Network cam all black triggers event
I have 6 DCS-900 network cameras. Several times per day, a few of them (not all at the same time) decide
to return a completely black image (unknown why, camera hardware bug???). The image is totally black.
This is NOT your gray image when connectivity is lost. Connectivity is good, pings OK, and within 30 seconds
or so, normal processing and normal images start to work again. When this black image is returned by the
camera, the motion detection logic notes this as a motion event and starts high-speed recording. When
the correct normal image eventually does appear, the box (because of option "locate on") is drawn around
then entire image (where it used to be completely black). BUG ?? If you see that an image is totally
and instantly completely black, maybe you should continue comparing and NOT declare it as a motion event
if the picture soon returns to normal. Comparing the last pre-black image with the first post-black image
would show that no motion had occurred. I think of this as a bug since it falsely triggers this as an event.

. Your motion config file is always an important part of a support request because there are so many options to change.
