HighlightCam.com is a very good site if you are interested in basic video surveillance. You can easily set up a simple security system using your existing webcam. The key features include
– motion detection
– email alerts
– free and paid levels of service
– reduces hours of video into seconds containing only the important bits
– view videos from any internet connected computer
The free version of the service is quite worthwhile. The main advantages to upgrading to the paid version, currently $8.99 /month, is that it gets you video storage for 2 weeks (up from 24 hours) and the ability to download recordings. Other than that you also get no ads (they are unobtrusive anyway) and higher resolution video.
HighlightCam is definitely worth checking out. I use it to monitor my home when I’m out of town.
