Thanks to whoever recommended Ring for a security system..

I've already got the doorbell, thinking of replacing my defunct Brinks system with the Ring. We're doing some painting of the walls in our downtime working from home, and I already removed the fire/smoke detector and the siren. Next step will be the control pad in the hallway, and probably the motion in the living room. I just need a few door sensors, and maybe the floodlight camera too. The floodlight up there now is busted and needs replaced anyways. Does anything need hardwired or are they all using batteries? I get decent life out of the doorbell battery. Installed it after Christmas and I had to charge it for the first time in early March.

The base station and signal extender stays plugged into an outlet. The keypad panel is rechargeable with a micro USB but only needs charging once per year or something.
