FIG11 is a schematic structural diagram of a server according to Embodiment 2 of the present invention  FIG12 is a schematic structural diagram of an IP camera control system according to an embodiment of the present invention 
FIG11 is a schematic structural diagram of a server according to Embodiment 2 of the present invention. As shown in FIG11, the server provided by this embodiment of the present invention includes a receiver 1101 and a transmitter 1102. Further, in the embodiment shown in FIG11, the transmitter 1102 is further configured to send first heartbeat information to the IP camera, where the first heartbeat information includes a communication address and a port number of the server, so that the IP camera constructs, according to the first heartbeat information, a heartbeat packet to be transmitted between the IP camera and the server. Further, in the embodiment shown in FIG11, the receiver 1101 is further configured to receive status update notification information sent by the IP camera, where the status update notification information is used to notify that a status of the IP camera is updated to the standby state. Further, in the embodiment shown in FIG11, the receiver 1101 is further configured to receive a wake-up instruction sent by the client, where the wake-up instruction includes the port number and the communication address of the IP camera to be woken up.  FIG12 is a schematic structural diagram of an IP camera control system according to an embodiment of the present invention. As shown in FIG12, the system includes a battery 1201, an IP camera 1202 according to any one of the foregoing embodiments, and a server 1203 according to any one of the foregoing embodiments.

['1. An Internet Protocol, IP, camera control method, comprising: receiving, by an IP camera, a standby instruction sent by a server; switching, by the IP camera, from a working state to a standby state when receiving the standby instruction from the server, the standby state comprising powering off a security chip and an image sensor of the IP camera; constructing, by the IP camera, a heartbeat packet to be transmitted between the IP camera and the server when in the standby state; sending, by the IP camera, the heartbeat packet to the server at a first preset frequency to make the IP camera maintain a heartbeat connection to the server; receiving, by the IP camera, a wake-up instruction from the server; and switching, by the IP camera, from the standby state to the working state when receiving the wake-up instruction from the server, the working state comprising powering on the security chip and the image sensor of the IP camera.']
