Install Nest Cam with Floodlight

The Nest Cam with Floodlight is designed to replace an existing floodlight and requires a connection to your home’s power that provides 100-240V AC, 50/60Hz.  If you want to install the floodlight in an area that doesn’t have an existing power connection and you need a junction box installed, or if you want help installing the floodlight, contact a pro.

What you’ll need for installation

Before you begin, make sure you have the following tools available:

  • Philips screwdriver
  • The hex key that comes with your floodlight
  • Ladder, if necessary
  • A power drill
  • A level

Add your camera to the Home app

To begin, set up your camera with the Home app. When the app asks you which product you are adding, make sure that you select Nest Cam with floodlight.

  • The app has the full instructions you will need to install your floodlight and will walk you through installation step by step.
  • When your floodlight is installed, it will also show you how to set up your camera


  • Make sure you turn off power to your current floodlight at the circuit breaker or fuse box to protect yourself and your system. Try to turn your current floodlight on to make sure the power is off.
  • Take pictures of your current floodlight’s wires to use as a reference later.
  • After you’ve removed your old floodlight, wrap the power wires around a pencil to keep them secure.
  • If you want to paint the mounting plate cover, make sure you use water based paint. Do not paint your camera. Learn more about painting Nest products.
  • After you’ve set up your camera and floodlight, you can adjust the floodlights light settings in the Home app.
  • Important: Nest Cam with Floodlight is designed to be mounted upright on vertical surfaces. Installing it any other way (such as horizontally, sideways, upside down, or at an angle) may reduce the floodlight’s functionality by limiting the motion sensor’s field of view.

Troubleshoot if needed

If you have any issues during setup or testing, here are some quick tips.

You don’t find a grounding wire

Grounding wires are usually copper, green, or green and yellow. If you don’t find a wire, your junction box might have a grounding screw.

  • If you have a grounding wire, connect both wires with a wire nut.
  • If you have a grounding screw, connect the wire to the screw and tighten.

Floodlight doesn’t turn on when you test it

After you’ve installed your floodlight and turned the power back on, your floodlight will turn on for 30 seconds. If it doesn’t turn on, turn off the power to your floodlight and check that your wires are connected and that the wire nuts are screwed on tightly.
