IR FUNCTION (Removable IR Blocking)
The IR blocking filter enables the PTZ Camera to capture a clear image at night time
or in low light conditions. During the day, the IR blocking filter is fitted to block the
infrared light and ensure a clear image; at night, the IR blocking filter is removed to
catch the available infrared rays to view images in black and white. In 23× and 35×
models, the user can view colour images when the IR function is activated. Refer to
