The invention relates to the technical field of intelligent camera communication protocol security, and discloses an intelligent camera, which comprises camera equipment CDsssd which runs deep packet inspection system server software and serves as Modbus slave equipment, and the camera equipment CDsssd is in communication connection with a remote client RCcmd through an industrial Ethernet and by adopting a Modbus/TCP protocol. Deep packet inspection system client software runs on the remote client RCcmd, and the remote client RCcmd is used as a Modbus main device; the deep packet detection system comprises an identity legality detection module, a protocol integrity detection module and a function code use security detection module. The camera equipment CDsssd authenticates whether the communication authority of the remote client RCcmd is legal or not through the identity legality detection module. According to the invention, the technical problem that an attacker will counterfeit a remote client RCcmd as a Modbus master device to maliciously access a camera device CDssd as a Modbus slave device due to the lack of a corresponding identity authentication mechanism in a Modbus/TCP communication process is solved.
