Installing Nest Security Pack


Before you mount/place your devices

  1. Register for your T-Mobile ID. You'll need to log into My T-Mobile and get your Nest Security Pack phone number.
  2. Download and install the Nest app.
  3. Create a Nest account or sign into your existing one.
  4. Add your devices in the Nest app. Start with Nest Guard, followed by the Nest Detects or Tags, then the Nest Cam Indoor should be added last.
  5. Follow the on-screen steps to finish setting up your devices, like choosing which camera you're using.
  6. Within 48 hours, Nest will send an email to confirm that your Cellular Backup and Nest Aware service is active.


Nest Guard

  1. Find a good place to put your Nest Guard.
    • You'll want a place with good Wi-fi signal.
    • It should be placed on a flat surface 28-42 inches above the floor within 2 feet of the edge.
    • The motion sensor should face front.
  2. Plug in the Nest Guard.


Nest Detect

  1. You can place a Nest Detect on a door, on a window, or on a wall
    • Doors will detect motion in the room or open/close
    • Window only detects open/close
    • Wall only detects motion in the room
  2. It must be mounted between 5 feet and 6 feet 4 inches above the floor. Higher or lower decreases detection range and causes more false alarms
  3. It can sense motion in the room up to 15 feet away
  4. Check out the user guide for additional installation details.


Nest Cam Indoor

  1. Plug in the Nest Cam Indoor. You'll want a place with good Wi-Fi signal.
  2. Mount your camera. Check out the user guide for additional details. There are several ways to mount:
    • Place it on a flat horizontal surface
    • Attach it to a metal surface with the built-in magnet
    • Attach to a wall or ceiling with the included mounting plate


Set up replacement device

If you receive a replacement Nest device, you'll need to deactivate your previous device before you can install the new one. This does not cancel service with T-Mobile.


  1. Remove your existing device from the Nest app.
  2. Add your replacement device in the Nest app.
  3. If you replaced your Nest Guard, contact T-Mobile to cancel your existing Nest subscription code and activate a new one.
