To ensure the safety of passengers, various detection instruments are installed at security‑check points such as subway entrances and exits, high‑speed railway stations, train stations and airports. These devices help prevent people from carrying hazardous articles on their persons or in backpacks. Such dangerous goods may not only endanger people’s health and personal safety but also compromise the operational safety of transport vehicles. How should you pick a reliable infrared thermal imaging device to safeguard public safety? The specialists from Kaimorui offer the following guidance.

Selection Guidelines for Infrared Thermal Imaging Devices

Resolution: The mainstream resolutions for commercial infrared thermal imagers are 384×288 and 640×480. Higher resolution is preferred if budget permits.

Thermal Sensitivity: As a key parameter of infrared thermal imagers, thermal sensitivity refers to the minimum detectable temperature variation. For standard‑grade devices, thermal sensitivity is ≤0.05 ℃ at 30 ℃.

Complete Accessory Support: If the thermal imager needs to be mounted in a fixed position for measurement, corresponding supporting accessories are required. Adequate accessories are also essential for deployment in alternative operating environments.

Temperature Stability: The core component of an infrared thermal imager is its infrared detector. The two primary types available on the market are vanadium‑oxide and polycrystalline‑silicon detectors.

Keep the above‑mentioned key points in mind when determining the most suitable infrared thermal imaging device for your application. Importantly, do not base your choice on a single parameter. Make a comprehensive evaluation aligned with your actual requirements.
