Trying to negotiate the dashcam minefield

[KarlBristol]

I'd been toying with the idea of buying a dashcam for some time.... I've just bought a new Nissan Xtrail and at two days old someone has handily driven into it and driven off leaving no details. This has really pushed the dashcam situation to the front of my mind again. I've done some research but it is a complete minefield.

I have a few criteria and was wondering if it was possible to point me in the right direction;

- Small camera easy to conceal
- No major wiring (Cables easy to hide)
- WiFi
- Ability to record if activated by movement or movement to the car when the car is off
- No HUGE price tag

Any help would be greatly appreciated
