Motion Detection
« on: July 31, 2013, 04:57:13 PM »

I'm still in the process of fiddling with my two new cameras: DCS 2132L and DCS 7010L. 

I have set them up to continuously record to an Apple Time Capsule and to record video to their respective SD cards when motion is detected.  I also have them set up to record the log file to the Time Capsule every hour (I figured this was the best way to work out which of the hundreds of videos I should look at if an event happens).  When I review the SD cards, via mydlink, I have noticed that there is a (brief) recording every minute, even during the middle of the night when the house is still.  Reviewing these I can see no suggestion of any motion in the clips!  Have I got the sensitivity too high?  The 2132 (in the house) is at the default of 85% and I have turned the 7010 (garage) down to 75%.

To be honest, I am on the verge of turning off the SD card recording but have left it for now as it sounded like the easiest way to view footage of anything that happens in the house whilst I am away.  Accessing the SD card via mydlink should be easier than remotely accessing my Time Capsule and then trawling through all those videos.

Yeah, 85% is probably too high. 

Why not turn off motion detection, and use PIR motion detection only?

I turned down the sensitivity (75% I think) and it is working better.  The 2132 has PIR but I don't think the 7010 does.  I think the problem is that, in the dark, the pictures become very grainy and the camera sees that as motion.

On my DCS-2132 I noticed that too high gain will give too much static and trigger the events. So one nerd to edit gain to get less noise. Sensitivity helps too, but too much gain might force the sensitivity too low for reliable detection... You'll lose some dim view, but that can't be helped: the sensor and gain static just doesn't allow reliable results. If your detection target is obvious, like detecting a light bulb, then sensitivity limitation should not be a problem....

Is there a low noise setting in image setup on the 7010l?

The 2132l shouldn't although I'm not in the latest f/w.

The 2230 does. . Really cleans up the image,  but need to reset back to auto during the day.
