I have personally used Speco's HT-INTB8 Cameras on many occasions and the only thing I can say is they are great if you set them up correctly. If you don't know a lot about CCTV cameras you might have problems understanding exactly how to configure them and should probably revert to using a camera with less settings.
By the way, I'm not sure if you guys new ADI stands for Ademco Distribution Inc. I just found that out the other day and was shocked. I had no idea. lol
