    I have an alarm which resembles this,

    What is required to connect this to the jumpers located on the back of the NVR?
    I believe 12V DC is required, but I don't have that power cable
    Also, what alarm cable should I buy?

    Thanks

    Been dealing with stray cats, squirrels and raccoons eating our tomatoes and cucumbers (not that its a bizarre situation, lol) :D

    Arjun,

    I used a 12v supply located next to the NVR. I also used a keystone jack. I punched down conductors to the jacks, and ran them like this:
    - NC on NVR alarm in contact
    - NO on NVR
    - Com on NVR
    - +12V in
    - +12V
    - 12V gnd
    - 12V gnd

    I used cat 6 cable to run from the keystone jack to the sensor. I had it on hand, and figured it was simpler to "standardize", using the same cable and connectors as for the cameras.

    At the sensor, I did something similar.

    Try this wiki and links:
