measurenoise is a tool for determing the 'noise threshold' for tools like motion. It uses v4l interface.

Installation for measurenoise:

Get the colorconversion routines from:
http://www.smcc.demon.nl/webcam/release.html#ccvt
build them and copy ccvt.h and libccvt.a to the measurenoise source-directory. Then:
make install

Usage:

measurenoise
or (e.g.):
measurenoise /dev/video1

Do not use the average noise threshold directly: measure it for both dark and light situation and pick the highest value. Then, add 1 or2. Furthermore: first set your device to the same parameters you use in the package with which you use this noise-threshold. E.g.: framerate,
width, height, etc. Also very important is that you point the webcam to something static: there should not be anything moving! For that, you can use dov4l: http://www.vanheusden.com/dov4l/
