The IPC9312LFW-AF28-2X4 is a LightHunter dual-lens network PTZ camera pairing a fixed 2.8 mm, 1080P panorama channel (Channel 1, 102.4° horizontal field of view) with a 4× optical-zoom, 2.8-12 mm PTZ detail channel (Channel 2), outputting both streams from a single IP address. The fixed channel runs smart intrusion prevention — cross line, intrusion, enter-area and leave-area detection with human / non-motor-vehicle / vehicle classification and false-alarm filtering — and when a rule triggers, the PTZ channel automatically links, zooms in and tracks the target. LightHunter low-light processing (color at 0.002 lux on both channels), up to 120 dB WDR, IR to 50 m plus a 10 m warm light on the detail channel, dual built-in microphones with a high-power speaker for two-way audio, and an IP66 housing powered by DC 12 V or PoE+ (802.3at) round out the package.
Is this the right camera for you?
Plain-language guide for buyers and installers — based only on what this camera actually does.
Entrances & access pointsThe fixed channel covers the whole gate or lane at 102.4° while the PTZ channel zooms 4× for a closer look at faces and plates — one pole, two jobs.
Perimeter with auto-link trackingSmart intrusion prevention on the fixed channel — cross line, area enter/leave, with person/vehicle classification — automatically triggers the PTZ channel to zoom in and track the target.
Warehouse yards & loading docksOne overall view of the yard plus 256 presets and 16 patrols on the PTZ channel let a single camera watch gates, docks and stacking areas in sequence.
Low light & night operationLightHunter sensors hold color down to 0.002 lux on both channels; when it gets fully dark, 50 m IR and a 10 m warm light on the PTZ channel take over for full-color evidence.
On-site voice deterrenceBuilt-in dual microphones and a high-power speaker support two-way audio, so guards can talk down an intruder the moment the intrusion alarm fires — no separate horn needed.
Flexible wall or ceiling installBoth wall-mount and ceiling-mount forms ship with the unit; IP66 sealing and a -20 °C to 60 °C working range cover most eave, corridor and covered-yard mounting spots.
Not the right pick if you need…
- No zoom on the fixed panorama channel — it is locked at 2.8 mm. If you need to zoom into any part of the wide view (not only the linked target), a full multi-sensor panoramic model is a better fit.
- Only IP66 sealing and no IK-rated impact resistance is listed — not the choice for high-vandalism sites; pick an IK10-rated model instead.
- Pan range is 0° to 345° and tilt -10° to 100° — not a continuously rotating dome. If you need endless 360° pan, choose a different PTZ series.
- Detail-channel zoom tops out at 4× (2.8-12 mm) — for long-range (150 m+) identification tasks, a higher-zoom PTZ camera will serve better.

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 | AIL · 106.6° | 30.6° tele |
|---|---|---|
| 5 m16 ft | 13.4 m44.0 ft | 2.7 m9.0 ft |
| 10 m33 ft | 26.8 m88.0 ft | 5.5 m18.0 ft |

| 30 m98 ft | 80.5 m264 ft | 16.4 m53.9 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 IPC9312LFW-AF28-2X4 from its own datasheet: 2 MP fixed 2.8 mm panorama channel plus 2 MP 4x (2.8–12 mm) PTZ detail channel on one IP, linkage tracking, 50 m IR and 10 m warm light on the detail channel, PoE+ or DC 12 V (max. 16 W).
Who it is for
- Shops, offices and small businesses — One unit and one cable give a constant 102.4° overview of the entrance plus a 4x close-up that follows whoever trips the intrusion rule, so nothing in the wide view is lost while the PTZ zooms.
- Homes and villas — Gates, driveways and gardens: the dual microphones and high-power speaker allow two-way talk from the UNV-Link app, and the 10 m warm light gives color video of a visitor close to the camera.
- Small yards, loading docks and car parks — The detail channel has 256 presets and 16 patrols, so between alarms it can visit gates and docks in turn while the fixed channel keeps watching the whole area.
- Installers who want a simple PoE+ job — Both channels come from a single IP address and one RJ45, powered by an IEEE 802.3at port (max. 16 W), and the web client offers 22 languages for handover.
Where and how to install
- Height and aim — Mount at about 3–4 m, looking along the path people and vehicles take toward the entrance. Faces are identifiable only up to 4.3 m on the fixed channel and up to 16.3 m with the detail channel fully zoomed, so do not mount it far from the door.
- Point the pan gap at the wall — The detail channel pans 0° to 345°, not endlessly, so 15° of the circle cannot be reached. On a wall mount, place that gap toward the wall behind the camera, where there is nothing to track.
- Wall, ceiling, pole or corner — It supports wall mount and ceiling mount. Listed accessories: TR-JB07-D-IN junction box with the TR-UP06-C-IN pole bracket for it, TR-UP06-B-IN pole bracket, TR-UC08-C corner bracket, TR-CM06-D hoisting bracket and the TR-A01-IN NPT 3/4" waterproof cable gland. Confirm which bracket set you need before ordering.
- Power and cable — Use an IEEE 802.3at (PoE+) port: the camera draws up to 16 W, more than the 15.4 W an 802.3af port supplies. Or use DC 12 V on the Ø5.5 mm plug. The network port is 10/100 Mbps; keep each copper run within 100 m and put the cable joint in the junction box.
- Weather and surge — The housing is IP66 and works from -20 °C to 60 °C, so it suits warm and temperate climates but not sites colder than -20 °C. Surge protection is 2 kV; on outdoor runs or poles add a PoE surge protector and earthing.
Panorama and detail channels: what each one sees
The panorama channel is fixed at 2.8 mm and always covers about 24.9 m of width at 10 m. The detail channel starts almost as wide (106.6°) and zooms to 12 mm (30.6°), where it puts about 351 pixels on each meter at 10 m instead of about 77, enough to identify a face up to 16.3 m.
| Panorama · 2.8 mm fixed | Detail · 2.8 mm (wide) | Detail · 12 mm (tele) | |
|---|---|---|---|
| Horizontal view angle | 102.4° | 106.6° | 30.6° |
| Width covered at 5 m | 12.4 m | 13.4 m | 2.7 m |
| Width covered at 10 m | 24.9 m | 26.8 m | 5.5 m |
| Width covered at 20 m | 49.7 m | 53.7 m | 10.9 m |
| Pixels per meter at 10 m | 77 px/m | 72 px/m | 351 px/m |
| Identify a stranger's face up to | 4.3 m | 4.3 m | 16.3 m |
| Recognize someone you know up to | 8.7 m | 8.7 m | 32.6 m |
| See what a person is doing up to | 17.4 m | 17.4 m | 65.2 m |
| Detect that something is there up to | 43.4 m | 43.4 m | 162.9 m |
| IR night distance | 10 m | 50 m | 50 m |
| Warm light (color at night) | N/A | 10 m | 10 m |
- Draw the intrusion or cross line rule on the panorama channel over the area people must cross; the detail channel then zooms in and tracks the target.
- For faces at a gate 10–15 m away, rely on the detail channel at the tele end: it identifies up to 16.3 m.
- At night the panorama channel's IR reaches only 10 m: light the area if detection must work farther out.
Widths are calculated from the horizontal view angle (width = 2 × distance × tan(angle ÷ 2)); pixels per meter = 1920 ÷ width; identify/recognize/observe/detect distances are the manufacturer's DORI figures (EN 62676-4) from the datasheet, per channel.

