Wren Thermal
Night flights for hot joints and failing arresters.
Wren Thermal swaps the zoom camera for a high-resolution radiometric core and flies at night, when the sun can't fake a hotspot. It finds joints, clamps and arresters running hot under load.

Overview
Night flights for hot joints and failing arresters.
Heat, measured
Every pixel carries a temperature, so a hotspot becomes a number your engineers can trend: 71.4 °C this month, 64 °C last month, 46 degrees above its neighbours.
Night by design
Flying after dark removes solar gain from steel and glass. What stays hot is heat the line is making, which is what you want to find.
