Security industry has become a trend of high-definition, I believe we have many people have used high-definition network cameras, then what advantage does it have, ultra-clear, almost complete; save, wiring is simple. However, there will be a slight delay. Before many people touched the HD camcorder, they would shake their hands in front of the camera to see if the picture was smooth and there was no delay.
Delay is one of the important indicators of HD network cameras. To solve the problem of HD network camera latency, first of all, we need to know how the delay is generated: The following lists several important factors that cause HD network camera delays.
1. High Definition Network Camera (HDNC) video capture and encoding output takes time.
Second, when HDNC-encoded digital signals are transmitted through the network, network delays may occur depending on the bandwidth capacity and performance of the network devices.
Third, after the back-end device receives the encoded digital signal, it needs time to decode it.
Some netizens think that there is no point in delaying feelings, but if an accident occurs, it is because that short delay may have serious consequences and will not achieve the effect of prevention. What is the significance of monitoring?
Since the development of technology, there has been great technological progress compared to the millions of HD delays two years ago. If there is a decoder on the back end, it will also have decoding delay, poor preview device performance, and preview delay.
The delay of the webcam is definitely going to be, but it is really a long way to go without delay. Generally about 0.5S can be accepted, if you want to solve the delay, it will be difficult to break through for a few years, and the technical bottlenecks need to be overcome.
