11. Streaming: sets the video stream protocol (HTTP is recommended)

The product provides three different video streaming protocols: UDP, TCP, and

HTTP. HTTP is the most recommended because it allows the video stream to go

through the firewall. (Refer to Setting/Basic Setting/Network/Streaming for more

information).

UDP: It provides the fastest but unreliable transmission service. Video steams are

transmitted thought UDP Port (50000~60000 by default) to ensure the

fastest image transmission. However, video fragment or mosaics may occur

due to poor transmission quality.

TCP: It provides reliable data transmission. Video steams are transmitted through

RTSP Port (554 by default) to avoid video fragment or mosaics due to poor

transmission quality.

HTTP: Video streams are transmitted through HTTP Port (80 by default) to ensure

going through firewalls.
