How to Solve the Heat Problem of Dot-Matrix LED Infrared Cameras?
1.Reduce the current.
Use small power infrared lights instead of big power infrared lights. This can reduce the amount of heat, but the effect of long IR distance is not as good as that of big power infrared lights. 

2.Add cooling fan inside the cameras.
This works but it has high demands of fan testing and camera housing design.It should ensure good appearance and practical.

3.Use constant current power supply to maintain constant current and control heat of LEDs.

4.Arrange LED lights in groups.
 For example, 24pcs LEDs,it can be arranged into three groups to reduce heat.

5.Choose good materials. 
LED board and camera housing can use aluminum and other good material for heat.
