A:Answer Yes, both cameras are powered off your car's battery through the front camera. I power mine with an always on 12 volt socket in my car. I have 2 sockets. One that is always on and one that shuts off with the key. You can buy a battery pack to run it off instead of your car battery, but they are expensive. I leave my run 24 hours a day and has never ran my battery down far enough so it would not start after 2 days. You can set the voltage in settings to any voltage you wish to shut off the camera so it won't run your battery down that low so it won't start. Of course, i have a good battery running at full capacity(like new!). If yours is not in good condition, I might not leave it on. I have a lot going on around my home, so i leave mine on in hopes of catching something interesting!
Hope this helps!
