What types of cameras are not supported by the ADC-VS121?

To determine if the analog camera is compatible, verify if it has an HDMI to Coax connection. Alarm.com video servers are only able to be used with a true analog connection. Most HDMI to Coax cameras have a switch to toggle from HDMI to true analog, this typically can be found in the analog camera's installation guide. 

Note: The max input resolution of the ADC-VS121 is capped to what analog delivers (D1 Resolution or 704 x 480).
