

The FCC keeps a list of communications equipment and services that a national security agency or Congress has found to pose an unacceptable risk. On March 12, 2021, it added "video surveillance and telecommunications equipment produced by Dahua Technology Company, to the extent it is used for the purpose of public safety, security of government facilities, physical security surveillance of critical infrastructure, and other national security purposes, including telecommunications or video surveillance services provided by such entity or using such equipment." The Hikvision entry, for Hangzhou Hikvision Digital Technology Company, has the same date and the same words. A footnote on the FCC page adds that the listing should be read to include subsidiaries and affiliates. The list we read was dated November 6, 2026, and both entries were unchanged.

The phrase that matters is "to the extent it is used for the purpose of." These are use-based entries. Other entries on the same list, such as the ones for Huawei and ZTE telecommunications equipment, are not limited that way. For Hikvision and Dahua, the FCC tied the listing to what the equipment is used for. That is why we keep telling private owners that the list is not, by itself, an instruction to rip out a working system.

Layer three: equipment authorization and the 2026 import and marketing rule

Almost every electronic device sold in the United States needs an FCC equipment authorization. In its 2022 rules, the FCC stopped new authorizations for covered equipment. For the use-based entries, the FCC's June 2026 notice explains how that played out: new authorization applications from those manufacturers "are generally prohibited until those manufacturers have submitted, and received Commission approval for, compliance plans," and "the Commission has yet to approve any such compliance plans," partly because a federal appeals court in 2024 upheld the FCC's order but sent back its definition of "critical infrastructure" to be rewritten.

That left a gap: equipment authorized before the 2022 rules could still be imported and marketed. On June 26, 2026, the FCC's Public Safety and Homeland Security Bureau and Office of Engineering and Technology closed most of it in Public Notice DA 26-635. The notice prohibits "the continued importation and marketing of certain previously authorized covered equipment added to the Covered List in 2024 or earlier," effective ten days after Federal Register publication. The summary appeared in the Federal Register on July 6, 2026, so the rule took effect in mid-July. For use-based listings like Hikvision's and Dahua's, the FCC wrote that importation and marketing "will only be prohibited if imported or marketed for the purpose of" public safety, government facilities, "other national security purposes," and physical surveillance of critical infrastructure, with that last purpose suspended until the FCC adopts a new definition of critical infrastructure.

The same notice is equally plain about people who already own the equipment: the prohibition "will not affect the continued use or operation of already-purchased communications equipment." The Federal Register summary puts it in consumer terms: people "may continue to use any device or equipment that they currently possess, if the equipment was legally purchased and maintains an existing equipment authorization." It also explains why replacements are caught: "Allowing imports and marketing replacements for existing covered equipment would defeat the entire purpose of this prohibition." Hikvision argued in the proceeding that the FCC lacked authority to do this; the FCC noted its "continued disagreement" and went ahead.

What the three layers mean on a New York block

For a family in a semi-detached house in Marine Park with a Hikvision recorder in the den, nothing in the three layers stops them from using it, and nothing requires them to remove it. For a deli in Jackson Heights with a Dahua kit over the register, the same is true. For a building that houses a city agency office, a public school program, a police-related tenant, a utility facility or a federal contractor, the picture changes quickly, because those are exactly the uses the listings name. Those owners should plan to move to a brand that is not on the list, and we will not install new Hikvision or Dahua equipment there.

The part that does affect ordinary owners is supply. When the authorization door closed in 2022 and the import and marketing door narrowed in 2026, the practical availability of new Hikvision and Dahua cameras and recorders through ordinary US channels became less predictable. We do not claim to know which individual models any distributor still stocks on a given day, and we will not guess on this page. What we can say is that when a camera on a Hikvision or Dahua system fails, we check what is available legally and in stock for that purpose before quoting a like-for-like swap, and if the answer is unclear, we quote an ONVIF camera from another maker that the existing recorder can still record.

