Unlike the AOP530, the AOP540 does not include a push button

The AOP540 is an handsfree analog two-way speaker microphone with Echo cancellation and full-duplex technology allows for two-way communication with excellent quality of sound. It contains a built-in microphone and a 2” speaker for accomplishing bi-directional audio. The AOP540 is easy to install connecting directly to IP cameras and encoders that feature two-way, line level audio. It can be used for indoor or outdoor due to its vandal resistant housing.
