I installed the slightly earlier version (no smart phone access) of this system in our 2nd home in December of 2008. It seems that many people post reviews soon after purchasing a product or very soon after something goes wrong with the item or the service. I thought it might be good to post a review from a long time user. 

I had some trouble with system set-up (It ended up being a problem with my computer). And, I had to replace one camera about a year ago. The customer service was responsive and helpful. We view the cameras daily from our home 900 miles away, and we've used them to resolve a couple of false alarms with our ADT system. The cameras have been operating outdoors in TN for over 2 years in temps between 5 and 100 degrees in rain, snow, sleet etc. I have recommended this system to many people and will continue to do so.
