The high resolution TPV-SW-20 / 35, night-vision, thermal camera from TBT is now available through the Security Buying Group. The camera’s thermal imaging resolution of 720 x 576 pixels out-performs most other thermal camera’s currently available in the security industry, successfully detecting people at night from over 800m away.

The thermal camera is designed for medium to long-range perimeter surveillance applications and offers extensive detection and recognition distances. Using its 35mm lens option, with a field of view 15.6°, it will detect people and vehicles at up to 803m and 2539m respectively, identifying them at 97m or 285m. The 20mm lens options give a shorter, but wider field of view at 27°. This lens option will detect people and vehicles at up to 459m and 1348m respectively, identifying them at 97m or 285m.

The night-vision camera’s thermal imaging video stream is produced using TBT’s unique, micro bolometer thermal sensor. It has 720 x 576 pixels Clear Video Resolution, a Noise Equivalent Temperature Difference (NETD) of less than 40mk and a Pixel Pitch of 25µm. TBT’s medium resolution, combined video and thermal imaging, night-vision camera with 320 x 240 pixels thermal resolution, has already been successfully launched by the Security Buying Group.
