A software module developed by Microsoft. It is used to 

add functions, downloaded from a web server via the 

Internet or intranet, to Internet Explorer. The recorder 

uses it to display video. 

A technology for dynamically translating DNS server 

information to enable the transfer of only differences in 

information between DNS servers (refer to "DNS"). This 

reduces the data transfer amount necessary for updat-

ing information on the DNS server and reduces the load 

on the network. 

A protocol that enables PCs to automatically get infor-

mation from a server needed for accessing a network.

The long lists of numbers or IP addresses that are used 

in network environments are difficult to remember, which 

makes them impractical. This is why PCs are given an 

easy-to-follow name (domain name) which is converted 

to an IP address before they are communicated with. 

The DNS provides translation between domain names 

and IP addresses. 

A protocol that is commonly used for transferring files 

over the Internet.

Stands for Hard Disk Drive (a high capacity storage 

device). This product uses hard disk drives instead of 

video tapes for recording. 

The identification number assigned to PCs connected 

via IP networks such as the Internet or an Intranet, or to 

individual communications devices. Do not assign the 

same address to multiple devices, especially on the 

Internet.

A communications network for connecting PCs, printers 

and other network devices in a relatively small area such 

as in a building or floor of a building or campus in which 

data is transferred. 

Fixed physical address assigned to network devices. 

Devices send and receive data based on this. 

One of the compression methods of moving images. 

A technology for sharing a single global address 

between two or more PCs. 

A protocol developed to accurately maintain time among 

hosts on the Internet. 

Stands for Panasonic Security Data. When PS·Data 

compatible devices are connected using a RS485 cable, 

it is possible to operate the recorder from them or to 

operate them from the recorder. 

Resolution with 320 x 240 pixels. 

A protocol for receiving e-mail stored on a server on the 

Internet or an Intranet.

A server that supports POP3, currently the most widely 

used mail sending protocol.

An abbreviation for Redundant Arrays of Inexpensive 

Disks 5 that provides a highly reliable disk array by dis-

tributing access over multiple HDDs, increasing both 

speed and capacity. Even if one HDD has errors, data 

can be recovered based on error correction data record-

ed on other HDDs. (RAID 5 is used when 3 or more 

HDDs are connected. However, when 2 or more HDDs 

simultaneously have errors, data cannot be recovered.)

An abbreviation for Redundant Arrays of Inexpensive 

Disks 6 that provides a highly reliable disk array by dis-

tributing access over multiple HDDs, increasing both 

speed and capacity. Even if two HDDs have errors, data 

can be recovered based on error correction data record-

ed on other HDDs. (RAID 6 is used when 4 or more 

HDDs are connected. However, when 3 or more HDDs 

simultaneously have errors, data cannot be recovered.)

When this product is connected to the camera using the 

video cable and the RS485 cable, the electrical charac-

teristics of RS485 can make this product to control the 

camera. 

A small, lightweight and removable storage device hav-

ing a large capacity. 

A protocol for sending e-mail on the Internet or an 

Intranet. Used when transferring mail between servers or 

when clients send mail to the server.

A server that supports SMTP, currently the most widely 

used mail transfer protocol.
