External recording mode

Function for changing the programmed time schedule through an external switch connected to the unit.

Event

An event is a phenomenon which triggers a specific operation (event operation) in the unit. Events are divided into terminal alarm, command alarm, and site alarm.

Event Action

Event action refers to a specific operation performed when an event occurs. Event operations are divided into ALM (Alarm Mode), ADM (Activity Detection Mode), and are selectable. In ALM, the occurrence of an event is announced by screen display, LED, or buzzer (Alarm Operation). In ADM, the occurrence of an event is not announced, but the unit starts event recording, performs the preset operations, and enters the event into the event log. In OFF mode, the unit only enters the event into the event log.

Sequence

Sequence refers to automatically changing the displayed camera picture in a preset sequence. Sequence display is possible while the unit displays live pictures.

Electronic zoom

Function for enlarging live and playback pictures. While the camera uses the camera zoom function to enlarge pic- tures, the electronic zoom function enlarges the picture electronically in the unit and displays it.

Camera control

Camera control refers to controlling the functions of the combination cameras connected to the unit. These functions include Pan/Tilt, Zoom, Focus, Brightness, Preset Operations (moving the camera to a preset horizontal/vertical position), and Auto (for example, automatic panning).

A-B repeat playback

Function for playing back repeatedly between a set start point (A) and an end point (B) in playback mode.

HDD safety mode

Function for turning off the power supply to the HDD to prevent damage of the HDD due to vibration and shock if the unit is mounted in or dismounted from the rack with the power turned on.

Disk config

When an HDD is replaced, removed, or added, the HDDs need to be newly configured. Disk config refers to the menu for performing these HDD settings.

RAID (RAID5)

This stands for Redundant Arrays of Inexpensive Disks. It refers to a technology to implement a high-speed large- capacity and high-reliability disk unit by distributing access to multiple HDDs. If trouble occurs in one of the HDDs, the data on the faulty HDD can be recovered based on the error correction data recorded on the other HDDs.

(RAID5 is used when 3 or more HDDs are connected. If trouble occurs simultaneously in 2 or more HDDs, the data of the faulty HDD cannot be recovered.)

System Administrator

This refers to a person who has the responsibility and authority to operate the unit and perform settings.
