What You'll Learn
Nest Cam sound detection and alerts
Nest Cams have sound detection and activation features. The Nest Cam's microphone allows for two-way voice communication, enabling users to speak to whoever is on the other end through the Nest app. The device also has sound detection features that can be enabled through the app. Users can choose to receive notifications for specific types of sounds, such as a person talking, a dog barking, or other sounds.
The Nest Cam uses advanced algorithms to improve sound detection and send more helpful alerts. It measures ambient audio levels, filters out regular noise, and detects fluctuations in noise to identify important audio events, such as a loud crash or the sound of a window breaking. Users can also set up Activity Zones, marking specific areas within the camera's range to receive alerts for.
Nest Aware subscriptions further enhance the sound detection capabilities of Nest Cams. With Nest Aware, the camera can distinguish between different types of sounds, such as a dog bark, a smoke alarm, or a carbon monoxide alarm. It can also detect and recognize familiar faces, sending more relevant alerts over time.
The sound activation features of Nest Cams can be customized to suit user preferences. Users can enable or disable sound detection and notifications through the app, and even disable the microphone if desired. While the Nest Cam offers sound activation capabilities, it lacks advanced sound activation and filtering features, resulting in the capture of all sounds in the monitored area, including background noise.
Overall, the Nest Cam's sound detection and alerts provide users with the ability to monitor and receive notifications for specific types of sounds, enhancing the device's functionality as a surveillance and security tool.

Two-way audio communication
Nest Cams have a microphone feature that enables two-way audio communication. This means that you can talk to whoever is on the other end of the camera by speaking into your smartphone through the Nest app. The person near the Nest Cam will be able to hear you and can communicate back.
The Nest Cam IQ model has full-duplex two-way audio. This means that it comes with a microphone array that can be used to both receive and send audio simultaneously. On the other hand, older Nest Cam models that use the Nest app have a single speaker installed, which means that the audio can only be transmitted or received one way at a time. Therefore, if you are using an older model, you will need to take turns talking and listening. To indicate that you are done speaking and that the other person can begin, the camera will chime.
If you have a Nest doorbell, you can also use the Talk and Listen feature on a Google display like the Nest Hub Max. To do this, make sure that your doorbell and display have been added to the same home in the app. Open the Home app and touch and hold your device's tile. Tap the microphone to turn on the camera, which will chime to indicate that the person in front of the camera can begin speaking. When you are done speaking, tap the microphone again to hang up, and the camera will chime for a second time to indicate that the conversation has ended.
It is important to note that if you disable the microphone on your Nest Cam, you will no longer be able to use the two-way audio communication feature.

Sound activation and noise cancellation
The Nest Cam has sound activation capabilities, as well as noise cancellation features. The microphone on the Nest Cam enables two-way voice communication, allowing users to communicate with whoever is on the other end through the Nest app. This feature can be useful for monitoring babies, as it offers two-way talk functionality with better sound quality than some competitors.
While the Nest Cam does have sound activation, it does not have advanced sound filtering capabilities. This means that if you are monitoring a room, you will hear all sounds, including background noise. Nest Aware algorithms measure ambient audio levels and can filter out regular noise to some extent, such as the sound of a running air conditioner. However, the Nest Cam's sound detection can be upgraded to be more sensitive, picking up on normal conversations as activity events.
The Nest Cam can also detect and distinguish between specific types of sounds, such as a dog bark or a smoke alarm, and send alerts to your phone, tablet, or email. This advanced sound and motion detection feature requires a Nest Aware subscription and significant computing power. The subscription also allows for more refined activity detection over time as updates are made to the cloud servers.
To disable sound on the Nest Cam, users can open the Nest app, access the camera's live view, and turn off the microphone in the settings. Disabling the microphone will result in the Nest Cam no longer picking up any sound, and all recordings will be without audio.
Now, moving on to sound activation and noise cancellation in general, these are commonly referred to as active noise control (ANC) and noise cancellation (NC), or active noise reduction (ANR). The concept involves reducing unwanted sound by introducing a second sound designed to cancel out the first. This is achieved through analog circuits or digital signal processing, utilizing adaptive algorithms to analyze and generate signals that interfere with and effectively reduce the volume of the original sound.
Commercial applications of active noise control include noise-canceling headphones and earbuds, anti-snoring devices, and the reduction of engine noise in vehicles. Modern mobile phones also employ multi-microphone designs to cancel out ambient noise and improve voice sound quality. Additionally, certain devices like the Samsung Galaxy Buds and Apple AirPods offer Active Noise Cancellation and Transparency modes, allowing users to adjust how much of their surroundings they want to hear.

Nest Aware subscription and sound detection
Nest Cam does have sound activation and detection features. The microphone on the Nest Cam enables two-way voice communication, allowing users to speak to whoever is on the other end through the Nest app. The Nest Cam's sound detection feature can also be used to notify users of specific sounds, such as a dog barking or a smoke alarm.
The advanced sound detection features of Nest Cam require a Nest Aware subscription. Nest Aware is a video recording subscription service for Nest Cams, with two tiers of pricing: Nest Aware and Nest Aware Plus. Nest Aware Plus offers extended video history and costs $20 per month or $200 per year. With a Nest Aware subscription, Nest cameras use advanced algorithms to pick out different kinds of activity and send more helpful alerts to the user's phone, tablet, or email. The Nest Aware algorithms measure ambient audio levels and filter out regular noise, allowing the camera to detect fluctuations in noise and identify important audio events, such as a loud noise or the sound of breaking glass.
To set up sound detection with a Nest Aware subscription, users need to open the Google Home app and enable the microphone for their speaker or display. They can then select which speakers and displays will participate in sound detection and choose which sounds can be detected. It is important to note that sound detection settings apply to all home members, although each member can set their own notification preferences.
The sound detection feature on Nest Aware is currently only available in the United States. Additionally, smoke and carbon monoxide alarm detection, as well as glass-breaking detection, are not available with a first-generation Nest Aware subscription.
