Reduced or Artificial LightingCoroCAM Low-light Corona Cameras & North American Distributor
Night Vision Scopes These must be evaluated before buying to verify they have high gain 30,000 to 60,000 preferred and have vision into the Ultraviolet. Night vision scopes sensitivity is typically highest in the near infrared and lowest in the ultraviolet.
B E Meyers Night Vision Scopes
ITT Night Vision Scopes, Binoculars Not recommended for this application by the manufacturer.
FJW Optical Inc. -"Find-R-Scope" UV Scope This scope does have limited range dependent upon strong signal strength and only use in complete darkness. Not recommended for this application by the manufacturer.

Radar Engineers - Ultrasonic Instruments
Infrared Cameras ISI Infrared Solutions Inc. Radio / TV Interference Detectors / EMI Trackers:A word of caution, there are many interference sources, and many frequencys of emission. Don't put all your eggs in this basket. Emission sources can be continuous or random (i.e. only on windy days), an arcing source produces broadband emissions. A car radio tuned to a low noise part of the AM band when driving or an inexpensive AM radio is a good detector, the extended antenna is a safety concern but will point (null) at the source.
