should I connect the device to always on power 12V or power on with key in?

I don't connect it to constant because it could drain your battery. I rely on the back up battery when the car is off.

12v on all the time. If car is turned off you will never find it.If your tracking your kids and there over a friends house and you want to know if there there. and they have the car off in the drive you will never track them cause you dont have a constant 12 v on all the time. hope I answered your question. At least what I told you works for me.

Always on so if the car is parked you can track it, I think it does have a battery back up, but thats the way I did it.

A simple answer, no. Sorry, but if your savvy you can tap off an acceptable lower voltage and run the device perfectly fine.Just my opinion.

No problems here. Mine is attached to my keychain and only comes on when I turn it on.

It depends how you set it up and want to use it. If you want to power it on and of at your discretion and not set it up to go on and off with the car then you'll want constant power. If you set the system up to go on and off with the car then you only need power when the car is on.

I had a spare 12V, 3.75A from a Samsung monitor lying around so that's what I used. Almost any 12v power brick will do though.

C is needed if you want to power the device and use it as a repeater. Otherwise you'll be on battery.

Your Battery Tender will turn that on. So I just disconnect one of its power wires when ever I am using my Battery Tender

Have a look at the back of your power brick (you may need magnifier, I do), it will have an output value saying ___ VDC. If that is 12 or 19 then you should be good to go.

You'll need apower inserter & a 8-way switch asdepicted here if it works. http://i.ebayimg.com/00/s/NTA0WDk5OA==/z/niwAAMXQm7FR6qzq/$T2eC16J,!yUE9s6NEGyfBR6qzqT-Kw~~60_57.JPG

I use auto. Might as well let it figure when it needs power. No sense leaving it on 24/7.

If you wire the system to the ignition so when the key is off the power is also off so it won't drain your battery

It power just like your old keypad. I advise keeping your old keypad connected also. You just got to change one setting.

No cause I have 2 p3 12's and it goes into protection mode it's not enough power... That's my opinion

You can use either one, depending on where you are, and what voltage is supplied. You can also use an adapter. What is important is to supply at least 500 ma of DC voltage. Hope this helps. CW

Agree with Bruno. I only need to plug it in for power...wifi connection is wireless

Yes. Leave it on. In fact, if there is a power failure the whole re-booting, re-linking process needs to start over again from step-1. It's an overly complicated and one can tell Philips designed it, not Apple.

I do not have it hooked up as "always on" so I can not answer your question. I hooked it up to the back up light power line so it only comes on when I shift into reverse so the screen is blank until I shift into reverse then it comes on. When I put it back in drive the screen goes blank and there is no longer power to the camera.
