Hello,
Are you using a cigarette lighter cable or a hard wire kit please?
If the camera is always recording, then it's constantly being supplied with power.
This can either be because the cigarette lighter port is a permanent live fuse (always powered) or the hard wire kit is on a permanent live fuse.
If you're using a cigarette lighter cable, then you can either unplug the socket every time you leave the vehicle which will stop your battery from draining, or you can use a Hard Wire Kit instead. Please be aware that the cigarette lighter cable does not have an in-built voltage cut off and will drain your battery if left connected to a permanent live cigarette lighter socket.
If you're using a Hard Wire Kit, then you're currently on a Permanent Live fuse instead of a Switch Live fuse. You can either turn Parking Mode on, which will switch the camera off when not in use. Or if you do not want to enable Parking Mode, you can change the fuse position to a Switch Live Fuse. The Hard Wire Kit does have an in-built voltage cut off at 11.2V, protecting both your cam's battery and the car's battery.
If you're already on Parking Mode, then I'd recommend:
Remove the SD card from the camera, then press the reset button on the underside of the Dash Cam. Then, without the SD card inserted, please turn on the Camera. Leave the camera on and wait for 5 minutes. Does it now turn off automatically? If so, then the SD card is corrupted or is not compatible.
