Best to use external Motion Dection signal via CAMERA Hardware or via Computer/ZM?

[777funk]

I have an IP Cam (Axis 210) that has an input for a trigger (i.e. PIR sensor). I can easily trigger the camera to output upon motion but would it be better to send the signal to the computer (serial port, USB, another method???) instead and have it record that way? It would surely save on processing power (vs software MoDect) either way, correct?

If you use camera motion detection it reduces load a *lot*. I briefly used Foscam's hardware detection with ZM - but unlike Axis, Foscam does not have a hook - I had to poll.https://github.com/pliablepixels/ZoneMi ... mHDTrigger

If you go that route, use zm_Trigger

What's entailed to have triggers connect to the computer? I'd guess there'd be a way over ethernet?
