•Video Buffer: By default, the Surveillance Client will not use the video buffer, which means that video from cameras will be rendered instantly when received. Although this is the option that offers viewing with the least possible latency, the video may not be smooth enough as rendering depends on several external factors such as the quality of transmission via the network, the camera, load on the recording server, among others. When using the video buffer, the system will receive the images and keep a few milliseconds in memory and then reproduce the images constantly, greatly increasing the fluidity of the video, however, this feature will add greater video display latency, which may not be operationally viable for PTZ cameras, so the system allows the activation of the buffer according to the camera type:

oUse video buffer for fixed cameras: Enables video buffering for fixed cameras. Enter the buffer size in milliseconds.

oUse video buffer for PTZ cameras: Enables video buffering for PTZ cameras. Enter the buffer size in milliseconds.

•Use multi-thread for decoding via software: The Surveillance Client allows the use of multi-thread for H.264 and H.265 video decoding. This option can be used to speed up video decoding on the client, especially for ultra megapixel images. Using this option will add at least 1 frame of delay to the video, that is, at 30 frames per second the additional delay will be at least 33ms while at 7 frames per second the additional delay will be at least 143ms.
