Problems with Night Recording As Dash Cam

[Richard.Garnett]

I have an SJ4000. I took a trip down to Manchester and set my SJ up as a dash cam.
In the day light I ended up with 10 x 10min cyclic recordings 10.4 Gb

For the return journey I ended up with 117 files 3.2Gb with the files running from 10 minutes down to 30 seconds.

The only settings that I think would have a bearing are the Car Mode [off] and Motion Detection [off]

The cam has a battery in it but is powered from a cigarette light.

Any ideas what is happening ?

First question: With Car Mode turned off it means you need to turn the camera on and off manually, i.e., even if it's connected to the 12V adapter it doesn't turn on automatically when you start the car. Is that what's happening?
