A bi-spectrum radiometric thermal AI camera, new from Hanwha Vision, is for use in perimeter protection and traffic monitoring, among others.
The TNM-C3620TDR/C3622TDR cameras serve as compact indoor models and feature QVGA resolution on the thermal lens and 2MP on the visible sensor, while the TNM-C4940TDR/C4942TDR outdoor models combine VGA thermal and 4K video. The range is designed to deliver images in all lighting scenarios, with AI-powered analytics for object detection, and temperature monitoring between minus 20 degrees C and 130 degrees C.
With the outdoor models supporting AI on thermal and visible sensors, they can not only detect objects in difficult lighting, such as darkness, fog or rain, but also alert operators to potential intrusion, loitering or other suspicious behaviours. Meanwhile the compact indoor models feature AI on the visible channel.
The product firm adds that false alarms triggered by irrelevant motion, for example wildlife or shadows, are reduced, and meaning operators focus only on genuine events. Intelligent video analytics also include enter-exit monitoring and virtual line-crossing detection.
Temperature monitoring
The bi-spectrum radiometric thermal AI cameras offer temperature measurements between minus 20 degrees C and 130 degrees C, for industrial applications. By providing data on temperature changes, the cameras can alert operators to potential issues such as overheating parts or equipment failure, enabling proactive maintenance. Operators can toggle between eight colour palettes on the thermal channel, to review any temperature changes and enhance the visibility of a scene.
Perimeter protection
In particular, the outdoor models are the manufacturer says suited to perimeter protection and can alert operators to potential boundary breaches. The thermal lens can identify potential perimeter breaches across sites by detecting body heat signature, while the visual lens identifies and classifies objects. The cameras can also be used for traffic monitoring — alerting to stopped traffic that may signal a road accident or congestion. The cameras enable a high degree of accuracy and fewer false alarms.
The TNM-C3622TDR (indoor model) and TNM-C4942TDR (outdoor model) operate at eight frames per second (8fps) on the thermal sensor and therefore are excluded from the Wassenaar Arrangement, an export control regime that governs sensitive goods including cameras with frame rates over 9fps.