Who Should Stay With Hikvision, Who Should Stay With Dahua, and Who Should Pick Neither

Hikvision is the better fit if

• You already have a Hikvision recorder that works and you want to add, replace or re-aim cameras without starting over.
• You want a published US warranty term on professional equipment you already own: Hikvision's US table lists 60 months for professional IP cameras and 9 Series professional recorders.
• Bright, color video at night on a dark side yard or back lot matters most, and a steady white light on motion is acceptable to the neighbors.
• Several people in the family or the building staff already use Hik-Connect and you would rather not retrain them.
• The building is private and has no government tenant, public safety use or federal contract tied to it.

Dahua is the better fit if

• You already have a Dahua recorder and cameras that work, and the DMSS app is how you check the store or the house.
• Your storefront relies on the red and blue warning lights and the siren to move people along from the gate after closing, and you want the same behavior on a new camera at the back door.
• You want a camera rated down to −40°F for an exposed roof or a rear yard with no shelter, which is lower than the Hikvision turret we compared.
• You have an existing Dahua Technology USA warranty claim and want it handled through Luminys, which says it honors those commitments.
• Again, the building is private, with no government tie.

When we would steer you to neither

If you are buying a brand-new system from nothing, we start with brands that are not on the FCC Covered List: our own non-branded recorder systems, Luminys, Uniview, Hanwha or UniFi, depending on the building. The cameras are comparable for most New York jobs, the prices on our lists are in the same range as a Hikvision or Dahua build, and you avoid every future conversation with a board, a buyer's lawyer or an insurer about the list. If your building has any government, public safety or critical-infrastructure connection, the answer is neither, full stop. And if your Hikvision or Dahua recorder is old enough that its firmware can no longer be updated against the flaws in the federal catalog of exploited vulnerabilities, we will recommend replacing the recorder even if the cameras stay.

Smart Detection: Hikvision AcuSense vs Dahua WizSense

The single biggest complaint we hear from owners of older camera systems of any brand is the phone that buzzes forty times a night because a tree moved, headlights swept across the wall or rain hit the lens. Both companies answered that complaint the same way, by putting a person-and-vehicle classifier in the camera. Hikvision brands it AcuSense; Dahua brands it WizSense. The names are different, the goal is the same.

Hikvision's detection tools

The Hikvision turret we compared lists line crossing, intrusion, region entrance and region exit as smart events, each of which can be set to trigger only on "specified target types (human and vehicle)," along with ordinary motion detection with the same filter and face capture. On its Pro Series page, Hikvision says its newest version, AcuSense 3.0, "reduces typical false alarms—such as lights reflecting on stationary vehicles—by up to 90%," and pairs with back-end tools it calls AcuSeek and AcuSearch for faster searches by text and image. That 90 percent figure is Hikvision's claim, not a measurement of ours. The recorder we compared, the DS-7608NXI-K2/8P, adds its own analysis: perimeter protection with human and vehicle recognition on two channels at 4MP, and what Hikvision calls Motion Detection 2.0 on all channels.

Dahua's detection tools

The Dahua eyeball we compared lists tripwire, intrusion, stay detection, loitering detection, face detection, audio detection, scene changing and what it calls SMD, Dahua's smart motion detection, among its alarm events. Loitering and stay detection are useful extras in New York, where the problem at a store gate or a building vestibule is often not someone passing through but someone who settles in for an hour. Dahua's WizSense recorders, like the NVR4108HS-8P-EI, add face recognition at the recorder level.

How we set either one up so it stays quiet

The classifier only helps if the zones are drawn well. On a typical brownstone stoop we draw the line across the top step, not the sidewalk, so a passing dog walker never triggers an alert but a person climbing to the door always does. On a storefront we set the intrusion zone to the space between the gate and the glass after closing hours only, so customers do not set it off during the day. In a lobby we use line crossing on the inner door so the camera alerts on people entering, not people leaving. On either brand, the tuning takes longer than the mounting, and it is the part most do-it-yourself installs skip. It is also the part that decides whether you keep checking the alerts or switch them off in the first month.

