I have been doing this for more than 6 years to deal with sudden changes
in room illumination coming from outdoors (the "light switch" feature
didn't do the job for me).
Comment summary of the changes to motion.c is:
external alarm function, logically "ored" w/ video motion detection
memory-mapped file /<pidfile dir>/mdT.mmap (T=thread no.), containing
a 1-char alarm status plus \0 terminator.? file must be dynamically
updated by separate program.? alarm status may be included in
event string formats as substitution symbol "%!" for values:
* "-" motion access to memory-mapped file failed (see log at startup)
* "0" external alarm program inactive or not implemented
* "1" external alarm program operational, but no alarm signalled
* "2" external alarm signalled (only value significant to this module)
* "3" external alarm fault (as determined by external alarm program)
I'm using a Phidgets, Inc. (https://www.phidgets.com/) USB sensor device
to read PIR contact closure, controlled by a Python program using
Phidgets' Python API (one of several languages they support). With
careful coding for opening and initialization of the memory-mapped file,
I have had totally reliable operation regardless of which side starts
first or is restarted. Unfortunately, my code is based on motion 3.2.12
as of June 2010 and is accompanied by other fairly extensive mods, so I
doubt it could be easily ported to the latest and greatest motion.
Be glad to share if anyone is interested in trying.? FYI, functions of
the other mods are:
1. Asynchronous DB transactions, so motion doesn't miss frames waiting
for a remote DB commit.? Useful for rapid off-site logging of motion
events; I presume competent burglars will snag the motion server within
1 minute of a break-in.
2. Prepared SQL statements and binary transmission to minimize DB
session bandwidth and load.
3. An on_event_end_sql option plus several new mystrftime() substitution
symbols to allow shell or SQL stored procedures to figure out what to do
with motion vs. PIR alarms.
4. Change on_camera_lost event to on_camera_change (loss/gain/stop) and
add an on_camera_change_sql option to allow camera loss to be logged
and/or begin and terminate automatic recovery (e.g., bouncing power to
the camera, possibly more than once).
5. Multiple SQL statements per camera thread (presently 3: new
image/video file, camera acquired/lost/stopped, motion event end/summary).
Most DB-related mods are implemented only for PostgreSQL.
Contact me off list if you want the code ...

Hi all,
installed motion on Ubuntu18
I can see both of my two network cameras using VLC. they are old cams
but working.
I have attached copy of motion.conf
rtsp://user:password@10.0.0.78/11 {tenvis 1p391w or similar(no further
info)camera}
rtsp://user:password@10.0.0.90/onvif1?? {sricam SP007 or similar(no
further info on it)camera}
I used camera1-dist.conf file for both, modifying name ,id and netcam url
to create camera1.conf and camera2.conf.
Problem 1 no local host view.
I ran,mark@fatcat:~$ motion

The mkv is indeed in my local dir and is capturing images as expected.
But yet when I go to web browser(firefox) localhost:8080 it says no
cameras running. I expected to see a live view?
Problem 2
camera 2 the onvif1 errors with
/Unable to open camera(MyCam2): Invalid data found when processing input
/not sure why its works from this url in VLC.
thoughts?
