Panasonic WJ-HD616K 用户手册

131

Network device used as a gateway for networks, such 

as a local network, to access PCs on an external net-

work. Data is sent using the default gateway if a gate-

way is not specified in the destination IP address.

Generally, video signals will be attenuated when using a 

long cable to connect between the recorder and the 

camera. The cable compensation function compensates 

this attenuation. In this product, the cable compensation 

function compensates video signals from the cameras 

connected to the video input connectors 1 - 8 when 

using the WJ-HD616K (the video input connectors 1 - 16 

when using the WJ-HD716K). 

Indicates a camera with the panning/tilting and zooming 

function. Also known as PTZ camera.

A small network used as a unit of administration when a 

larger network is divided into smaller networks. Large 

networks in corporations, for example, the network can 

be broken down into smaller networks called "subnets" 

to make the network more manageable and lines used 

more efficiently. In this case, these smaller networks are 

called subnets.

Subnet mask consists of 32-bit numeric values. 

According to the values, devices can determine which 

part of the address is the network address and which 

part is the host address.

The function that can sequentially display images from 

cameras in order set in advance. In this product, the 

sequence can be performed during displaying live imag-

es. 

Function that automatically starts video and audio 

recording on a preset time schedule.

DNS servers usually have more than 2 systems and the 

secondary server is the sub system. 

If there is trouble with the primary server, the secondary 

server takes over.

Communications method that allows simultaneous 

sending and receiving by transmitting in both directions 

using an independent sending line and receiving line.

A time zone is a region or a country that has uniform 

standard time.

This product can display images from multiple camera 

channels simultaneously while displaying live images or 

playback images. Displaying of images from 4 cameras 

or from 16 cameras simultaneously is called as 

"4-screen display" or "16-screen display" respectively. 

The function that enlarges live images and playback 

images during playback. The electronic zoom enlarges 

the images by the recorder and is separate from the 

zoom function included as part of the camera operations 

for enlarged images.

This method is used to control the camera using the 

camera control signal through the cable connecting 

between the recorder and the camera. In this product, 

the cameras connected to the video input connectors 1 

- 8 (1 - 16 for WJ-HD716K) can be connected using the 

coaxial communication. 

It is necessary to configure the HDD settings after 

replacing, removing, or adding a HDD. "Disk config." is 

the menu for configuring the HDD. 

Communications method that switches between send-

ing and receiving using a single communications line.

Indicates how many bits of data can be processed or 

transmitted in a unit of time. Generally, the units are in 

bps, or bits per second. Used to indicate the compres-

sion rate of video and audio data, and how much data a 

communications line can send and receive in 1 second. 

A type of security used when accessing outside net-

works like the Internet. A PC is used to prevent comput-

ers outside a local network from accessing the network.

IP address assigned when connecting primarily to LAN. 

Private IP addresses can be assigned freely on a net-

work and do not require a formal application. However, 

because private IP addresses cannot be used to access 

the Internet, a router or other device it is necessary to 

assign a global IP address.

DNS servers usually have more than 2 systems and the 

primary server is the main system. 

Small programs used to add functions to application 

software.

Router used to access the Internet via high-speed ADSL 

or fiber optic lines.
