The Uniarch IPC-T312-ADZK is a 2MP turret network camera with a motorized varifocal lens (2.8–12 mm, 4.3X zoom) that lets the field of view be adjusted remotely after installation — no re-mounting needed to reframe the shot. It combines 120 dB true WDR for strong-light scenes, ultra motion detection (human/vehicle classification), a built-in mic, and Smart IR night vision up to 30 m. The metal body is IP67 outdoor-rated, and powers over a single PoE cable or DC 12V, with a −30 °C to 60 °C working range.
Is this the right camera for you?
Plain-language guide for buyers and installers — based only on what this camera actually does.
Schools & transit stationsThe 2.8–12 mm motorized zoom can be tuned remotely after mounting — reframe the shot in a busy public area without climbing back up to the bracket.
Hallways & low ceilingsThe compact turret body mounts flush to a ceiling or wall and blends into the surroundings — less obtrusive than a bullet camera indoors.
Parking lots & vehicle gatesUltra motion detection tells people from vehicles, cutting false alerts from a busy lot down to the movement that actually matters.
Storefronts facing strong sunlight120 dB true WDR keeps both the bright doorway and the shaded interior visible in the same frame, instead of one washing out the other.
Warehouse & site perimetersIP67 body and −30 to 60 °C rating survive rain, dust and heat outdoors, day after day.
Sites needing local backupThe built-in mic picks up nearby audio, and MicroSD edge storage keeps a local backup even where an NVR is also recording.
Not the right pick if you need…
- Full-color night vision — this is IR-only, night video is black & white, not color
- Two-way talk — it has a built-in mic but no speaker
- Wi-Fi — this is a wired RJ45 camera
- A one-time fixed focal length choice at purchase — the zoom on this model is motorized and adjustable on site, not a pick-one-at-checkout fixed lens
- Alarm in/out wiring for sirens or sensors

IR MODE
Invisible infrared — discreet black & white night vision
Smart IR up to 30 m (98.4 ft.) at 850 nm. The camera watches without lighting up the scene — nothing shows it is recording. This model has a single IR illuminator only, no warm-light module.
How far can it see? (DORI)
DORI (EN 62676-4) is the industry standard for what a camera can do at distance. Because this model has a motorized 2.8–12 mm varifocal lens, each capability spans a range — from the widest zoom setting to full telephoto, not a single fixed number.

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 | 111.0° wide | 36.6° tele |
|---|---|---|
| 5 m16 ft | 14.6 m47.7 ft | 3.3 m10.9 ft |
| 10 m33 ft | 29.1 m95.5 ft | 6.6 m21.7 ft |

| 30 m98 ft | 87.3 m286 ft | 19.8 m65.1 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 Uniarch IPC-T312-ADZK from its official datasheet: 2 MP turret, 2.8–12 mm motorized varifocal lens (111.0° to 36.6°), Smart IR up to 30 m, 120 dB WDR, MicroSD up to 512 GB, PoE or 12 V DC (max. 7.5 W).
Who it is for
- Installers who do not know the exact distance before the job — One model covers everything from a 111.0° room view to a 36.6° gate view, so you carry one part number and set the framing on site from the browser or client.
- Car parks, gates and loading areas — Cross line, intrusion based on human body detection and ultra motion detection (human/vehicle) target real movement, and at 12 mm a face can be identified up to 18 m.
- Entrances facing bright daylight — 120 dB true WDR keeps a bright doorway and a dark interior readable in the same frame, with BLC and HLC as extra tools.
- Outdoor walls and covered walkways — The all-metal IP67 body works from −30 °C to 60 °C with 4 kV surge protection, and a MicroSD card up to 512 GB keeps a local copy.
Where and how to install
- Mount first, frame later — Mount at about 2.5–3.5 m (tilt 0° to 75°), point it roughly at the target, then set zoom and focus remotely. Zoom in until the area where faces matter is within the identify distance for that setting: 4.2 m at 2.8 mm up to 18 m at 12 mm.
- Plan night views within 30 m — Daylight detection reaches 180 m at 12 mm, but the IR only lights 30 m. At night, anything you need to see must be within 30 m or under its own lighting.
- Avoid IR reflection — Keep the turret clear of eaves, gutters and nearby walls that enter the picture, especially at the wide 111.0° setting; never film through glass at night.
- Junction box, cable and surge — The body is IP67 but the RJ45 and Ø5.5 mm DC tail are not: use the metal-turret junction box TR-JB03-H-IN-V2 or TR-JB03-J-IN, with the TR-A01-IN gland for conduit. Surge protection is 4 kV; add a PoE surge protector and earthing on poles and long outdoor runs.
- Brackets — Wall: TR-WM03-B-IN-V2 or TR-JB07/WM03-F-IN-V2 (with back hole); outside corner: TR-UC08-C-V2; pole: TR-UP06-C-IN-V2 together with the junction box; indoor high ceilings: TR-CM24-IN with the 200 mm TR-SE24-IN or 500 mm TR-SE24-A-IN pole.
Wide end or tele end: what you actually see
Any setting between these two columns is possible. At 2.8 mm it covers about 29.1 m of width at 10 m but only about 66 pixels per meter; at 12 mm the width at 10 m is about 6.6 m with about 290 pixels per meter, and every DORI distance is about 4.3× longer. At night the 30 m IR is the real limit, whatever the zoom.
| Wide · 2.8 mm | Tele · 12 mm | |
|---|---|---|
| Horizontal view angle | 111.0° | 36.6° |
| Width covered at 5 m | 14.6 m | 3.3 m |
| Width covered at 10 m | 29.1 m | 6.6 m |
| Pixels per meter at 10 m | ≈66 px/m | ≈290 px/m |
| Identify a stranger's face up to | 4.2 m | 18 m |
| Recognize someone you know up to | 8.4 m | 36 m |
| Observe what is happening up to | 16.8 m | 72.0 m |
| Detect that something is there up to | 42.0 m | 180 m |
- Near the wide end: rooms, lobbies and yards seen from close, 14.6 m of width at 5 m.
- Near the tele end: a gate, barrier or doorway 15–18 m away where faces must be identified.
- In between: a driveway or fence line where you want both some width and recognition at 10–20 m; check the live image at night before you leave the site.
Widths are calculated from the horizontal view angle (width = 2 × distance × tan(angle ÷ 2)); pixels per meter = horizontal pixels ÷ width at 10 m; distances are the manufacturer's DORI figures from the official datasheet.

