Chapter 1 Introduction
1.1 Description
Developed on the basis of the latest encoding technology, the BEU-4 allows the analog signal to be digitized and
then stored in hard disk or transmitted via network.
Adopting the latest embedded processor, the BEU-4 provides more powerful capabilities in audio/video encoding;
standard 1U chassis design maintains easy installation; multiple network transmission protocols supported; and
code downloaded in FLASH ensures high stability and reliability of system performance.
1.2 Features
Encoding
Support H.264 encoding standard at PS and RTP customized encapsulation formats, of which RTP stream is used
for transmission via network and PS stream for recording;
Support encoding at 4CIF, 2CIF, CIF and QCIF resolutions;
Dual stream encoding;
Either compound streams encoding or video stream encoding selectable; audio and video synchronization during
compound streams encoding.
Recording
Multiple Recording Periods Configurable
Up to 8 recording periods can be configured for each day, with different recording type selectable for each
recording period.
Cycle Recording
Either cycle recording or non-cycle recording mode is configurable. In cycle recording mode, the earliest recoding
will be overwritten when the HDD is full; and in non-cycle recording mode, the system will stop recording and
give alert when HDD is full.
Scheduled & Event Recording
Each channel can be set with the scheduled recording and event recording separately, with separate resolution, bit
rate, frame rate and stream type configurable.
