I have 7 Cameras and all are battery. I received a double charging station but my batteries are only lasting 1 day it’s getting tiring to have to change them every day . All the money I have spent wish I could do the wire instead. Not so happy customer
Then you need to “turn down” your settings for your cameras so that they don’t wake so often or record motion as often.
Using solar is a very viable option as I have 2 that use solar to charge their batteries quite successfully.
