Chapter 1 Introduction
Network camera is a kind of embedded digital surveillance product that combines
both the features of traditional analog camera and net DVS (Digital Video Server). Due
to the embedded Linux operation system and the latest Davinci hardware platform of
TI, the system operates with high scheduling efficiency. Furthermore, the firmware is
burned in the flash, which makes the product small, reliable and highly stable.
1.1 Functions and Features
Functions
Video Encoding Techniques:Introduced H.264 video encoding standard which
provides high compression ratio and flexible processing.
Network Function:Support the complete TCP/IP protocols, video/alarm/audio data
and IE browsing.
Heartbeat Function: The server can acquire real time operating performance of the
network camera through the heartbeat function.
PTZ Control:Support various kinds of decoder protocols and PTZ types.
Alarm:The product includes 1 channel of alarm signal input and 1 channel of alarm
on/off output, and supports motion detection, video missing, mask alarm and
external alarm input.
Voice Talking :Support bidirectional voice talking and unidirectional voice
broadcasting.
User Management: Support multilevel right management. The administrator can
create up to 15 separate users with different right levels, which highly improves the
system security.
Compression Functions
The camera supports 1 channel video signal and 25fps real time H.264 stand alone
hardware compression, which supports both variable bit rate and variable frame rate;
besides, you can self-define both the video quality and its compressed bit rate.
Support resolutions from 4CIF(PAL:704*576,NTSC:704*480), DCIF (PAL:
528*384,NTSC:528*320), 2CIF(PAL:704*288,NTSC:704*240), CIF(PAL:
352*288,NTSC:352*240)to QCIF(PAL:176*144,NTSC:176*120).
Support OSD and date & time settings.
Support watermark techniques.
Remote Control
The product offers a 10M/100M self-adaptive Ethernet interface.
Support PPPoE and DHCP protocols.
You can set the parameters, browse real time videos or check the camera
performance through software or IE, and get external alarming or save the
compressed bit rate through network.
Support remote upgrades and maintenance.
RS-485 supports unidirectional transparent channel function so that clients on
remote PC can control the serial devices.
