Thermal IP 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 PT Mount, 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 PT Mount preserves more image details and compensates those areas that might be overexposed. Overall, the thermal network camera offers better detection to achieve great performance of the video analytics.
