What is the difference between using TCP and UDP in video surveillance?
Question
What is the difference between using TCP and UDP?
Answer
Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) are widely used network protocols. Video is sent using either RTP over UDP or RTP over TCP as part of the underlying transmission protocol.
• Both TCP and UDP are part of the IP4 protocol stack.
• Both break down data into frames and packets for transmission via ethernet.
• Most IP cameras support both TCP and UDP but generally it is not user controllable.
• VMSes vary significantly in what configuration or control they support for TCP or UDP.
• There are minimal latency differences between TCP and UDP on a dedicated network.
• In IP video, TCP and UDP may perform similarly in dedicated surveillance networks, as error correction and its associated overhead are less likely to come into play.
There are differences between TCP and UDP which make each more or less suitable to certain purposes. Some key differences are outlined below.
