As you will see it is possible to even use the two-way audio feature from your smartphone using our iOS and Android Apps. We are using a laptop's speakers as the audio out. By using an audio amplifier, it is possible to use a PA speaker and connect it to the RCA audio output of one of our DVRs.īelow is a quick video that demonstrates this two-way talk feature on one of our DVRs. To talk back to the person you would connect your own speaker to the RCA audio output on the back of the DVR. By using add-on security camera mics or security cameras with built-in microphone, you can hear audio from the person in front of the camera. This feature is meant for users looking to setup two-way audio or bidirectional talk in their security camera system. Almost all of our DVRs offer the ability to add a speaker using the RCA audio-out.
