Glossary

ActiveX Control

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.

DDNS (Dynamic DNS)

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.

DHCP (Dynamic Host Configuration Protocol)

A protocol that enables PCs to automatically get infor- mation from a server needed for accessing a network.

DNS (Domain Name System)

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.

FTP (File Transfer Protocol)

A protocol that is commonly used for transferring files over the Internet.

NTP (Network Time Protocol)

A protocol developed to accurately maintain time among hosts on the Internet.

PS·Data

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.

QVGA

Resolution with 320 x 240 pixels.

POP 3

A protocol for receiving e-mail stored on a server on the Internet or an Intranet.

POP 3 Server

A server that supports POP3, currently the most widely used mail sending protocol.

RAID (RAID5)

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.)

HDD

Stands for Hard Disk Drive (a high capacity storage device). This product uses hard disk drives instead of video tapes for recording.

IP address (Internet Protocol Address)

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.

LAN (Local Area Network)

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.

MAC address (Media Access Control address)

Fixed physical address assigned to network devices. Devices send and receive data based on this.

H.264

One of the compression methods of moving images.

NAT (Network Address Translation)

A technology for sharing a single global address between two or more PCs.

RAID (RAID6)

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.)

RS485

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.

SD memory card (Secure Digital memory card)

A small, lightweight and removable storage device hav- ing a large capacity.

SMTP (Simple Mail Transfer Protocol)

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.

SMTP server

A server that supports SMTP, currently the most widely used mail transfer protocol.
