Hikvision and Dahua are the two largest CCTV manufacturers in the world, and in the UK both are sold through the same trade and online channels — often installed by the same local installers. If you're comparing them for a home PoE camera system, the practical differences come down to AI detection features, price at a given resolution, and how well each integrates with an open platform like Home Assistant via ONVIF and Frigate. This guide compares both ranges directly, plus the government guidance that applies to both brands equally.
Company and product range overview
Hikvision's consumer/prosumer range centres on its ColorVu (full-colour low-light) and AcuSense (AI person/vehicle filtering) camera lines, controlled through the Hik-Connect app or a local NVR. Dahua's equivalent is the WizSense range, which bundles similar AI-based human/vehicle detection into its mid-range fixed and PTZ cameras, controlled via the gDMSS/DMSS app or a Dahua NVR. Both companies sell overlapping product tiers — fixed bullet and dome cameras, PTZ models, and PoE NVR kits — through the same UK CCTV trade resellers, so pricing and spec sheets are usually the more useful comparison point than brand loyalty.
Pricing in the UK
At the entry level, both brands sell 4–6MP fixed AI cameras from UK CCTV resellers in a similar £80–£150 range, rising to £250–£350+ for higher-resolution or long-zoom PTZ models. Dahua's WizSense range tends to undercut the equivalent Hikvision ColorVu/AcuSense model slightly at the budget end, but the gap narrows or reverses at higher resolutions and with PTZ models — it's worth comparing specific SKUs (resolution, lens, IR/full-colour range) rather than assuming one brand is reliably cheaper across the board, since both ranges span a wide price spread.
AI detection features
Both AcuSense and WizSense use onboard AI processing to filter false motion alerts from people and vehicles, cutting down the number of notifications triggered by trees, shadows or passing cars compared with older PIR-only motion detection. In practice, reviewers and installers report the two are broadly comparable at this task on mid-range cameras — the bigger differentiator tends to be low-light performance (Hikvision's ColorVu full-colour night imaging is a strong point of that specific line) versus overall value at a given price point (where Dahua's WizSense range is often positioned more aggressively). Neither brand's AI detection is dramatically ahead of the other across their full ranges.
ONVIF, Frigate and Home Assistant integration
Both brands are ONVIF-compliant, which is what makes them usable with an open NVR platform instead of the manufacturer's own app. Dahua's ONVIF compliance was briefly disputed after a 2024 dispute with the ONVIF organisation but has since been confirmed as reinstated, with Dahua's IP cameras and NVRs continuing to support the standard. Hikvision's ONVIF support has been consistently available across its camera range. For a local, self-hosted setup, both brands work with Frigate — Home Assistant's open-source NVR add-on for AI object detection — over RTSP, and Home Assistant community threads document working setups for both Hikvision and Dahua cameras via ONVIF/RTSP rather than the manufacturers' cloud apps. See our Frigate NVR with Home Assistant setup guide for the full walkthrough, and our best wired security camera system UK guide for PoE NVR kits from both brands and others.
UK government guidance — applies to both brands
In November 2022 the UK government instructed departments to stop installing cameras made by Hikvision and Dahua on "sensitive sites", following a review into the security and human rights record of Chinese-owned surveillance equipment suppliers. The GOV.UK announcement and subsequent BBC News coverage confirm this restriction applies to both brands equally, not just Hikvision — and Hikvision has separately confirmed in its own newsroom statement that the restriction does not extend to the wider public sector or private/residential use. For a domestic install, this guidance doesn't prohibit purchase or use, but it's worth being aware of if you're specifying cameras for a business premises with any government contract exposure, where the same sensitive-sites restriction would apply regardless of which of the two brands you choose.
Which should you buy?
For a home system prioritising the best possible low-light colour footage, Hikvision's ColorVu line is a strong specific pick. For the best AI-camera value at a given price point, Dahua's WizSense range is usually worth cross-shopping before you commit. Both integrate equally well with Frigate/Home Assistant via ONVIF, and both are subject to the same government sensitive-sites guidance — so for a residential install, the decision mostly comes down to comparing the specific camera model, resolution and price rather than the brand name itself. Our full Hikvision camera UK review covers the ColorVu/AcuSense range in more depth if you've already leaning that way.
