Eric Vasquez uploaded to YouTube a unboxing video of his Vugera UX9 (4K UHD front camera, 1080p HD rear camera) dashcam. Also look for a separate installation video showing how it was wired in his Kia Stinger.
Here is a Amazon link to the OBDII power splitter shown in the video which Eric used to power the two dashcams and his JB4 piggyback ECU.
