I personally have not done it, but might look into the center mirror or sunroof wiring harness.

This company has been making Y-splitter pigtails for the mirror power, but doesn’t make one for the Volvo. It’s a good idea that’s also clean.

Convert your mirror into a power source for your dash cam!

Below is a Volvo thread on a dash cam install. While this member wants continuous power, the thread goes over the what is needed for (ignition) switched-on power. You could try running a fuse-pigtail (add-a-circuit fuse) in an unused/open fuse location in the dash fuse block, then wire under the A-pillar trim to the top of the windshield. Confirm the open fuse location is switched on/off.

One thing I do like is power that is turned on when there is a trigger, like the lights turning on with the door unlocking. This way if I am loading groceries or the ignition is switched off when pulled over exchanging info from an accident, there is a time where the dash cam will keep on recording. I have this in my BMW using one of the DC outlets located under the dash. I haven’t looked into doing the same with the Volvo. Who knows, maybe it’s not monetarily feasible, like adding a door/alarm chirp.

I know that some dash cams have batteries or capacitors so it will keep on recording for a few minutes after power is turned off. Capacitors are better because the batteries tend to overheat with the windshield sun exposure and black cam housing absorbing heat.

Good luck. Keep us updated with what you end up doing.

Hardwiring a dash Camera - Some Guidance = Or have Done...

So I'm sure several people read my thread about that nasty scratch on my passenger door. Whether it came from a cart, key, etc, I made the decision to get a new Dash Camera. Next time, if it was some idiot keying my car, they'll be on video. Or I can see what exactly happened...

Wondering if this will be enough to cause some parasitic drain while the car is not driven in a few days?

I have dashcams permanently plugged into both the center console and the rear cargo 12v outlets and often leave my car without driving for a week or two. Never experienced any issues with the battery being drained because of it.

 

Yes, I left my dashcam plugged in to the socket. Never experienced any issues.

 

Mine is plugged into the OBD2 port. To be clear, no splicing involved, but rather my dash cam offered an OBD2 plug as a power source option.

 

delete, sorry. Wrong model.

 

Ok. Thanks for the replies will just fuse tap into the 12v cigarette lighter circuit.
