NAPCO commissioned independent testing (by NY Testing Laboratories, Inc.) comparing Gemini crystal-control wireless transmitters against ITI Concord, Ademco Vista, and DSC Power window/door transmitters in a tough industrial warehouse environment with metal and motors present. NAPCO's GEM-TRANS2 outperformed the competition by as much as 50%, delivering usable signal strength out to 800 feet versus roughly 400β500 feet for the competitors tested.
