A multi-sensor PTZ camera is a specific surveillance camera that is equipped with multiple sensors and lenses typically such as HD visible light cameras and thermal imagers, or other detectors, which can capture accurate video footage or data in different scenarios from different angles and perspectives. 

For example, multi-sensor PTZ cameras can be used to protect border areas, critical infrastructures and military installations day and night, including monitoring illegal border crossings, smuggling activities, and other potential security threats. Some cameras have automatic tracking capabilities, which can be used to detect and track moving objects in real-time. 

Additionally, multi-sensors cameras are increasingly used in factories and laboratories and combined with robots. The build-in various detectors can help people remotely monitor the site and obtain real-time data.
