High through put is achieved by separating the camera port and the
client PC port. In addition to acquiring extremely stable images, you
can connect a maximum of 64 cameras and 16 client PCs,
depending on your network.

Recording

Camera images from network cameras are recorded on the
recorder. One Network Disk Recorder can record images from a
maximum of 64 cameras. JPEG, M-JPEG, and MPEG-4 images are
supported.

Playback

Images recorded on the HDD of the recorder are sent to and
displayed on a PC. One Network Disk Recorder can send images to
a maximum of 16 PCs.

Accessing Live Images

Images from network cameras can be sent live to PCs via the
recorder. Images from a maximum of 64 network cameras can be
sent simultaneously to a maximum of 16 PCs.
Schedules can be made so each day can be divided into six time
zones, each of which can be programmed separately. Up to 8
different programs can be created. It is possible to set the recording
rate, event recording time, and other items for each program.

About Events

Events are things that trigger special operations by the recorder.
The event function includes terminal alarms, site alarms, and
command alarms.
For example, if a camera sends a site alarm, the recorder receives
the alarm and an event occurs.

About event operations

Event operations are the operations done when an event occurs.
Event operations include, depending on the settings, recording
images, recording logs, sending external notification (mail
notification, LED, buzzers, FTP transmission and others). Here,
operations that send external notifications are called alarms.
The recorder starts an event according to the settings when the
following events occur.
