What is the DVR?
========================================== = = = = = = = = = = = = = = = = = =
This system digitalizes and stores the analog video and voices on a storage device, and allows users
to search by any criteria they specify and to transmit the image through a network. This is commonly
known as the DVR(Digital Video Recorder).
1. System Features
========================================== = = = = = = = = = = = = = = = = = =
1) Stabilized System
This system has been stabilized and verified by six years of research and development.
2) Efficient File System
The system stores data on baskets which are the disk space partitioned into certain areas. This file
system efficiently aligns data and maximizes the speed of data processing. In addition, the stored
data is effectively protected.
3) Outstanding Image Quality and Search Methods
The system provides various search conditions and an excellent image quality for searching an event
or constantly saved data.
4) Convenient User Interface
The system allows users to operate it with simple mouse operation in a GUI environment for
convenience.
5) Various Network Functions
The system provides the remote monitoring, recording, searching, sending, and controlling functions
as well as the two-way voice communication through a network in real time. The transmission can
also be enabled using a telephone modem and diverse networks.
2. Major Functions
========================================== = = = = = = = = = = = = = = = = = =
Maximum 16 real time images can be monitored.
30 ~ 480 frames can be recorded, and the system is equipped with an efficient MPEG4
coder/decoder.
Each camera can be operated with different compressing methods and recording speeds.
The system uses the same method used to save file systems and provides a stable recovery
function for file systems.
The system provides the remote monitoring (LAN, PSTN, ISDN), Single & Multi RDVR, two-
way voice communication functions.
The saved data can be backed up using searching and various backup devices (DAT, DVD, ADR,
DLT, CD-RW, On-Stream).
Various searching methods: Event search, motion search, panorama search, search by minute, jog
shuttle search, and search by camera combination
System monitoring function (Watch Dog)
Remote notification function ( PDA, email, text transmission )
Audio recording function
The system distinguishes the function for each user and provides him/her appropriate account and
password ( Multi-Level Password )
Various type of alarms (beep sound, moving line, enlarged screen, and email)
