1. Handling precautions
• Do not install the camera in a water-splashed or highly humid place.
• Do not use the camera where the ambient temperature drops below -10°C or rises
above +50°C. The images and component parts may be adversely affected or the
camera may get in trouble.
• Never open the case of the camera because there are precision parts inside.
Otherwise a trouble or accident may result.
• Do not put anything metallic and other foreign substances through the vent. A trouble,
fire or electric shock may result.
• Be sure to turn off the power before installing or making connections.
• Do not install the camera in places exposed to vibrations and shocks.
• Be very careful not to drop or shock the camera while carrying it in.
• Do not touch the imaging device
• Do not orient the camera to the sun.
• Some types of lenses may cause hunting, light amount drop or other problems. In
such case, readjust the lenses.
* Because of the digital image device characteristics, images may look rugged at high
temperatures. This does not mean the camera is in trouble.
2. General
This color camera is provided with a 1/3-inch approximate wide dynamic range (WDR)
digital image device. The CCTV camera features wide dynamic range, high sensitivity
and high resolution, and is equipped with the back-light compensation, automatic iris
control, line lock and other functions. The unit is best suit d for general surveillance.

E-2
3. Features
(1)Wide dynamic range (WDR)
The WDR function provides for backlight compensation in a wide dynamic range.
Being shot even in wide-illumination-fluctuating spots, bright-and-dark subjects can
be captured clearly and in a natural look.
(2)Automatic white balance
Thanks to the automatic follow-up white balance control (ATW), the white balance
adjusts itself no matter how greatly the subject's color temperature fluctuates.
(3)High-quality picture and high resolution
The camera is designed for low smear level and low noise. The DSP (Digital Signal
Processor) effectively enhances details, which achieves crisp and sharp images with
high signal-to-noise ratio. The high resolution is backed up by a horizontal resolution
of 480 TV lines and a vertical resolution of 400 TV lines.
(4)High sensitivity
Various modes of automatic gain control (AGC) are available to finely adjust the camera
settings depending on the subject's illumination conditions. With the AGC and slow
shutter in combination, high sensitivities of up to 0.015 lux/F1.4 are achieved.
(5)Camera setup function
The control buttons on the back of the camera enable to change and save the camera's
settings.
(6)Two-way automatic iris control
This function is available to switch between video type iris lens and DC type iris lens.
In other words, almost all types of CCTV automatic iris lenses can be employed.
(7)The flange focal distance adjusting mechanism makes it easy to readjust the focus
tracking when a zoom lens is used.

1. Precauciones de manejo
• No instale la cámara en un lugar donde se salpique agua o donde haya mucha
humedad.
• No utilice la cámara donde la temperatura ambiental sea inferior a -10°C o superior a
+50°C. Las imágenes y las piezas componentes podrían ser afectadas o la cámara
podría funcionar mal.
• No abra nunca la caja de la cámara porque en su interior hay piezas de alta precisión.
De lo contrario podría producirse un problema o un accidente.
• No meta ningún objeto metálico ni otras sustancias extrañas a través de las aberturas
de ventilación. Podría producirse un problema, un incendio o una descarga eléctrica.
• Asegúrese de desconectar la alimentación antes de instalar la cámara o hacer sus
conexiones.
• No instale la cámara en lugares expuestos a vibraciones o golpes.
• Tenga cuidado para no dejar caer ni golpear la cámara mientras la transporta.
• No toque el dispositivo de imagen.
• No oriente la cámara hacia el sol.
• Algunos tipos de objetivos pueden causar fluctuaciones, reducción de iluminación u
otros problemas. El tal caso, vuelva a ajustar el objetivo.
* Debido a las características del dispositivo de imagen digital, las imágenes pueden
aparecer alteradas a alta temperatura. Esto no significa que la cámara esté estropeada.

3. Características
(1)Gama dinámica amplia (WDR)
La función WDR proporciona compensación de luz de fondo en una amplia gama
dinámica. Filmados incluso en lugares donde la iluminación fluctúa considerablemente,
los motivos brillantes y oscuros se pueden captar claramente con un aspecto natural.
(2)Balance automático del blanco
Gracias al control del balance del blanco de seguimiento automático (ATW), el balance
del blanco se ajusta automáticamente sin importar lo grande que sean las fluctuaciones
en la temperatura del color del motivo.
(3)Imagen de alta calidad y alta resolución
La cámara ha sido diseñada para que tenga niveles de poca borrosidad y poco ruido.
El DSP (procesador de señal digital) mejora eficazmente los detalles, lo que produce
unas imágenes claras y nítidas con una relación señal a ruido alta. La alta resolución
cuenta con el apoyo de una resolución horizontal de 480 líneas de TV y una resolución
vertical de 400 líneas de TV.
(4)Alta sensibilidad
Se encuentran disponibles varios modos de control automático de ganancia (AGC)
para ajustar con exactitud la configuración de la cámara dependiendo de las
condiciones de la iluminación del motivo. Con la combinación del AGC y el obturador
de baja velocidad, se alcanzan sensibilidades de hasta 0,03 luxes/F1,4.
(5)Función de configuración de la cámara
Los botones de control en la parte posterior de la cámara permiten cambiar y guardar
la configuración de la cámara.
(6)Control automático del iris de dos formas
Esta función se encuentra disponible para poder cambiar entre el objetivo con iris tipo
vídeo y el objetivo con iris tipo DC. Es decir, se pueden emplear la mayoría de los
tipos de objetivos con iris automático CCTV.
(7)El mecanismo de ajuste de distancia focal de brida facilita volver a ajustar el
seguimiento de enfoque cuando se utiliza un objetivo zoom.
