Chapter

Before Using the VB-C300

This chapter describes the features of the VB-C300, the hardware and software requirements, and the name and functions of the system components.

Features of the VB-C300

The VB-C300 is a network camera integrating a camera and server functions into a compact form

factor.

AF Zoom lens with horizontal viewing angle of 70° and pan/tilt functions

The VB-C300 has a zoom lens with horizontal viewing angle of 70° and optical 2.4X (and digital 4X)

zoom lens which can capture a wide range at a time. In addition to a bird’s eye view of the entire area, the VB-C300 can capture a wide-angle image even if it is close to the object. The VB-C300 has the AF

capability as well as pan and tilt functions to move the camera horizontally and vertically, allowing

easy adjustment of the viewing angle when the layout of the target area is changed. These functions

are also useful when monitoring the situation by remote-controlling the camera.

High-quality video of moving objects

The VB-C300 uses the progressive-scan CCD to allow capturing noise-less high quality images

of moving objects.

Color capturing under 1 lux and auto Day & Night

The VB-C300 can capture color images under as dark as 1 lux (NTSC: 1/30 sec. PAL: 1/25 sec.)

in the Day mode and monochrome images under as dark as 0.25 lux (NTSC: 1/30 sec. PAL: 1/25

sec.) in the Night mode (by disabling the infrared cut filter).The VB-C300 also has the Day & Night switching function* (→ dOperation Guide P.1-10) to automatically switch between color

capturing under bright conditions during daytime and monochrome capturing under dark conditions during nighttime, making the camera suitable for monitoring at locations where environmental

brightness changes during a day.

* A through test is required in advance to use the Day & Night switching function.

Video distribution server function

Motion-JPEG type is used to compress video images to enable distribution of high-quality videos

at a high frame rate (NTSC: up to 30 fps, PAL: up to 25 fps*) with VGA (640 x 480) size. Up to 15 clients can view video at the same time from a single VB-C300.

* The frame rate may be decreased depending on the Viewer PC’s capability or network traffic.

Camera position presets

By saving frequently-used camera settings such as camera head aim and zoom position as presets,

you can control the camera from the NC Viewer by simply selecting a desired preset. Up to 20 presets can be set (→ dOperation Guide P.2-10).

Panorama Image Creation function and various settings

The full view of the area that camera covers can be registered as a panorama image. You can

define presets visually and easily by using a registered panorama image.

Transmission and reception of audio (full duplex)

You can send and receive audio via the NC Viewer (full duplex) by connecting a microphone and

speaker with amp to the camera*.

* The microphone and speaker are sold separately.

1-2

Features of the VB-C300

Upright Position and Ceiling Mount

The VB-C300 can be mounted at the upright position or on the ceiling by simply changing settings (→ dOperation Guide P.1-9).

* The camera cannot be installed in locations subject to direct sunlight, high temperatures, high

humidity, or other adverse conditions (→ P.x).

Compact and Stylish Design

The camera’s stylish design fits various environments as a part of construction or interior. Also the supplied ceiling mount cover will hide the ceiling bracket and cables (→ P.vi) when mounting

the camera on the ceiling.

PoE Function

The camera is capable of the PoE function to transfer video/audio data and supply power via a

LAN cable connected to a PoE* HUB (→ P.xiii). You do not have to prepare power supply if you

connect the camera to a PoE HUB.

*Power over Ethernet. Compliant with the IEEE 802.3af standard by the Institute of Electrical and Electronic Engineers.

Up to 100 m of the LAN cable can be connected between the camera and the PoE HUB (→ P.xiii).

Shade Correction Function (NC Viewer)

If the background of an image is bright, making the subject difficult to see, you can adjust the

contrast of the darker areas to make it easier to see. Unlike backlight compensation, the shade

correction feature allows image processing without adversely affecting the existing lighter regions (→ dOperation Guide P.3-29).

Optional Indoor Dome Housing for Various Mounting Options

You can use the optional indoor dome housing (→ P.1-9). Two types of dome housing are provided.

The Smoke type hides the presence of the camera and the Clear type appeals the presence of

the camera while protecting it from dusts. You can install the camera as a dome camera and

allow various mounting options.
