Superb Picture Quality with
EXview HAD CCD
The adoption of Sony EXview HAD CCD technology
improves basic camera performance. For example,
these cameras offer superb sensitivity of 1 lx (typical),
and a low smear level and D-range.
RS-232C or RS-422 Serial Control
(VISCA Command)
All camera settings and pan/tilt/zoom functions can
be controlled remotely via a PC. With the RS-232C
connection, maximum cable length can be extended
to 15 m (50 feet), while the RS-422 connection
extends this further to 1200 m (4000 feet).
Auto ICR (IR Cut filter Removal)
Function
Fig. 2
The Auto ICR function automatically switches the
settings to attach or remove the IR Cut filter for
increased sensitivity. With a set level of darkness, the
IR Cut filter is automatically disabled (ICR ON), and
the infrared sensitivity is increased. With a set level of
brightness, the filter is automatically enabled (ICR
OFF). The ICR automatically engages depending on
the ambient light, allowing the cameras to be
effective both in day and night environments.
Alarm Function and AE Spot Setting
These cameras provide an alarm function that can
detect changes within a user-designated area of an
image.* When a change in AF, AE or both is
detected, these cameras output an alarm trigger
signal to the external equipment via the VISCA
protocol. In combination with the Spot AE function,
these cameras also detect changes in the luminance
level, and they output an alarm signal. The detecting
area can be applied to any of 16 vertical and 16
horizontal blocks. (see Fig. 3)
*
Using any of the pan/tilt/zoom functions will disable the
alarm.
