Yes, I checked the link and it lists ADC-V520IR as supported.
Correct, this is an Alarm.com compatible camera.
You may be able to reuse the camera. Cameras can only be linked to one account at a time, and based on historical posts the cams are usually left attached to accounts from that service provider. It will need to be removed from your existing account prior to using it through Surety. Cameras can only be attached to one account at a time.
I believe my window sensors (2GIG DW10-345) are supported as well.
The DW10-345 is compatible. The Sky Panel also uses very simliar sensors, designated DW11-345. these are not compatible with the 2GIG panel.
Another question if I may, are there resources you can point me to regarding wired door sensors and the 2gig 2GIG-CP21-345E panel?
If looking to use existing wired door contacts, you would want the2GIG TAKE-345 Super Switch. This converts wired contacts into wireless. An installation guide can be found through the previous link.
This won’t work with wired life safety devices ( Smokes, Carbon, etc)
