I have a few Ring stick up cams installed around our house. I couldn't fit the doorbell on our front door frame because the wood frame wasn't wide enough where our current doorbell/wires is/are and the door frame is set in brick. All ours are battery operated and only need recharging around 1x/month, depending on how many alerts they get and actually turn on. As many have mentioned Ring sells a solar panel you can hook into the charging port, which may not be that easy on a doorbell as far as running a wire and placement. ANY of these camera's are only as good as your wifi connection/strength at their location. I would make sure you have a wifi hotspot or amplifier as close to the doorbell as possible. Our front door cam is farthest away from our hotspot and also has 3 walls between them, so sometimes it alerts as someone is already walking away from the camera/front door. All the Newer rings are now 1080p and the newer stick up cameras have a removable battery now where the older ones required removing and plugging in the entire camera for charging.
