    15km LR-WIFI module wireless transmission on highway/road/large construction site


    1. Site Description:

    The site was a road surveillance project. Due to complex construction and inconvenient wiring, this project adopts wireless transmission, which requires real-time monitoring of road conditions 24 hours a day and 24-hour monitoring and video recording. There are 12 network HD cameras on site, among which two cameras are transmitted at 6 and 7 o 'clock. Since there are two obstacles in the transmission, we need to find a relay point. This relay point can not only see the transmitter or receiver, but also avoid obstacles through the relay and better relay the signal to the monitoring room.

    2. Customers' specific requirements for wireless video surveillance transmission equipment

    In order to further strengthen the traffic safety management of the main road, monitor the traffic conditions at each intersection, according to the specific requirements and characteristics of the urban road image monitoring demand, consider making full use of its internal resources and local network environment, combined with its management needs. This scheme proposes to adopt the 15km LR-WIFI module video and image centralized monitoring and management mode, with digital monitoring, video recording and management functions when implementing image points related to major road intersections. The 15km LR-WIFI module monitoring mode can make the relevant processing work of the traffic safety supervision department more convenient, fast and accurate, and ensure the rapid and timely response to emergencies.


    3. Design ideas of wireless video surveillance engineering scheme:

    According to customer demand, our company designed a set of advanced digital wireless video surveillance system. The whole system adopts industrial grade digital wireless video transmission of CSW2203 in 5.8G band and CV5200 in 2.4G band of 15km LR-WIFI module of our company.


    Wireless transmission scheme for large construction site

    1. Site Description:

    The site is located in the large construction site, the construction site needs 24 hours a day real-time monitoring. In order to ensure the smooth construction and equipment safety, the video surveillance scheme is used for 24-hour monitoring and video recording. Hd network gun should be installed on site, and 10 poles should be set up on the construction site. The customer needs to have a night vision of 80 meters (the customer needs to buy it by himself).


    It is transmitted to the local monitoring room about 5 kilometers to watch, and can be handled in time if there is an emergency. Considering the inconvenient cable for video surveillance transmission, vehicles at construction sites are prone to disconnection. Therefore, 15km LR-WIFI module wireless video transmission equipment is used for remote wireless transmission and wireless transmission of multi-channel high-definition video pictures.


    There are 20 ball machines in the field, 2 for each rod, and 2 for each rod can be summarized with a switch, so a launch can be summarized with 2 cameras. The rear control room is located 1km from the steel sheet house. When installing the 15km LR-WIFI module for wireless video transmission, it is necessary to adopt the wireless digital receiving device at the rear end to realize the transmission and reception without block. The receiving end can receive the signals from multiple transmitters summarized at the front end. Here, we plan to complete the transmission of 10-bar 20-channel video signal on the back end 1 to 3.3.4. To the back end, the switch summarizes the wireless receiver's signal into the storage device to the monitor.


    2. Customers' specific requirements for wireless video surveillance transmission equipment

    In order to strengthen the scientific construction safety construction, improve the efficiency of project management, prevent idle personnel from entering the construction site, resulting in safety accidents and property losses, the establishment of advanced video surveillance safety management system on the site. Due to the limitation of construction environment and equipment. The material safety management is not perfect, and some employees have weak self-protection consciousness, which is not suitable for the traditional wired monitoring method. However, the video monitoring system must be installed on site.


    3. Design ideas of wireless video surveillance engineering scheme:

    According to customer demand, our company designed a set of advanced 15 km LR-WIFI module wireless video surveillance system. The whole system adopts our company's 5.8G band 2203 industrial grade digital wireless video transmission module.


    The transmitter of each vertical rod in the front end is sent to the back-end monitoring room, and the receiving end of the monitoring room is received 1 to 3.1 to 3 to 4 to 4 to many. The output network cable at the wireless digital video receiving end is summarized by the switch, and transmitted to the NVR storage in the monitoring room for watching on the monitor. The NVR can control the rotation of multiple ball machines in the front section.
