Interesting (working my way thru all these devices may put me to sleep soon; I’m fighting the pollen for air).
This is the first one to show any wiring details. Appears that both cameras, along the bottom edge, can be shifted by between 120° and 180°, so facing “front” or “back” depends entirely on how you want to position/use it… that and the WiFi capability are key. With a 12V power bank this would probably make a decent body-cam (see other comments). With both lenses pointing the same direction, you can now easily (for values of “easy”) process stereo image data (I think I’ve talked myself into it).
NOT sure about the Easy Installation bit where supposedly “it will then record everything without you ever having to press a button.” Notice the bits about what memory cards you CANNOT use. Also notice the graphic showing the notch on the back of the device to allow you to easily mount it to an adhered matching plate, on the window or whatever (nice).
