Device Heating?

It is normal for the dash cam — like any electronic device — to generate some heat during operation. The FREEXAR dash cam is designed to operate safely within a temperature range of -4°F to 158°F (-20°C to +70°C) and has passed laboratory high-temperature stability tests.
Multiple ventilation openings are built into the top and bottom of the unit to ensure safe and reliable performance under various driving conditions.
Note: For your safety, do not operate the device while driving.
