Norcon's patent pending TTU-1AV Talk-Thru Video Intercom is a 2-way, hands free audio system with a Video Camera that provides high-quality personal communication between people separated by security or isolation barriers that also enables you to monitor or record audio and video. The TTU-1AV is ideal for remote monitoring of ticket booth activities; to allow absentee management; as an additional security camera; and to keep a record of proper customer service.

How it Works
Norcon's TTU-1AV Talk-Thru Communicator provides hands-free communication between people separated by security or isolation barriers.

The TTU-1AV provides clear communication and color video even in environments with high ambient noise through the use of compression circuitry which help to reduce loud, annoying sounds.

Unwanted background noise is minimized through the use of automatic volume attenuation circuitry. If the gooseneck microphone is not used for 30 seconds, the outside channel volume will be reduced approximately 70%. Normal operation is restored as soon as the attendant speaks into the gooseneck microphone.


  • Clear, 2-way hands-free voice communication and color video
  • Rugged, tamper-resistant materials
  • Simple, one-person installation
  • Headset jack permits telephone style headset or wireless microphone
  • Units available for ADA applications
  • Optional bullet-resistance (shield rated up to .44 Magnum service loads--higher level bullet resistant shields available)
  • Optional removable gooseneck microphone
  • Export models available with 220VAC
  • One year warranty on base unit (optional two years extended warranty available)

Installation of the TTU-1AV is a simple, one-person operation. All that's needed is a 3-4 inch cutout in the barrier. Four fasteners and two rubber gaskets for mounting are supplied with the unit.

The fasteners are used to mount the front face and housing on opposite sides of the barrier. The electronic section is then inserted into the housing and fastened in place. The rubber gaskets prevent slippage and protect the barrier surface. Please specify barrier thickness when ordering.

All Talk-Thru systems are shipped complete with mounting hardware, instructions, and power supply.
