MPEG-4
The MPEG (Moving Picture Experts Group) 4 standard was
designed to reproduce a wide range of moving pictures
from those on a low speed communication line to those
with high-definition TV picture quality. It is especially
effective for application on low speed networks. While
conventional MPEG1/2 encodes only portions of the picture
that have changed from the key frames, MPEG-4 employs a
new technique to disassemble a frame into objects. Simply
put, it disassembles a picture into elements such as
backgrounds, persons, buildings, etc. and records
differentials or each object. The method is similar to that of
M-JPEG recording format and things that can be handled as
MPEG-4 objects are not limited to of physical nature, but
include audio as well.
Low Rate but High Quality
Since MPEG-4 offers quality pictures at a low bit-rate, it is
possible to record pictures for a considerably longer time
compared to JPEG.
Network
DSR-2016 / DSR-2004 offers network connectivity with
LAN and WAN. MPEG is an international standard for highly
efficient digital encoding (compression) of video and audio
signal and is indispensable for video signal compression and
transmission over a network. Compared to conventional
systems, DSR-2016 / DSR-2004 offers improved
surveillance video transmission — clear pictures at low bit-
rate — by the adoption of MPEG-4.

Simultaneous Recording/Playback at 200 IPS (DSR-2016)
The DSR-2016 offers the capability to smoothly record and
playback movement at a maximum rate of 200IPS. It also
features two HDD bays, enabling expansion of storage
capacity up to 1TB.
Simultaneous Recording and Playback
The simultaneous recording and playback function makes it
possible for the user to review recorded images without
interrupting the recording in progress (in the CIF mode,
360x240 pixels).
Triplex Function
The Triplex function of DSR-2016 / DSR-2004 makes it
possible to perform three functions simultaneously, i.e.
recording, playback, and network monitoring.

Built-in Motion Sensor
DSR-2016 / DSR-2004 comes with a built-in motion sensor.
Different settings can be made for each channel image
independently. The sensor can detect moving objects within
the screen by picking up changes in brightness. The user can
use this feature to trigger an alarm recording.
Audio Recording Available
The unit comes with 4ch input and 1ch output terminals to
enable audio recording of each channel.
Two-way Audio over a Network
During a remote surveillance, it is possible not only to receive
audio, but also to send a warning message to the point of
surveillance.
