CCTV Operator Interview Question:

Tell me how Do I Set Up A Camera And Lens For Use In Low Light Conditions And Or With Infra Red Lighting?

Submitted by: Muhammad

When setting the back focus of a Color camera for low light conditions you should place an ND1 (Neutral Density) filter in front of the lens. When setting the back focus of a Mono camera for low light conditions you should place an ND3 (Neutral Density) filter in front of the lens. When setting the back focus of a Mono camera fitted with I/R lighting for low light conditions you should place an IRP (Infra- Red Pass) filter in front of the lens.
