Hanwha Techwin has strengthened its ‘affordable’ Wisenet QVGA resolution thermal camera range with the introduction of two medium distance models designed to help provide perimeter protection of large open sites.
The TNO-3050T with a fixed 35mm lens is listed as able to detect vehicles at a distance of up to 4,472m and people at 1,750m, whilst the Wisenet TNO-3040T has a fixed 19mm lens and detects vehicles at up to 2,428m and people at 950m. The two new IK10/IP66 rated vandal-resistant and weatherproof thermal cameras capture images at up to 320 x 240 resolution.
A temperature detection feature triggers an alert if there is a rapid, significant change in temperature, with operators able to define up to three ‘regions of interest’ within a camera’s field of view. The cameras are also equipped with a suite of video analytics which includes enter/exit, appear/disappear, direction, virtual line, loitering, shock and tamper detection. When operating in complete darkness, the effectiveness of the cameras is enhanced by audio analysis functionality, which recognises critical sounds such as gunshots, explosions, screams and broken glass.
The open platform cameras are also able to support third-party video analytics applications, such as the edge-based intruder detection application developed by Hanwha Techwin technology partner A.I Tech.
