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.
Connect an Alarm.com Doorbell Camera to an AC transformer
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.

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