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.

Is video surveillance camera technology stable?

Strange question but I want to buy a video camera detector. Even stranger huh... I found out about these devices recently. It is a device that detects wireless video cameras that are monitoring you like in elevators, gas stations, banks and (I want to find out where else). These detectors have a video display [cool] and actually show you the vision of the surveillance cameras so you can find out where they are mounted. The trouble is, these detectors cost about 500 bucks so if the frequency range of the wireless monitors changes the detector will be obsolete and worthless. NOTE> This is not going to be used for terrorist activity so don't go thinking you will be a hero to report me to the feds. You may wonder why i would want such a toy but i am just extremely curious who is watching me and then i might wonder why. I remember speaking freely at gas station pumps and the cashier would be listening in on the conversation which i do think is totally illegal to do if not related to gas.
Answer
It would not be worth buying the equipment you are talking about at the price mentioned.
1) Most important institutions such as banks, gas stations etc.. do not use wireless cameras because of the costs, reliability & security problems. Where wireless cameras are used at important locations, these video signals are most likely encrypted, therefore a viewer would not work.
2) Most wireless cameras available to consumer market operate in the 1.3 or 2.4Ghz frequency range. In general, there are only four channels available. So if you buy a cheap wireless receiver for a wireless camera with switchable 4 channels, then you would be able to receive the wireless signal from most general wireless cameras. And this should cost you less than $80 for the whole kit including a camera.
3) Dont forget that newer IP cameras can be wireless which are used in important places, but the video from these cameras can only be seen on a PC within the network that the camera is connected to.
4) IF you really want to be able to connect to any wireless audio or video device and it means that much to you, then try the expensive device but I dont think it will deliver what you expect .
