Using Web Cams With A VMS?

I have not tried web cam with vms, but I did some testing with Opencv and Ffmpeg. They are design for close up. Non HD web cam becomes blurry around 25+ feet. HD web cam like Logitech C920 can extend that up to 40 feet.

If you need to identify people in the recording, you have to be careful with distance from web cam to subject.

Another issue is usb cable length. I believe you run into issue after 75+ feet long, but I have not tested this limit yet.

One of the "old timers" motto in our office is "a camera should be expected to do only one job a time". When you try having a camera do different jobs, problems can more easily occur. Can you jury rig something? Probably. Would it be worth it? Most times I think not, since you may have to have 2 or more system components in the middle to get your end result. Since you seem to be seeking general advice and not just or necessarily a technical how too, my advice is unless the camera has some built in universal compatibility, like network streaming to both your web servers and the VMS via ONVIF or HTTP streaming, for example, it would probably not be worth the trouble to jurry rig something. If that's the case but you like what the web cams are looking at and want to record them to your VMS, probably better to put seperate cameras for that purpose.

Absolutely you can bring them in to your VMS Cynthia. I am thinking you would not have to rig anything and can just slap the ip into your VMS. Obviously there is a bit more too it, but if ALL you are looking for is to take the same feed and record it you should have little issue getting it set up. We have taken advantage of a few Axis cameras that other departments use as an eyeball into their areas by putting the feed into our VMS. Works out great, but you need to be aware of the bandwidth implications because the last thing you want to do its overload the network and cause their camera feed to fail. If that happens you would be cut off in an instant and probably never get the opportunity to try again.

OnSSI NetGuard EVS is extremely old. You'll have to find the make and model of your "web" cameras and see if they are compatible with NetGuard.

As long as the website only pulls one video stream and then the web server handles the multiple requests for that camera you should be fine bandwidth wise. One stream for the webserver, one for the NetGuard server.

It looks like they are all StarDot cameras (at least 3 out of 4), and as far as I can tell, the model is NetCam XL VGA. They have odd IP addresses such as 216.174.20.198 (feel free to view the feed).

The StarDot web site suggests that video from these cameras is recordable, but I don't know if they can stream to the web and record to a server. Most of you are a million times more savvy than I about this sort of thing, so if anyone has an inkling, please let me know.

These cameras are recordable from any VMS that supports RTSP. I have tried your link and running it through VLC to test.

At home, I am currently using 4x 7MP web cams as a makeshift security system using two small laptops (netbooks) running "iSpy" I think...

One netbook covers the front yard/driveway/front door area and the main entrance to my home, the other netbook covers the backyard/back room/rear entrance of my home. I have two netbooks due to cable legnth limitations of USB cables. The image quality is so so, low light looks like garbage, but it meets a few of my simple needs, keeping an eye on my dog and kids.

Now if I had the money to spend on a real wireless IP camera system....
