622gw dashcam install

[braincell]

I have a MG4 trophy and I have just bought a nextbase 622gw dashcam with rear camera....

My app reports the resting voltage for the battery is 12.2v and the hardware kit is rated too 11.6v.

All adjustable voltage cutoffs use a usb c connector which the nextbase doesn't have.

Anyone here got a 622 fitted using the parking mode ???

Thanks

Thread 'Nextbase 622GW with Rear Cam power requirements'

Dec 9, 2022

Hi all,

Does anyone know if the rear mirror USB, on the ZS EV facelift model, will power a Nextbase 622GW with rear camera? I'm not keen on hard wiring a dashcam in a leased vehicle.

Many thanks in advance.

Thread 'Nextbase 622 dash cam and mirror housing USB port'

Mar 10, 2023

Hi,

I've had a simple dash cam fitted for a while powered from the mirror housing USB port. It's been working fine.

Decided to get a better dash cam with higher quality picture, rear camera and GPS etc.

On trying out the newer camera it was ok with just the front camera, but hooking up the rear camera it would power down.

I changed the input power to the supplied cigarette lighter and all is well.

I am assuming that the inbuilt USB port is unable to provide sufficient power. This is a shame as that means a bit more work to install a hardwire kit.

Just wanted to ask if anyone has a...

Hi , yea , I read those threads but it doesn't really answer what I wanted to know.

The hardwired fusebox and OBD will work, but , I was wondering if the 11.6v cutoff has caused anyone any problems with dead batteries

I have had the 12V battery go below 12V on 2 occasions in the 32 months I've had my Trophy. The first time at about 6 months and the 12V battery recovered when I con ected the car to my granny charger.

The second time at 26 months was more challenging and, although the car unlocked and powered up, it would not charge the 12V battery nor the HV battery, on AC nor on DC, so I had to connect my booster which must have triggered the charging circuit because all worked after that and since.

That's exactly what I'm afraid of, I can simply wire to the 12v socket and do away with parking detection but I really wanted parking with a sane cutoff value.

I could buy a variable cutoff on a usb c hardwire kit and butcher the connections to keep the battery above 12v which seems the sane value although I checked my 13plate trophy earlier on the app and it said 12.2v .... :/

The car should keep the 12V battery topped up but the circuit failed to work on those two occasions. However the rest of the time it has worked.

My 23plate (I assume yours is the same?) 12V battery usually runs between 12.1V and 12.5V when not charging.
