Vertex MH-103A4B Three-wire surveillance kit

This surveillance style audio accessory enables more covert communications by allowing the user to remotely control the radio without anyone knowing. The three wire kit features separate wires for receiving transmissions, push-to-talk (PTT) and microphone. The user can discreetly hide the radio, PTT button and speaker so as not to draw attention to radio communication. This can be ideal for private security firms, hospitality, retail and education markets where discreet communications are important.
