Hanwha Vision has launched new high-performance bi-spectrum radiometric thermal AI cameras for various applications. The cameras provide clear images in all lighting conditions, accurate object detection, and temperature monitoring from -20°C to 130°C.
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 advanced VGA thermal and 4K video. The range is designed to deliver clear images in all lighting scenarios, with AI-powered analytics for accurate object detection, and temperature monitoring .
AI for greater accuracy
The outdoor models support AI on thermal and visible sensors, so they can not only detect objects in difficult lighting conditions, such as complete 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.
By ensuring a high degree of accuracy across the range, false alarms triggered by irrelevant motion, for example wildlife or shadows, are significantly reduced, improving operational efficiency and meaning operators focus only on genuine events. Intelligent video analytics also include enter/exit monitoring and virtual line-crossing detection.
Precise temperature monitoring
The bi-spectrum radiometric thermal AI cameras offer precise temperature measurements between -20°C and 130°C, making them ideal for industrial applications. By providing critical data on temperature changes, the cameras can alert operators to potential issues such as overheating parts or equipment failure, minimising downtime, enabling proactive maintenance, and enhancing operational efficiency and safety. Operators can toggle between eight colour palettes on the thermal channel, to easily review any temperature changes and enhance the visibility of a scene.
Perimeter protection and traffic management
In particular, the outdoor models are well 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.
Flexible options
The TNM-C3622TDR (indoor model) and TNM-C4942TDR (outdoor model) operate at 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. This makes exporting and importing them simpler and, as such, results in shorter lead times.
