The wireless monitoring screen is not clear? It turned out to be these reasons!

The wireless monitoring system has been widely used in the security field, but there are still some problems such as unclear transmission images, stuck, and lost images, which brings certain resistance to the later playback, investigation and research. Because of this, image quality has become an important technical indicator of wireless monitoring systems. So, what are the reasons that affect image quality, and how should we solve it? The following Tengyuan Zhituo Xiaobian is based on years of wireless monitoring industry experience. List.

1, the quality of the camera itself

The difference between a network camera and an analog camera is that the network camera not only captures images, but also compresses the images before transmitting them. The quality of the image is related to the choice of front lens, image sensor and compression chip.

The resolution of the network camera, the quality of the lens, and the adaptability of the system to low ambient illumination all have an impact on the image quality of the system. The higher the resolution of the camera, the sharpness of the image will definitely be much better, but the higher the definition, the higher the bandwidth requirements of the wireless monitoring device.

2, the quality of the transmission cable

Although it is wireless monitoring, a small number of network cables are used in the whole system, and the quality of the network cable directly affects the quality of the monitoring picture. At present, most cameras are high-definition, so the ordinary network cable is used to build a video surveillance system, and the signal attenuation will be large. Therefore, it is necessary to use more than five types of network cables for transmission, so as to ensure that the image quality of the front end is transmitted to the monitoring center without attenuation, and the stability of the video signal is ensured.

3. Quality of wireless monitoring equipment

The quality of wireless monitoring equipment is an important factor affecting the quality of its transmission picture. The anti-interference ability of the wireless monitoring equipment when transmitting signals and the size of the bandwidth can affect the quality of the final receiving end image. Good quality wireless monitoring equipment not only ensures the stable transmission of video signals, but also has good anti-interference ability, so that the signal is protected from electromagnetic waves during transmission. Avoid image sticking, sometimes presence or not. Therefore, in the entire wireless monitoring system, the quality of wireless monitoring equipment is a top priority.

4, the impact of the switch on image quality

The switch is easily overlooked. Many people think that the switch is just a data exchange function. It does not need any processing on the signal. It can be equipped with a switch, regardless of the configuration of the switch itself. This is an incorrect statement.

If the data of the front end is relatively large, you must consider the bandwidth of the backplane of the switch and the forwarding rate of the packet. If the switch does not meet the transmission requirements, data jam may occur after running for a period of time, resulting in failure to receive the signal from the front end.

5, the impact of voltage on image quality

All devices in the entire system require power to work. If the camera voltage is unstable, the image will appear rippled. The unstable voltage of the wireless bridge will cause the signal strength to weaken and the image to be unstable in some cases. The long-term effect will affect the service life of the wireless monitoring device. Therefore, we must ensure the stability of the power supply voltage.

The above is the analysis of the reasons for the unclear picture of the wireless monitoring system. In the actual project implementation process, Tengyuan Zhituo technicians will design a set of the most suitable wireless transmission scheme for the user according to the site environment and user needs. Guarantee high-definition transmission of video images.
