Getting started with Nest Secure
Can you show me how it works?
Absolutely. We have some short videos that can give you a good idea of what it’s like to set up and use Nest Secure in your home.
Where can I put Nest Secure and what does it see?
Nest Secure includes one Guard (the brains of the system) and two Detects (small multi-purpose sensors). Both can sense motion.
Guard can sense motion from people walking up to 10 feet (3 m) away.
Detect can sense motion from people walking up to 15 feet (4.5 m) away. If you install it on a door or window, it can sense opening and closing.
When you’re first setting up a Detect, the Nest app on your phone will ask you whether you want to install it on a door, window or wall. It can sense different things depending on where you’re going to install it:
|On a door||On a window||On a wall|

Where you place the Detects is up to you, but you may not need both a Detect and Guard watching the same location. So for instance, you could place a Detect on the back door if Guard is near your front door. Read more tips at the following link:

Are professional installers available?
Yes. We designed Nest Secure to be easy to install yourself, but you could have a pro do it for you.
A pro can take care of installation from start to finish, and even show you how to use your system after it’s set up. Don’t want to install it yourself? Contact our installation partner, OnTech, to help you check your system’s compatibility, install, and set up your Nest products.
Nest Pros are independent contractors who have access to exclusive training and tools for Nest products, so they can help you evaluate the needs of your home and your family and get the most out of your installation.
Note: Nest Pros are a network of independent companies or contractors and are not employed by Nest.

Is Nest Secure UL certified?
Yes, Guard and Detect are UL certified. For more information, see the following article:
Using Nest Secure
How do I arm and disarm Nest Secure?
There are several easy ways to arm and disarm Nest Secure.
Nest Secure has three arming levels.
The table below summarizes what happens for each level:
Use when you don’t want security.
The alarm won’t sound.
Home and Guarding
Use when you’re home and want security.
The alarm sounds when a door or window opens.
Alarm and security alerts
Away and Guarding
Use when no one is home.
The alarm sounds when a door or window opens, or when there’s motion in a room.
Alarm and security alerts

For more information, visit the following article:
Can I arm and disarm with the Nest App?
Yes. Whether you’re home or away, you can open the Nest app and switch your alarm system to Away and Guarding , Home and Guarding , or Off . You can also turn off the alarm if it got triggered accidentally by someone you know.
For more things you can do with the Nest app, visit the following article:
The Nest app can also send you a reminder if Nest Secure isn’t armed after everyone’s left home. Read more about this helpful feature in the article below:

Will my pet set off the alarm?
We made Nest Secure dog friendly. If you have a small
When Reduced Motion Sensitivity is enabled, Nest
If you have a pet other than a small to medium sized dog, you can disable motion detection on some or all of your Detects, and for Guard if needed.
Will my other Nest products help detect intruders?
No, other Nest products currently don’t trigger Nest Secure’s alarm.
Nest uses motion detected by Google Nest Protect and Google Nest Thermostat for Home/Away Assist, but not to trigger Nest Secure’s alarm. Nest Protect and Nest Thermostat detect occupancy, not intrusion. With intrusion we need to be more certain that it is a person in the room to avoid false alarms. Also, devices must be certified for security in order to sound the alarm.
If the Nest camera detects a person, you can receive a Person Alert notification on your phone but the camera will not trigger Nest Secure to sound the alarm.
What other settings can I change?
At Nest, we’ve designed home security for the people who live there. So Nest Secure gives you different ways to set up your alarm system depending on your family’s needs.
Simply open the Nest app on your phone or tablet and choose the settings you want.
Customizing Nest Secure
Can I pick how much time I have before the alarm triggers?
Yes. The Nest app offers a range of options for the alarm countdown. You can even choose one countdown timer for leaving and a different timer for coming home.
Can I set an arming and disarming schedule for a visitor?
Yes. When you invite someone to share access to your home, you can give them Home Entry Only access. This means they’ll only be able to use the Tag or passcode you assign to them, and you can schedule when they’re able to arm and disarm Nest Secure. If someone overstays their welcome and the alarm goes off, they won’t be able to turn it off.
See the following article for details:
Can I turn off motion detection for one or more Detects?
Yes, you can turn off motion detection for any Detect that’s installed on a door if you only want open-close detection. For instance, this can be useful for sliding doors with curtains. Curtains can move and set off the motion sensor, but you still might want to know when the door opens and closes. This option is in the Nest app: Settings Security Select Home and Guarding or Away and Guarding Motion detection Tap the switch next to the Detect to turn motion detection on or off.
Note: If you want the motion detection setting on a Detect to be the same for both Home and Guarding and Away and Guarding, you'll have to go into each security level.
You don’t need to worry about Detects on windows since motion detection is disabled for them.
You can’t turn off motion detection for Detects installed on walls since wall-mounted Detects only look for motion. If your pets are causing a wall-mounted Detect to trigger alarms, a different approach might be to install your Detect somewhere else. Our article about moving Detect to a new location will walk you through the process.
Can I change my passcode?
Yes, and the Nest app makes it easy.
If you’re the Owner of the Nest home or you’re a family member with Full access, you can pick your own passcode or have a random passcode assigned to you.
If you have Home Entry Only access, simply ask the Owner or someone with Full access to change your passcode for you.
The following article explains the breakdown between the Owner, Full access, and Home Entry Only:
For instructions on changing a passcode:
Can I disable a Tag or assign it to someone else?
Yes to both. We made it easy to disable access if something happens to your Tag. Simply disable it in the Nest app. You can even turn it back on again if it eventually turns up.
You can loan someone your Tag for a short time without assigning it to them in the Nest app. But if you do this, the Nest app’s Security History won’t be able to tell you who was using it. So you might want to go ahead and assign the Tag to them.

