The Uniview TIC2621SR-F3-4F4AC-VD is a 4MP dual-spectrum thermal network bullet camera that streams a thermal image and a 4MP optical image from a single IP address for side-by-side or picture-in-picture comparison. Its thermal channel is fully radiometric — it reads absolute temperature across −20 °C to +150 °C, tracks cold/hot spots, and raises an alarm with the temperature value overlaid on the snapshot, alongside dedicated fire-point and smoking detection. The 4MP optical channel (4 mm, up to 50 m IR range) gives full-resolution visual verification, while smart intrusion prevention (line crossing, area enter/leave) runs on both channels at once.
Is this the right camera for you?
Plain-language guide for buyers and installers — based only on what this camera actually does.
Fire-risk warehouses & plantsDedicated fire-point detection flags up to 10 hot points, and the radiometric thermal channel can trigger an alarm the moment a stack or panel crosses a set temperature.
Perimeter & fence-line securityThermal imaging spots a person up to 126 m away or a vehicle up to 316 m away in total darkness, fog or glare — then the optical channel confirms who or what it is.
Electrical & mechanical roomsCold & hot spot tracking highlights an overheating breaker or bearing before it fails, with the actual temperature value stamped on the alarm snapshot.
Industrial site perimetersSmart intrusion prevention (line crossing, enter/leave area) runs on both the thermal and optical channels at once, so coverage does not drop at night.
Smoking / no-smoking area enforcementBuilt-in smoking detection flags cigarette heat signatures in the thermal frame and links to an alarm, no separate smoke sensor needed.
Control-room live comparisonPicture-in-picture mode overlays the optical view on the thermal view (or vice versa) in one stream, so operators do not need two separate video windows.
Not the right pick if you need…
- Wi-Fi — this is a wired RJ45 camera
- Zoom on either channel — both lenses are fixed (4 mm optical / 3.2 mm thermal)
- Motorized pan-tilt-zoom control — mount is manual 3-axis adjustment only, not motorized
- A warm-light / full-color illuminator — this model uses infrared-only illumination on the optical channel (up to 50 m)
- Alarm in/out wiring beyond 2 in / 2 out — check channel count before planning sirens or sensors

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 | Optical · 4 mm · 89.9° | Thermal · 3.2 mm · 57.0° |
|---|---|---|
| 5 m16 ft | 10.0 m32.8 ft | 5.4 m17.8 ft |
| 10 m33 ft | 20.0 m65.5 ft | 10.9 m35.6 ft |

| 30 m98 ft | 59.9 m197 ft | 32.6 m107 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 TIC2621SR-F3-4F4AC-VD from its own specifications: 256 × 192 thermal (3.2 mm) plus 4 MP optical (4 mm) on one IP, -20 °C to +150 °C temperature alarms, fire and smoking detection, PoE 802.3af (max. 12 W).
Who it is for
- Warehouses, stockyards and recycling sites — Fire detection flags up to 10 fire points, and area temperature rules (up to 12) raise an alarm when a pile or pallet gets hotter than the limit you set.
- Perimeters, yards and fence lines at night — The thermal channel detects a person at 126 m and a vehicle at 316 m without any light; line-crossing and intrusion run on both channels, and the optical image shows who it is.
- Fuel, gas and chemical stores — Smoking detection in the thermal image links to an alarm, and the built-in speaker and red/blue warning lights tell the person to stop on the spot.
- Plant rooms and electrical areas — Hot-spot tracking shows the hottest point in the scene and alarms with the temperature on the snapshot — an early warning for overheating, used with its ±8 °C / ±8% accuracy in mind.
Where and how to install
- Aim both channels at the same area — The thermal view (57.0°) is narrower than the optical view (89.9°), so frame the area you need to protect in the thermal image first; the optical channel will then also cover it with margin.
- Height and distance — Mount at about 3–5 m on a wall or pole and tilt so the monitored stock or fence sits in the middle of the frame. For temperature alarms keep the target reasonably close: at 10 m the thermal channel has only about 24 pixels per meter.
- Keep sky, sun and known heat sources in check — Do not aim at the sun or bright sky, and avoid sunlit metal roofs that reflect heat. Exhausts, engines, lamps and kitchen vents look like fire points; cover them with fire shield areas before arming fire detection.
- Bracket and power — On poles use TR-UP06-C-IN, which is for the bullet junction box only, so order the matching junction box with it (ask us). The unit weighs 1.85 kg. Power from one 802.3af PoE port (max. 12 W) or DC 12 V on the Ø5.5 mm plug; the RJ45 is 10/100 Mbps, copper runs up to 100 m.
- Climate and protection — It works from -40 °C to 70 °C. The datasheet does not list an IP rating or surge rating, so for fully exposed outdoor sites confirm with us before ordering, seal the cable joints in a junction box and add an SPD and earthing on poles.
Thermal 3.2 mm and optical 4 mm: what each channel sees
The two channels do different jobs. The thermal channel sees heat, not light, so it finds people and vehicles far away in total darkness, but with 256 × 192 pixels it shows shapes, not faces. The optical channel has about 5.7× more pixels per meter at 10 m and a wider view, so it is the one that shows who or what triggered the alarm.
| Optical · 4 mm | Thermal · 3.2 mm | |
|---|---|---|
| Sensor resolution | 2688 × 1520 | 256 × 192 |
| Horizontal view angle | 89.9° | 57.0° |
| Width covered at 10 m | 20.0 m | 10.9 m |
| Width covered at 30 m | 59.9 m | 32.6 m |
| Pixels per meter at 10 m | 135 | 24 |
| Detect a person up to | 62.1 m | 126 m |
| Recognize: optical = known person, thermal = human vs. other target | 12.4 m | 32 m |
| Identify: optical = stranger's face, thermal = target type in detail | 6.2 m | 18 m |
| Detect a vehicle up to (thermal) | — | 316 m |
| Night operation | IR up to 50 m | No light needed |
- Use the thermal channel for the alarms (line crossing, intrusion, fire, temperature) on long or dark perimeters: it detects a person at 126 m.
- Use the optical channel to verify: faces only within 6.2 m and known people within 12.4 m, so add a fixed-lens camera at gates where identification matters.
- For temperature alarms on stock or equipment, keep the monitored object well inside the 10.9 m thermal width at 10 m, and closer for small objects.
Widths are calculated from the horizontal view angle (width = 2 × distance × tan(angle ÷ 2)); pixels per meter = horizontal pixels ÷ width at 10 m. Optical distances are the manufacturer's DORI figures; thermal distances are its DRI figures for a 1.8 × 0.5 m person and a 4 × 1.4 m vehicle.

