What is Two-Way Audio Security Camera?

Wired cameras or WiFi security cameras with two-way audio (also known as 2-way intercom cameras) typically have built-in microphones and speakers so that you can listen and talk to your family in real-time. So you don't need to purchase the external microphone or speaker to enable the 2-way audio function.

Home security cameras with two-way audio use either half-duplex or full-duplex audio transmission mode.

In Two-way audio security cameras with half-duplex mode, audio is sent in both directions. However, only one party can send or receive audio data at a time, which is similar to a walkie-talkie.

In two-way audio cameras with full-duplex mode, both parties can send and receive audio data through two-way audio IP security cameras at the same time.

In other words, you can chat with your family or children, similar to face-to-face talk with two-way audio over IP.
