SYSTEM REQUIREMENTS
To use Nest Detect, first you’ll need to set up Nest Guard and add it to your
Nest Account. You’ll need a compatible iOS or Android phone or tablet with
Bluetooth 4.0, and a Wi-Fi 802.11 a/b/g/n (2.4GHz or 5GHz) network connection.
Go to nest.com/requirements for more
information. Nest Detect must be placed within 50 feet (15 m) of Nest Guard.
Set up Nest Detect with the Nest app
IMPORTANT: Be sure your Nest Guard is already set up and connected to the
internet before you set up Detect.
Meet Nest Detect
Nest Detect can tell you what’s happening in your home. Its sensors detect
when doors and windows open and close, or when someone walks by. When it
notices something, it will let Nest Guard know to sound an alarm. You can also
get an alert sent to your phone, so you’ll know what’s happening when you’re
away.
How Nest Detect works
Nest Detect will sense different things depending on where you place it.
On a door
Nest Detect can sense when a door opens or closes, or when someone walks
nearby.
On a window
Nest Detect can sense when a window opens or closes.
On a wall
Nest Detect can sense when someone walks nearby.
Detects motion in a room or hallway
Detects open-close (Requires open-close magnet) Where you can place Nest
Detect Mounting height Nest Detect must be mounted 5 feet to 6 feet 4 inches
(1.5 to 2 m) above the floor. If you mount it higher or lower, the detection
range decreases, and you may also experience false alarms. Standard detection
area Nest Detect can sense motion from people walking up to 15 feet (4.5 m)
away.
Dog Pass
If you have a dog under 40 pounds (18 kg), turn on Reduced Motion Sensitivity
in the Nest app settings to help avoid false alarms. There are different
installation requirements and motion detection ranges when using Reduced
Motion Sensitivity.
Mounting height
Nest Detect should be mounted exactly 6 feet 4 inches (1.9 m) above the floor.
Reduced Motion Sensitivity detection area
Nest Detect can sense motion from people walking up to 10 feet (3 m) away.
Installation tips
Use the Nest app
During setup, the Nest app will show you where to put Nest Detect and its open
close magnet so they work properly. Here are more things to consider before
you install Nest Detect on a wall, window or door.
Mounting with adhesive strips
Nest Detect and the open-close magnet should be installed on smooth, flat
surfaces only.
- Make sure the surface is clean and dry.
- Peel the protective cover off the adhesive strip.
- Press evenly with your palm and hold in place for at least 30 seconds. The adhesive strips shouldn’t be used on surfaces painted with low-VOC or zero-VOC paint or any surfaces not listed on page 15.
IMPORTANT
Nest Detect’s adhesive strips are very strong and can’t be easily
repositioned. Before you press and hold it for 30 seconds, be sure Nest Detect
is straight and in the right spot. Mounting with screws Install Nest Detect
with screws if your walls, windows or doors have rough surfaces, are contoured
or dirty, are prone to heat or high humidity, or are painted with low-VOC or
zero-VOC paint. For best results use a Phillips #2 screwdriver.
- Remove Nest Detect’s mounting backplate and you’ll see the screw hole.
- Remove all the adhesive material from the backplate.
- Screw the backplate onto the surface. Drill a 3/32″ pilot hole first if you’re attaching it to wood or other hard material.
- Snap the Nest Detect onto its backplate.
To install the open-close magnet
- Snap off the backplate and you’ll see the screw hole.
- Remove all the adhesive material from the backplate.
- Screw the backplate onto the surface.
- Drill a 1/16″ pilot hole first if you’re attaching it to wood or other hard material.
- Snap the open-close magnet onto its backplate.
Installing Nest Detect on a door or window
- Nest Detect should only be installed indoors.
- Install Nest Detect on the upper corner of a door or window with the Nest logo right side up.
- Nest Detect should be attached horizontally on vertical double-hung windows.
- Make sure you choose a spot for Nest Detect where the magnet can also fit. They need to be installed close together to sense when doors and windows open or close.
IMPORTANT
Nest Detect should only be installed indoors. Orienting Nest Detect for
motion detection When installing Nest Detect on a door or wall, the Nest logo
must be upright to detect motion.
Installing the open-close magnet
Install the magnet on the door or window frame inside the room. You’ll know
it’s in the right spot when the Nest Detect light ring turns green.• The
magnet should be aligned with the bottom of Nest Detect and placed within 1.5
inches (3.8 cm) of Detect when the door or window is closed, as shown in the
image to the below.
Installing Nest Detect on a wall
- Choose a flat spot on the wall or in a corner of a room. For more information on mounting heights refer to page 8.
- Make sure Nest Detect is pointed toward the area you want to keep track of. For more information on motion detection range, refer to page 8.
- To install Nest Detect in a corner, take off the flat backplate and use the included corner backplate for installation.
