I recently bought the battery version so that I’d have battery as a backup and full power so I don’t need to charge the battery all the time. I ideally need a 15-20 foot cable based on where the camera is installed. I’ve looked everywhere and even ordered what turned out to be the wrong cable off of Amazon. Does anyone know how to install an indoor camera with plugged in power and also battery for backup? And also where to buy a cable/adapter for my new Ring Stick Up Cam Battery 3rd gen camera? I just want this thing to work without being a big PITA.
