20 km mobile video wireless transmission test

In recent years, with the development of society and economy, some "illegal elements" have engaged in illegal activities to achieve "quick gains"; some ship drivers have not navigated lights as required. The increase in illegal acts such as ships, overloading, and failure to follow the prescribed waterway will also increase the pressure on the maritime authorities, the Maritime Affairs Bureau. At the same time, if an accident occurs in a ship that is operating normally, the maritime department will need to carry out real-time dispatching and commanding. Therefore, maritime affairs are not pure, but are of the nature of service. They are confronted with problems such as the complexity of administrative counterparts and manual verification, difficulties in command and dispatch, and low efficiency.
The waters under the jurisdiction of a maritime authority are one of the busy water areas for water transportation in China and are also frequent areas for ship traffic accidents. The construction of a wireless video surveillance system enables the search and rescue center to see real-time transmission of live images in real time.
The management personnel timely and intuitively understand the dangerous situation on the scene and help the competent personnel to correctly judge the nature and danger degree of the dangerous situation. According to the existing resource allocation conditions and environmental conditions, a number of search and rescue plans are proposed for decision makers according to predetermined procedures and specifications. Reduce and avoid mistakes in decision-making and improve the effectiveness of search and rescue command.
Maritime Vessel Video Surveillance System Solution Aiming at the maritime and emergency command work requirements, a ship video surveillance system that integrates high-definition video surveillance technology, long-distance wireless transmission technology, and portable soldier technology can enhance maritime capabilities, create deterrence and enhance The ship operators’ awareness of compliant navigation, reduction of illegal navigation of ships, and the safety of personal and property on the water, can also enhance the image of the maritime team and form an efficient and orderly maritime supervision and mechanism.
Recently, at the invitation of related departments, our company has independently developed COFDM mobile video wireless transmission equipment to the site for wireless transmission distance testing. The front end of the equipment is installed on the ship and the receiving end is erected on the roof of a maritime base on the top of a small hill. After the installation of the equipment is completed, the ship begins to go out of port for normal tasks. Within 3 hours of the mission of the ship, the straight-line distance of more than 20 kilometers. Receiver HD video reception is clear and stable. To achieve the desired effect of the equipment, the customer is very satisfied with the test results.
