There are 3 kinds of audio modes in 2 way audio security cameras: simplex, half-duplex and full-duplex audio transmission.

You can have a full knowledge of the 3 audio transmission modes in the below chart.

Comparison Listing Simplex Half-Duplex Full-Duplex
Direction of Communication/Transition Unidirectional Two-directional, but only one at a time Two directional simultaneously
Send/Receive You can send data but cannot receive. You can both send and receive data but only one at a time. You can send and receive data simultaneously.
Performance Full-duplex audio transmission works better than simplex and half-duplex audio modes, as it doubles the utilization of bandwidth.

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

In 2 way audio IP 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 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 the face-to-face talk.

The advantages of two way communication CCTV surveillance cameras include:

  • You can listen and talk to your kids, your elderly parents, and loved ones anytime you like.
  • You can let a delivery man leave your package in the place you prefer.
  • You can give your pets orders to let your furry friends not rock the boat.
  • You can scare off any potential thieves by the verbal warning.

As you may notice, there are security cameras with audio recording in the market.

Security cameras with audio will record audio while doing video recording. You cannot talk to your children or family with this type of security cameras.

Home IP security cameras with two-way audio, on the other hand, offer you real-time communication as well as audio & video recording.

In the market right now, the majority of traditional PoE bullet and dome security cameras, especially the outdoor type, will not have the two-way audio function.

Those PoE outdoor security cameras are usually installed in high places, such as the eaves. You may not hear the voice clearly since the cameras are installed high above the roof (if the cameras are with bidirectional audio).

If the installation environment is noisy, it’s even more difficult for you to get high-quality two-way communication.

So if you want to find PoE security cameras with two way audio, it would not be the best choice.

For high-quality two-way audio and easy setup, those smart home security cameras with two-way audio, such as baby monitors and battery powered security cameras, would be a better option.
