CONTENTS

Thank you for purchasing our product.
This device is a multifunctional, high performance CCD camera developed for high end security.
The characteristics of this camera are as follows.
(1) High Sensitivity

The use of the high sensitivity 1/2”CCD realized the minimum scene illumination of 0.2 lux
with a colour image.

(2) Day and Night modes (DAY & NIGHT)

Displays a high quality color picture during the day and a clear black and white picture at

night.
(3) Electronic sensitivity UP function (SENS UP)
(4) ECLIPSER function (ECLIPSER)
(5) On screen display function (OSD)
(6) High definition
(7) Small size

Area to use/store

This device is an indoor camera. Do not use it outside.
Do not expose the camera to extreme light sources (lighting and sunlight) regardless of use.
Avoid using and storing in the following locations.

z Extremely hot or cold locations (operating temperature -10°C to +50°C)
z High humidity or dusty locations
z In rainy locations or locations exposed to water
z Locations exposed to rigorous vibration
z Near TV and radio transmitting station with strong signals

Care

z Wipe dirt off the casing with a soft dry cloth. For heavy soil, wipe off using a dry cloth after

cleaning with a cloth with a small amount of mild detergent. Disconnect the power cord prior
to cleaning.
Do not use flammable liquids such as alcohol, benzene or thinner. This may damage the
surface finish.

z Do not touch the surface of the CCD. If it gets dusty, wipe off with lens cleaning paper.

Other

z White spots may appear on the screen due to normal characteristics of the imaging device.

However, this is not a defect.
White spots may also be noticeable when using the electronic sensing UP function (SENS
UP). However, this is not abnormal.

z Colors may differ somewhat from actual colors depending on the lighting but this is not a

defect.

z Highly light-intensive objects (such as lamps) may cause vertical stripes to appear on the

screen. This is a normal characteristic of the imaging device and is not a defect.
