The one-wire surveillance kit consists of a single wire and earset. This system allows the user to receive transmissions coming from their radio in high noise environments, or commonly used as a surveillance earpiece where normal radio transmissions cannot be heard clearly.

The one-wire kit has standard 2.5mm, 3.5mm and 3.5mm screw thread jacks. Please identify which jack is appropriate for your radio system. If your requirements need a modular surveillance system setup, please review our two-wire and three-wire systems for further options.

Coiled audio tube and open earmolds can be purchased as accessories through our online store. Custom earpieces can also be manufactured upon request. Please contact us for further details.
