I own and like this: Amazon.com : CMVision CMVE-IR15 Wide Angle 60-80° Power LED IR Array Illuminator 200-300' Long Range with Free 12VDC 3A Power Adaptor, 15 Piece : Motion Detectors : Camera & Photo and it is super bright. 3amps and 12v. i see this for sale: AXTON Smart AT-8S-A 60° Infrared Illuminator AT-8S-A.8SA2860 i am happy with my CMVision. but technically speaking, what is the major difference? the one i own is cheap and strong. the expensive Axton appears to draw less amps. does Axton use far superior LEDs? why are the Axton's so much more?
