CONCEPT

New TK-C1480E series

When JVC introduced its TK-1280E series and TK-C1380E series to the 1/2" camera market,

they are widely accepted and recognized as standard-setting cameras.

The new TK-C1480E series, which is to maintain market leadership, adopts newly developed

DSP and CCDs, which feature much higher sensitivity, as well as more functions than its

predecessor, the TK-C1380E series. Added functions include: backlighting and remote

surveillance with RS-422A/RS-485 communications.

Features

Using the 1/2-inch EXVIEW CCD permits sensitivities of 0.8 lux (F 1.2, 50%) and 0.4 lux (F

1.2, 25%). When combined with the slow shutter function, these are increased to 0.025 lux (F

1.2, 50%) and 0.0125 lux (F 1.2, 25%), respectively.

Until now it has been difficult to clearly distinguish between bright and dark subjects in the

same view. With the introduction of JVC’s newly developed DSP this shortcoming no longer

exists, making 24-hour surveillance possible.

For remote camera parameter setting in repeat surveillance communication, RS-422A/

RS-485 standards are provided. An easy-to-use parameter setup menu and high-quality

shooting with no backlight, both of which are popular functions of the TK-C1380E, are also

adopted by the new series.

Wave Length (nm)

Because there is a difference in the spectral response of the CCD between TK-C1380E and TK-C1480E, the same color reproduction is difficult to obtain. (Of course, we have tried to adjust the color matrix of the TK-C1480E so that it is as close as possible to that of TK-C1380E.)

DETAILED FEATURES

ExDr

ExDr mode: This is the shutter mode for a subject for which strong light and normal (or low) light conditions coexist.

The ExDr mode is divided into two further modes: Manual ExDr mode and Auto ExDr mode.

1 Manual ExDr mode:

Selectable high speed shutter  1/500 to 1/20,000

Other Competitors style: Fixed

Variable contrast level

 +5 to -5  Minus (-) direction: The iris is set at strong light.  Plus (+) direction: The iris is set at low light.

Other Competitors style: Auto only

2 Auto ExDr mode:

The iris at the strong light portion and at the low light portion can be automatically detected and the results are combined to determine the required shutter speed.

Variable contrast level

 +5 to -5  Minus (-) direction: Adjusted for strong light  Plus (+) direction: Adjusted for low light

High-speed side shutter operation for ExDr-AUTO

SHUTTER LENS

(Auto Iris Operation)

Sees the highest peak on the divided-by-48 portion.

Adjusts (and sets) the shutter so that the peak value may become a certain level.

Lowers the high-speed side shutter speed (down to 1/100 second)

If still too dark for a speed of 1/100 second, then WD is set to OFF (WD-AUTO). And at a speed of 1/50 second AGC is turned ON.

Simultaneous operation

When the lens is fully open because the area is too dark as a whole.

(Note) Slow shutter mode is not available for WD-ON and manual operation.

Auto Exdr, Auto and Normal modes are available for Sense Up operation. Manual Exdr and Manual modes are not available for Sense Up operation.
