I spend a lot of work to integrate two of my three cameras into my home alarm system (they now start up when activating the alarm with a home build relay) and now I understand this its not going to work. It was supposed to send me mail (and it does) if there was someone coming into my home. Well  It sends a lot of mail all the time. As soon as the light changes it send pictures.. This really sucks and its not a "motion detection" worth the name.
Have to throw away all my three cameras and buy something that works and send mail or something when something moves instead. I'm  really disappointed

You might want to consider getting a hosted website account, some like 1and1 are not terribly expensive. Then you can have the camera ftp the images to the server, and view them off the server. That's what we do - because shifting light, especially on a foggy day, can generate as many as 200-300 images per half-hour. Of course, we have to delete the images over a week or two old to avoid overfilling the site quota.

The amount of mails are not the problem for me, i have a lot of space but thanks anyway for the advise. No the fact is that I only want mail when someone moves in front of the cameras.... but I guess its not possible. Should have done some more research before starting the whole thing.
Wonder if there is any camera  detection system that work as a ordinary alarm detection usually does?

Whats Dlink enginers thought of when making this motionsystem I do not understand. When and were can I use it.. I cant see any reason why they ever made it!!!  and called it "motion-detection"

The problem is that the cameras don't detect motion in its true sense. They detect Changes between the last image and the current one. Images that differs more than your specified threshold is reported as movement... even if they are strictly not movement but light changes.

You could try turning sensitivity down a notch, but yes, there will be a bunch of false positives even if I have managed to get them down to acceptable levels.

I wonder if there is a way to ask the camera for images manually... if there were then it would be possible to create a motion detection feed by making a program of your own and simply ignore changes that occur equally across the screen.

DCS-932 - Motion Detection Settings

As the last poster pointed out, the DCS-932L looks for pixel differences in adjacent video frames. If the pixel difference surpasses the user-defined threshold, a motion detection event is triggered. Newer DCS models employ passive infrared (PIR) for motion detection, which uses heat differentials for motion detection triggering. PIR is more accurate than the traditional pixel differential approach.

PIR..okej. then I have to at least check it out.
Have been on ebay and found some hd ip cameras there for reasonable price but its just this PIR I am looking for. Thanks..

My prior post also included a link to another thread containing recommended DCS-932L settings that improved motion detection for many users. You may want to take a look at that thread to see if that helps your situation.

Yeah for true motion detection you will want a camera with a PIR sensor. Any camera with "motion detection" without mentioning PIR will be software based that will only detect movement as in the amount of pixels that have changed between frames. If you turn a light on or off, it will trigger an event.

Also higher end cameras will have DI/DO interfaces as well if you are more serious surveillance. The DCS-930/932's are great affordable nanny or pet cams for viewing what's going on when you're away but that's about it.

I did try other settings but i doesnt work when the camera dont use PIR. Its very important that it just works when a person activate it. My house alarm wont work other vise.

But anyway. I did see that it was to bad pictures to really use to identify somebody so I have to have other cameras anyway.
