So how does the delay of the wireless monitoring system come about? What method can be used to minimize the delay? This is often a problem that many engineering companies are most concerned about. The following Shenzhen Leian Technology Xiaobian to briefly explain:
1, the delay of the camera itself to delay the traditional analog camera is relatively small, but for the HD network camera, the signal delay is much larger. Because the HD network camera has a built-in encoding function, the camera signal is encoded by the encoder into a digital signal before transmission. In this coding process, the signal will have a certain delay, and the size of the delay depends on the quality of the code board.
Therefore, the choice of camera is also very important. The coding technology used by each brand camera is different, so the delay is not the same.
2. Network DVR Delay The network DVR is equipped with a video decoding function, and the quality of the decoder board 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. When you choose a network hard disk recorder, you must consider the compatibility with the camera. The codec board is an opaque protocol. The codecs of different manufacturers are incompatible. Even if they can be used, the delay is very large. Therefore, if you want to reduce the delay camera must be paired with the network hard disk recorder, we must choose the same manufacturer's products.
3, the delay of the switch When the network traffic becomes larger, the processing time of the switch and the router becomes longer, and the delay of the poor quality switch, packet loss rate, backplane bandwidth, switching capacity, packet forwarding rate and other factors It will also be directly reflected in the process of network transmission, so controlling network traffic and selecting quality switches is an effective means to reduce the delay.
4, network cable delay As we all know, a good network cable and a bad network cable, naturally, a good network cable transmission efficiency is higher, and prone to delays and other adverse effects is a bad network cable, so choose a good transmission equipment It is an important measure to reduce the delay; when the cable is transmitted, it is naturally a network cable, and in the wireless video transmission, a high-quality wireless video transmission device is selected.
5. Delay of wireless video transmission equipment The CPU processing capacity of the equipment responsible for the transmission or the speed of the system reaction is not fast enough, resulting in a delay in the transmission process. A wireless video transmission device is also similar to a computer, and its delay size also has a certain relationship with the configuration of the device itself and the hardware chip. Therefore, we must look at the configuration of the wireless video transmission device, such as memory, flash memory, and programs. The biggest difference between cheap wireless bridges and high-quality wireless bridges is that in these areas, the response speed and signal processing capability of a good wireless bridge will be much faster, and then the delay will be much smaller. The delay of wireless bridges produced by Shenzhen Leian Technology is generally within 10 milliseconds.
6. Delay of relaying of relay devices of wireless monitoring equipment:
In the transmission process, each jump once represents an increase in the processing time of the relay device. Therefore, the greater the number of jumps, the greater the time loss. Therefore, reducing the number of hops in the design of the transmission line effectively reduces the delay. A complete wireless monitoring system, we want to minimize its delay, we should consider from these aspects, try to use the wireless monitoring system for your peripheral products.

In the analog wireless monitoring system and the high-definition wireless monitoring system, it is often encountered that the video appears stuck and the picture is delayed, which is caused by the signal delay. The signal delay can not be avoided, ranging from a few milliseconds to as many as several tens of milliseconds. Even some device delays can reach one or two seconds.
