Need the PDF datasheet? Get it on WhatsApp →The Uniview TIC3612SA is a thermal & optical bi-spectrum dome camera built around a 1/2.8" colour sensor paired with an uncooled 256×192 vanadium-oxide thermal core, streaming both channels from one IP address. The thermal channel reads absolute temperature (±8°C or ±8% accuracy) for fire and hot-spot alarms even in total darkness, smoke or glare, while the optical channel delivers 4MP colour video with smog recognition to confirm what the thermal channel sees. This page covers three lens options that share the same body: F2 (2.1mm thermal), F3 (3.0mm) and F7 (7.0mm) — pick the shortest for wide near-field coverage or the longest for long perimeter reach.
Is this the right camera for you?
Plain-language guide for buyers and installers — based only on what this camera actually does.
- Motorized PTZ / zoom — this is a fixed-lens turret; pick your thermal focal length (F2/F3/F7) at purchase
- Wi-Fi — this is a wired RJ45 camera
- 8MP/4K optical video — the optical channel tops out at 4MP (2688×1520)
- Battery or solar operation — needs PoE (802.3af) or DC12V wired power
- Coverage well beyond ~140 m — step up to a longer thermal lens or a PTZ thermal camera instead

Key Features
Complete list from the official datasheet.
Two channels, one camera
Thermal and optical run at the same time, from the same IP address — numbers below follow the lens selected above.
Radiometric temperature reading, day or night
256×192 vanadium-oxide sensor (NETD <50mK) reads absolute temperature at ±8°C or ±8% accuracy across two selectable ranges (-20 to 150°C / 100 to 550°C), tracking hot & cold spots automatically. At this lens, it flags a person at 21 m and a vehicle at 42 m; a 0.1×0.1 m fire or hot-spot event is caught at 9 m / 3.5 m.
4MP full-colour video with smog recognition
1/2.8" CMOS records true-colour 2688×1520 video at up to 30fps with 120dB WDR, and its smog recognition helps reconfirm a thermal fire alert. Picture-in-picture overlays both views on one live feed. At this lens, optical DORI identify range is 5.9 m (19.2 ft.), recognize 11.7 m (38.4 ft.).
How far can the optical channel see? (DORI)
DORI (EN 62676-4) is the industry standard for what a camera can do at distance — these figures are for the optical (visible-light) channel only; the thermal channel's detection range is shown in the next section. Switch the lens buttons above to compare.
Thermal detection & recognition range (Johnson's Criteria)
Theoretical maximum ranges for the thermal channel, calculated per Johnson's Criteria for a 4.0×1.4 m vehicle and a 1.8×0.5 m person — one row per lens on this page. Real-world smart-alarm trigger distances are the smaller, conservative figures shown in the stat bar and channel cards above.
| Lens | Detect (vehicle) | Detect (person) | Recognize (vehicle) | Recognize (person) | Identify (vehicle) | Identify (person) |
|---|---|---|---|---|---|---|
| 2.1 mm (F2) | 207 m | 83 m | 52 m | 21 m | 30 m | 12 m |
| 3.0 mm (F3) | 296 m | 119 m | 74 m | 30 m | 49 m | 17 m |
| 7.0 mm (F7) | 690 m | 277 m | 173 m | 69 m | 99 m | 40 m |
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 | F2 · 108.5° | F7 · 25.2° |
|---|---|---|
| 5 m16 ft | 13.9 m45.6 ft | 2.2 m7.3 ft |
| 10 m33 ft | 27.8 m91.1 ft | 4.5 m14.7 ft |
| 15 m49 ft | 41.7 m137 ft | 6.7 m22.0 ft |
| 20 m66 ft | 55.6 m182 ft | 8.9 m29.3 ft |
| 30 m98 ft | 83.3 m273 ft | 13.4 m44.0 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 TIC3612SA-F2/F3/F7-4F#AC-I1 from the official datasheets: 256 × 192 thermal channel with 2.1, 3.0 or 7.0 mm lens, 4 MP optical channel, fire and temperature alarms, compact IP67 dome, PoE 802.3af.
Who it is for
- Equipment rooms, battery and cable areas — The F2 version sees 88.8° wide in thermal, which suits a room or a row of cabinets seen from close. Temperature alarms (-20 to 150 °C or 100 to 550 °C, ±8 °C or ±8%) flag a cabinet, battery string or cable tray that runs hotter than normal.
