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 35 mm lens is able to detect vehicles at a distance of up to 4,472 metres and people at 1,750 metres, while the Wisenet TNO-3040T has a fixed 19 mm lens and detects vehicles at up to 2,428 metres and people at 950 metres.
The two new IK10/IP66-rated, vandal-resistant and weatherproof thermal cameras, which complement existing thermal models within the Wisenet T series, capture images at up to 320 x 240 resolution.
A temperature detection feature triggers an alert if there’s 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 further 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’s technology partner A.I Tech.
*Operating temperature of -40°C to +60°C.
*IP66, IK10 and NEMA4X rated for protection against water, dust and mechanical impact
*Digital Image Stabilisation with built-in Gyro sensors which comes into effect when a camera is disturbed by wind or vibrations (this delivers more stable images, while also compensating for roller shutter effects)
*A Hallway view feature enables end users to monitor tall and narrow spaces more effectively in 3:4 or 9:16 aspect ratios
*Support for H.265, H.264 and MJPEG compression formats, as well as WiseStream II (a complementary compression technology which improves bandwidth efficiency by up to 75% compared to current H.264 technology, when combined with H.265 compression)
*Micro SD/SDHC/SDXC slot which allows up to 256 GB of video or data to be stored at the edge should there be disruption to the network
*PoE which negates the need to install a power supply and reduces cabling requirements
Unlike traditional cameras which rely on light to see images, thermal cameras pick up heat signatures of objects and are unaffected by extreme conditions, such as complete darkness, harsh weather, bright lights, fog and smoke. They also offer an effective solution for applications where there are concerns about light pollution.
