I. Background of the Remote Monitoring System for Border Infrared Thermal Imagers
   As an important monitoring instrument for national defense security and border protection, the application background of the border infrared thermal imager is mainly reflected in the following aspects:
▲ Complex terrain: The border area encompasses various terrains such as high mountains, deserts, forests, and grasslands. In some areas, transportation is inconvenient and natural conditions are harsh, posing challenges to border security. In areas with dense vegetation such as high mountains and forests, the field of view of ordinary monitoring equipment is limited, but infrared thermal imagers can penetrate the vegetation and detect targets hidden within.
▲ Threat of illegal border crossing: Criminals often choose remote and poorly monitored areas along the border to illegally cross the border for activities such as smuggling, illegal border crossing, and espionage. Infrared thermal imagers can monitor the entire border in real time. Once a person's body heat signal appears, they can issue a timely warning, helping border guards quickly detect and intercept.
▲ Smuggling of goods: Smugglers may use vehicles, ships and other means of transportation to carry out illegal smuggling of goods at the border. Infrared thermal imagers can detect the thermal signals of vehicles and ships, enabling them to track their movements even at night or in concealed environments, providing support for combating smuggling.
▲ Potential military threats: Manual patrols are restricted by geographical conditions and the physical strength of personnel. Their patrol range and frequency are limited, and they are prone to omissions in bad weather and at night, making it impossible to achieve full-time and all-round monitoring.
The shortcomings of ordinary monitoring equipment: Ordinary cameras rely on visible light for imaging and need supplementary lighting at night. Supplementary lighting can easily expose the monitoring position and the effect is not as good as that of infrared thermal imagers. Under bad weather conditions, its imaging quality drops significantly, making it difficult to effectively monitor the target.
   The equipment features portability, stability, safety and long battery life under complex meteorological conditions. As for power supply guarantee, new energy lithium batteries, with their high energy density, long cycle life and environmental friendliness, have become the preferred solution for border defense infrared monitoring systems. This solution is aimed at the application requirements of lithium batteries in infrared monitoring equipment projects. Ensure that lithium batteries can provide safe, efficient and customized power solutions in special fields;
