If you need to power your ADC-VDB770 Doorbell Camera and you don't have existing wiring, or if the existing wiring is incompatible, then the ADC-VDBA-PSU-DC is for you. This is a plug-in DC power supply that will provide reliable power for the ADC-VDB770 Camera.

The ADC-VDBA-PSU-DC is rated at 16 Volts DC, 1.25 Amps, or 20 Watts. It is used when the ADC-VDB770 cannot be set up with an existing doorbell chime circuit for power. It should only be used when there is no wired chime used in the circuit. The power supply can be used with or without a power module. If a power module is used, then you will need a 10 Watt / 10 Ohm resistor. If no power module is being used, then a flameproof 5 Watt / 3.9 Ohm resistor is needed. You will also need to supply your own wiring.

When the power module is not used, power will be running through the resistor at all times. This is why it is very important to use a flameproof resistor in this scenario. It is also important to be sure the resistor is thermally isolated from any flammable materials within the installation. Since both the power module and a 10 Watt / 10 Ohm resistor come with each ADC-VDB770, it is recommended that they both be used.

It is recommended that video doorbell installations use 18 AWG - 20 AWG wire. Using a smaller gauge wire, such as single-strand Cat-5, which is rated at 24 AWG, may not provide sufficient power to properly operate the doorbell camera. The ADC-VDBA-PSU-DC will usually be used in a situation where no existing chime wiring and hardware exist. In this scenario, the ADC-W115C Smart Chime can also be used to provide a doorbell chime sound. Multiple ADC-W115C Smart Chimes can be configured to work with each ADC-VDB770 on an account.
