Battery Video Doorbell

Having to change the battery on my ring video doorbell is a right pain. Having to go outside in all weathers (frequently) to change the battery. Dropping and losing the small screw for the battery cover. It would far easy if the battery pack was on the back of the door, where I can change the battery inside, and in comfort of my own home. This could easily be achieved by drilling a very small hole through the door to pass a small wire from the video door bell at the front to the battery pack at the back.  I’m currently looking for a battery video doorbell on the internet that offers that, but if it was something you might think of developing, I’d be happy to test it out for you.