Thermal Fire Detection Camera FAQ — TIC2621SR-F3-4F4AC-VD
Can it detect fire before flames spread?
Yes — the radiometric 256×192 vanadium-oxide sensor detects up to 10 fire points in the scene and links alarms automatically. It also detects smoking behaviour, which suits fuel depots, waste yards, substations and warehouses where early heat matters more than visible smoke.
Does it measure actual temperature?
It reads absolute temperature across a -20 to 150 °C range with area detection, cold and hot point tracking and alarm linkage; the measured value can be stamped onto the alarm picture. Sensor sensitivity is under 55 mK NETD, so small temperature differences show clearly.
How far can the thermal channel detect people and vehicles?
With the 3.2 mm F1.1 thermal lens it detects a vehicle (4×1.4 m target) at 316 m and a person (1.8×0.5 m) at 126 m in total darkness, no lighting needed. Recognition distances are 79 m for vehicles and 32 m for people.
What does the optical channel add?
A 1/1.8-inch 4MP sensor with 4 mm F1.6 lens and 89.9° horizontal view gives visual verification at 2688×1520, 30 fps, backed by 850 nm smart IR to 50 m, 120 dB WDR and 0.001 lux colour sensitivity — so operators confirm what the thermal alarm actually saw.
How do I power and connect it?
Either PoE over the network cable or DC 12 V locally — whichever suits the site. Video uses Ultra 265/H.265/H.264 at 128 Kbps–16 Mbps with triple streams, so the thermal and optical channels record together without heavy bandwidth.
What analytics does it run beyond fire detection?
Smart intrusion prevention on the optical channel — line crossing, intrusion, enter and leave area — with false alarm filtering and vehicle/non-motor classification, plus motion detection, tampering alarm and audio detection. The thermal image offers multiple palettes such as white hot and iron oxide red.
Can the TIC2621SR-F3-4F4AC-VD be used for body temperature or fever screening?
No. Body temperature screening is not listed, and the temperature accuracy is Max (±8 °C / ±8%), far too coarse to tell a fever from normal body temperature. It is made for threshold alarms on objects in the -20 °C to +150 °C range — stock piles, equipment, fire points — where a rise of tens of degrees is what matters.
How do I stop false fire alarms on the TIC2621SR-F3-4F4AC-VD from exhausts, vehicles or sunlight?
Use the fire shield areas listed in the datasheet to mask fixed hot sources such as chimneys, exhausts, engines, lamps or a heater, and aim the camera so the sun and sunlit metal surfaces are not in the thermal view. Where vehicles park inside the scene, shield their parking spots or rely on temperature-area rules with a threshold above engine temperature. Test for a few days, day and night, before linking alarms to sirens.
Will the TIC2621SR-F3-4F4AC-VD work with a non-Uniview NVR, and how many channels does it use?
Video usually works over ONVIF Profile S/G/T or RTSP. The thermal and optical images are two separate videos behind one IP address, so plan two recording channels on the NVR. Temperature readings, fire and smoking alarms, and the thermal palette settings are fully supported with Uniview NVRs and clients (EZStation, EZView, EZLive) and may not reach a third-party NVR. Tell us your NVR or VMS and we will confirm before you order.
Can the TIC2621SR-F3-4F4AC-VD warn intruders by itself with light and sound?
Yes. It has built-in red and blue warning lights and a built-in speaker for audio and light alarms, which can be linked to line-crossing, intrusion or smoking events. With the built-in mic, an operator can also talk to the person through the camera. For a louder siren, use one of the 2 alarm outputs to switch an external siren or strobe.
How long will the microSD card last on the TIC2621SR-F3-4F4AC-VD?
The maximum card is 256 GB. If the recorded streams add up to an assumed 6 Mbps in total (for example optical plus thermal), continuous recording writes about 64.8 GB per day, so a 256 GB card lasts about 4 days; at the 16 Mbps maximum bit rate it is about 172.8 GB per day, or about 1.5 days. For longer retention record to an NVR, or record on the card only on alarms.