- Warehouses and fire-risk storage — Thermal fire detection catches a 0.1 × 0.1 m fire at 9 m (F2), 13 m (F3) or 29 m (F7), and the optical smog recognition helps confirm it. The dome shape fits under canopies and loading-bay roofs.
- Building perimeters and unlit yards — Intrusion and crossline rules run on both channels with human/vehicle classification; in total darkness the thermal channel detects a person at 21 m (F2), 30 m (F3) or 70 m (F7).
- Installers who want one small unit and one cable — Φ129 × 114 mm and about 0.72 kg, PoE 802.3af (max 12 W), two video channels under one IP address, ONVIF Profile S/G/T, 2/2 alarm I/O and a built-in mic and speaker.
Where and how to install
- Distance decides the version — Temperature readings need the target close: 3.5 m (F2), 8 m (F3), 20 m (F7) for a 0.1 × 0.1 m spot. Fire is detected at 9/13/29 m and a person at 21/30/70 m. Choose the version by the farthest thing you must measure, not only by what you want to see.
- Aim with the thermal frame — The thermal view is narrower than the optical view (F2: 88.8° vs 108.5°; F7: 25.2° vs 49.1°). Adjust the dome while watching the thermal stream and draw alarm zones there; what is only at the edge of the optical image is not covered by thermal alarms.
- No glass, no hot clutter — Do not mount it behind a window or inside a glass enclosure: glass blocks thermal. Keep lamps, heaters, air-conditioner units, engine exhausts and sun-lit metal out of the fire and temperature zones, or exclude them with the fire shield area.
- Brackets for each surface — Ceiling or soffit: direct mount, with junction box TR-JB03-H-IN when the cable comes from behind. Wall: TR-WM03-B-IN, or TR-JB07/WM03-F-IN with a back hole for the cable. Corner: TR-UC08-C. Pole: TR-UP06-IN. Mount at about 2.5–3.5 m for doors and yards.
- Power, cable and weather — PoE 802.3af or DC 12 V (Ø5.5 mm plug); reserve 12 W per camera on the switch and keep each Cat5e/Cat6 run within 100 m. It is IP67, works from -40 °C to 70 °C and has 6 kV surge protection; seal the cable entry with the TR-A01-IN gland and add an external surge protector on exposed poles.
F2, F3 or F7: what each thermal lens covers
Same dome, same 256 × 192 thermal sensor; only the lens pair changes. The F2 covers 19.6 m of width at 10 m but detects a person only to 21 m; the F7 reaches 70 m but is 4.5 m wide at 10 m. Thermal shows heat: it finds people, vehicles, hot spots and fire in darkness, smoke or glare, but it cannot show faces, colors or plates and cannot see through glass. The optical channel does that, within its identify distance.
| F2 · 2.1 mm thermal / 2.6 mm optical | F3 · 3.0 mm thermal / 4.0 mm optical | F7 · 7.0 mm thermal / 6.0 mm optical | |
|---|---|---|---|
| Thermal horizontal view angle | 88.8° | 58.0° | 25.2° |
| Thermal width covered at 5 m | 9.8 m | 5.5 m | 2.2 m |
| Thermal width covered at 10 m | 19.6 m | 11.1 m | 4.5 m |
| Person detection (1.8 × 0.5 m) | 21 m | 30 m | 70 m |
| Vehicle detection (4 × 1.4 m) | 42 m | 60 m | 140 m |
| Fire detection (0.1 × 0.1 m fire) | 9 m | 13 m | 29 m |
| Temperature measurement (0.1 × 0.1 m target) | 3.5 m | 8 m | 20 m |
| Optical horizontal view angle | 108.5° | 74.9° | 49.1° |
| Optical: identify a face up to | 5.9 m | 9.0 m | 13.5 m |
| Optical IR distance | 30 m | 30 m | 30 m |
- Pick F2 for rooms, doorways and cabinet rows seen from close: 9.8 m of thermal width at 5 m; temperature readings only up to 3.5 m.
- Pick F3 for most yards and building sides: 11.1 m wide at 10 m, a person detected at 30 m and fire at 13 m.
- Pick F7 for a straight fence or a stack yard: a person at 70 m, fire at 29 m and temperature up to 20 m, but only 4.5 m wide at 10 m.
Widths are calculated from the thermal horizontal view angle (width = 2 × distance × tan(angle ÷ 2)). Detection, fire and temperature distances are the manufacturer's alarm values for the stated target sizes in good weather; heavy rain or dense fog shortens them.
