I absolutely love these cameras. I already had the ring doorbell and needed some extra surveillance in the common staircase cos my neighbour tenant is very nasty and likes to wreck my business signs and steal my stuff. I didn't want to install anything that required an electrician and this is the perfect solution. It comes with 1 standard battery for each camera but I bought an additional 4 batteries to utilise both battery slots in each camera and 2 spares to swap out the battery when necessary.
I would say that the device can run on a pair of batteries for 2 to 3 weeks without replacement in a medium traffic area. It is also pretty easy to change the battery (provided you don't install it in super high places) and the Ring app is amazing at informing me when someone is in the building. It is also great value to get this 2 pack and it is one of the most reliable and cheap solutions out there for surveillance.
The only negative is that the camera that is a bit further away from the wifi source in my office do suffer from some connectivity issue. I tried using the Chime pro extender to increase the wifi range but that thing totally did not work for me and just refuses to connect. If you have to go through too many walls or the distance is too far, this may not work well for you.
