Installed this last week. Really impressed with the quality of this DDPAI Z40. It pretty much has everything you would want from a dash cam. On top of that, the app works really well too. Hard to beat at its price point.
The dash cam comes with a rear camera, built-in GPS and hardwire kit. Storage is optional so you can get your own or purchase one along with the dash cam.
Another good thing is that it uses a super-capacitor for power instead of battery which should hold up to extreme temperatures better in the long run.
