Blackvue are reticent to tell you exactly what they do ( No wonder as they want to charge you £169 for a 128gb sd card that can be had for £34 elewhere! ) but you either need 5 Volts or your vehicles standard 12v
Most cameras these days are powered from a 5 Volt source with a simple voltage regulator circuit in a cigar plug connector. If it has a USB type connector on the Power Supply or both ends it's going to be 5V in to the camera.
There are several options for powering the camera. The 12v Auxilliary connector in the footwell of the R171 is a good one but requires the cables to be run down behind all the interior trims and behind the cubby or under the footwell panelling.
The best option is to pick up power inside the housing behind rear view mirror. There is permanent 12v there for the cabin light's , GPS system and rain sensors on all series.
You can get a small, switching power supply ( very low heat generation ) online from various providers which will convert 12 - 30v to a solid, stabilised 5v supply that can be mounted in the rear view mirror mounting but be warned that of several I have used most caused very bad radio interference and even GPS signal blocking. If you are going to use one of these units a good plan is to 'pot' it in a small cast aluminium enclosure using a shielded cable pass through and ground the housing. This will shield the GPS and radio from the radiated noise.
Alternatively use a linear type power regulator which will not radiate noise but will need some sort of heat dissipation scheme as some cameras can draw quite a bit of power with resultant heat losses.
