ASK-4® #302

LE-374
Summary

The ASK-4® #302 is a two zone audio monitoring system designed ideally for connection to IP cameras or NVRs. When ceiling mounted, Verifact® A microphones can pick up sounds within a 30′ diameter circle. The model IF-2 interface adapter connects to the microphones, supplies power to the microphones and drives audio into the input of the recording device. The two Verifact® A microphones are designed for ceiling mount applications.

IF-2:

  • Line level audio output (RCA) to NVR, IP Camera, etc.
  • Adjustable gain potentiometer
  • Low-profile for ease of installation

Verifact® A:

  • Omni-directional, within 30′ diameter circle
  • Durable, high impact ABS housing
  • Can be placed up to 1000′ away from the base station
