UV light can be divided in several categories including UVC or germicidal UV. UVC light works by breaking bonds in a microorganism’s genetic code. This damage can stop the microorganism’s ability to repair and replicate which prevents infections. The ability of UVC light to kill microorganisms is directly related to the power delivered to the microorganisms. This power is determined from the power of the UVC source, the distance from the UVC source to the microorganism, and the time of exposure.
When microorganisms are exposed to UVC light, the energy is absorbed by the microorganism’s genetic material. The photons are absorbed by the microorganism’s DNA/RNA, rendering it no longer infectious. (Harm 1980)
When using the UVCeed application, a three-dimensional representation of the area being treated is made. Then by tracking the time and location that the UVC is active, the application creates a real-time map of the UVC power delivered by the UVC. This allows the user to know they are reaching the desired power levels in the treatment area. UVCeed also leverages machine vision to monitor the treatment area to reduce the risk of accidental exposure and misuse.
The same energy that can kill microorganisms may have an affect on humans as well. UVC exposure is hazardous to the skin and eyes. Overexposure to the skin can cause a sunburn-like reaction, and over exposure to the eyes can cause them to be painful and/or itchy. UVCeed uses machine vision to constantly monitor the area being treated for humans, dogs and cats. If any of these are detected, the UVC energy will automatically be disabled.

*In independent laboratory testing, UVCeed was shown to reduce Staphylococcus aureus by 99.9% in 15 seconds, Escherichia Coli by 99.99% in 24 seconds and SARS CoV2 by 99.9% in 32 seconds. Tested at 12.7 cm on hard non-porous surfaces. In testing at 6.5 cm on hard non-porous surfaces, UVCeed was shown to reduce SARS CoV2 by 99.99% in 64 seconds.
