OK - back to the OP's question - I recommend
Rove - I've tried the cheaper units and have not been happy with them - I am very happy with this brand as it has the all the features that I want.

3 cameras that simultaneously record front, cabin, and rear at a resolution of 1440P+1080P+1080P

Built-in GPS, G-sensor, loop cycle recording, emergency video lock, Parking Mode, Time Lapse, external storage supporting up to 512GB
Instantly Access Evidence Straight To Your Smartphone with the Built-in dual-band (2.4 & 5 GHz) WiFi - you can view the dash cam’s live footage, configure its settings, download recorded videos at a rate of up to 15Mbps, and easily share
Powered by a Super Capacitor rather than a lithium-ion battery, ensuring surveillance and safety in both extreme hot and cold weather conditions from -4°F (-20°C) ~ 158°F (70°C). Unlike regular internal batteries, Super Capacitors provide a longer camera lifespan and prevents internal damage.
Smart Auto triggered 24-Hour Parking Monitor - Whenever someone hits your car while parked, and the impact reaches the G-Sensor Level, the R3 dash cam automatically turns ON and records a 1-min video, and then locks and saves it in a secure space to avoid auto deletion.
