Signal delay is an important issue in wireless surveillance systems. We know that it is impossible to achieve a complete monitoring system without any delay, because it is composed of many parts, each of which affects the transmission efficiency of the entire system. Therefore, what we can do is to minimize the delay. Below, Xiaobian will tell you how the wireless monitoring system should reduce the delay.
First of all, the wireless transmission accessories category, the so-called "wireless" is actually the function of the device instead of the intermediate cable, but the device still needs the network cable or video to connect the front-end camera and the back-end monitoring center equipment, and the middle cable is also an important part. A good cable can make the transmission more efficient, and the cable length is also required. Therefore, choosing a good quality connection cable is also an important measure to reduce the delay.
Secondly, it is well known that the wireless bridge transmission environment is transmitted without outdoor occlusion, but many projects are occluded in the middle, because many customers are not willing to set up too high and choose to adopt relay mode. However, each time it is relayed, it is necessary to increase the time of the transfer processing accordingly, so the more the number of jumps, the greater the delay of wireless transmission. Therefore, it is generally recommended to minimize the number of transfers when the height can be increased.
Third, there are many manufacturers of wireless video equipment on the market, and customers are often confused by surface parameters. In fact, to a certain extent, quality determines the price is reasonable. Therefore, the procurement of the pre-equipment equipment is also very important. The CPU processing capability of a good quality wireless monitoring device or the speed of system response is fast, which can reduce the delay phenomenon generated during transmission to a certain extent.
Finally, the small series is about the impact of the switch on the delay, the switch has hundreds of megabytes, gigabit choice. A good switch can process data faster when the data is transmitted. A poor switch, when the transmission data becomes larger, is prone to delays, packet loss and the like. Therefore, in the pre-engineering design, it is necessary to calculate the maximum value of the data that needs to be transmitted. Choose the right switch to avoid the possibility of data packet loss delay.
The above is related to how to reduce the delay level of the wireless monitoring system, more professional knowledge can be concerned about Tengyuan Zhituo, we will popularize more detailed wireless monitoring transmission knowledge for the majority of users.
