Hardwire kit question

Quick Q: Is the ACC wire only used as a sense wire or does it switch over to this wire to power the dashcam?

I am not absolutely sure of this answer, but I believe that it is only a sensing connection. I say this because if you provide 12V to both the Battery and the Accessory wires, and then remove the 12V from the Battery wire, the camera will turn off.

Hence it is not being powered by the Accessory wire.

If/when I get a chance, I'll put an ammeter on the Accessory wire and measure the current draw.

Darn i was hoping to be able to put a switch on the battery wire so i have an option to turn off parking mode.

Thanks for the info.

EDIT: Do you know what the typical power consumption is for normal recording and parked recording?

Do you want to turn off parking mode while the ignition is off? You could just power down the camera. I have done this many times in order to retrieve the memory card to review footage.

I did some bench testing, ACC wire is indeed just a sense wire it draws no current. On 2 channel cont. recording, the Battery wire draws about 330mA @ 12.5v.

If you combine the ACC and Battery wire together and apply 12v+ it will just act like the cigarette plug version (no parking mode).

So if you want a physical switch to disable parking mode, use an SPDT switch for the Battery wire to select the source from either battery or ACC.

Typical Power consumption:
2 CH Continuous : 330mA @ 12.5v
1 CH Continous: 230mA @ 12.6v
2 CH Parking Mode: 270mA @ 12.6v
