Set-up of the camera is made simple via the intuitive on-screen display (OSD). With a choice of vari-focal lenses with a low f stop of f 1.6, ensure greater sensitivity in low light conditions, whilst the IR corrected lens with moving IR cut filter ensures that the 23 in-built LEDs are linked to the IR cut filter so that the camera switches to monochrome at the same time the LEDs illuminate. The filter delay feature is adjustable to ensure the camera will not switch on or off during momentary reductions or increases in lighting levels. The cameras also have the ability to be manually switched to monochrome mode with the LEDs on. This is useful in dimly lit areas where it is important to continually light the immediate area.
