These sophisticated colour surveillance cameras incorporate
advanced features for enhanced identification capabilities even
at night in low light conditions. From the moment you power
a JVC camera, you experience true picture reproduction.
Easy Day/Night Function
The TK-C920BE and TK-C921BEG automatically use colour mode when the subject is
bright, and B&W mode when it is dark. In B&W mode, AGC is always active to achieve
high performance even in low light situations.
Focus Adjustment Function
When the focus adjustment function is turned ON, focusing is conducted with the lens
iris fully open for about 30 seconds before returning to its original position. This results
in a shallow depth of field (high-speed shutter) and simplifies focus adjustment.
Display Mode CRT & LCD
Images of the required brightness can be obtained by selecting the appropriate display
mode both for a CRT monitor and LCD monitor.
Built-in Revolutionary Digital Signal Processor (DSP)
JVC’s innovative Digital Signal Processor automatically adjusts camera parameters to
ensure that sharp and natural pictures of 550 TV lines horizontal resolution combine with
high-quality performance.
1/3" High Resolution IT CCD with 440,000 Effective Pixels
JVC’s TK-C920BE and TK-C921BEG come with a 1/3" Interline Transfer CCD for
accurate colour reproduction and signal-to-noise ratio of 50 dB.
Detail Corrections — Horizontal and Vertical (2H)
The TK-C920BE and TK-C921BEG provide dual-edged detail correction — horizontal
and vertical with 2H line memory.
Super LoLux
TM
and Automatic Gain Control (AGC)
As the ambient light level falls the AGC seamlessly increases the camera’s sensitivity.
With Super LoLux
TM
turned on the AGC will further increase the camera’s sensitivity to
0.35 lx at F1.2.
Manual or Automatic (ATW) White Balance
For flexibility of operation in a wide range of environments the white balance can be set
manually or can be automatically adjusted in real time by the Automatic Tracking White
Balance function over a range of 2,300K to 10,000K.