2MP Varifocal Turret Camera FAQ — IPC-T312-ADZK
How far can the IPC-T312-ADZK see with the 2.8-12 mm lens?
At 2.8 mm it covers a wide 111° field and detects a person at 42 m; zoomed to 12 mm the view narrows to 36.6° but detection stretches to 180 m, recognition to 36 m and identification to 18 m. One camera can therefore cover both a yard and its far fence line.
Can I adjust the zoom after the camera is mounted?
Yes — the varifocal lens is motorized, so you set focal length and focus from the configuration interface instead of opening the housing on a ladder. That makes commissioning faster and lets you re-frame the scene later if the site layout changes.
How does it perform at night and in strong backlight?
Smart IR at 850 nm reaches 30 m with automatic black-and-white switching, and the F1.6 aperture keeps color down to 0.005 lux. True 120 dB WDR balances a bright gate against shaded interiors, while HLC tames headlights and digital defog helps in dust or haze.
What smart detection does it offer?
Cross-line and intrusion detection are based on human body detection, so perimeter rules trigger on people rather than animals or moving shadows. Ultra motion detection, standard motion detection, tampering alarm and audio detection round out the alert set for gates and yards.
How is it powered, and does it record locally?
PoE brings power and video over one network cable, simplifying pole and wall installs. The IP67 body withstands dust and rain, a built-in mic adds audio to recordings, and a MicroSD slot provides local storage so footage survives network outages.
What bandwidth should I budget per camera?
Main stream is 1080P at up to 30 fps; bit rate is adjustable from 128 to 6144 Kbps, so plan around your quality target. Ultra 265 and U-code compression cut the real-world average well below the peak, and dual streams keep mobile viewing light.
If I zoom the IPC-T312-ADZK to 12 mm, will it still see 18 m away at night?
Yes for 18 m, because that is inside the 30 m IR range; the datasheet's 18 m identify distance at 12 mm can be used day and night if the scene is clear. Beyond 30 m the IR does not light the scene, so the 36 m recognize and 72.0 m observe figures at 12 mm apply only in daylight or under site lighting. Night IR images are black and white.
Can a Hikvision, Dahua or other third-party NVR control the zoom on the IPC-T312-ADZK?
Video and recording will usually work: the camera supports ONVIF Profile S, G and T plus RTSP. Zoom and focus control, cross line, intrusion and ultra motion events are fully supported on Uniarch/Uniview recorders and may be partial or missing on other brands. The safe method is to set zoom and focus once in the camera's web page or the Uniarch client, then add it to the third-party NVR; tell us your NVR model and we will confirm before you order.
How many IPC-T312-ADZK cameras can a PoE switch power?
Plan on the full 7.5 W per camera, which is higher than fixed turrets because of the zoom motor and IR. Eight cameras need about 60 W, so an 8-port switch with a 60 W budget such as the Uniarch SW-2110-LP is at its limit; for 8 or more, the SW-2218-LP (150 W, 16 PoE ports) leaves margin, for example 16 cameras need about 120 W. Each camera fits within one IEEE 802.3af port, with Cat5e/Cat6 up to 100 m per run.
IPC-T312-ADZK or the 4 MP IPC-T314-ADZK: which should I choose?
Both are WDR varifocal IR turrets in the same family. This 2 MP model (1920 × 1080) is the budget option: smaller recordings and enough detail when you zoom in on a defined spot, such as a door at 12 mm with about 290 pixels per meter at 10 m. Choose the 4 MP IPC-T314-ADZK when you keep the lens wide to cover a big area and still need detail at the edges.
How do I mount the IPC-T312-ADZK on a pole or with the cable coming from behind?
Use one of the metal-turret junction boxes listed for this model, TR-JB03-H-IN-V2 or TR-JB03-J-IN, which support wiring from behind and give the RJ45 and DC joints a dry space. On a pole, add the TR-UP06-C-IN-V2 bracket, which is made for the junction box only. The camera weighs 0.66 kg, so use proper anchors on hollow walls and seal the conduit entry with the TR-A01-IN gland.
