Can I use a webcam for surveillance outside of my house, What would I need to set this up?

A company called X-10 makes some excellent gear for this application at a reasonable price. A lot of this gear is being sold on Ebay.

You can use an old PC and a router, and either use logmein.com (free version) to access the webcam software remotely, or make a free stickam.com account, and broadcast it live.

Take an old pair of sunglasses and tape it over the lens.  Not very elegant, but it works well on my cheapie Hercules classic silver which previously showed nothing but a white blur when pointed out the window in bright sunlight.  For best results I set the brightness, contrast, and Exposure to the minimum setting and the gamma to max.

yeah it can work but it will not record unless you have a video recorder on this. Mine only takes pictures i'm trying to find out how to take videos but yes. Everytime you leave the house you can record. Just get an extension usb cable and you can take it as far as you can.

I use Active WebCam by http://www.pysoft.com
is cost about $60 but works for me on VX6000
and other usa camera also
