WiFi module long distance low - latency picture transmission wireless transmission

2022-10-20 811

In the wireless transmission system, the factory wireless transmission is becoming more and more common and important. It can effectively protect the fixed assets of the factory, improve the work efficiency, enable the management to understand the situation of the factory faster, and make decisions in a timely and decisive manner. At the same time, ensuring the safety of employees' lives and property is an indispensable responsibility of the factory. By installing a surveillance system in the factory, the main entrance and exit of the factory can be seen through the camera in the factory floor, so that criminals can be found in time. The video recorder can also be turned on as evidence, which will also play a certain deterrent role to those who have bad intentions.

WiFi module long distance low - latency picture transmission wireless transmission

1.WiFi module long-distance low-latency graph transmission wireless video surveillance data transmission rate can reach 108Mbps;

2. Wireless network transmission system with high efficiency, low cost and high stability;

3. Superior wireless environment, no need to lay cables, no need to rent lines;

4. Simple Web management functions for wireless configuration, maintenance, and remote configuration;

5. The network can be in 2.4GHZ/5.8GHZ frequency band;

6. Adopt IEEE802.11 a/b / 802.11 802.11 g standard.

7. Virtual private network (VLAN), FIREWALL, MAC access control, connection peer to peer encryption (WEP), 802.1x technology (port access control), network encryption machine to make the network has outstanding security features, can prevent hacker attacks, data theft and malicious intrusion.


The site is a large foreign enterprise factory, which requires 24-hour real-time monitoring of the warehouse, workshop, workers' dormitories and video images of all the factories at the factory gate. A total of 14 monitoring points, the front-end adopts high definition ball machine, 2 km away from the monitoring room. In order to effectively and stably transmit signals to the monitoring room, we use digital WiFi module to monitor multiple points with low delay and realize the monitoring of the whole wireless system.


Since the customer uses high-definition surveillance cameras, we transmit them in the form of one-to-many. The front end connects the high-definition camera with a digital network bridge at 13 o 'clock, and the back end receives the long-distance low-latency image transmission from four WiFi modules, which enters the switch and then accesses the computer. One of the points is blocked to the monitoring room. The principle of wireless transmission is to carry out without blocking, so we need to first transmit the blocking point to the next place for receiving and then transmit to the monitoring room with a bridge. Access the switch and then the computer.


Make full use of the advantages of WiFi module long distance low delay image transmission wireless video monitoring system, combined with advanced computer technology, to achieve monitoring image transmission and remote monitoring, to provide efficient, feasible, low-cost solutions. It provides more effective management means for factory management and more powerful technical guarantee for the safety and efficient management of enterprises.


School, campus WiFi module, low latency chart spread over a long distance wireless transmission scheme, campus monitoring system is more and more important in today's society, the campus safety has become one of the most area of concern in society, through the establishment of a wireless video monitoring alarm system, monitoring and school environment around the school, to prevent invasion of criminals and trafficking, illegal activities such as theft, robbery, To ensure the safety of life and property of students and staff. Local governments have gradually included anti-campus surveillance in urban public security surveillance.


1. The application of WiFi module long distance low delay image transmission

1. Small and difficult wiring environment

In many cases, cables cannot be easily laid; Such as: historical buildings, old buildings, open areas, rivers, rivers, busy streets, construction sites, mining areas, mines, tunnels and other lines can not be reached or the construction cost is very expensive

2. Temporary office space

In parks, stadiums, exhibition centers, disaster relief sites, temporary offices and construction sites, it is hoped to establish temporary WiFi module remote low-delay picture transmission wireless communication network or temporary video surveillance, which can be removed at any time and used in the next place.

3. A place that changes the layout of the environment frequently

Exhibition halls, conference rooms, retail stores, production sites and other places where the layout changes frequently


Second, customer site analysis

According to the project requirements, it is necessary to use high-definition surveillance cameras to control key parts of the school, monitor passing vehicles and people in and out in real time, and effectively deal with the site. It is necessary to carry out wireless remote monitoring at the school gate, playground, activity center, canteen, teaching building, laboratory and other key parts. The WiFi module remote low-delay image transmission monitoring system has a total of 20 monitoring points with a transmission distance of 2km. In order to realize the effective and stable transmission of signals to the monitoring room, we use wireless digital network bridge point for multi-point monitoring, and realize the monitoring of the whole wireless system.


Third, wireless transmission solutions

The principle of wireless transmission can only be achieved without blocking. The customer asked for a web HD camera. We transmit in one-to-many format. The front 20 points were connected to HD cameras by WiFi module long distance low delay image transmission, but the 6 monitoring points were blocked to the monitoring room. Therefore, we need to transmit the six barrier points to the nearby high roof, which is received by the digital network bridge, and then transmitted to the monitoring room by the network bridge. The remaining 14 monitoring points are received in the form of a pair of four at the receiving end, access switches, and then into the network hard disk recorder or computer.


4. Campus WiFi module long distance low delay picture transmission wireless transmission system

Campus wireless transmission system for the school and parents to establish a sunny communication window, let teachers consciously regulate behavior, mobilize and play the enthusiasm of teachers, let parents understand the school platform, further understand the children's real campus life, for the education environment to provide a communication and protection platform.
