The invention relates to a wireless-network-based power monitoring security and protection integrated system. The system is characterized in that the system comprises a plurality of camera devices and a warning security and prevention device. The camera devices and the warning security and prevention device are connected with a master server by a wireless communication network; the master server is connected with a management server by a switch; the management server is connected with a backup server and a central controller respectively; and the central controller is connected with a display. On the basis of mutual combination of power monitoring and security and protection, monitoring is realized and an objective of security and protection is achieved. The integration degree is high. Moreover, with the monitoring cameras based on the design, the cameras can be controlled remotely and proper and precise monitoring can be realized; and the image transmission speed is fast.
