Motion Detection appears to be completely random
« on: July 11, 2012, 06:41:13 AM »

So how is the Motion Detection supposed to work?

No matter how much I try to adjust the sensitivity or select the areas to monitor, the thing either doesn't capture anything or seems to capture utterly random stuff. Most of the images captured don't have anything moving at all in the supposedly selected areas, some don't have any motion at all and real motion is mostly left uncaptured. Things just suddenly change places between those captured series of no motion.

I've set the device so that it uploads the pictures to FTP server when motion is detected, disabled audio and set video to 5 fps, though I think these shouldn't matter(?)

I've tried various levels of sensitivity and tried to select areas expected have the motion to trigger, also tried to invert the selection. On some variation of these I get a lot of captures, on others I get none but regardless of the amount of captures, their relevance in respect of the motion doesn't seem to have any correlation to setting changes.

I'm stumped here, have I done something wrong or is the motion detection really this sucky?

If it is useless, is there some external Win/Linux software available that would do the trick? D-ViewCam is not an option as I don't really see any real reason for a (network) camera software to require admin privileges and disabling UAC to work...

Hi,

Thanks for the instructions JavaLawyer. I had previously only tried higher sensitivity ranges but I followed those instructions and started with low sensitivity  (5%) and slowly worked my way up to 85%.

Sadly, the outcome was the same as with my earlier attempts. I either didn't get anything, or I only got random short clips without any apparent movement, and this time I failed to get it to capture any real motion. I wouldn't mind these "false positive" captures so much if I got the real deal as well.

But since I apparently won't be getting those relying on the firmware based motion detection, another solution that would work for me would be an external software that would monitor the camera and perform motion detection out-of-device. Any tips regarding these?

Or, if someone was aware of a third party (open source) firmware project for the device, I'd be interested in that as well...

I am not aware of any third-party alternative firmware initiatives. However, here is a link to a current list of third-party software that plays well with the DCS-932L: DCS IP Cameras - Compatible Third Party Applications to Monitor Video.

You'll have to investigate these products for any on-board motion detection functionality.

All right, I'll look into those.

Thank you, cheers.

I think I saw a thread (somewhere) discussing a web-based app that "may" have motion detection built-in.  I'm monitoring so many boards that I may be confusing this with an unrelated topic.  Try performing a search...  :-\

Use mouse to click the blocks where you want to monitor for motion

Alright, programmer of the webUI. And if you have click on this blocks and later want to change the motion detection. You must remember if you has click the blue ones or not :) 

Her a free tips to new text:

Use mouse to click the blocks where you want to be blue for for motion detection.

Pleas D-Link.

I believe this FAQ post describes what you are referring to: DCS-932L - Motion Detection Settings
