FIG. 1 shows a schematic diagram of a video surveillance system according to an embodiment of the application. As shown in fig. 1, the video monitoring apparatus 100 may include a network camera (IPC) chip 110, a first network card 120, a network camera chip 130, a second network card 140, and a unidirectional optical module 150.

The network camera chip 110 can perform operations such as video capture and encoding to obtain video data.

The unidirectional optical module 150 may be various optical hardware modules capable of unidirectional data transmission. Here, the unidirectional optical module 150 may be replaced by another transmission method capable of unidirectional data transmission, which is not limited in the present application.

The transmitting end of the unidirectional optical module 150 is coupled to the network camera chip 110. In one embodiment, the transmitting end of the unidirectional optical module is connected to the network camera chip 110, for example, in a GPIO pin manner. The receiving end of the unidirectional optical module 150 is coupled to a Network Video Recorder (NVR) chip 130.

In summary, the network camera chip 110 can transmit the video data to the network camera chip 130 through the unidirectional optical module 150. The video monitoring apparatus 100 can implement unidirectional isolation between the network camera chip 110 and the network video chip 130 through the unidirectional optical module 150.

The first network card 120 is coupled to the webcam chip 110. The second network card 140 is coupled to the network video chip 130. In one embodiment, the webcam chip 110 is communicatively coupled to the first network 200 via a first network card 120. The network video chip 130 is communicatively coupled to a second network 300 via a second network card 140. In this way, the network camera chip 110 can provide video services to devices in the first network 200. The network video recorder chip 130 may provide video services to devices in the second network 300. For example, the first monitoring management device 210 in the first network 200 may preview and acquire video data collected by the network camera chip 110. The second monitoring management device 310 in the second network 300 can preview and acquire the video data in the network video recorder chip 130.

In one embodiment, the first network 200 is a local area network, and may be deployed in various application scenarios such as a bank, a stock exchange center, a big data storage center, and the like. The second network is for example a local area network other than the first local area network. The video monitoring apparatus 100 of the present application can provide video data services to apparatuses in the first network 200 and the second network 300, and can ensure isolation of the first network 200 and the second network 300. In short, the video surveillance apparatus 100 of the present application can simultaneously provide video data to two networks isolated from each other.

The receiving end of each unidirectional optical module 150 is coupled to a vcr chip 130. Each network video recorder chip 130 is communicatively coupled to a second network 300 via a second network card 140.

To sum up, the video monitoring apparatus 100 can transmit video data to the two network video recorder chips 130 through the switch chip 160 by arranging the switch chip 160. On this basis, the video monitoring apparatus 100 can provide video data to the first monitoring management apparatus 210 in the first network 200 and the second monitoring management apparatuses 310 in the 2 second networks, and can ensure isolation of the first network 200 from the two second networks. Here, the embodiments of the present application may maintain the isolation between the first network 200 and any one of the second networks 300, and may also maintain the isolation between different second networks 300. In short, the embodiment of the present application may provide video data to multiple networks (e.g., the first network 200 and the 2 second networks 300 in fig. 2) through one video monitoring apparatus 100, while ensuring multiple network isolation.
