How do you know the battery is low or needs changing? Is it app friendly? Is the a minimum for how many can be set up on the same system?

You are able to set-up low battery notifications as well as monitor battery status within the APP on your compatible mobile device. You can have up to 10 Blink devices per sync module as long as they are all within the 100ft operating range of the sync module in any direction. The cameras on the sync module can be in any combination.
