JVC VN-C205 manual Characteristics, Operating Precautions, Introduction

Introduction

Characteristics

The camera uses a high-resolution 380,000 pixel, high-Senstivity CCD to realize high picture quality with horizontal resolution of 540 TV lines.

Frame Rate

Supports a maximum frame rate of 30 fps when resolution is 640 x 480 in the JPEG compression format.

Supports Multicast

Support for multicast enables sending of an image data to multiple PCs on the network at one time without lowering the frame rate.

Built-in CF (Compact Flash) Slot Interface with alarms and enables storage of a recording file in the CF card. Please purchase the CF card separately.

Motion Detection Feature

Enables output of alarm upon detecting motion of images within a specified area.

Built-in Web Server

Enables browsing using the Internet Explorer.

When shooting a bright object (eg. lamps,

etc.), white vertical streaks may appear on

the object on the screen. This is a

phenomenon (smear phenomenon) normal

to CCDs (solid-state image pickup devices)

and is not a malfunction.

The dome cover is hemispherical in shape, and

therefore images tend to be distorted at the

edges of the hemisphere. The edges of the

hemisphere is masked for this camera. When

the camera is tilted and pointed in the horizontal

direction, therefore, edges of the hemisphere

may enter the angle of view, hence causing

the upper end of the screen to appear dark

and the image to go out of focus.

When shooting an object that is near a light

source (eg. lightings) or with a large

difference in brightness, ghosting may occur

on the screen. This phenomenon is due to

JVC will not be liable for any damage resulting from the camera dropping due to incomplete installation by not following the installation instructions. Take caution when performing installation.

Before starting an important recording, be sure to perform a test recording in order to confirm that a normal recording is possible.

We do not accept liability for the loss of a recording in the case of it becoming impossible to record due to a problem in the video camera, VCR or video tape.

We do not accept liability for any damage to the camera in cases when it is dropped because of incomplete installation due to not observing the installation instructions correctly. Please be careful when installing the camera.

To save energy, turn off the power supply of the system when not in use.

This camera is intended for indoor use. It cannot be used outdoors.

Do not install or use the camera in the following locations.

•Places exposed to rain or water

•Places containing vapor or oil soot, such as kitchens

•Places exceeding the operating ambient temperature range (0˚ to 40˚)

•Places where corrosive gases are generated

•Places nearby radiation or X-rays as well as sources of strong radio waves or magnetism

•Places subject to vibration

•Places with excessive dust

Insufficient ventilation may cause the camera to malfunction. Be careful not to block ventilation around the camera.

This camera radiates heat from its surfaces (top panel facing ceiling and side panel). Do not install at a location that may trap heat, such as near the walls.

Do not install at a location that may expose the camera directly to cool air, such as nearby the air outlet of air conditioners. This may cause moisture to condense within the dome cover.

Dew condensation may occur when there is a drastic change in the ambient temperature of the camera, hence causing a malfunction. When the camera is installed at such locations, turn on the power after allowing it to dry for a few hours.

Do not point the camera lens at a strong light source such as the sun. Doing so may cause the camera to malfunction.

This camera contains a built-in AGC circuit. As a result, gain increases at dark places and screen may appear grainy. This is not a malfunction.

When an equipment that generates a strong magnetic field, such as transceivers, is used near this camera with the AGC turned on, beat noises may appear in the image. When using a transceiver, therefore, place it at least 3 m away from this camera.

If this camera or cable connected this unit is used near a location where strong electrical or magnetic waves are generated (eg. radios, TVs, transformers, monitors, etc.), noise interference may occur in the image or its color may be affected.

When this camera is used in the White Balance (ATW) mode, the colors captured may differ slightly from the actual colors due to the operational principles of the auto-tracking white balance circuit. This is not a malfunction.

been supplied.

Certain Hubs/switches that are equipped with

the SNMP feature may come with a broadcast

or multicast control function. Proper viewing

of multicast images created by this camera

may not be possible if this function is enabled.

Do not touch the dome cover with your hand.

This may dirty the cover and cause the image

quality to deteriorate.

To clean the camera.

• Do so upon turning off the power.

• Use a lens cloth (or paper) to remove dirt

from the dome cover. The camera may

acquire dirt over a short period of time,

depending on the environment of use.

When there is excessive dirt, wipe using a

lens cloth (or paper) upon wetting it in a

neutral detergent diluted with water.

If the D/N switch is turned on, the mode

changes automatically to black and white in

dark places. As the sensitivity increases, the

image may look grainy and white spots may

appear. When changing modes, bright

portions of image may be emphasized but

this is not a failure of the camera.

The unit is to be powered by a DC 12 V or an

AC 24 V power supply.

The AC 24 V power supply should conform to

the following : Class 2 only (For USA), Isolated

power supply only (For Europe).

The rating label is displayed on the underside

of the body.

Image sending may be affected when this is done on a network where multicast transmission devices are connected, or on networks for which there is transmission of voluminous broadcast data. When this occurs, ensure to employ a system design that separates the camera from other multicast or broadcast devices by making use of a switching valve or VLAN with a multicast control function.

When using the local recording feature with a CF card, turning off the power during local recording may damage the file. To prevent damage of the file, make use of a UPS (uninterruptible power supply).

Warning

Install at places that are strong enough to support the camera weight.

Install this camera at places that are strong enough to support its weight upon taking into consideration the vibration force during high-speed rotation as well as its mass (approx. 1.0 kg). For ceiling materials that are weak, such as overlay plywood and plaster boards, reinforce by applying reinforcements (veneer plywood). If reinforcement is inadequate, image on the monitor screen may be blurred due to vibrations. In the worst scenario, it may even fall and cause serious injuries if there is someone underneath.
