I'd appreciate some help here

I'm installing the two channel camera. I am having trouble getting the thing to power on. This with ignition on or off. The fuses I've tapped are working, since the car functions are intact. I'm wondering if this is a ground issue. I used the bolt next to the fusebox, but wasn't sure if there was a better option.

I'd appreciate thoughts on which fuses I should tap for constant power and switched power as well as the best grounding point.

Thanks

I actually did not hardwire mine - I just plug mine into the passenger side footwell dc plug. That way, it turns on when I open the door, and turns off after about 10 minutes after I turn off the engine and close the door. No worries about battery drain.

But I agree, one of the most common problems with connecting to fusebox is the ground. In these modern cars, screws sometimes are plastic and what you think is a good ground really is not.

Thanks, that's what I'm doing for the time being. I was hoping to hard wire so that I can use the parking monitor feature. I thought about using the battery back up, but reviews are mixed on that.

I hear you, that's a tough one. Was thinking of hardwiring for the same reason, but worried too much about battery drain, especially on Porsche batteries. Have you looked at Power Magic? It monitors battery currency and turns itself off if it senses battery getting too low. Problem with that is that it has be hardwired, so you are back to the same problem.

Yeah, Power magic is what I'm trying to get to work. Frustrating. I'm going to try the passenger side and see if I have better luck.

Here's what I did for my Rexing V1P dashcam. I wanted it to stay on all the time to record should someone hit it or mess with it.

I used the fuse panel on the passenger side footwell. Picked one of the 5A fuse and ran the ground to that nut that you mentioned adjacent to the fuse panel (closest to the firewall for reference). Anyway, didn't have an issue whatsoever with it not powering on.

For my V1 I forgot which fuse number but I found one that would only power on when the ACC is turned on or when the car is running and that was tapped on the driver's side fuse panel.

hmm...my power magic pro could be defective then. I'll try the passenger side and see.

I'm hardwired to the driver side fusebox for both my dash cam and Escort Max using that same ground nut. I use Vantrue's version of a battery-protecting hardwired cable, although I've gone back and forth a couple of times on using full time power (for parking mode) and switched power.

For full time power in a 991.1 I use fusebox position C3 (which is normally an empty fuse of my car). For switched power I use D1, which was also normally unused (rear wiper). These have been reliable for me.

Used this in my Macan, tried using in the GTS but it won't charge enough. Car needs to be driven more for it to get charged.




I ended up using the footwell plug.

Thanks all for the tips.

Tried wiring the passenger side. Found a major grounding point under the carpet and attached to this. Still no luck. I'm pretty sure the PMP box is not working. Looking at online reviews - this is a pretty common problem.

So I just routed everything to the passenger footwell. Pretty much invisible. We'll see how it goes -- I suspect I may just leave it this way.

I had the same issue with a defective unit. Suggest that you verify the unit is working before you try the hardwire ( put the leads on the battery terminals with the camera attached). Also, I suggest that you use a DC voltage tester to verify ground and positive connection.

I ran mine the same way and it stays on much longer than 15 mins. I think mine recorded for 45 minutes or more.

Have you tested the hot/ground with a multimeter? I just installed my Street Guardian and I used the bolt next to the fuse box but there was so much paint on it I had to back the bolt all of the way off and reinstall.

Any follow up to this? I asked my installer to put a Power magic pro but I don't think he did eventhough he said he did (I don't see it). I may have to install it myself.

Nothing yet. I'm getting a multimeter and will check everything out.

So you mean that you don't think you installer actually put the PMP in? Did you look inside the fuse box? There aren't many places to hide the thing. And the button needs to be accessible.
