The dual-spectrum long-range thermal surveillance camera is designed for border patrol, coastal monitoring, perimeter protection of critical facilities, industrial park security, remote field surveillance, and other applications requiring continuous all-weather monitoring. It enables long-range day/night observation of personnel, vehicles, facilities, and other targets. By combining low-light long-focus imaging with thermal imaging, the system can continuously acquire target information in challenging conditions such as dust, smoke, rain, snow, and darkness. It also integrates image processing, lens management, and servo control, with an IP66 protection rating for long-term outdoor deployment. The observation range reaches up to 10 km during the day and 3 km at night, with 360° horizontal coverage and a pitch range of -45° to +45°.
