Questions · Cameras
Infrared or white light?
Infrared if there can be no visible light in that place, and white light whenever you can, because with white light the image comes out in colour and colour is half the identification: the colour of the car, the colour of the jacket, the logo on the van. In infrared all of that is grey.
White light also has a deterrent effect that infrared does not, and it has the matching drawback: it bothers the neighbours, and many councils have light pollution bylaws limiting what can be pointed upwards and at what hours. Worth checking before designing a façade full of floodlights.
The combination that usually works is permanent infrared so there is always recording, and white light that comes on only when something triggers it. You get the colour at the moment that matters, you save power and you avoid the neighbour's complaint. Many cameras carry both, plus a relay output to drive an external floodlight.

A written answer is enough to decide whether it interests you. To know whether it works at your site you have to see it on a real scene, with the image as it is and, on top of it, what the system understands from it. That is on the IRIS Neural website, which is the group's product.
