The system from a hardware point of view is really amazing for the price. Connecting things up is pretty intuitive; worked right out of the box the first time. Night vision works for limited distance; to be expected. Connecting to the internet was done with a wireless bridge in client mode; again without an awful lot of pain. Sounds pretty good so far.The bad.Instructions when needed I am guessing are Chinese converted to English. Very choppy wording and a bit of a struggle at times to understand. There doesn't seem to be version levels on the written material in what is supplied and what is on the internet; a lot of the stuff is back level and no longer correct as you discover by trial and error. This matters when you try to get some of the software working. The event mask and event record doesn't seem to work. You get event history, but not in the area that you picked for trigger. I never could get the ""send me an email"" software to work and I did put a lot of time in on it. Support for the US is not covered with a toll free number and I believe is good for just 4 hours daily. In all fairness I haven't yet tried it. But for $150 it's not bad!
