What is the lowest battery voltage to start TDI Touareg?

I just purchased the single channel Blackvue dash-cam, which comes with a parking mode feature. It is recommended to get a battery discharge device to prevent battery drain. There are several devices that have voltage settings, but I was not sure if I should get something with 12 volt cutoff or something higher.

I am looking at the following:
MotoPark Multi Safe - 12.2 cutoff setting
Itronics Itv-80 -12.2
Blackvue Power Magic Pro 12.0

Thanks

Battery voltage is only a rough indication of the charge state of the battery. Other factors such as temperature and battery condition will also affect the ability to start the car.

As a ballpark figure, at 12.2V you'll have 50% charge. At 12.0V you'll have 25% charge.

Personally, I'd be going for the 12.2V cut-off.
