a.saji, I used to cover machine vision for another publication, and noticed that Cognex was one of the few camera makes who seemed to consider more than just the camera and what it's immediately attached to. That said, I've also heard complaints like Jim_E's about their barcode readers.
I have to hand it to Cognex, especially the marketing department as they really know how to brag about their products. I've used Cognex cameras with great success for image analysis and their software is first rate. Very easy to setup for pattern detection and other stuff.
That said, their barcode reading isn't that great, regardless what they ads might say. We had them come in and demo a system and it was going to take four of their expensive cameras to cover the field of view to read what we needed, and they still had some problems. I'd trust a more experienced barcode reading company for serious barcode reading. (I used to work for one, so I feel justified in saying this....)
And, I wish that they wouldn't email me so many stinkin' ads. I get more marketing emails from Cognex than any other controls related company!
