High effective RTOS and embedded processor are adopted in this series DVR, as well as all functions needed for the monitoring system are integrated. Code is solidified in the flash
chip to keep the system in high stability and reliability. 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 products and different hardware and software versions.
2.2 Main Functions
u 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 adopts G.711A, and every video/audio signal is compressed separately in real time, then generate composite compressed code stream. The video
and audio stream are synchronous when playback, or setting disable audio with the sampling rate of 8K sample/sec., 16 bit/sample.
5. Supporting dual stream compression: main code stream used for local storing, sub code stream used for image transmission in low-bandwidth network.
6. 6 levels of record quality is available to select. Users can choose according to requirements so that the recording time is long enough.
u Recording function
1. Support 4 record modes: manual, schedule, motion and alarm recording.
2. Support 5 screenshot modes: manual screenshot; manual, schedule, motion and alarm snapshot.
3. Video motion detection function: multi detection areas can be set up to 5 sensitive levels.
4. Support screen shield. Each channel can max setting 4 mask areas, support preview mask, record mask and all mask.
5. Each channel support 4 interested area setting.
6. Support sensor alarm. One sensor can be linked to one or more cameras. Support alarm recall to PTZ preset point.
7. Monitoring center can record the real time compression code stream, and support synchronizing record video and audio into client PC.
8. Video and audio parameters of each camera can be set up separately.
