A network monitoring apparatus, and a remote encryption and remote activation method, device and system thereof are provided. The method includes the following steps: receiving an encrypted activation password sent by a client terminal; decrypting the encrypted activation password to obtain an original activation password; determining whether the original activation password meets a predetermined password strength requirement; when the original activation password meets the predetermined password strength requirement, activating the network monitoring apparatus and setting the original activation password as an administrator password; and returning information indicating that the network monitoring apparatus is successfully activated to the client terminal. A network monitoring apparatus, an encryption method of a network monitoring apparatus based on a client terminal, a client terminal, and a remote activation system based on a network monitoring apparatus are also provided. The present disclosure combines an asymmetric encryption mode and a symmetric encryption mode, so as to enhance a security of an activation process.

A method, a server and a system for calculating bandwidth of UDP-based streaming media network transmission. The method includes: dividing video frame data to be sent into a plurality of sub-video frame packets, sending a sub-video frame packet with a preset serial number to a client, and receiving a response message sent by the client, wherein the response message includes a first serial number and a second serial number; sending a sub-video frame packet corresponding to the first serial number to the client, and determining whether the client has received all sub-video frame packets of the video frame data; if so, accurately calculating the actual bandwidth of the current network based on the sending start time of the first sub-video frame packet of the video frame data, the sending end time of the last sub-video frame packet of the video frame data and the size of the video frame data, which provides a basis for the self-adaption of the encoding rate.
