The Uniview IPC264EA-AHDZK-I1 / AHDX4K-I1 is a 4MP LightHunter WDR network bullet camera built on a 1/1.8" CMOS sensor with 140dB optical WDR and Wise-ISP processing for strong low-light and high-contrast image quality. It is available in two motorized 4X zoom variants: AHDZK covers 2.8-12mm for wide-to-normal coverage, while AHDX4K covers 8-32mm for telephoto reach with a detection range beyond 490 m. Both variants share PoE+ (802.3at) power, an IP67/IK10 outdoor-rated body, a built-in heater, and face recognition with up to 16 libraries.
Is this the right camera for you?
Plain-language guide for buyers and installers — based only on what this camera actually does.
Perimeters & long-range sitesPorts, highways and large compounds — AHDX4K's telephoto end detects objects out to roughly 497 m.
Access control & watchlistsFace recognition against up to 16 libraries and 100,000 faces, with blocklist/allowlist comparison.
Traffic & vehicle monitoringMetadata analysis captures and classifies motor vehicles and non-motor vehicles alongside people.
Retail & transit crowd analyticsBuilt-in people flow counting and crowd density monitoring for footfall reporting.
Cold or harsh outdoor sitesBuilt-in heater plus -40°C to 60°C rating, IK10 impact resistance, and IP67 keep it running through rain, dust and cold.
Sites needing on-site audioBuilt-in mic and speaker support two-way audio — warn or talk to visitors directly from the camera.
Not the right pick if you need…
- Wi-Fi — this is a wired RJ45 Gigabit camera, no wireless radio
- Battery or solar-only power — it needs DC 12V or PoE+ (802.3at) wired power
- One lens covering ultra-wide and super-telephoto at once — pick AHDZK (2.8-12mm) or AHDX4K (8-32mm), not both together
- Discreet or compact mounting — this is a full-size 406mm bullet body, not a mini/covert form factor

How wide a view at each distance
Scene width covered at typical mounting distances — the number you need to work out how many cameras a wall, yard or aisle takes.
| Distance | AHDZK · 2.8 mm · 106.6° | AHDX4K · 32 mm · 15.2° tele |
|---|---|---|

Calculated from the horizontal field of view in the specifications below: width = 2 × distance × tan(FOV ÷ 2). Lens distortion and mounting angle are not included.
Who uses it, where it goes and how to install it
Written for the IPC264EA-AHDZK-I1 / AHDX4K-I1 from its own specifications: 4 MP at 60 fps, 1/1.8" sensor, motorized 4X zoom (2.8–12 mm or 8–32 mm), 100 m IR, PoE+.
Who it is for
- Perimeter, port and highway projects — The AHDX4K at 32 mm detects out to 496.6 m by day and still identifies a face at 49.7 m, so one camera can watch a long fence line, a quay or a road approach.
- Installers who want one flexible model — The AHDZK zooms from 106.6° to 51.3°, so the same stock unit covers a wide yard or a narrower gate; the angle is set after mounting instead of guessed before ordering.
- Entrances that need face matching — Face recognition runs on the camera with up to 16 libraries and 100000 faces, with blocklist and allowlist comparison, for offices, factories and gated sites.
- Cold, dusty or exposed sites — Built-in heater, -40 °C to 60 °C rating, IP67 and IK10 body and 6 KV surge protection suit mines, farms, depots and mountain or desert locations.
- Parking, traffic and retail analytics — Metadata capture of people, motor vehicles and non-motor vehicles, plus people flow counting and crowd density, at 2688 × 1520 and up to 60 fps for fast-moving targets.
Where and how to install
- Pick the variant by target distance — If faces must be identified within about 17 m, the AHDZK is enough (6.8–16.6 m). For faces at 20–50 m or detection beyond 170 m, take the AHDX4K (identify 12.4–49.7 m).
- Height and angle — For faces, mount at about 2.5–3.5 m with a shallow tilt. For long-range perimeter views on the AHDX4K, a higher pole is fine because you look along the area, not down at people.
- Rigid mounting for telephoto — At 32 mm the view is only 15.2° wide, so any pole sway shows as a shaking picture. Use a solid wall or a thick, guyed pole. Pole: TR-UP06-C-IN-V2 (used together with the bullet junction box); corner: TR-UC08-C.
- Keep the IR path clear — The 850 nm IR reaches 100 m. Branches, eaves, walls or fence wire close to the lens reflect it and wash the night picture white, especially at the 106.6° wide end. Trim plants in front of the camera.
- Weather, cable and surge — The body is IP67, but the tail cable (RJ45, Ø5.5 mm power, audio, alarm and RS485 wires) must sit in a junction box. Surge protection is 6 KV; on poles and long outdoor runs add a surge protector and a proper earth.
- Backlight and vehicle lights — 140 dB WDR and HLC handle bright doorways and headlights, but do not aim straight into the rising or setting sun. For gates with cars, aim slightly across the lane rather than head-on.
AHDZK or AHDX4K: what each end of the zoom sees
Both models use the same 4 MP sensor and both zoom 4X; they cover different parts of the range. The AHDZK at 2.8 mm covers 26.8 m of width at 10 m, the AHDX4K at 32 mm only 2.7 m, but at 30 m the AHDX4K tele still puts about 336 pixels on each meter versus about 33 for the AHDZK wide end.
| AHDZK · 2.8 mm | AHDZK · 12 mm | AHDX4K · 8 mm | AHDX4K · 32 mm | |
|---|---|---|---|---|
| Horizontal view angle | 106.6° | 51.3° | 42.6° | 15.2° |
| Width covered at 10 m | 26.8 m | 9.6 m | 7.8 m | 2.7 m |
| Width covered at 30 m | 80.5 m | 28.8 m | 23.4 m | 8.0 m |
| Pixels per meter at 30 m | 33 | 93 | 115 | 336 |
| Identify a stranger's face up to | 6.8 m | 16.6 m | 12.4 m | 49.7 m |
| Recognize someone you know up to | 13.6 m | 33.2 m | 24.8 m | 99.3 m |
| Detect that something is there up to | 68.0 m | 166.2 m | 124.1 m | 496.6 m |
- Pick the AHDZK for yards, car parks and building fronts within about 30 m: at 2.8 mm it covers 26.8 m of width from 10 m away, and zooming to 12 mm identifies faces at 16.6 m.
- Pick the AHDX4K for gates, roads and fence lines 30–100 m away: at 32 mm it recognizes people at 99.3 m, which also matches the 100 m IR reach at night.
- Zoom is a trade-off, not a free gain: every step toward tele narrows the width. A common layout is an AHDZK for the overview and an AHDX4K aimed at the one entrance or lane that matters.
Widths are calculated from the horizontal view angle (width = 2 × distance × tan(angle ÷ 2)); pixels per meter = 2688 ÷ width. Face and detection distances are the manufacturer's DORI figures, measured in daylight.

