Vehicle Mounted Inspection System

Models: UV | MS

DayCor® Ranger HD is a vehicle-mounted inspection solution for HV power lines. RangerHD benefits from the unique capabilities of DayCor® technology, implementation incorporating UV-HD camera, in combination with a high-quality IR-HD sensor camera, both mounted on a durable, stabilized, full featured, high-speed pan & tilt positioner.

DayCor® Ranger HD is uniquely matched and customized for each customer with tailor-made configurations, fitting the unique architecture and conditions of the hosting environment. The entire solution aims at providing a comprehensive inspection capabilities for integrated data collection, data management and decision support.

Ranger HD is a very reliable scanning system that provides pinpointed display of corona and its emitting sources and hotspots. The system is designed to be controlled and operated remotely from the vehicle cabin. The control unit installed inside the vehicle includes a joystick (controlling of the pan & tilt unit), camera control (for both the UV and IR cameras), a display unit (presenting both UV and IR video streaming), and a DVR unit (recording videos streamed from the cameras).

The Ranger HD system features include:

  • Outstanding Corona detection sensitivity
  • Supreme IR inspection capabilities (optional)
  • Consolidated control for multiple sensors
  • Easy-to-use control of the mounted cameras features (zoom, focus, etc.)
  • Video recording (including audio and metadata)

Practical, Powerful, Precise, Affordable


DayCor® Ranger HD is a premium inspection solution for driven practices with a selection of optical sensors in a stabilized pan-tilt-zoom mount. Ranger is instrumental to scan extended long overhead lines with right of way. The system supports preset profiles configuration to accelerate response time to the fast-changing scenes. High sensitivity and on-the-fly real-time imaging, that does not involve processing, ensure reliable comprehensive results.


Freezing or sizzling outside, stay in your airconditioned truck and let the DayCor® Ranger provide. Turn on the system and start inspecting. If there is corona DayCor® will catch it for you, stream it to your monitor and store it onto the memory card. The hi-resolution recorded video clips will help you prognose the inspected grid elements and help you generate the expected summarizing reports.


It is all about partial discharge. All it takes is a local distortion of the electrical field that stresses the air and triggers PD, hence there is a limit to what air can endure. Unless you are a Reindeer or a bee, only with a DayCor® you will be able to see. Corona is UV and DayCor® is a UV technology. DayCor® Ranger is a camera system that leads inspectors to the locally discharged corona revealing thereby electrical, architectural and mechanical faults. Never say there is no corona, simply because corona is there but it must be discovered.


Effectively Identify Contaminated Insulators

“.. SDG&E purchased a daytime corona camera to improve patrol reliability. The corona camera also effectively identifies insulator contamination caused by salt deposits. The thermographer combines the corona camera with the infrared camera on the pan/tilt head on the roof of the van. By using this corona technology, inspectors are able to identify areas of concern and investigate the components to determine if their life expectancy has been compromised. To further identify components compromised by corona, SDG&E invested in a gimbal that has a corona camera and mounted it on the helicopter..”
