Incorporating sound

Question

I am interested in incorporating sound in some way. If a sound is detected by an external microphone I want to activate Motion as if there was movement. Would some sort of interface to xml-rpc be best for that?

Environment

Motion version:	3.1.19
ffmpeg version:
Libraries:
Server OS:

Answer

Actually this is an interesting idea. And not new.

I have personally played with the idea of using a passive infrared detector to trigger Motion for cameras where background motion is making video based motion detection less effective.

So I will add a detection feature to the roadmap.

I think the way to implement it is to make a http interface (xmlrpc dies with 3.1.X) call that triggers motion for a defined time either as picture frames or seconds.

Today there is an option you can set by xmlrpc called output_all

See MotionGuide#The_output_all_Option

You will then need to send a remote command to start and another to stop forced motion detection again. I guess this is what you are looking for.
