JVC not only satisfies customers’ current demands but also
anticipates their future requirements by incorporating advanced
camera technologies inside the TK-C920U(A) high resolution,
color surveillance camera.
The camera performs brilliantly in all the key areas. 540 TVL
resolution is delivered by the 1/3" Interline Transfer CCD. The
quality of key image parameters are continually optimized by the
intelligent Digital Signal Processor. At 0.48 lx in B&W mode, the
Easy Day/Night Function allows the camera to achieve high
performance even in low light situations.
Easy Day/Night Function
The TK-C920U(A) 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.
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 540 TV lines horizontal resolution combine with high-quality
performance.
1/3" High Resolution IT CCD with 380,000 Effective Pixels
JVC’s TK-C920U(A) 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-C920U(A) provides dual-edged detail correction — horizontal and vertical with 2H line
memory.
Super LoLuxTM and Automatic Gain Control (AGC)
As the ambient light level falls the AGC seamlessly increases the camera’s sensitivity.
With Super LoLuxTM turned on the AGC will further increase the camera’s sensitivity to 0.7 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.
