Protecting national borders is critical to a country’s security. However, detecting potential intruders or smugglers in unpredictable weather and completely dark surroundings is a real challenge. But infrared thermal imaging cameras can help meet the detection needs of border guards in late night and other low-light conditions.
Infrared thermal imaging camera can produce clear image in dark night without any other light source. Of course, thermal imaging is also practical in the daytime. It is not interfered by the sun light like the normal CCTV camera. Moreover, its thermal contrast is hard to be covered, and those who try to camouflage or hide in the bushes or in the dark will have no way to hide.
Thermal imaging technology can detect temperature changes. Infrared thermal imaging camera can produce clear image according to the subtle change of temperature, that is, heat source signal. The image produced by it under any weather condition and without any other light source can be seen clearly, making the object be very delicate. Infrared thermal imaging camera can also detect human shaped targets far away, so it is very suitable for border surveillance.
There are two types of thermal imaging cameras: one is equipped with uncooled micro thermal detector, and the other is equipped with cooled detector. Generally speaking, the latter is more suitable for border defense applications because of its longer shooting distance than the former. Some infrared thermal imaging camera equipped with refrigerated detectors can detect human size targets 18-20 kilometers away.
If conditions permit, infrared thermal imaging camera is usually used with white / low light camera. These are called multi-sensor systems installed on the azimuth / tilt head, and can be easily integrated with the radar system in the STC reconnaissance function. If the radar detects an object, the thermal imaging camera will automatically turn to the correct direction, which is convenient for the operator to see exactly what the light spot on the radar screen is.In addition, the multi-sensor configuration can also be equipped with GPS and digital magnetic compass to ensure that the operator is clear about the position and direction of the camera. Some systems are also equipped with laser rangefinders, which can measure the distance of objects, and can also be optionally equipped with a tracker.
