I'm looking for a dashcam to use for surveillance. Needs to have very reliable motion detection (preferably with buffer) and work well at night. Also needs to have a built in screen for video review. I don't care about any other features like GPS, G-sensor, etc. It can have those features or not. Also should be able to power it from a USB battery, but I think all of them do that. All-night built in battery would be a icing on the cake but I can live without that, especially if it adds to the cost.
