The Uniarch IPC-B314-ADZK is a 4MP bullet 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 50 m. It 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.
Long driveways & fence linesThe 2.8–12 mm motorized zoom can be tuned remotely after mounting — narrow the view to reach further down a driveway without re-aiming the bracket.
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.
Shops & storefrontsThe built-in mic picks up what is said at the counter, and MicroSD edge storage keeps a local backup even where an NVR is also recording.
Quick retrofits & pole installsOne PoE cable does power + video — no electrician needed on site, quick to install and reframe later thanks to the motorized zoom.
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
- Vandal-resistant IK rating — this model's datasheet lists no IK protection rating (IP67 dust/water rating only)
- Alarm in/out wiring for sirens or sensors

IR MODE
Invisible infrared — discreet black & white night vision
Smart IR up to 50 m (164.0 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.

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-B314-ADZK from its official datasheet: 4 MP, 2.8–12 mm motorized varifocal lens, faces identifiable up to 27.0 m, 50 m Smart IR, 120 dB WDR, PoE at max. 9.6 W.
Who it is for
- Long driveways, car parks and site entrances — At 12 mm it identifies a face up to 27.0 m and recognizes a known person up to 54.0 m, so one camera can watch a gate from across a yard.
- Installers who want one stock item for many distances — The motorized 2.8–12 mm lens covers 102.8° down to 35.8°, set from the browser after mounting, so the same camera fits a shop floor or a 25 m gate.
- Perimeters with human-based alarms — Cross line and intrusion are both based on human body detection, plus Ultra motion detection for people and vehicles, with invisible 850 nm IR up to 50 m at night.
- Shop fronts with mixed light — 120 dB true WDR and area white balance handle a bright street and a shaded interior in one frame; the built-in mic and MicroSD up to 512 GB add sound and a local copy.
Where and how to install
- Height and angle — Mount at about 2.5–3.5 m with a shallow downward tilt. When you zoom to the tele end, aim farther away rather than steeper down, or the frame shows the top of heads.
- Set the zoom with a test walk — Fix the bracket roughly, then zoom from the web interface or the Uniarch client while someone stands at the spot where faces matter. Zoom in until the face fills enough of the frame (about 2.25 m of identify distance per millimeter, up to 27.0 m at 12 mm), then check again after dark with the IR on.
- Keep IR from bouncing back — Do not mount tight under eaves or next to a wall, gutter or pole that sits inside the picture: the IR reflects back and turns the night image white. Keep branches and cobwebs away from the front glass.
- Weather, cable joint and surge — The body is IP67, but the RJ45 and 12 V tail is not: put it in the TR-JB05-A-IN junction box (wiring from behind) and seal the entry with the TR-A01-IN gland. Surge protection is 4 kV; on poles or long outdoor runs add a surge protector and earthing.
- Brackets — Pole: TR-UP06-B-IN, or TR-UP06-C-IN-V2 when the junction box is used; outside building corners: TR-UC08-C-V2. At 0.51 kg with a metal body, fix it to solid masonry or a firm pole so the zoomed-in picture does not shake in wind.
- Power and cable — It draws up to 9.6 W, much more than a fixed-lens camera, so check the PoE budget of the switch (IEEE 802.3af). Use Cat5e or Cat6 copper up to 100 m, or a 12 V DC adapter with a Ø5.5 mm plug.
2.8–12 mm motorized zoom: wide end or tele end
At the wide end it sees 102.8° and covers about 25.1 m of width at 10 m with about 102 pixels per meter. Zoomed to 12 mm the view narrows to 35.8° (about 6.5 m wide at 10 m) and detail rises to about 396 px/m, so faces are identifiable to 27.0 m instead of 6.3 m. From the DORI figures, the identify distance is about 2.25 m for every millimeter of focal length, half again as far as the 2 MP IPC-B312-ADZK (1.5 m per mm).
| Wide · 2.8 mm | Tele · 12 mm | |
|---|---|---|
| Horizontal view angle | 102.8° | 35.8° |
| Width covered at 5 m | 12.5 m | 3.2 m |
| Width covered at 10 m | 25.1 m | 6.5 m |
| Pixels per meter at 10 m | 102 px/m | 396 px/m |
| Identify a stranger's face up to | 6.3 m | 27.0 m |
| Recognize someone you know up to | 12.6 m | 54.0 m |
| Observe what is happening up to | 25.2 m | 108.0 m |
| Detect that something is there up to | 63.0 m | 270.0 m |
- Stay near the wide end for a shop floor, yard or car park seen from close: at 2.8 mm it covers 12.5 m of width from 5 m and still identifies faces to 6.3 m.
- For faces at a gate, divide the distance by 2.25 to get the focal length: a gate 15 m away needs about 6.7 mm, one 20 m away about 8.9 mm.
- At night the IR reaches 50 m, so the tele-end recognize, observe and detect figures (54.0 m, 108.0 m, 270.0 m) apply after dark only where there is other lighting.
Widths are calculated from the horizontal view angle (width = 2 × distance × tan(angle ÷ 2)); pixels per meter = horizontal pixels ÷ width at 10 m; face distances are the manufacturer's DORI figures at each end of the zoom. Settings between the two ends give values in between.

