# presence-detect.sh mirrors the real webcam into this virtual device so its

# 20s-interval motion checks never contend with other apps (Zoom, howdy, ...)
|
|
# for exclusive access to the physical camera.

|
|
# video_nr is fixed so the device always lands at /dev/video42, regardless of
|
|
# how many physical webcam nodes (including UVC metadata nodes) get enumerated
|
|
# first at boot.
|
|
#
|
|
# exclusive_caps=1 makes the device report standard single-purpose webcam
|
|
# capabilities, which most capture apps (ffmpeg, OpenCV, browsers) expect.
