AZDOME M550 Pro 3-Channel Dash Cam vs Rexing C2 Pro 4K Dual Dash Cam

The AZDOME M550 Pro is the better pick for most shoppers because it records three channels, has a larger screen and includes GPS. The Rexing C2 Pro is a solid two-channel 4K setup with wide 170-degree lenses and no lithium battery, which helps in hot climates. Reviewers praise the Rexing's easy install and 4K quality, but some complain there is no manual video lock button and clips are hard to save before loop recording overwrites them. Choose the AZDOME if you want front, cabin and rear coverage with GPS built in; choose the Rexing if two wide-angle 4K channels and heat tolerance matter more.

• Choose the AZDOME M550 Pro if you want three-channel coverage, a bigger screen and built-in GPS for recording speed and location.
• Choose the Rexing C2 Pro if you want two 4K channels with very wide 170-degree lenses and a battery-free design that handles heat better.
