Wireless bridges are best for one-to-one connections, with the best loss and best data transmission. However, when there is a need for one-to-many at some times, there are some issues that need attention. Feng Runda, a professional wireless bridge and solution provider, summarized the following points for reference.
1, to ensure that one-to-many wireless transmission must use a webcam, traditional analog devices can not do one-to-many transmission, but only suitable for one-to-one transmission.
2, one-to-many, as the name suggests to correspond to multiple transmitters, and the transmitter is usually connected to the front camera. When designing a one-to-many system, it must be noted that the angle between the two transmitters should not be too large, and it is usually kept at about 20 degrees. In addition, the transmission distance between the transmitting end and the receiving end of the front end cannot be too far. Sometimes, due to environmental restrictions, it is necessary to be too far away. At the very least, the transmission link must be ensured on the same line. Otherwise, the stability of the transmission picture quality cannot be ensured.
3, when doing one-to-many, naturally consider the issue of transmission bandwidth. When using a camera, it is better to plan what pixel camera is appropriate. After all, if the wireless bridge's own transmission rate is not so large, if the pixels of the camera are too large, it will easily cause the transmission to be unstable and even unable to fully transmit the scene.
4, if the distance between the monitoring points are relatively close, the transmission distance is less than 800 to 1000 meters, consider omnidirectional reception.
5, when one-to-many, the wireless bridge requests the channel to be the same when setting up, and input the MAC address of each other in WDS, and close the DHCP service of B router.
The above is a few things that need attention in the setting of one-to-many wireless bridges. It is not difficult to understand it. In general, it is necessary to pay attention to the transmission distance and the transmission bandwidth, and the smoothness of the transmission channel. The problem, of course, is the flexibility to adopt a variety of appropriate equipment based on site conditions.
