What to do if wireless video surveillance system delays
Wireless video surveillance systems are widely used in more and more projects due to their advantages of flexibility, simplicity, convenience, and low cost. However, one drawback of the entire system is the delay. If video is stuck and the picture is delayed during wireless video surveillance, this is undoubtedly the most unacceptable. With the development of modernization, the requirements for wireless surveillance are high-definition, real-time, and smooth.
There are several devices in the entire wireless video surveillance system, so it is impossible to achieve full real-time. But if you do it well, you can reduce the maximum delay almost equal to real-time. So, how should we minimize the delay?
1. Performance of Wireless Video Surveillance Equipment: In a wireless video surveillance system, wireless transmission equipment plays a crucial role. Good wireless bridges, what kind of wireless bridges on the market have, the price is also different, here, we recommend that you use the chip, hardware, software are stable equipment manufacturers, in other words, is to choose a high quality, stable wireless bridge . In this regard, Levin Wireless Bridge can be described as well-deserved.
2, on the performance of the transmission line: As we all know, a good network cable and a bad cable, is a good network cable transmission efficiency is higher, but prone to delays and other adverse effects is a bad cable, so choose High-quality transmission equipment is an important measure to reduce delays. For the connection of the network cable to choose the five or six types of network cable, do not want to be cheap, bought a poor quality cable.
3, on the transmission process of relay equipment jump effect: In the transmission process, each jump once, it represents an increase in the processing time of a transit device, so the more the number of jumps, resulting in greater time loss. Therefore, reducing the number of jumps in designing the transmission route can effectively reduce the delay.
4. Impact on decoder performance: A so-called decoder generally refers to the decoder itself or the client used for decoding if the client's host configuration. The quality of the decoder can easily affect the video decoding speed. If the quality is not good, video delay or card screening may occur. However, what needs to be explained here is that in the course of decoding or encoding, the system automatically adds buffering to maintain the fluency of the video, which is also prone to slight delays.
5, on the performance of the switch: When the network traffic becomes larger, the switch and the router's processing time will accordingly longer, and the poor quality of the switch's delay, packet loss rate, backplane bandwidth, switching capacity, packet forwarding Rates and other factors will also be directly reflected in the process of network transmission. Therefore, controlling network traffic and selecting high-quality switches are also effective measures to reduce the delay. It is better to monitor the dedicated switches.
