Would you like to buy a wireless dashcam? A dashcam never has a (large) built-in battery or battery and must therefore always be connected to the car with a power cable. So a dashcam is never actually wireless. For a wireless car camera, you can therefore consider using an action cam with a built-in battery, such as those from SJCam. Of these, you can usually charge the battery so you can use it in the car without a cable. They have a special car stand with Loop recording so they act as a dashcam, however, they often don't have GPS, G-sensor or parking mode.

The cable that comes with a dashcam is always very long (usually 3 to 4 metres) so you can hide it easily and unobtrusively in the car. You then don't bother with the cable while driving and it is hardly noticeable. You can also consider using a continuous power cable that you can install near the fuse box or using a battery pack or power bank.

Connecting the rear camera of a dashcam wirelessly is also unfortunately not possible. The rear camera of a 2CH Dual dashcam is always connected to the front dashcam with a long cable. The rear camera receives power via this cable and this sends data to the front dashcam where the images are stored. Using a front and rear dashcam wirelessly is not yet technically possible.
