The pan tilt thermal imaging device usually refers to a large-scale monitoring equipment that integrates infrared thermal imaging modules and intelligent pan tilt, often paired with high-definition visible light cameras. It has the characteristics of monitoring, accurate temperature measurement, and adaptability to harsh environments, and is widely used in large-scale, long-distance security and industrial monitoring scenarios. The pan tilt thermal imager uses a thermal imaging detector to receive infrared radiation emitted by an object, converts it into electrical or digital signals, and then generates visible thermal images through signal processing and image processing techniques. The intelligent gimbal can be driven by a motor to achieve horizontal and vertical rotation, thereby expanding the monitoring range.
Composition and working principle
Thermal imaging unit: The core is mostly an uncooled focal plane microcalorimeter, which can capture infrared radiation in the 8-14 μ m band, convert temperature differences of objects into electrical signals, and reproduce them into thermal images. It can also present temperature distribution through various color palettes such as white hot, iron red, rainbow, etc., making it convenient to identify targets in different scenarios. Some models use 12 μ m level detectors for higher imaging clarity.
Intelligent gimbal unit: driven by a motor, supporting continuous horizontal rotation of 360 ° and wide range vertical angle adjustment. Some products can reach a vertical angle of -20 ° (overhead) to+90 ° (overhead), and can achieve automatic cruise control, preset point positioning and other operations through remote control or preset programs, ensuring no blind spots in monitoring. At the same time, the gimbal can automatically adjust the rotation speed according to the lens focal length, ensuring stability when tracking targets.
Auxiliary module: Most products integrate high-definition visible light cameras, support optical zoom, and are equipped with white light fill lights; It also has data transmission interfaces and intelligent algorithm modules, which can achieve functions such as temperature measurement data storage and abnormal alarm.
Application scenarios
Industrial and power monitoring: It can monitor equipment such as substation transformers and switchgear, quickly locate overheated components, and prevent faults such as circuit short circuits; It can also be used for temperature inspection of equipment in warehouses and industrial areas to identify fire hazards in advance.
Security and Public Domain: Suitable for border defense, airport perimeter, urban high-altitude observation and other scenarios. Illegal intrusion targets can be captured through thermal imaging at night or in adverse weather conditions; In forest fire prevention, it is possible to quickly identify fire points and issue alerts in a timely manner through smoke and fire detection algorithms.
Maritime and special monitoring: can be used for identifying targets such as ships and floating objects at night in maritime monitoring; It can also cooperate with robot inspections to complete regular monitoring of large factory areas, remote pipelines, and other areas that are difficult for humans to cover.
