Hi, I'm in the process of taking over a 2gig and was wondering if there is a way to trigger a 3rd party DVR via the sensor inputs on it.

The DVR has sensor inputs (both NC and NO) that when activated will start recording
I was looking at board on the 2gig and was thinking I could use the bell connections (5 and 6) and wire them to the NO sensor input on the DVR

does this seem plausible or is there a better way?

I'm new to security devices so forgive me if this is dumb question.
