Hi Folks!
Having problems figuring out how to use masking options.
Hardware: Raspberry Pi 4, Bookworm, Wayland (probably the Labwc option ?
I don?t know [yet!] how to test for that). ELP USB camera:
ELP-USBFHD06MT-KL36IR lsusb: ID 32e4:9230 HD USB Camera.
Motion software is Version 4.7.0.
There is a ceiling fan along with tree and shadow motions with are
giving a constant series of recordings. I can?t reposition the camera to
get the fan out of view because of position between window glass and
mini-blinds.
What I have tried so far:
In /camera1.conf/ first added
*smart_mask_speed 5*
Didn?t seem to make any difference.
This afternoon commented smart mask and tried
*area_detect 789*
so just pays attention to the bottom portion. Still picking up a lot of
moving shadows from the trees so probably not my best option but again
not seeing any changes in sensitivity so tons of recordings.
Thanks for pointing me in the right direction!
Barry

I never found smart mask to work reasonably. Eventually with some
wind it seems to mask out almost everything.
And the area_detect I think only works for events.
You need to make a mask file. Take an image from the camera, read it
into gimp, then paint everything black you want ignored, and white you
don't want to ignore and export it as a binary pgm.
file should look like this:
file gs2_mask.pgm
gs2_mask.pgm: Netpbm image data, size = 3840 x 2160, rawbits, greymap
And have the same size as your camera image.
Then add to the config file this line:
mask_file /etc/motion/gs2_mask.pgm
I have to adjust mine and/or prune trees getting into the edges of the
images every so often.

That would be bad!

I couldn't quite tell:? "Detect motion in predefined areas (1 - 9) and
when Motion is detected in the area, execute the script." Scanning
though the section? I wasn't sure what script was being referred to

<chuckle>? That's why smart_mask sounded so good!? ...I'll try creating
a mask and get back with the results.? Thank you!
