Digital slow shutter
Allows the camera a long exposure time of 1/2 sec,
which translates into a higher sensitivity and
minimum illumination of only 0.1 lux. Since more
colour data is captured and stored by the camera,
colour accuracy is greater than a conventional video
camera.
Metal frame and easy installation
Compact solid metal frame allows you to install it in
the casing of your choice. And all interfaces, including
power, are integrated into one connector.
Built-in optical power zoom lens
Highly reliable and offers auto focus, auto iris and
zoom functions, letting the user monitor a scene from
any angle of view. In conjunction with X8 digital zoom,
the total zoom ratio is X176.
High resolution
1/4 inch CCD pickup features approx. 440k effective
pixels and high horizontal resolution (460 TVL)
means picked-up images are reproduced with detail
and clarity
AI (Artificial Intelligence)/Fuzzy Control Circuit with DSP
AI Auto Iris adjusts iris so that video output is kept at
a fixed level, even if surrounding illumination changes.
AI Auto White Balance provides natural colour
reproduction according to ambient lighting.
Backlight compensation
Even with strong incidental light, a backlight
compensation area can be selected from six divided
areas on the screen so that the subject will not be
too dark.
Remote control through RS-232C
Allows control of the camera’s focus, iris, zoom,
shutter, speed etc.
