Webcam + Motion Detection/Recording

Hi all,

Really quick question... I've got an older Logitech webcam (that's working just fine) which I was wondering if it was possible to have it start recording if there's motion (or some amount of change/variance detected).

I've got the Logitech Image studio, which really means nothing... is there some program I can run over that (like a screen capturing/fraps style program), or is there any other kind of program that I could pipe this feed into?


Many thanks in advance! :)
 
Oh, you found Dorgem.

There are also some shareware like Coffeecup Webcam and WebcamXP. WebcamXP is probably the most robust with it's multiple cam support and SMS capabilities, enabling you to receive alerts via a cell phone.

I don't know how far you want your cam from your computer, but if it's more than 10 feet you are limited by USB and it's 10 foot limit. "USB Active Extension" cables can boost the signal and solve this problem. I use them and they work flawlessly.

I'm not sure what the limit is for USB 3.0, but I know there's a future tech due next year that uses optical and you can run cable up to 100 meters!
 
Nice, thank you for the input, too!
I'm liking Dorgem, but I wish there was a "capture threshold" or something... It seems to be taking a heck of a lot of photos, but not much is going on. I've got the cam pointed at the driveway (to reduce swaying trees in the scene), but it's still taking caps almost at the interval I've specified (even with motion detection turned on).

Is there any hope?

Also, it's pointing through a standard black screen (on the window), so although there isn't a lot of movement, there's some 'artifacting'/redrawing or shimmering (very very slight) going on... you know how webcams are. Any ideas?
 
G'day :)

Dorgem works if there's very little movement, but it's oversensitive to the flicker in some cheaper webcams.

Yawcam seems to work, but was a little CPU intensive.

Tebocam looks like it works very well, but it's very CPU intensive - 80%+ on my dual core 2GHz system.

.. so the winner for me is iSpy from http://ispy.developerinabox.com/

It's open source, multi-camera capable and worked well in my case with one camera attached to an old laptop, using about 20% of it's CPU to run as a server, with the main computer in the house getting the image wirelessly and recording on motion.

The only concerns are that it hasn't been upgraded since 2008, and that it won't work unless it has an internet connection at boot time.

Those issues aside, the CPU usage is very low on both the client and server ends making this the winner for my needs :)
