How to charge your doorbell camera batteries
Our batteries are rechargeable. You can find a USB slot at the back of your doorbell. You can use a 5V1A charger and a USB cord to recharge it.

Charging Methods
-
Direct Charging: There is a USB port at the bottom of the camera. You can charge directly with a 5V1A charger and USB cable.
-
Removable Battery Pack: You can take out the battery pack. There is a USB port on it too, through which you can charge the battery separately.
