The CoroCAM 504 (released in 2004) is a corona camera used along the entire electric power chain, in day or night.
It is the most sensitive UV camera on the market when used in NV mode.

The CoroCAM 504 brought a couple of world firsts to the UV camera market, i.e.

  • UV blob translucency/shading
  • A removable solar blind filter, it is a motorised function
  • Field upgradeable firmware
  • Light weight camcorder style camera
  • Viewfinder for high brightness environments
  • Auto or manual focus of visible channel
  • UV channel can be synchronised with visible focus or manually focused
  • Industry standard sensitivity to UVc light.
  • UV events counter – not radiometric
  • UV blob convolution filtering for noise reduction
  • UV blob color selection & 50% translucency option
  • UV blob overlay on 0.5x, 1x and 2x zoom levels
  • Stepped zoom is fast
  • UV overlay shows the precise location of the discharge
  • Image capturing, audio clip recording and playback of both
  • Video output for external recording or viewing
  • Cabled remote control
  • Built-in GPS and Laser Pointer (Optional)
