Hello,
I don't know whether it works with your camera, I use a Raspi Cam in Night mode.
At night the shutter can take up to a second so that the max Framerate
can be 1 fps.
To change only one parameter one of the others should answer, they
have probably already done that.
I have 2 config files, with separate fps, mask noise, threshold and so on.
For a test, switching it depends on which user motion starts.
If a standard user does, you can use crontab.
Use crontab -e and put this at the end:
0 6 * * * killall motion
1 6 * * * motion -c /your_path//motion1.conf >/dev/null 2>&1
0 18 * * * killall motion
1 18 * * * motion -c /your_path//motion2.conf >/dev/null 2>&1
For sudo use first "sudo su"
and then use crontab -e.
regards
ThomasD

Hi Thomas,
thanks for your quick reply. I can indeed configure the exposure time.
Resulting in a much better image during night time (certainly persons are
still not sharp as during daytime). If there is a way to automate the
javascript process in a script, that would probably solve much of the problem.
Thanks
Rainer

Message-ID: <0b784dd1-8593-49a6-b9ef-3d33b81e4...@arcor.de>

Hi,
I am using an old low res (640x480) camera with a narrow angle lens for a
while now. Because of the bad picture quality I want to change it to a newer
camera with a higher solution.
The new camera has a wide angle lens. So I have a mask file which covers about
2% of the whole image of the camera. I like to use the lightswitch feature of
motion, which works fine with the old camera.
Unfortunately it does not work well with the new setup. I assume, there are two
reasons for this. The main reason seems to be, that for detecting lightswitch,
the diffs of the masked image is compared with the total image size instead of
the number of pixels of the mask.
In addition lightswitch_percent is compared with "> 1" (motion.c line 2244)
which does not allow to set it to 1. Are these bugs or is it intended?
Best Regards
Arvid
