I would like to install a camera (wireless if possible) near my front door that would connect to my PC or Ethernet connection (cable modem) and allow me to do two things: 1. Monitor the video feed via my PC at work. 2. Save the footage to my PC hard drive. Has anyone here installed something like this and how much does it cost? Would something like this be what I want?: http://www.smarthome.com/6325.html Thanks!