4MP LightHunter Zoom Bullet FAQ — IPC264EA-AHDZK/AHDX4K-I1
What is the difference between the AHDZK and AHDX4K versions?
Both are 4MP with 4X motorized zoom and P-iris. AHDZK uses a 2.8–12 mm F1.2 lens with a 106.6°–51.3° view, identifying at 6.8–16.6 m — for wide areas. AHDX4K uses an 8–32 mm F1.6 telephoto, identifying at 12.4–49.7 m for long approaches.
How good is it in difficult light?
WDR is 140 dB — stronger than the common 120 dB — for gates where harsh sun meets deep shade. The 1/1.8-inch LightHunter sensor rates 0.0003 lux color on the AHDZK variant, and Smart IR reaches up to 100 m at 850 nm for night work.
Does it do face recognition on the camera?
Yes — it supports up to 16 face libraries with up to 100,000 faces, plus metadata capture of human bodies, faces, motor vehicles and non-motor vehicles with attribute collection. The camera itself can flag listed persons without a dedicated analytics server.
What storage options does it support?
Edge storage on MicroSD up to 512 GB, plus network storage with ANR and NAS (NFS). ANR means the camera keeps recording to the card during a network outage and backfills the recorder afterwards, so you do not lose footage when links drop.
What frame rates and power does it need?
The main stream runs 4 MP (2688×1520) at up to 60 fps, with 1080P sub and D1 third streams also at 60 fps. It powers over PoE+, and the IP67, IK10-rated housing stands up to weather, impact and tampering on exposed mounts.
Can the IPC264EA-AHDX4K-I1 really see 496 m at night?
No. The 496.6 m figure is the DORI detect distance of the lens at 32 mm, which applies when the scene is lit. The built-in 850 nm IR reaches 100 m, so in total darkness plan on about 100 m, where the camera can still recognize people (99.3 m at tele). Beyond that you need site lighting such as floodlights; the 0.0005 Lux color sensitivity then helps a lot.
The picture is sharp by day but soft at night after zooming in. How do I set the zoom and focus correctly?
Infrared light focuses at a slightly different point than daylight, and the effect is strongest at the tele end. Set the zoom from the web interface (or EZStation/NVR), refocus, then check the image again after dark with IR on and refocus if needed; check the day image once more afterwards. Also clean the front glass and remove spider webs, because at night IR lights them up and the lens may focus on them instead of the scene.
Will the IPC264EA-AHDZK-I1 / AHDX4K-I1 work with a non-Uniview NVR or VMS?
For video, usually yes: it supports ONVIF Profile S, G, T and M plus RTSP, and API/SDK for integrators. Live view, recording and basic events work over ONVIF; face library management, face comparison results, people counting and remote zoom may be limited or missing on other brands. Tell us your NVR or VMS model and we will confirm before you order.
What can I connect to the alarm, audio and RS485 wires of the IPC264EA?
The camera has 3 alarm inputs and 2 alarm outputs: inputs take dry contacts such as a door contact, PIR or beam detector, and outputs can trigger a siren, strobe or gate relay through an external relay sized for the load. There are 2 audio inputs and 1 audio output for an external microphone or amplified speaker, besides the built-in 2 mics and speaker. The RS485 port is listed; tell us what device you plan to connect to it so we can confirm support.
How much network bandwidth does the IPC264EA use, and do I need a gigabit switch?
The main stream runs from 128 Kbps up to 16 Mbps, so one camera never fills a 100 Mbps link on its own; the camera port itself is gigabit. The uplink to the NVR is where it matters: 10 cameras at the 16 Mbps maximum add up to 160 Mbps, which needs a gigabit uplink. For remote viewing on UNV-Link over mobile data, use the 1080P or D1 sub stream instead of the main stream.
