I bought C5 model for my car. Decided to use Innovv camera, because it has separate camera and DVR units and that allows discrete installation.
Had some worries about power supply, because my car has start/stop system and can shut down petrol engine at any time and after that to trigger starter again and voltage drop to about 10 volts at that moment. I tested before car installation C5 with its original power module to power from regulated power supply at home. And it works well and stable from 9 to 15 volts. After installation on the car it also work well with car start/stop system.
I measured also, that in "stand by" mode C5 consumes only 3.5mA current, that is very good.
But I have some more questions:
1. How "G-sensor" option works - motion detection in front of the camera, or a shock sensor inside it. If it is a shock sensor, where is it located - in camera module, in DVR module or in power supply module.
2. Is power consumption in "stand by" mode depends from "G-sensor" option turned on or off? If it is "yes", how much is it?
3. Does the power supply module is just the power converter from 12 to 5v with added +10 seconds delay on on/off operation? If it is just the power supply, then:
a) If camera/DVR detects "G-sensor" event, how it can turn on to record that event.
b) How DVR can properly finish recording of currently recorded file, when power supply is turned off.
From curiosity point, I opened the DVR module to see if it contains Lithium battery or some capacitor... but it does not. There is only one very small 621 battery and I thing it it rated to only 5.5mA and can not supply camera in recording mode. I measured DVR consumption, it is about 200-250mA at recording. So, the small 621 cell battery seems to be used only to hold timer and other DVR settings, but not to recording after drop from external power supply.
