SAFE WORLD & GREEN EARTH
At Greentel Co., Ltd., we are committed to building a safer society, protected from disasters.
We design, develop, and manufacture advanced video enhancers, stabilizers, and integrated systems essential for disaster prevention, management, and effective surveillance. Our mission is to provide high-quality, easy-to-use solutions that improve safety and security in a rapidly changing world.
Our products enhance blurry images in various environments, crucial for monitoring disaster scenes. Special cameras, like thermal and visible-light cameras, are vital in such situations but have their limitations. Greentel’s technology overcomes these challenges, ensuring clearer, more reliable imagery under even more extreme conditions.
We proudly serve customers in Japan, South Korea, Southeast Asia, Europe, and other regions worldwide. Through our diversified export strategy, we contribute to global safety by providing critical systems for military, disaster prevention, and any environment requiring effective surveillance system.
With strong partnerships with South Korean companies, we also offer cutting-edge thermal solutions for surveillance, fire prevention, fever detection, and thermotherapy, ensuring the highest standards of safety.
At Greentel, we believe that customer satisfaction is paramount. We are dedicated to delivering the best solutions, ensuring a safer, more secure world for everyone.