4MP Varifocal Bullet Camera FAQ — IPC-B314-ADZK
How far can the IPC-B314-ADZK see at night?
Its 850 nm smart IR reaches up to 50 m in complete darkness with auto or manual control. The light is invisible to the eye, so monitoring stays discreet, and Smart IR balances intensity so people close to the lens are not overexposed while the far end stays lit.
How far can it recognize a person with the motorized zoom?
The motorized 2.8–12 mm lens is set remotely after mounting. Wide at 2.8 mm it covers 102.8° with DORI detect at 63 m; zoomed to 12 mm it detects at 270 m, recognizes at 54 m and identifies at 27 m — strong reach for perimeters and long driveways.
Which intelligent alarms does it offer?
Cross line and intrusion detection run on human body detection, so perimeter alarms trigger on people instead of animals or moving shadows. Ultra motion detection and audio detection add broader coverage, and up to 8 ROI areas let you prioritize image quality where it matters.
Does it keep recording when the connection to the NVR fails?
Yes — MicroSD edge storage keeps writing 4MP footage locally during outages, and the built-in microphone captures audio with it. Encoding in Ultra 265 or H.265 at a configurable 128–6144 Kbps stretches how many days fit on the card.
How is it powered and can it face harsh weather and backlight?
PoE carries power and 4MP/25 fps video on one cable, simplifying pole installs. The housing is IP67 rated against dust and driving rain, and true 120 dB WDR with HLC, BLC and digital defog keeps subjects readable against sunlit gates and vehicle headlights.
IPC-B314-ADZK or the 2 MP IPC-B312-ADZK: which should I buy?
Both share the 2.8–12 mm motorized lens, 50 m IR, 9.6 W maximum power and the same body and brackets. The B314 records 4 MP and identifies faces to 27.0 m at 12 mm against 18 m for the B312, and to 6.3 m at the wide end against 4.2 m. The B312 is wider at 2.8 mm (111.0° against 102.8°) and streams 1080P at up to 30 fps. Choose the B314 when faces or details at a distance matter, the B312 for general overview on a tighter budget.
Which zoom setting should I use on the IPC-B314-ADZK for a gate 20 m away?
Around 9 mm. The datasheet identify distance grows from 6.3 m at 2.8 mm to 27.0 m at 12 mm, about 2.25 m per millimeter, so 20 m ÷ 2.25 ≈ 8.9 mm. The view at that setting is narrow, so the gate should fill most of the frame; if you also need the yard, add a second camera at the wide end. At night the 50 m IR covers a 20 m gate.
Will a third-party NVR record the IPC-B314-ADZK at 4 MP and control its zoom?
Recording usually works: the camera supports ONVIF Profile S, G and T and RTSP, and the NVR must accept 4 MP (2560 × 1440) and H.265 per channel. Zoom control over ONVIF varies by NVR brand and firmware, so set the zoom once from the camera's web interface or the Uniarch client during installation. Note the sub stream goes up to D1 (720 × 576), which is what most NVRs use for multi-screen and phone viewing. Tell us your NVR model and we will confirm before you order.
Can a small 4-port PoE switch run four IPC-B314-ADZK cameras?
Yes if its budget covers 4 × 9.6 W = 38.4 W at the datasheet maximum; the Uniarch SW-2106-LP with 4 PoE ports and 60 W does. Each port needs IEEE 802.3af, which gives up to 15.4 W at the switch. Check budgets more carefully on 8-port 60 W switches: they run only 6 of these cameras at full load.
How much storage does the IPC-B314-ADZK need at 4 MP?
Assuming 4096 Kbps for 4 MP with H.265 and continuous recording, about 44.2 GB per day: about 11.6 days on the maximum 512 GB MicroSD card or about 1.33 TB of NVR disk per camera for 30 days. At the 6144 Kbps maximum it is about 66.4 GB per day (7.7 days on 512 GB, about 2 TB for 30 days). Recording only on intrusion or cross line events cuts this sharply on quiet sites.