Dual-Lens Tracking PTZ FAQ — IPC9312LFW-AF28-2X4
How does the auto tracking work on this camera?
The fixed 2.8 mm lens watches a 102.4° wide scene. When its smart intrusion rules fire — cross line, intrusion, enter or leave area — the linked PTZ channel with 2.8–12 mm 4x optical zoom automatically follows the target, so you keep overview and close-up at the same time.
What resolution do the two channels record?
Both channels stream 1080P (1920×1080) at up to 25 fps, with dual streams per channel and Ultra 265/H.265 compression at 128 Kbps–16 Mbps. LightHunter low-light performance takes colour down to 0.002 lux on both lenses.
What are the night vision distances?
The panorama lens carries 10 m of 850 nm IR for the near field, while the detail PTZ lens reaches 50 m with IR and adds a 10 m warm light. Smart IR, digital defog and 2D/3D noise reduction are built in on top.
Does it support SD card recording?
Yes — MicroSD up to 512 GB at the edge, plus NAS (NFS) network storage and ANR, which backfills recordings to the recorder after a network dropout. Two-way audio with noise suppression is included for voice talk-down.
What about power and third-party NVR compatibility?
Power is PoE+ over a single cable, and the IP66-rated body mounts outdoors. Integration follows ONVIF Profile S, G and M plus API and SDK, so it registers on ONVIF-conformant NVRs and VMS platforms, with RTSP/RTMP streaming as fallback.
Will the IPC9312LFW-AF28-2X4 linkage tracking work at night beyond 10 m?
Only if there is some light. Tracking is triggered by the smart intrusion rules on the fixed panorama channel, and that channel's own IR reaches 10 m; the 50 m IR and 10 m warm light belong to the detail channel. In total darkness, keep the rule areas within about 10 m of the camera, or add street, yard or IR lighting so the panorama channel can still see targets farther out (LightHunter gives color down to 0.002 lux).
How many NVR channels and how much storage does the IPC9312LFW-AF28-2X4 use?
Plan it as two cameras: it has one IP address but two video channels, and an NVR normally counts each channel against its camera limit. At an assumed 4 Mbps per 1080P channel with continuous recording, both channels write about 86.4 GB per day, so a 512 GB microSD card holds about 5.9 days and 30 days on an NVR need about 2.6 TB. The bit rate can go up to 16 Mbps per stream, which would multiply that by four; Ultra 265 and event recording reduce it.
How close does a person need to be for the IPC9312LFW-AF28-2X4 to show a usable face?
On the fixed panorama channel, about 4.3 m to identify a stranger and 8.7 m to recognize someone you know. The detail channel at full 4x zoom identifies up to 16.3 m and recognizes up to 32.6 m, which is why the linkage zooms it onto the target. For number plates or faces much farther than about 16 m, a higher-zoom PTZ or a dedicated camera at the gate is the better choice.
Can I talk to visitors or warn intruders through the IPC9312LFW-AF28-2X4?
Yes, by live two-way audio: it has built-in dual microphones and a high-power speaker, used from the Uniview clients (EZStation, UNV-Link, UNV-Link Pro). The datasheet does not list pre-recorded voice alarms, strobe or alarm input/output terminals, so plan on a person speaking when the intrusion alert arrives. Mount it where wind and traffic noise are low, as the microphones pick up everything nearby.
Should I choose the IPC9312LFW-AF28-2X4 or a 4 MP + 4 MP model such as the IPC94144SR-X25-F40C?
Choose the IPC9312LFW-AF28-2X4 for entrances, shops and homes where targets are within about 16 m: it is light (1.03 kg), runs on one PoE+ port and adds warm light and two-way audio. Our range also lists the IPC94144SR-X25-F40C and IPC94144SFW-X25-F40C as 4 MP + 4 MP dual-lens PTZ models with 25x zoom for larger yards and longer distances; compare their power and night figures on their own pages, or send us your site layout.
