Motion Detection triggers unexpectedly
Changes in luminance
Motion detection is based on changes in luminance in the image. This means
that if there are sudden changes in the lighting, motion detection may be trig-
gered mistakenly. Lower the sensitivity setting to avoid problems with lumi-
nance.
No audio
Incorrect setup
Check the sound card in the PC. Ensure that the mute button is not pressed and
