I just installed DDPai Z50 GPS with OBD easy plug in hardwire on my old car.
It comes with a set of front and rear camera. The OBD plug in makes it easy to plug in, no need connect to fuse. DDPai OBD plug has a switch there...24 hours and ACC. From my understanding, the ACC setting will cut off power when car engine is off, 24 hours....is just that 24 hours powering. So if don't want app turn off or unsure, can just flip the switch on the OBD (if you can access the OBD port). Better than the cigarette lighter plug in. Some say OBD goes 24hours full power but DDPai OBD can sett directly on the switch. It has low voltage cut off.
The DDpai app can set battery voltage detection. I set DDPai to cut of power if battery goes lower than 12.4, the cut off power to avoid battery cannot start. The parking monitoring can set to either time lapse mode (can set 12, 24 or 48 hours before shutdown), full recording or in my case I set to sleep mode to save battery (not need record unless collision or hard vibration emergency wake). I'm not sure why other says the microphone is bad, for me, its is working ok, clear enuf.
For me, the app is working ok, nothing fancy but bad as other say. Does higher end phone makes a difference?
Also when initially connect app to ddpai, it does cut off phone data. I'm not sure how, but when after I access the live video, if I don't exit, just switch to other app with DDPAi app still running in background, I recovered usage of my data and can choose the running DDPAI app and view live video.
Good to know. I don't have high requirement for a dashcam so a basic one will do. After talking to the sales person I've changed my mind and will go with a single dash cam plugged directly to the cigarette lighter. If hardwired to some parts of the car such as battery, will void the warranty for battery with new cars. Initially thought of fixing both front and rear dash cam but reverted to just front to avoid the hassle and also the fact that the rear windscreen would have very dark tint so the rear dashcam will not be able to capture a clear video if the tint is very dark.
