wireless bridge network camera
The wireless bridge played an important role in the use of the network camera. For example, in elevator video surveillance, the wireless bridge can be used to transmit the surveillance video data of the network camera. In terms of installation, the elevator bridge comes with a POE power supply. The POE port on the power supply can be connected to the POE port on the equipment using the network cable to supply power to the equipment. The computer room side (receiver side)'s POE power supply Lan port (or the device's Lan1/Lan2 port) can be connected to the local area network switch, and the camera side (transmitter side)'s POE power supply Lan port (or the device's Lan1/Lan2 port) can be connected to the IP (network camera) and other devices at the same time. When installing, the black case is connected to the switch or NVR on the computer room side, and the white case is connected to the IPC on the camera side. During networking, the bridge at the end of the elevator car needs to be set to client mode to convert the video data of the network camera from electrical signals to wireless signals; the bridge at the end of the elevator shaft is set to AP mode to connect directly with the NVR through the network cable, and the received wireless signal is directly converted into a wire signal and transmitted to the NVR. And before installing it in the elevator shaft, the bridge had to be matched in advance. At the same time, in order to ensure the transmission quality, it was necessary to avoid the interference of environmental factors as much as possible. During installation, it was necessary to ensure that the bridge was installed directly to avoid the obstruction in the middle of the bridge. The installation position should not be close to the corner of the wall as much as possible to avoid the interference of multi-path reflection on the signal. In the connection part of the equipment, such as the network bridge, the network cable connection part of the POE and the network camera, it needs to be waterproof and dust-proof. The connection part of the network cable and the network bridge generally needs to be wrapped with two to three layers of waterproof tape. The connection part of the network cable and the network camera also needs to be wrapped with two to three layers of waterproof tape or insulated tape. All the power connections should be insulated as much as possible. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
