How does wireless monitoring save data?

Wireless monitoring is transmitted to the wireless monitoring center through wireless communication means, and automatically forms a video database to store data.

In the wireless monitoring system, the wireless monitoring center needs to obtain the video information of the monitoring point in real time, and the video information must be continuous and clear. In wireless monitoring points, cameras are usually used to collect the scene in real time. The camera is connected through video wireless transmission equipment and sends data signals to the monitoring center through radio waves.

The system is powerful, flexible, fully digital and easy to store and retrieve. According to the storage space of the monitoring center, the size, quality and frequency of image acquisition, video data can be recorded for several hours to several months. Users can play, locate, fast play and slow play recorded video data.

Extended data

The biggest advantage of arranging wireless monitoring system outdoors is that there is no big building block. Therefore, it is not necessary to think too much about the problem of wireless signals passing through the wall. The wireless network cameras in outdoor wireless monitoring systems are generally scattered, but the interference of some external signals should also be considered.

The establishment of external wireless monitoring system should be determined according to the distance between the wireless network camera and the monitoring center. If the distance between them is less than 400 meters (theoretical value), the monitoring signal can be directly received through the wireless AP in the monitoring center.

If the distance between the wireless network camera and the monitoring center is less than 1km, and a wireless AP can be added near the wireless network camera, then it is necessary to consider using a wireless bridge to realize data transmission. Using wireless bridge to establish a wireless monitoring system can theoretically monitor the 50km site as far as possible. If the monitoring distance needs to be longer, two wireless bridges can be placed back to back through the relay, which can extend the wireless signal transmission distance.

Indoor wireless monitoring system is different from outdoor wireless monitoring system. The wireless network cameras in the indoor wireless monitoring system are densely distributed with many points, which are blocked by walls. Even if a wireless AP is arranged, the signal coverage distance will not be too far. So the indoor wireless monitoring system will arrange more wireless access points in a small space.

Especially in some hotels, because of the floor design, it is necessary to arrange 1 or two wireless APS on each floor to cover the whole building. The signal of a wireless AP can basically cover every corner of a floor in an ordinary building.
