I think you mean ICR (Infrared Cut-Filter Removal) cameras

I think that the author means the camera with two different sensor ( of course, there will be two lenses for 2 sensor board). one is colour one, another is B/W one .

 

At visible band, the B/W camera's the sensitivity triples that of colour camera, however, at IR band, it may only 10% or 20% better than colour camera (due to the bayer filter over the CCD sensor, of course, I mean the colour camera without IR cutting filter).

 

Maybe that is why the dual head camera is not so attractive for IR based application.

Dual CCD Cameras, used them for years, the most well known in the industry being the Extreme CCTV's EX82, but now there are others.

Thank you, i'm talking about this, two different sensor.

Cameras with Dual lens have 2 CCD Modules with two seperate lens. These cameras have a noticeable difference.

Does anyone have captures between the day night cameras and these ones for a comparison ?
