Default gateway

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.

Cable compensation

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).

Combination camera (PTZ camera)

Indicates a camera with the panning/tilting and zooming function. Also known as PTZ camera.

Subnet

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/Subnet prefix length

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.

Sequence

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.

Schedule recording

Function that automatically starts video and audio recording on a preset time schedule.

Secondary (DNS) server

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.

Multiscreen display

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.

Electronic zoom

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.

Coaxial communication

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.

Disk configuration (Disk config.)

It is necessary to configure the HDD settings after replacing, removing, or adding a HDD. "Disk config." is the menu for configuring the HDD.

Half duplex

Communications method that switches between send- ing and receiving using a single communications line.

Bit rate

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.

Firewall

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.

Private (IP) address

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.

Full duplex

Communications method that allows simultaneous sending and receiving by transmitting in both directions using an independent sending line and receiving line.

Time zone

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

Primary (DNS) server

DNS servers usually have more than 2 systems and the primary server is the main system.

Plug-in software

Small programs used to add functions to application software.

Broadband router

Router used to access the Internet via high-speed ADSL or fiber optic lines.
