Need the PDF datasheet? Get it on WhatsApp →The Uniview IPC3238EA-AHDX4K(ZK)-I1 is an 8MP LightHunter WDR network dome camera built around a motorized 4X zoom lens, sold as two models: 2.8–12 mm (ZK) for wider-area coverage, or 8–32 mm (X4K) for longer-range detail. LightHunter low-light imaging and up to 140 dB optical WDR keep detail in dark and high-contrast scenes, backed by Smart IR to 40 m, a built-in mic and speaker, and MicroSD edge storage up to 512 GB. It powers over PoE+ (802.3at) or DC 12 V, and carries an IP67 + IK10 outdoor/vandal-resistant body rated −40 °C to 60 °C.
Is this the right camera for you?
Plain-language guide for buyers and installers — based only on what this camera actually does.
- Wi-Fi — this is a wired RJ45 camera
- Full-color night vision — this is IR-only, night video is black & white, not color
- Standard 802.3af PoE power — this model needs PoE+ (802.3at, up to 19 W) or DC 12 V; a plain 802.3af injector may not supply enough power
- One camera covering both close-wide and far-tele in a single continuous zoom — pick ZK (2.8–12mm) or X4K (8–32mm) at purchase; each is still adjustable on site, but only within its own range

Key Features
Complete list from the official datasheet.
Night Vision: Smart Infrared
Same IR illuminator on both zoom models — switchable Auto/Manual.
Invisible infrared — discreet black & white night vision
Smart IR up to 40 m (131.2 ft.) at 850 nm, Auto/Manual control. The camera watches without lighting up the scene. This model has a single IR illuminator only, no warm-light module, and the illumination distance is the same on both ZK and X4K.
How far can it see? (DORI)
DORI (EN 62676-4) is the industry standard for what a camera can do at distance. Both models are motorized zoom lenses, so each capability spans a range from the widest zoom setting to full telephoto — switch the model buttons above to compare ZK and X4K.
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 | ZK · 102.5° | 15.3° tele |
|---|---|---|
| 5 m16 ft | 12.5 m40.9 ft | 1.3 m4.4 ft |
| 10 m33 ft | 24.9 m81.8 ft | 2.7 m8.8 ft |
| 15 m49 ft | 37.4 m123 ft | 4.0 m13.2 ft |
| 20 m66 ft | 49.8 m164 ft | 5.4 m17.6 ft |
| 30 m98 ft | 74.8 m245 ft | 8.1 m26.4 ft |
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 IPC3238EA-AHDX4K(ZK)-I1 from its own specifications: 8 MP at 60 fps, motorized 4X zoom (2.8–12 mm ZK or 8–32 mm X4K), 140 dB WDR, 40 m IR, PoE+ (802.3at), IP67/IK10.
Who it is for
- Integrators on commercial projects — The motorized zoom is set after mounting, so one stock model covers many different spots; ONVIF Profile S/G/T/M, API and SDK make it fit Uniview or third-party recorders and VMS.
- Shops, banks and building lobbies — 140 dB optical WDR handles bright glass doors and windows behind people; the ZK version covers a whole shop floor at 2.8 mm, and on-camera face comparison (up to 16 libraries, 100,000 faces) flags known or unknown visitors.
- Car parks, gates and vehicle lanes — The X4K version (8–32 mm) identifies a face at 24.0–64.4 m by the manufacturer's DORI figures and captures motor vehicle and non-motor vehicle attributes for later search.
- Malls, stations and public areas — People flow counting and crowd density monitoring run on the camera, and the IK10 body resists hits in places within reach of the public.
- Cold, hot or remote outdoor sites — Rated −40 °C to 60 °C with a built-in heater and 6 kV surge protection; MicroSD up to 512 GB and ANR keep recording if the link to the NVR drops.
Where and how to install
- Height and aim — Indoors and at doors, mount at about 2.5–3.5 m with a shallow tilt so faces, not the tops of heads, fill the frame. For the X4K covering a far gate or lane, a higher mount is fine because the target is tens of meters away and the tilt stays shallow.
- Brackets for each surface — Wall: TR-WM04-IN, or TR-JB07/WM04-B-IN when the cable comes out of the wall behind the bracket. Pole: TR-UP06-IN with the wall bracket; building corner: TR-UC08-C. Suspended ceiling: TR-FM152-A-IN in-ceiling bracket; surface ceiling with a junction box: TR-JB04-C-IN.
- Set the zoom after mounting — Fix the dome first, then zoom and refocus with the motorized lens to frame the exact door, till or lane. Check focus again after dark: under IR the picture changes, so confirm the frame is still sharp at night before you close the job.
- Avoid IR glare — The 850 nm IR reaches 40 m. Keep eaves, walls and nearby poles out of the lower part of the picture, or they reflect IR back and the night image turns white and flat. Keep the dome cover clean and fit the protective film only after installation is finished.
- Power, cable and weather — Use an 802.3at (PoE+) port: the camera draws up to 19 W, more than a plain 802.3af port guarantees. Keep each Cat5e/Cat6 run within 100 m, seal cable entry with the TR-A01-IN NPT 3/4" gland or a junction box, and on poles or long outdoor runs add a surge protector and earthing on top of the built-in 6 kV protection.
- Backlight and wiring extras — 140 dB WDR copes with glass entrances, but do not aim straight at the low sun or into oncoming headlights. If you need a siren, door contact or external microphone, use the alarm I/O (3/2), audio I/O or RS485 inside the junction box rather than leaving tails exposed.
ZK (2.8–12 mm) or X4K (8–32 mm): what you actually see
Same 8 MP sensor, two zoom ranges. The ZK runs from very wide (24.9 m of width at 10 m) to medium; the X4K starts where the ZK ends and goes about 3× narrower. At its 32 mm end the X4K puts about 1429 pixels on every meter at 10 m, versus about 154 for the ZK at 2.8 mm.
| ZK · 2.8 mm (wide) | ZK · 12 mm (tele) | X4K · 8 mm (wide) | X4K · 32 mm (tele) | |
|---|---|---|---|---|
| Horizontal view angle | 102.5° | 48.5° | 42° | 15.3° |
| Width covered at 5 m | 12.5 m | 4.5 m | 3.8 m | 1.3 m |
| Width covered at 10 m | 24.9 m | 9.0 m | 7.7 m | 2.7 m |
| Pixels per meter at 10 m | ≈154 | ≈426 | ≈500 | ≈1429 |
| Identify a stranger's face up to | 10.8 m | 18.0 m | 24.0 m | 64.4 m |
| Recognize someone you know up to | 21.6 m | 36.0 m | 48.1 m | 128.9 m |
| Detect that something is there up to | 108.0 m | 180.0 m | 240.3 m | 644.4 m |
- Pick ZK for shop floors, lobbies, entrances and small yards: at 2.8 mm it covers 12.5 m of width from 5 m away, and zoomed to 12 mm it still identifies faces up to 18.0 m.
- Pick X4K for gates, vehicle lanes and long fence lines 25–60 m away: the manufacturer's identify distance is 24.0 m at 8 mm and 64.4 m at 32 mm.
- The two ranges almost meet (ZK at 12 mm is 48.5°, X4K at 8 mm is 42°). If a spot needs both overview and far detail, use one of each rather than a single camera.
Widths are calculated from the horizontal view angle (width = 2 × distance × tan(angle ÷ 2)); pixels per meter = 3840 ÷ width at 10 m; face distances are the manufacturer's DORI figures.
