Overview
The outdoor bullet TB9330-E and TB9331-E thermal camera provides a 360x240 or
720x480 resolution. The camera comes with a range of lenses with the 8.8mm (63.4°),
19mm (32°), 35mm (22°), 50mm (15.5° horizontal) horizontal elds of view. A lens with a
shorter focal length can cover a wide eld of view, while a lens with a longer focal length
can be used for targets at a greater distance. The camera enables easy detection of
human activities regardless of lighting conditions, whether in pitch dark or extremely bright
environments.
Compared to optical lens cameras, thermal cameras allow easier detection of people in
a wide surveillance area. When an optical camera’s eld of view is obscured by mist or
smoke, it is often very difcult for users to discern the presence of humans. The thermal
imaging of the TB series cameras allows you to detect targets by seeing through light
snow, dust, smoke, fog, or haze.
Coming in a weather proof housing with PoE power supply, the camera is suitable for video
surveillance as a perimeter protection. The capability of unobstrusive motion detection
in total darkness enables the camera for very early detection of an intruder. For thermal
cameras, false alarms no longer occur due to the effects of elements, such as swaying
vegetation, effects of artificial interferences such as fast light changes or backlights.
Humans wearing camuage, hiding in a bush or deep shadows are all likely to be detected
by thermal cameras, while the optical lens cameras cannot.
