A:Answer The batteries are rechargeable. They are built in, so when time to recharge, you just take camera down and plug camera in to recharge. Battery life should be 6 mos. up to 1 year depending on how you have camera set up to record. As far as memory storage is concerned, it is built in, and cannot be expanded, but is not a problem. Cameras do not record constantly, only record when triggered by movement. The built in storage is more than adequate, and if capacity is reached, newest files will over write oldest files, likely to be many, many months old, if not more. Video quality is excelllent, IMO better than equivalent Arlo model. Very satisfied with my setup.