Features
Quiet Open
When the security level is set to Home and Guarding, you can use Quiet Open to
open a door or window without the alarm going off. Press the button on the
Nest Detect that you want to use. The light ring will turn green, and you’ll
have 10 seconds to open it. Your Detect will automatically re-arm when you
close the door or window. You can enable or disable Quiet Open in the Nest
app’s Settings menu. Select Security then Security Levels.
Pathlight
When you walk by Nest Detect in the dark, Pathlight turns on to help light
your way. Using Pathlight may decrease Nest Detect’s battery life, so you can
change the brightness or turn it off with the Nest app. Pathlight is off by
default. You’ll need to turn it on with the Nest app in Nest Detect’s Settings
menu.
Dog Pass
If you have a dog under 40 pounds (18 kg), you can turn on Reduced Motion
Sensitivity with the Nest app to help prevent false alarms caused by your dog.
For more information, see page 9.
Tamper detection
If someone tampers with Nest Detect and removes it from the backplate, the
Nest app will send you an alert to let you know.

Safety and useful information
Special considerations
- In some installations the magnet may need to travel up to 1.97″ (50 mm) for Nest Detect to detect that a door or window is open.
- Don’t install Nest Detect outdoors.
- Don’t install Nest Detect in a garage.
- Don’t install Nest Detect on glass.
- Nest Detect can’t detect motion through glass, like if someone’s moving outside a window.
- Don’t install where Nest Detect could get wet, like swing-out windows that could be rained on.
- Don’t install Nest Detect or the open-close magnet where pets or young children can reach them.
- Don’t expose the adhesive mounting strips to oils, chemicals, refrigerants, soaps, X-rays or sunlight.
- Don’t paint any part of Nest Guard, Detect or Tag.
- Don’t install Nest Detect near magnets other than the open-close magnet. They’ll interfere with Nest Detect’s open-close sensors.
- Don’t install Nest Detect within 3 feet (1 m) of a heat source like an electric heater, heat vent or fireplace or another source that may produce turbulent air.
- Don’t install Nest Detect behind large appliances or furniture that may obstruct its motion sensors.
Maintenance
- Nest Detect should be cleaned once every month. If the motion sensor gets dirty, the detection range could decrease.
- To clean, wipe with a damp cloth. You can use isopropyl alcohol if it gets really dirty.
- Make sure Nest Detect senses motion after cleaning. Follow the testing instructions in the Nest app.
Temperature considerations
Nest Detect is meant to be used indoors in temperatures of 0°C (32°F) to 40°C
(104°F) up to 93% humidity
Battery replacement
The Nest app will notify you when a Detect’s battery gets low. Remove the
battery and replace it with another Energizer CR123 or Panasonic CR123A 3V
lithium battery.
To open the battery compartment
- If Nest Detect is mounted to a surface, grip the topand pull it firmly toward you.
- If Nest Detect is not mounted to a surface, use a flathead screwdriver to pry off the backplate.
Troubleshooting offline issues
If one or more Detects are listed as offline in the Nest app after
installation, they may be too far from Guard to connect. You can install a
Nest Connect (sold separately) to bridge the gap, or try moving your Detects
and Guard closer together.
False alarms
The following may cause unintended alarms:
- Pets that walk, climb or fly above 3 feet (1 m)
- Pets heavier than 40 pounds (18 kg)
- Heat sources like electric heaters, heat vents and fireplaces
- Cold sources like drafty windows, air conditioners and AC vents
- Curtains near windows that may move while Nest Guard is armed
- Direct sun exposure: the front of Nest Guard and Nest Detect should not be placed in direct sunlight
- Party balloons left unattended: they may drift into the field of view of your sensors
- Insects that may come very close to the sensor
- Vibration or movement caused by pets bumping
- Nest Guard when it’s set to Away and Guarding
- Wireless access points within 6 feet (2 m) of Nest Detect.
Wireless communications
- Nest Guard and Nest Detects are engineered to communicate with each other if they’re within 50 ft of each other in a home.
- Some features of a home may reduce the effective range, including the number of floors, number and size of rooms, furniture, large metallic appliances, construction materials, and other features like suspended ceilings, ductwork and metal studs.
- Nest Guard’s and Nest Detect’s specified range is for comparative purposes only and may be reduced when installed in a home.
- Wireless transmissions between buildings will not work and the alarms will not communicate properly.
- Metal objects and metallic wallpaper may interfere with signals from wireless alarms. Test your Nest products first with metal doors opened and closed.
- Nest Guard and Nest Detect have been specifically designed and tested to comply with the standards for which they are Listed. While Nest’s wireless network may route signals through other Nest or other
- Thread-compatible products* to optimize network reliability, you need to ensure every
- Nest Detect can communicate with Nest Guard directly
