The thumbnails are put in the Stills directory. The line with the "convert" command is the one
Also I am getting a lot of false detects. I have the camera in my kitchen and in the detects I keep getting there is no noticeable motion. The only thing I see is very faint light changes. Can someone explain in noob terms changing the motion settings to get the appropriate detection.
Be sure the camera is not sitting on a surface subject to vibrations or some disturbance. If you have
to you can reduce sensitivity by setting the Motion->Vector Limits higher and you would have
If I go wander around in front of the camera instead of getting one long video of me I get several short videos with different portions of my wandering. I have the motion gap setting at 5 and from what I understand in reading the file this means if it continues to sense motion within 5 seconds it will continue to record the same video until it does not sense motion for 5 seconds and then it will end after whatever setting you have set for post gap. Am I correct?
Yes, but whatever is causing the false detects may be interfering with getting successful re-triggers
to keep the motion detect going. To debug what is happening, turn on the showing of Regions and
Vectors and watch the screen. It may take some time but if you are getting false triggers there
should be some action on the screen. If you see sharp edges (door frames, counter top edges)
with flashes (those are the motion vectors being drawn) it's probably a sign that something is vibrating
the camera. If you see distributed "sparkles" all over the screen it could be the lighting is at a dim
level where the camera produces noise. If you can point the camera at a part of the kitchen
you don't mind people seeing, turn on showing of Regions and Vectors and post here one of
false detect jpegs that is emailed to you. It might give a clue.
I don't understand at all what vectors are. I assume the regions are simply to highlight the areas you want it to detect motion and it will not look for motion anywhere else.
Yes about the regions. The vectors are the information that the camera hardware generates
about how groups of pixels in the video may have moved from frame to frame. They are called
vectors because the information provides the direction and distance for the move.
