Why Powder Watts Patented Technology? Taking proven smart camera computer vision technology to monitor and control heat cables on roofs during Winter. With vision, we know. Stop unnecessary and costly guesswork with Heat Cables. Patented smart camera monitoring of unnecessary heat cable usage. Why: Heat cables cost a lot to run – both in money and environmental impact.