Recorders and Storage: Hikvision NVRs vs Dahua NVRs

Both brands are built around the same idea: cameras on network cable, powered over that cable, recording to a network video recorder with a hard drive in a closet, a basement or a locked cabinet. There is no monthly fee in that design. Video stays on the property, and you watch it on a phone through the brand's app or on a monitor plugged into the recorder.

The Hikvision recorder we compared

The DS-7608NXI-K2/8P is described by Hikvision as an "8-ch PoE 1U K Series AcuSense 4K NVR." It accepts eight IP cameras, has 80 megabits per second of incoming bandwidth, a 4K HDMI output and a VGA output, two-way audio, and records cameras up to 12MP. Its decoding capacity with AI turned on is listed as one camera at 12MP, two at 8MP, four at 4MP or eight at 1080p, all at 30 frames per second. On Hikvision's Saudi regional page that exact model is now marked "Discontinued," which tells you something about how quickly these product lines turn over; it is still the model we find most often in eight-camera buildings.

The Dahua recorder we compared

The NVR4108HS-8P-EI is Dahua's eight-channel compact recorder with eight PoE ports and one drive bay that takes a drive up to 20 terabytes. Dahua lists 256 megabits per second of bandwidth, support for cameras up to 16MP, and decoding of sixteen 1080p streams or four 8MP streams at 30 frames per second, along with face recognition.

How long a recorder actually keeps video

The number that matters more than either spec sheet is how many days of video the drive holds before it starts writing over the oldest footage. That depends on the number of cameras, their resolution, the compression, whether they record all the time or only on events, and the size of the drive. Both brands support H.265 and their own smarter compression modes, which Hikvision calls H.265+ and Dahua calls Smart H.265+, and both cut drive use a great deal compared with older H.264 recording. When we take over a building's existing system, the first thing we do is open the recording settings and work out the real number of days, because we regularly find recorders set up to keep three or four days when the owner believed it was a month. On our new installs we size the drive so the system keeps at least two weeks.

Recording on the camera too

Each camera we compared also takes a microSD card up to 512 GB. Hikvision calls the feature that uses it auto network replenishment: if the cable to the recorder is cut, the camera keeps recording to its card and fills the gap on the recorder later. It is a small extra cost per camera, and on a building where someone might pull the recorder's network switch, it is worth it on either brand.

Patches and Hacks: Each Brand's Entry in the Federal Exploited-Flaws Catalog

Every network device has security flaws discovered over its life. What matters is whether the maker fixes them and whether owners install the fixes. The federal Cybersecurity and Infrastructure Security Agency keeps a catalog of flaws it knows are being exploited in the real world, and each of these two brands has at least one well-known entry in it. We name them here because they are the reason an unmaintained recorder in a basement is a genuine risk, not because either brand is uniquely careless.

Hikvision: CVE-2021-36260

The National Vulnerability Database describes CVE-2021-36260 as a command injection flaw in the web server of some Hikvision products. CISA added it to its catalog on January 10, 2022, under the name "Hikvision Improper Input Validation," with the required action "Apply updates per vendor instructions." In plain terms, Hikvision released firmware that fixes it, and a camera or recorder that has never been updated may still be open to it.

Dahua: CVE-2021-33044

The National Vulnerability Database describes CVE-2021-33044 as "the identity authentication bypass vulnerability found in some Dahua products during the login process," where attackers "can bypass device identity authentication by constructing malicious data packets." CISA added it to its catalog on August 21, 2024, as the "Dahua IP Camera Authentication Bypass Vulnerability," with the required action "Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable." That wording, discontinue use if no fix is available, is stronger than the Hikvision entry's, and it matters for owners of older Dahua equipment whose firmware may no longer be updated.

