Encoding Setup

Encoding Setup

Type: The stream settings can be set different between 24 hour recording and motion recording. Users can select Regular Type or MD type to set settings for each type of recording.

Compression: Compression saves on bandwidth and HDD space used. H.264H is set up on each channel by default this will save the most network bandwidth and storage. H.264 is a little less compression and is the standard compression rate. H.264B is a basic compression and will help with unit’s playback on slow networks.
Resolution: This setting will auto adjust based on the camera plugged into the channel it is recommended not to change this setting.
Frame Rate (FPS): This is the frames per second that a unit will display the higher the number the smoother the video will look, the lower the number the choppier the video will look. The default for each channel is normally 15 frames. On most Dahua recorder the first channel and only the first channel can be set to 30 fps.
Bit Rate type: always keep bit rate type at CBR for good networks (10mbps download and 10mbps upload minimum) and VBR for slower networks (Anything under 10mbps on down or upload)
Bit Rate (Kb/s): Bit rate is the amount of data that the recorder is streaming the camera at. This is how much data is packed into every data packet per second. The default rate is 4096 kbps or 4mbps. This is a good rate for units on a fast network and have a medium to large amount of HDD space. On devices running on slower networks or have small amounts of HDD space it is recommended to set the Bit rate (Kb/s) to 2048.
Audio/Video: Check on each check box to enable the audio for each channel / camera. The last check box is for sub stream video and will come checked on by default and should always remained checked on.

Users can set up the Regular and MD stream type separately from each other. This allows for setting video stream to a low quality when nothing is happening, but then set the MD stream to high settings for better image quality when an event is occurring. This will save on network bandwidth and on HDD space used.
