The on-site dedicated equipment box is a transfer device between the on-site image detector and the video host of the image fire detector.

The power supply line and network cable of the image detector should be connected to the corresponding terminal block of the dedicated equipment box on site.

The network cable of the on-site equipment box is converted into network optical fiber through the optical fiber transceiver and transmitted to the optical fiber transceiver receiving end of the video host.

The optical transceiver receiving end of the video host of the image fire detector converts the network optical fiber into a network cable and connects it to the network switch of the video host, providing long-distance network transmission.