What we do on every Hikvision or Dahua system we touch

• Check the firmware version on the recorder and each camera, and update to the maker's current release where one exists for that model.
• Close any port forwarding on the building's router that exposes the recorder's web page to the internet, and use the brand's app connection instead.
• Replace default and shared passwords with strong, unique ones, and set up separate user accounts instead of one login passed around the building.
• Put the cameras on the recorder's own PoE ports or a separate network segment, so they cannot be reached from the building's guest Wi-Fi.
• Turn off services the building does not use, such as unencrypted web access or old remote-access features.
• Write down what we changed and hand it to the owner, so the next technician does not undo it.

If a recorder is too old to receive a fix for the flaw that affects it, we say so in writing and quote a replacement recorder. On a Dahua unit affected by CVE-2021-33044 with no available mitigation, CISA's own wording is the reason we will not leave it running on a network as-is.

Can Hikvision and Dahua Work Together, or With Another Brand?

Yes, within limits, and this is one of the most useful facts on the page for owners with a working recorder. Both cameras we compared list ONVIF Profile S, Profile G and Profile T. ONVIF is an industry standard that lets a camera from one maker send video to a recorder from another, Profile S covers live video, Profile G covers recording and playback on the device, and Profile T covers newer video formats and features. In practice, an ONVIF camera from almost any professional maker can be added to a Hikvision or Dahua recorder, and a Hikvision or Dahua camera can be added to most other recorders.

The limits are the smart features. Basic live video and recording cross over cleanly. Person-and-vehicle alerts, deterrence lights, two-way talk and some of the newer search features often work fully only when the camera and recorder come from the same maker, because each company uses its own protocols for them, Hikvision's ISAPI and Dahua's own interfaces, alongside the open standard. When we add a third-party camera to an existing Hikvision or Dahua recorder, we test each feature the owner cares about before calling the job done, and we tell them in advance which ones may not carry over.

This is why we can often save an owner money. If a building has a sound eight-channel Hikvision recorder and three failed cameras, we can replace those cameras with ONVIF cameras from a maker that is not on the Covered List, keep the recorder and the cable, and push the bigger replacement decision a few years down the road. The same works for a Dahua recorder. When the recorder itself eventually needs replacing, the newer cameras move to the new recorder with it.

Hikvision or Dahua for Each Kind of New York Property

Brownstones, row houses and attached homes

The typical setup is a camera over the stoop, one at the garden-level door, one or two at the back yard and a recorder in the cellar. Either brand handles that well. If you already own one, keep it and extend it. On attached homes we are careful with lights and sound on both brands: Hikvision's white light and Dahua's red and blue flash both reach the neighbor's windows on a row of attached houses, so we schedule and aim them tightly.

Detached and semi-detached houses

Houses in Staten Island, southeast Queens and the outer parts of Brooklyn often have long driveways and dark side yards, which is where color at night earns its place. Hikvision's turret with its white light is strong on a driveway; Dahua's warm light is gentler on a side yard. For a new system on a house with no existing equipment, we would still start with a brand that is not on the Covered List, but if the house already has either brand working, keeping it is reasonable.

Walk-ups and small apartment buildings

Many walk-ups in Bushwick, Washington Heights, Sunset Park and the Bronx have a Hikvision or Dahua recorder installed years ago by a previous super or contractor, often with no record of the password. Our first visit there is usually recovery: regain access, update firmware, fix retention and document everything for the owner. After that, extending the system is cheaper than replacing it in most cases.

Co-ops and condo buildings

Boards ask the Covered List question more than anyone. For a private co-op with no government tenant, the honest answer is that the FCC does not require removal. Some boards decide to replace anyway, to remove the question from future sales, refinancings and shareholder meetings, and that is a legitimate choice we will quote. When a board asks, we give them the FCC's own wording in writing so the decision rests on the source rather than on a rumor.

