Video Phone Charging
The video phone contains 2 lithium -ion batteries 18650
with long service life, which, when fully charged, can
withstand up to 6 months of continuous operation
depending on the number of activations and the
ambient temperature. Batteries are integrated in the

simply remove the doorbell from the holder (unscrew
the safety screw).

5V/2A power source.
Full charging lasts approximately 4 to 5 hours. The
