alarm scores strangely high. reduced by restarting zm

[FuriousGeorge]

I was having a heck of a time with my motion detect sensitivity. It seemed that it was either too sensitive, or missing everything.

I'm starting to notice that it actually works fine, until there is an alarm. Given enough time, all my monitors will go into a perpetual alarm state, even if the lights are off. If i look at the stats I can see that the frames will be getting scores in the 60s, until i restart the service. Then they will drop to 5 - 10.

The average 'pixel difference' will remain the same.

I figured it out when a monitor went into a perpetual alarm state, and I accidentally raised the sensitivity, instead of lowering it. The alarm state ended, and didnt return (for a while). It seems that just resetting the one monitor is enough to temporarily fix the problem.
