I really like these cameras and the software they come with. Can't really beat the 720p res you get from these cameras for the price. Installation was a sinch (one cable pretty much and you are good to go). And it's a sinch to add more if you need. I installed these at a school that had the network already in place. Just had to run a bit of CAT5 and we were up and running in no time. The plastic casing seams a little cheap but I haven't had any issues with them yet.
