    if wires could follow the fence that would be easiest (probably longer), but total distance matters due to voltage drop. I'm not sure the electrical specs for the cam i/o or if you can drive a contact directly. I know there are other threads on this.

    The only way to use that wireless sensor would be with a honeywell alarm panel, you'd have to configure an output to follow that zone and you might have to add a zone expander to do it. Then you'd hook that output to the camera.

    There are some other wireless products that could work too like this: http://www.dakotaalert.com/catb2b1/product_info.php?products_id=208
    but wired will be more reliable.

    I wish alarm companies would come up with outdoor rated wireless sensors. Many burglaries happen via unlocked side gates.

    There are some like the one in the first post of this thread...

    The issue is they'd never really monitor them. They aren't going to send the cops because the wind blew your gate open. But a bell squak might be enough to chase somebody off.

    On a normal alarm circuit the current is so low as to make cable related voltage drop irrelevant. On the other hand, a nice long cable on a high impedance input makes for a brilliant antenna for EMI and lightning induced equipment destroying spikes.

    I had to gate openers fragmented due to this. Finally buried all cable to gate (power, cat) and no problems in the years since
