What is a good usb camera for video surveillance?




eHappy


or anything that i can hook up to a computer


Answer
I would not use a USB camera for a surveillance/security camera.

You might be in a different position, but generally, I have found that the camera needs to be pretty far away from the video monitor - in this case, your computer.
http://en.wikipedia.org/wiki/Usb#Maximum_useful_distance tells us that USB cables cannot be very long. As well, most web cams do not have "night vision".

Contrast that to the 70+ foot CAT5 or coax cable runs I have connecting different analog surveillance cameras feeding into a security DVR that is on the computer network so I can see what they see through my computer...

If you can't use a security DVR, you can get cards to install in your computer that can use that video, too. Check Frys.com... Electronic Components: Security: Closed Circuit Television: recorders: there are standalone recorders for single or multiple cameras and PCI cards for computers with available expansion slots.

Since you did not tell us which computer, we don't know if this will resolve your issue.

I bought a wireless 4ch DVR Security Camera system?

I bought a wireless 4ch USB DVR Security Camera system from eBay. But after all I got a camera system I didn't want.

Because it does not record all four cameras at the same time and can't hear the sound from the mic of the cameras.

SO I am wondering If I can use another receiver/dvr software on the wireless cameras to record all four cameras?!

(btw I have Windows 7-64bit)

Please take a look at the cameras from eBay.

HELP! :(



Answer
If you know the manufacture of the camera look for their homepage on the net and then give them a call. They should be able to help you.
