Doorbell camera

Can the Alarm.com Doorbell Camera be used without a chime?

Yes. However, the power requirements are different when installing an Alarm.com Doorbell Camera without a chime.

The Doorbell Camera will either require a 10 Ohm 10 Watt resistor with 5% tolerance on the existing AC

transformer's circuit or a DC adapter rated at 12 VDC 0.5–1.0 Amps.

Installing an Alarm.com Doorbell Camera without a chime is typically done for testing or demonstration. It is

recommended to install the Alarm.com Doorbell Camera in an existing doorbell circuit (i.e., a circuit with a doorbell

button, chime, and transformer) to make installation easier and to provide the most usability for the customer.

The transformer should be rated 16–24 VAC, 10 VA for a single Doorbell Camera. A 10 Ohm 10 Watt resistor with 5%

tolerance must be used to replace the chime. The Doorbell Camera must function as part of a complete circuit, meaning

it requires direct power on one side and a wired doorbell or the resistor on the other.

Caution: Failure to install a 10 Ohm 10 Watt resistor with 5% tolerance when using an AC transformer with no chime

may result in damage to the Doorbell Camera.

For all setups with a standalone AC transformer and no chime, use a 10 Watt 10 Ohm resistor.
