Hello. I have decided to have a Kenwood DRV-A601 front and KCA-R200 rear dashcam fitted by a VW dealer nearby. This is because vehicle is still under warranty and they would warranty their installation too. They have quoted a very good price. My question is about the wiring. The dashcam does not have a battery but a capacitor to maintain power on shutdown to avoid corrupting the file being recorded. In parking mode, it switches on for 30 secs if it detects movement and then switches off to save the vehicle battery unless further movement is detected. In initial discussions with them, they said that the front dashcam would be hard wired to a switched feed (the rear dashcam takes its power from the front one). I then pointed out that it would have to be a permanent feed because the Parking Mode would not work. I was advised that the hardwiring will go into a combust unit which lays dormant until there is any activity. When there is any movement the unit will wake up for the 30 seconds and then shut back down, meaning that the car battery will not go flat and is the same unit which runs the vehicle alarm system. So, apparently, the combust unit is triggered by motion. Does anyone know any more about what a combust unit is and does anyone have any suggestions about whether it should simply wired to a permanent live or to this combust unit?
