In recent years, with the development of the social economy, some "undesirable elements" have engaged in illegal activities such as smuggling to achieve the goal of "quick wealth accumulation". Some ship crew members also fail to follow the regulations when operating navigation lights. The increase in illegal acts of ships, such as smuggling, overloading, and operating without following the designated navigation channels, has also increased the burden on the maritime law enforcement agencies - the maritime administration. At the same time, if a normally operating ship encounters an accident and the maritime administration needs to carry out rescue operations, it also requires real-time dispatch and command. Therefore, maritime law enforcement is not merely law enforcement; it has a service-oriented nature. It faces problems such as the complexity of administrative counterparts, difficulties in obtaining evidence through manual law enforcement, command and dispatch, and low law enforcement efficiency.

        The waters under the jurisdiction of a certain maritime administration are one of the busiest waterways for maritime traffic in our country, and also a frequent area for ship accidents. The construction of a wireless video monitoring system can enable the rescue center to promptly view the real-time transmitted on-site images, allowing the supervisory personnel to promptly and intuitively understand the dangers on the scene, helping them to correctly judge the nature and severity of the danger, and based on the current resource allocation and environmental conditions, proposing multiple rescue plans according to the predetermined procedures and norms for decision-makers to choose, effectively reducing and avoiding decision-making errors, and improving the effectiveness of rescue command.

        The maritime law enforcement vessel video monitoring system solution is designed to meet the work requirements of maritime law enforcement for evidence collection and emergency command. It provides a maritime law enforcement vessel video monitoring system that integrates high-definition video monitoring technology, remote wireless transmission technology, and portable single-person technology. This system can not only enhance the maritime law enforcement capabilities, create a law enforcement deterrent, enhance the awareness of ship operators to navigate in compliance, reduce illegal navigation behaviors of ships, ensure the safety of people and property on the water, but also improve the law enforcement image of the maritime law enforcement team and form an efficient and orderly maritime supervision and law enforcement mechanism.

        Recently, at the invitation of the relevant departments, our company brought the independently developed COFDM mobile video wireless transmission equipment to the site for a distance test of wireless transmission. The front end of the equipment was installed on the law enforcement vessel, while the receiving end was set up on the rooftop of a small hilltop sea affairs base on the shore. After the equipment was set up, the law enforcement vessel began to leave the port to carry out normal tasks. During the 3-hour period when the law enforcement vessel was performing its tasks, the straight-line distance traveled exceeded 20 kilometers. The high-definition video received at the receiving end was clear and stable. The equipment achieved the expected effect, and the customer was very satisfied with the test results.

        The following are the pictures from the on-site test:
