Progressive Scan CCD Image Sensor
The VK-S454R/S454ER has a high-performance 1/4-inch progressive scan CCD.
Wide Dynamic Range
A wide dynamic range is achieved by the progressive synthesis function, which records an image at
a shutter speed suitable for brighter object and another image at a shutter speed suitable for darker
object, then and synthesizes the two images, thereby reproducing a clear picture.
Removable IR Cut Filter
The IR cut filter that is fixed on other video cameras can be detached in low illumination. Removing
the IR cut filter in low illumination will make it possible to use the infrared rays as a light source, so
recording even in 0.02 lx will be possible.
Built-in Optical Power Zoom Lens
A highly reliable optical 23-power zoom lens is mounted, and it is equipped with auto-focus, auto iris
and removable IR cut filter functions.
12-Power Digital Zoom Function
The 12-power digital zoom, combined with the 23-power optical zoom, makes possible up to 276-
power zooming.
Remote Control via RS-232C
Focus, iris and zoom can be remotely operated via RS-232C.
