What is the difference between UDP protocol, TCP protocol, and HTTP protocol? PDF Print E-mail
The stability is HTTP >= TCP > UDP and the requirement of network bandwidth is HTTP >= TCP > UDP. You can depend on your network environment to choose UDP, TCP or HTTP.And we design a "protocol rolling" function to change your protocol automatically from UDP to TCP or from TCP to HTTP in case your network bandwidth is not stable.Besides, if you do not forward the TCP/UDP port on your router for the camera, the protocol will be changed to HTTP protocol automatically when you access the camera via Internet from outside.
