How are the buildings and pavent affected by climate?
Hi. Capture as in record? Sensors have been developed which are sensitive to UV. Capture as in block (like sunscreen)? Chemicals have been developed which break down under UV radiation and absorb the energy by doing so.
Call the fire department (on thier business line) and ask them what to do. Do not ignore a smoke detector unless you know for certian what caused it to go off.
They are powered by 110 volt just like a lamp. DO NOT mess with the wires.
