A1. All objects in nature with a temperature above absolute zero (-273 °C) can radiate electromagnetic waves. When the IR radiation pass through the lens and reach the UFPA detector, the detector would convert radiation signals of different intensity into corresponding electrical signals. After being amplified and video processed, these signals would finally transfer to visible image.

A2. The traditional visible light camera may not be able to work properly due to the impact of the lighting and bad weather conditions, and problems like easy exposure may occur. By contrast, the thermal camera receives the thermal IR radiation of the target passively. It is able to detect human or vehicle normally in bad weather conditions (such as rain, snow, fog), and produce qualified image without much influence by climate/lighting.

A3. Based on strong environmental adaptability and high-precision video solutions, thermal cameras provide intelligent perimeters by combining with deep learning algorithm. Main application scenarios includes border and coastal defense, industrial infrastructure (refineries, factories, corporate parks, etc.), and civil close-up perimeter (high-end villas, museums, etc.).

A4. The most important point of fire prevention requirement is to detect high temperature targets and report alarm timely, which is exactly within the capability of thermal camera. There are different schemes for both indoor fire prevention (data center, electrical room, warehouse) and outdoor fire prevention (dumpsite, forest).

A5. Compared with previous or traditional fire prevention methods, thermal cameras can detect hidden fire danger earlier and report the alarm in time. The video output method is more intuitive and can record the cause of the accident for traceability.

A6. You could monitor the tiny temperature change and detect abnormal temperature of targets by setting temperature measurement rules in key areas. Application scenarios include electric power, manufacturing assembly lines, energy machinery monitoring, etc. It supports fire prevention and can also collect target temperature data and monitor the operation status of the target simultaneously to achieve the goal of process control. We also have different forms of products for different actual temperature measuring range and precision requirements.
