Hundreds of monitoring points to establish wireless monitoring recommendations

Normally, the number of wireless monitoring projects we do is generally a wireless monitoring system with several to several tens of points. Hundreds are also relatively few. For some sites, such as large-scale factories, roads, large-scale farmland, etc., cameras that need to be installed are relatively dense and relatively large, and may reach hundreds or hundreds. In this case, how to do a wireless monitoring system?

We all know that wireless bridges have a certain frequency, and not infinitely many can be networked. Based on actual experience, we give the following suggestions:

1, close to the camera focus

Look at some of the nearby cameras can not be concentrated. For example, some factories are surrounded by a row of cameras that can be used to wire up the row of cameras and launch them through a wireless bridge.

2, point-to-multipoint transmission mode

If so many points are within 5 kilometers, they can be networked in a point-to-multipoint manner. Point-to-multipoint mode should pay attention to the video stream of the camera, and several pairs of one receiver should pay attention to the demand bandwidth. If the distance is too far, using point-to-multipoint is a bit difficult because the farther the transmission distance is, the angle of the wireless bridge is generally very small, and it is difficult to match multiple pairs, plus the bandwidth consumed when the transmission distance is far greater. Many.

3. Multiple receiving stations can be set up. The signal from the receiving station is then transmitted to the computer room.

If there are a few hundred points, it may not be very realistic for all to be sent to a computer room. Can do several receiving stations, dozens of monitoring points of the signal first transmitted to the receiving station, from the receiving station depending on the camera's digital, pixel size, high-bandwidth wireless bridge can be used to transmit the signal to the engine room.
