We're using Pelco D/N cameras and a Dedicated Micros DVR ported to a security panel for monitoring of video motion outputs. The problem is that even with sensitivity on low the system triggers on rain in the lights and mist from the site (composting material). This creates the problem of excessive activity in our monitoring center which, if we enabled it, would lead to excessive activity charges.
I'm looking for ideas to decrease the sensitivity or otherwise increase our confidence in the activity detection. We are discussing using motion detectors, PIR, in a cross-zone configuration but the challenge is the distances involved and the lack of wire/power sources for the various views.
Ideas? How do you guys deal with outdoor motion sensing and the need or not to view live video for verification?
