RDN-301 Photoelectric detection equipment integrates infrared thermal imaging camera and color camera, it has clear imaging, good concealment, and is not limited by light sources, the imaging is clear and detection distance is long. It has two working modes, day and night. The day mode uses visible light lens for imaging, and the night mode uses thermal imager for imaging, which can realize long-distance continuous observation day and night, and work all the day. The equipment has high-precision turntable, high wind resistance level, high positioning accuracy, stable control, fast response speed, and realize all-round monitoring without blind angle. The shell is made of high-strength aluminum alloy and stainless steel, light and strong, strong wind resistance, high and low temperature resistance, corrosion resistance, waterproof of and acid rain resistance. It can be widely used in nighttime, harsh environment, long-distance, large-scale, concealed real-time monitoring place.
