#2. What Is a Two-Way Audio IP 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.

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

You can have 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 it. 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 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 with the two way audio over IP.

The advantages of CCTV with two-way audio 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 pet 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 only record audio while doing video recording. You cannot talk to your children or family with this type of security camera.

2-way audio video security cameras, 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.

The PIR motion detection two-way audio surveillance cameras detect changes in the amount of infrared radiation impinging upon the PIR motion sensor, which varies depending on the temperature of the moving objects.
