[solved] zmtrigger question / problem

[kylejohnson]

Yao everyone,

I want to use ZM to record based on external triggers, using zmtrigger. I have a question and a problem:

EDIT 1: I got the port binding - not sure how, but it works.
<del>Problem: I have checked the ZM Trigger box in Options -> Systems and the log files say that zmtrigger is starting, yet the port (6802) is not open (netstat -tap). What would cause this?</del>

Question: Is it possible to start recording based on 2 triggers? What I mean is, I'll have two conditions - an external trigger interfacing via zmtrigger.pl, and motion being detected on a separate monitor. If there is a trigger via zmtrigger.pl, and motion is detected on monitor 1, record monitor 2. Can anyone advise on how I can accomplish this?

EDIT 2:
I am going to write an intermediate program that will do the condition matching, which will then send the command to zmtrigger.

Most likely You need to disable the serial interface try starting zm trigger from terminal it will tell you what wrong for the most part.

I really don't understand what your asking.

I believe this was what made it work - thanks.

I did do a pretty poor job of describing my problem. Basically, in modect, a monitor records when one trigger or condition is met: movement. I need two conditions to be met before recording starts, so I am going to use nodect mode and zmtrigger.pl

External Sensor 1 -> Serial -> Custom Script -> If both are met -> zmtrigger.pl
External Sensor 2 -> Serial ------------^

I am going to do a more detailed write-up of my solution once I have everything finished.
Does that make any more sense? (probably not)

I understand it
Should be fairly simple to do even with a single rs485 link. zmtrigger will handle the trigger so long as your script/program/etc can handle recieving the data and handle the logic, the rest should be fairly strait forward to pass to zmtrigger.
