Case Study: Smart Substation Monitoring (USA)

“We deployed the substation inspection 4k zoom lens in our AI-enabled monitoring cabinets. The lens’ ir corrected zoom lens 850nm 940nm option provided consistent focus under both visible and NIR lighting. Engineers now use it to track insulator degradation and overheating spots without deploying handheld scopes. Its 8–32mm c-mount motorized zoom and programmable I²C control allow our system to capture both wide context views and detailed close-ups automatically.”
