Made in the USA since 1979
The ASK-4® #431 is a two zones audio monitoring system designed ideally for connection to IP cameras or NVRs. When ceiling mounted, the two Verifact® A microphones can pick up sounds within a 30′ diameter circle.

- Line level audio output (RCA jack)
- Adjustable gain potentiometer
- Low-profile for ease of installation
Verifact® A:
- Omni-directional, within 30′ diameter circle
- High impact anti static ABS microphone housing
