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.

Spectral Response

TK-C1380E (Conventional CCD) TK-C1480E (EXVIEW CCD)

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.)

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.

1Manual 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

2Auto 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

Slow Shutter

Available (selectable) modes are: Off, x2, x4, x8, x16, x24 and x32. The same picture is stored in multiple fields

to obtain increased sensitivity.

In this case a decrease of resolution of 50% results when only even fields are used (odd fields are not used).

P.S. Priority Mode

The slow shutter speed can be used when AGC is ON.

1Motion

AGC is turned ON first, followed by slow shutter-ON.

(Motion picture priority mode)

2Picture

If AGC is turned ON first, noise tends to be introduced.

To prevent noise slow shutter is turned ON prior to turning AGC ON. If, however, the prime requirement is

sensitivity, AGC is turned ON first (with no consideration given to increased noise).
