What is the difference between the Alarm.com ADC-VDB105 and the Honeywell DBCAM-TRIMBR. Both are Skybell "Slim" or "Trim" models. They look very similar. Do they both work with Alarm.com? How do I add a doorbell, or any camera for that matter? I don't see a way to do it on my app or when logged in on the browser. Thanks for the help.
