I bought the Blue Iris program a couple of months ago, I think it was about 50 bux for the online download. I already had a DLINK TPZ camera that I was playing with so I linked it with the Blue Iris easily and let it do it's thing for a few weeks.
Then I started to look at cameras and found I can spend anywhere from 20 bux to 3K for an HD camera. SO I did an experiment. I bought a Cam for $22 from amazon, I screwed with it for a few days and never got it to hook up with its own program or the Blue Iris, so I tossed it in the trash and bought a Lorex LNB3143B-W. The BLue Iris system found it and linked with it no problem and it works very nicely day and night.
There is a very long story to go with the Lorex camera, but to shorten it out. I bought the Cam about 6 weeks ago, it came in with a cracked lens over the IR bullb array, they were very friendly and helpfull, but don't seem to understand English very well, so it took about 5 weeks of comunication to get them to send me a new Camera, it's supposedly on it's way now. Believe it or not I'm not unhappy with them sofar, I truely think they just have problems with the language. (we'll see). In the mean time I do like the Camera and the Price,$135 so I ordered another.
