ZMTrigger

About

/usr/bin/zmtrigger.pl is an optional perl script for zoneminder. See the script for a brief description. One way it can be used is to overlay text information from an outside source (say a temperature sensor) onto the video feed.

Configuration

Enable it first, by going into options, config, and clicking Enable Triggers.

Then # service restart zoneminder

Verify it is running with ps auxw | grep zmtrigger

Overlaying Text Data onto a Video Feed

After you have verified the script is running, test it is working.

Choose a monitor, say monitor 1, then add %Q to the monitors timestamp section.

The monitor must be in either modect, mocord, or nodect mode.

Open the video feed for monitor 1.

Then type in another terminal telnet ipaddress 6082</code in the telnet session type the following 3|show||||testingOSD then press return.

Refer to Documentation for what this command means.

If done correctly, you should immediately see testingOSD in place of the %Q you put in the timestamps section.

For more examples of how to use ZMTrigger see the forums.
