Help desk: How sensitive is your motion detector sensor?

Recently, I blogged about using the motion detector sensor to increase the security presence of your data center. Well, expanding on the topic, I thought I would answer one of those frequently asked questions I get from customers using the motion detector to beef up security. “How do I keep the motion sensor from being set off by very small movements?” The answer – you can adjust the sensitivity of the motion detector using the sensor status filter.

The sensor status filter allows you to enter a time delay that must occur before the sensor changes status, thus filtering out noise in the signal. This avoids unnecessary sending of notifications, as fluctuations can occur during normal working conditions.

To find this setting, go to the Motion Sensor Settings page of the web interface, and click on the sensor status filters button. Change the “Continuous time (secs) sensor is to report” field to some value other than zero. 1 second is a good place to start, but it all depends on your specific working conditions.

At any rate, increasing the continuous time to report field a bit can help keep you from getting false positives and give a little extra room for normal environmental shifts.

Stay tuned to the Ravica blog for more helpful environmental monitoring tips.
