This camera is a small form positioning IR camera, which could track 4 IR objects at the same time. The applications are various and ranges from tracking robots with IR transmitters for navigation to light barriers, or determining an objects direction.
Additionally, it can also function as a flame sensor, which could track heat sources and a flames position.
The sensor is easy to install and to connect. All you need is just four wires, two for power supply and two for I2C.

Once the camera detects a signal, it will display its coordinates on the first position. And others will be empty(returns 1023,1023). If the camera detects several objects, it will arrange them according to the detecting order. If one of them is out of the view, that position will be empty(return 1023,1023). It can only support tracking 4 objects at the same time.
