Thermal cameras and analytics: a perfect partnership
Together with intelligent analytics, thermal cameras detect people, objects and incidents in complete darkness or in other challenging conditions such as smoke and dust. The high level of contrast in thermal images make for great accuracy when thermal cameras and analytics are used together: false alerts are kept to an absolute minimum because environmental conditions such as lighting changes, rain, snow, moving vegetation, insects, reflections, and shadows are much less likely to erroneously set off alarms.
Protect your premises
When equipped with the AXIS Perimeter Defender or AXIS Guard suite, Axis thermal cameras send accurate notifications to alert staff to situations where intervention is required. Or visual cameras can be triggered to start recording or to zoom in on an area when a thermal camera detects an intruder, allowing security staff to visually access the situation and then act according to what they find. The result? Organizations can protect their premises without the need for constant staff presence.
Far + wide + sharp = accurate
AXIS Q1942-E features VGA 640×480 thermal resolution for wide-area coverage and a long range: in other words, a single camera captures events taking place in a large area and at great distance. In addition, thanks to a combination of dynamic histogram equalization, enhanced local contrast and dynamic sharpening, AXIS Q1942-E improves image contrast for sharp video with great detail in all conditions. Electronic image stabilization keeps the picture smooth even when the camera is exposed to vibrations. The result is outstanding detection capabilities and fast and easy visual verification of the nature of detected events. You can either dismiss them – or do something about them – so false alarms are kept to a minimum.
Thermal cameras are a powerful tool in combination with video analytics to detect intruders or other unwanted behavior in the area of interest. In order to have a reliable and efficient surveillance system, the primary object needs to be visible. Sometimes it can be hard to filter it out if the background changes a lot, for example if large cold/hot objects are moving in the scene. Thanks to the enhanced automatic gain control in AXIS Q1942-E, the background is stable and remains almost intact, reducing the risk for false alarms. The effect of hot objects in the background is minimized, helping to improve detection. In addition, AXIS Q1942-E preserves more image details and compensates those areas that might be overexposed. Overall, the thermal camera offers better detection to achieve great performance of the video analytics.
