JVC’s revolutionary 535 TVL CCD and leading edge
DSP technology combine to meet future market needs.
JVC not only satisfies customers’ current
demands but also anticipates their future requirements by
incorporating advanced camera technologies inside the TK-C920E
and TK-C921EG high resolution, colour surveillance cameras.
The cameras perform brilliantly in all the key areas. 535
TVL resolution is delivered by the 1/3" Interline Transfer
CCD. The quality of key image parameters are continually
optimised by the intelligent Digital Signal Processor. The
Super LoLux function allows the camera to achieve reliable,
high performance pictures even at light levels as low as
0.7 lux (using an F1.2 lens).
Built-in Revolutionary Digital Signal
Processor (DSP)
JVC’s innovative Digital Signal Processor automatically
adjusts camera parameters to ensure sharp and natural pictures
of 535 TV lines horizontal resolution with high-quality performance.
1/3-inch CCD with 440,000 Effective Pixels
JVC’s TK-C920E and TK-C921EG come with a 1/3-inch Interline
Transfer (IT) CCD for accurate colour reproduction and super
LoLux sensitivity of 0.7 lux F1.2.
Detail Corrections — Horizontal and Vertical (2H)
The TK-C920E and TK-C921EG provide dual-edged detail correction — horizontal
and vertical, dual-edged with 2H line memory.
Signal-to-Noise Ratio of 50dB (AGC Off)
The sharp and high resolution pictures of TK-C920E and TK-C921EG
also achieve a signal-to-noise ratio of 50dB.
Super LoLux and Automatic Gain Control (AGC)
As the ambient light level falls the AGC seamlessly increases
the camera’s sensitivity. With Super LoLux turned on
the AGC will further increase the camera’s sensitivity
to 0.7 lux 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 White Tracking function
over a range of 2,300°K to 10,000°K.
