A lot of friends found that the dash cam appear heat-up, even hot during using,so they worry it is not normal.
In fact, it is normal. Because the 4k dash cam is HD video recording. While driving, the dash cam keep recording and the chip is in high-speed data processing, therefore, will generate a lot of heat.
You can compare, when you use iPad, mobile phone, laptop to watch the HD movie, it also can be very hot. There is no problem as long as it doesn't affect normal working.
In addition, remain everyone to best to buy a dash cam in metal.because the thermal conductivity of the metal is good so that it emits the heat. And this is the reason why the metal dash cam is hotter than plastic dash cam. The plastic is not good for guiding the heat out.
