Security internet cameras- which?

[sparkie7]

Just wanted to field around to ask if you are using a web camera/video cam in your home/work place for security reasons and to safeguard and watch over your Macs and other valued possessions. Which are you using and would recommend. Pros/cons?

What are the features to look out for. I found this one below but wanted to get an idea of whats the best brand/model currently on the market.

Thanks