Stores, delis, restaurants and salons

This is where Dahua's TiOC deterrence cameras show up most often, and where store owners are most attached to them. If yours works, keep it, secure it and schedule the lights and sound for closed hours. Hikvision's strobe-and-siren turrets do the same job. For a new store system, we quote a brand off the Covered List with similar deterrence features.

Offices and medical suites

Offices are where Section 889 most often reaches a private business without the owner realizing it, through a federal contract, a subcontract or a grant. Before we touch the cameras in an office, we ask whether the business sells to or takes money from the federal government. If it does, we recommend replacing Hikvision or Dahua equipment and we do not add to it.

Garages, warehouses and parking lots

Large open spaces favor cameras with wide views and long light reach, and both brands have strong options. Dahua's eyeball is rated to a colder −40°F, which is a small point in its favor on an unheated loading dock. If a lot or facility serves a utility, transit, a city agency or another critical-infrastructure function, neither brand belongs there.

Buildings with any government connection

A city agency office on the ground floor, a public school program, a police or fire department tenant, a federally funded clinic, a contractor's office doing federal work: in all of these, we do not install new Hikvision or Dahua equipment, and we recommend planning a replacement for any that is there. This is the one case where we do not offer a choice.

We Work on Both: Installed Prices in NYC

We install, repair and extend Hikvision and Dahua systems for private New York owners, and we install brands that are not on the Covered List for everyone else. These are the numbers from our own NYC pages. We never set them beside a store or manufacturer price, because an installed price includes the cable, the mounting, the recorder setup, the app and the visit, and a box price includes none of that.

Hikvision and Dahua systems

Our Hikvision camera installation page for NYC and our Dahua camera installation page for NYC both give the same range: an installed system runs about $400 to $700 per camera including the recorder, PoE cabling, configuration and app setup, with the per-camera cost dropping on larger jobs, and a small four-camera residential system often lands around $1,800 to $3,000. Larger commercial builds run higher with PTZ cameras, plate-reading cameras or high-channel recorders. Final pricing follows a free site visit. For extending an existing system, we quote per camera at the same rates, and we always check what equipment is legally available for that building before we quote a like-for-like brand swap.

The Dahua successor: Luminys

Our Luminys installed price list for NYC starts a four-camera Luminys system at $2,591 installed, with Luminys cameras from $465 each installed and recorders with setup from $502, and two weeks of recording always included. Prices there are plus sales tax and the page updates as our costs change, so check it on the day you are deciding.

Other brands off the Covered List

For owners who want to leave both brands behind, our Uniview price list starts a four-camera system from $2,334, and our UniFi price list starts one from $2,111. We also install Hanwha Wisenet systems and our own non-branded recorder systems, which are often the lowest-cost option for a straightforward house or store. Those numbers sit close to the Hikvision and Dahua range, which is one more reason we steer new systems away from the listed brands: the saving that once came with them has mostly gone.

What every quote includes

Whichever brand you choose, our written quote lists every camera and its mounting spot, the recorder and drive size with the number of days it will keep, the cable route and whether wiring is hidden or surface-run, the app setup for each person who needs access, and the price. If the existing system can be kept or extended, the quote says so and shows that option first. Our own workmanship and parts terms are covered in the warranty section above.

Already Have a Hikvision or Dahua System? Start Here

Before you call anyone, including us, take three photos: the label on the back or bottom of the recorder, the screen of the recorder if a monitor is attached, and one camera from the ground. Note roughly how many cameras there are, whether the picture on each one works, and whether anyone has the password. Then text or WhatsApp those photos to us. From the recorder label alone we can usually tell the brand, the model, how many channels it has and whether its firmware line is still supported, and from that we can tell you on the phone whether you are looking at a keep, a repair, a recorder swap or a full replacement. If you have lost the password, do not try factory resets you found online: on both brands that can wipe the recordings and the camera settings at once. We recover access through each maker's official process. Still comparing other brands? See our best security camera brands comparison, our Eufy vs Ring comparison and our Lorex vs Swann comparison.
