Stop Your Losses — Capture All The Details With JVC's 550 TVL
CCD Advanced Surveillance Cameras!
These sophisticated color surveillance cameras incorporate
advanced features for enhanced identification capabilities even
at night in low light conditions. Reduce your risk today – with
surveillance that never sleeps. From JVC.
Easy Day/Night Function
The TK-C920BU automatically uses color 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.
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 380,000 Effective Pixels
JVC's TK-C920BU comes with a 1/3" Interline Transfer CCD for accurate color reproduction and
signal-to-noise ratio of 50 dB.
Detail Corrections — Horizontal and Vertical (2H)
The TK-C920BU provides 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.
