1. There is no such option. Should be an easy source code change to allow
it, but I haven seen anyone implementing it.
To reduce bandwidth you can also try to build a development branch that
creates secondary stream with reduced resolution:
https://github.com/Motion-Project/motion/pull/454
2. curl -s http://localhost:8080/0/detection/pause > /dev/null

An alternative which (I assume) should save a fair amount of
processing might be to specify a mask which ignores the complete
image.
Depending on what type of stream you are getting from the camera you
may find that the actual motion detection is not a large percentage of
the processor load. For example I have an H.265 rtsp stream which
motion has to parse and most of the processor utilisation appears to
be just the process of following the stream. Which is an interesting
play on words as the camera is in fact watching a stream (of the wet
variety).

unfortunately I'm not familiar with this/any C code, but if someone is
out there, who sees this as an easy source code change, he/she is warmly
welcome to do it !
I guess I'm not the only one who wants save network bandwidth, save disc
space and probably CPU load with all following positive aspects

I measured no change in CPU load, are there more such commands, I didn't
found any documentation about this
