I think I found the gear that was mentioned in the #372 podcast while I was wandering the aisles at Fry's today. It is called wilife, http://www.wiflife.com, otherwise known as LukWerks. It is a video recording system that claims to be simple to install. It offers internet viewing and email or cell phone alerts if a camera detects motion. There is a catch however, read on.
One plus, but a feature that adds a lot of cost, is that it uses power line carrier technology to connect the cameras to your PC using Ethernet. This is an advantage in that you do not have to run wire from every camera back to your PC. You hang the camera and plug it into the nearest outlet to obtain power and an Ethernet connection. It does increase the cost however, by my guess, about $80-90 per camera over a hard wired camera. This system has garnered a lot of good press from PC Magazine, WSJ, Forbes, etc.
Here is the catch, remote viewing is limited to their website and to only 10 minutes per day unless you pay a monthly fee, this according to Engadget. Read the rest here. http://www.engadget.com/2006/01/15/lukwerks-video-surveillance-in-a-box/. Be sure to read the comments, some folks disagree about the time limit and charges and others have alternative suggestions. Your mileage will certainly vary.
Personally, I would still want good locks and an alarm system, however this system (or any video system) could record any bad guys who break in which may increase the chance of apprehension, unless of course the bad guy makes of with your PC! A decent geek could put something similar together for less cost and no restrictions on viewing remotely. I did as much when my house was for sale. I got an alert when a real estate agent entered the house, and then a few well placed cameras allowed me to observe them remotely.
