2.2 Main Functions
High effective RTOS and embedded processor are adopted in this series DVR, as well as all func tions needed for the monitoring system are
integrated. Code is solidified in the flash chip to keep the system in high stability and reliabilit y. System can also work in a long time surveillance
environment and even in stringent circumstance.
Note: The following features might differ from the below description since we have series prod ucts and different hardware and software versions.
 Compression features
1. Support PAL/NTSC video format signal.
2. Video compression algorithm is H.264.
3. Video and audio signals are compressed into H.264 code stream. Audio and video stream are synchronous when playback, and audio recording can be
canceled if only video is in need.
4. Audio compression algorithm adopt G.711A, the video and audio signals of each channel is compress ed in real time and separately, then become a
composite compressed code stream .The video and audio stream are synchronous when playback, you can also setting disable audio. Audio sampling rate:
8K sample/sec., 16 bit/sample.
5. Support dual stream encode.Main code stream used for local storing ,sub code stream used for tran smission to internet in narrow bandwidth condition.
6. 6-level record quality is provided for you to select. Users can choose any preferred one.
