"Green Tel provides two representative image improvers (HVH-200, SV-200) and one image shake corrector (SST-100).

The HVH-200 product is a FULL HD-class surveillance camera (CCTV, thermal imaging camera, etc.) that can significantly improve the image blur due to fog, sand, rain, low illumination, etc. It can be easily installed and used between the camera (or video server) and the display through the HDMI interface.

The SV-200 product is a device that significantly improves the image blur caused by the SD-level surveillance camera (CCTV, thermal imaging camera, etc.) due to fog, sand, rain, low illumination, etc. This is the BNC interface.

The ST-100 product is an SD-level surveillance camera (CCTV, thermal imaging camera, etc.) that can make clear corrections when the image shakes due to strong wind, earthquakes, and vibrations from moving objects. This is the BNC interface. "
