With the exception of the Base Station, SimpliCam Indoor Camera, and Key Fob, all of the components for our latest SimpliSafe have batteries that can and should be replaced periodically. When a sensor needs new batteries, your system will display an error message on the Keypad. 

The Base Station requires specific rechargeable batteries; and the SimpliCam Indoor Camera and Smart Alarm Indoor Camera only function when connected to power, rather than being battery operated.
