DayCor® micROM HD is an innovative corona camera designed for use on UAV. It is electromagnetically shielded, small and light with ready interfaces to communication protocols. micROM HD is the first micro HD camera with dual sensors UV & Visible, capable of detecting and imaging corona in daylight.  micROM HD is offered with or without Plug-N-Play integration solution (see accessories).

micROM HD streams out videos of the inspected electrical elements revealing sources of corona and records them internally. With the embedded DayCor® technology micROM HD acts as a high sensitivity testing equipment providing reliable precise information about electrical and mechanical faults. micROM accepts external GPS and ambient condition data and integrates them with the recorded footage.

micROM HD comes with ready to use ports for communicating with drones. Integration is easy and straight forwards. micROM is remotely controlled by a set commands that are supplied to drone operators to be configured on their remote control.  The HD imaging serves well the need for detailed clear views of remote specific grid elements.

micROM HD is offered both as a block camera that fits well into a wide range of gimbals and as OEM camera core per individual preferences and optional customization.

Corona Discharge Camera - Practical, Powerful, Precise, Affordable


In order to maximize flexibility, duration and velocity weight must be kept at minimum. micROM HD is a lightweight camera with energy-efficient management allowing longer, higher and faster flights while scanning power lines. micROM HD silhouette simplifies the outline of gimbal design requirements.


micROM HD streams & records HD videos providing clear views of the inspected scenes, allowing reading plate names & catalogue numbers of equipment for maintenance referencing. Videos can include corona events count, date & time, GPS, temperature and humidity (optional). High resolution guarantees more observed detailed data.


micROM HD provides in real time the representation of corona as it is emitted, displaying both the discharges and the faults. Imagery is clear and sharp even while on the move. Output is used to determine faults’ location and level of severity.

Above and Beyond Traditional Inspection

“As of Aug 2019, SDG&E is the first company in the United States to fly the corona camera on the UAS with the support of a local vendor integrating the camera on a UAS. In recent work, SDG&E completed 5 successful test flights on August 19- 20, 2019 and again on September 12, 2019 and assessed twelve 230kV tower structures, which took approximately one and half hours to complete. The normal way for this inspection is to use a handheld corona camera and that would have taken four hours. More testing is scheduled for 2020, and efforts will be made to integrate the procedures into the regular workforce operations.
