What kind of batteries does the Image Sensor use?

Battery compatibility 

• Lithium AA 1.5 Batteries (included in the box) are the recommended battery type for the Image Sensor.
• The Image Sensor can function with Alkaline AA batteries, but they're not recommended as battery life may vary.
• The Image Sensor is not compatible with High Capacity Lithium-Ion (3.6 V) batteries, which require an extra protection circuit to verify the voltage/current is maintained at safe and expected levels. Alarm.com Image Sensors do not have the extra circuit, so a Lithium-Ion battery may damage the Image Sensor.

Low battery threshold

The threshold for low battery on the Image Sensor varies based on the type of batteries being used.

• When using lithium batteries, the Image Sensor reports low battery when it receives less than 3.05 volts.
• Image Sensors using alkaline batteries report low battery when they receive less than 2.6 volts.
