Because the remote place does not have the commercial power supply, the solar cell panel is selected as the equipment power supply in this embodiment for supplying power for the camera. The solar cell panel can provide stable current, and the operation and maintenance is simple. In some other embodiments, lithium batteries can be used to supply power, and only need to be replaced and charged periodically, and of course, in channels with high flow rate, a small hydroelectric generator can be arranged to supply power.

It will be appreciated that there are many types of wired ports that can be used to accommodate a particular camera model, and that currently, most cameras are commonly adapted to RJ-45 ports. The wired network port is used as a data transmission interface of the camera and is also used for providing power for the camera, therefore, the power of the camera is also uniformly managed by the gate controller, when a user needs to check the gate image video, the gate control module controls the power of the camera to be turned on, and the camera is in a dormant state in other time, so that the electric energy is saved, and the operation and maintenance cost is reduced.

Referring to fig. 6, when there is a cloud server, an activation command sent by a video terminal first reaches the cloud server, and the cloud server forwards the activation command to the gate controller. In this embodiment, the activation command of the cloud server first arrives at the wireless network module, the wireless network module transmits the activation command to the gate control module, and the gate control module recognizes the activation command and then controls the power management module to be connected with the power supply of the device, so that the power supply of the camera is turned on, and the camera starts to shoot the picture of the environment around the gate.

In this embodiment, a technician sets when the video terminal sends the activation command through a program of the APP or the client, for example, may set that the user sends the activation command when opening the APP, or sends the activation command when the user logs in successfully. Since video transmission needs to be completed when the camera is powered on, in this embodiment, the camera is turned on before the camera receives the data transmission request.

Optionally, when a user clicks one or more video windows corresponding to the gate in the gate video APP, the APP sends an activation command and a video viewing request to the gate controller, the gate control module reads the activation command and the video viewing request, the power management module is controlled to start the power of the camera and open the NAT forwarding function of the Linux kernel, and then the video request is sent to the camera. Of course, the video activation command and the video viewing request can be simultaneously sent to the gate control module, and the gate video APP can also be set to send only one signal, namely, the video viewing request is also the video viewing request as the activation command, at this moment, the gate control module simultaneously opens the camera, activates the NAT, and transmits the video viewing request to the camera.

It should be noted that, in this embodiment, the gating module receives the activation command and then has multiple response actions, and this embodiment does not limit the order of the response actions, nor the simultaneous response, that is, starting timing, powering on the camera, and turning on the NAT may occur simultaneously or sequentially.

Optionally, the gate control module may be configured with a timing function, and start timing when receiving the activation command, and control the power supply of the camera to be turned off if the activation command is not received after a certain time limit is exceeded, and at the same time, close NAT forwarding, reduce power consumption of the camera and the gate controller, and further reduce power consumption. Under general conditions, have a plurality of users to use gate video APP simultaneously, consequently, if the incessant activation order of receiving of gate control module, can control the camera power and open always, NAT forwards the function and also is in the open mode always, guarantees the transmission that the video can be stable.