What does the alarm sound like and how loud is it?
Per UL certification, Guard’s siren is set at 85 dB at 10 feet (3 meters). It is not adjustable to ensure that it’s always loud enough.
In addition, Guard’s light ring will flash red and it will say what triggered the alarm and where. For example, “The window was opened in the master bedroom”. This will repeat for 10 minutes. Visit the following article to learn more:
And, as long as Nest Secure has a Wi-Fi or cellular connection, you can get a notification in the Nest app when the alarm is triggered.

Can Nest Secure detect breaking glass?
Can Nest Secure work during a power outage?
Yes. Guard comes with a backup battery that will keep it powered on for at least 12 hours in case it gets unplugged or your home’s power is out. Nest Secure will still be able to look after your home and sound the alarm if needed, and you’ll still have access to key security features such as arming and disarming with a passcode or a Tag. More details at the following article:
If your home’s power goes out, your Wi-Fi might go down too. Adding professional monitoring with cellular backup can allow your Nest Secure to continue to send you notifications about security events in your home.
Your Detect sensors don’t depend on Wi-Fi to communicate activity to Guard. See the section below for more information.
Can Nest Secure work if Wi-Fi goes down?
Yes. Although Nest Secure uses Wi-Fi for certain things like sending notifications to your phone, it doesn’t rely on Wi-Fi to monitor activity or sound the alarm. The Detects installed throughout your home use a different technology called Weave to communicate with Guard. So, if any of your Detects sense activity, Guard can sound the alarm even without a Wi-Fi connection.
However, without Wi-Fi, you won’t be able to use the Nest app to view and control your alarm system or get notifications. Adding professional monitoring with cellular backup lets your Nest Secure continue sending you notifications about security events. For more information, including a chart showing which Nest Secure features are available with and without Wi-Fi, visit the following article:
Does Nest charge a monthly fee to use Nest Secure?
No. Your starter pack comes with Guard, two Detects and two Tags. You’ll also need a working Wi-Fi internet connection in your home, and you’ll need to install the free Nest app on your phone or tablet. After you set up and install your alarm system there’s no additional monthly fee to use it.
An optional professional monitoring with cellular backup subscription is available for Nest Secure. This subscription is not required to use your Nest Secure alarm system and it's up to you to decide if it is right for you and your home.
What comes included with Nest Secure
All the features listed in the Welcome Guide except professional monitoring and cellular backup come included with your Nest Secure at no additional charge. Your starter pack comes with two Detects, one Guard (also a motion sensor), and two Tags. Along with your home Wi-Fi and the Nest app on your phone or tablet, this is everything you need to use your alarm system. If you decide you want more coverage around your home, you can add additional Detects as needed.
Here are a few key features that come included:
- Arm and disarm in three ways (Guard, Tag, and the Nest app).
- Control your system remotely with the Nest app. Change settings, set the alarm, and receive notifications if there’s been a security event.
- Set Remind Me alerts to remind you to set the alarm when everyone’s gone.
- Automatically use battery backup when the power goes out.
Optional services not included
- Professional monitoring: If Nest Secure sends a notification to your phone, you’ll need to respond to it yourself. 24/7 professional monitoring is an extra layer of security, provided by our professional monitoring partner Brinks Home Security, that links you up with trained experts to help you through an emergency. Professional monitoring comes with Cellular Backup, see details below.
- Cellular Backup: Cellular backup will kick in if your home Wi-Fi goes down. Your Guard and Detects don’t rely on Wi-Fi to talk to each other, but Guard needs Wi-Fi to send notifications to your phone. With cellular backup your Guard can send notifications without Wi-Fi. For more details, see the next question.
That’s it! All of Nest Secure’s other features are included when you purchase your starter kit.
What is cellular backup and how does it work?
Normally, Guard uses Wi-Fi to connect to the internet so you can get alerts and manage security settings on your phone no matter where you are.
If your home’s power is out or your Wi-Fi goes down, a cellular backup subscription can help to make Guard and Detect even more reliable.

If you subscribe to professional monitoring (see below), a cellular backup subscription is included.
What is professional monitoring and how does it work?
