A two-in-one solution: a color camera during the day,
a high-sensitivity B/W camera during the night
A color camera, which captures objects in vivid colors in daylight,
becomes a high-sensitivity B/W camera during the night and provides
tiny details even in dark corners. A day/night camera is a two-in-one
solution.
Main Features
• 1/3-inch CCD image sensor with approx. 410,000 picture elements
• Super-high horizontal resolution of 520 TV lines
• Higher sensitivity and lower smear effect than that of the previous
model:
Minimum illumination (F1.2 lens, 50IRE)
VCC-4794
Previous model (VCC-4594)
• New, built-in DSP (digital signal processing) circuitry delivers superior
color reproduction and reduced noise.
• The camera's sensitivity to exposed light allows it to automatically
switch from color to B/W mode.
• Two types of backlight compensation selectable.
Multi-spot metering system:
Luminance is measured
in 64 separate areas for
optimum backlight
compensation even for
peripheral and moving
objects; features select-
able normal and high
modes.
Center-zone metering system:
Luminance measured at center and automatic lens aperture adjustment
enable a clear image even when backlit.
Other Features
• Auto-tracing or manual white balance selectable (Slide SW)
• Internal synchronization, line-lock capability
• Built-in electronic iris for indoor use
