Why does the plastic case of the camera become hot when it is in use?

While the camera is working, the electronic parts inside the camera will generate some heat and some may find the case hot. The applicable temperature of the camera is from -10 degrees centigrade to 60 degrees centigrade. YI Smart Dashcam is designed to release heat from inside to outside very efficiently to protect the electronic components inside. Also, it uses flame retardant material in its case to prevent any potential fire.
