Why Is My Nest Camera Blinking Blue?

The Nest camera is a part of Google’s variety of home security products. 

While the Nest cam is a great way to monitor your property and boost your sense of security, it’s possible that you’ve had some issues while using it. 

One concern that many homeowners experience is a blinking light. It’s important to note that while a blinking light can be alarming, the problem is usually a simple fix. 

In fact, there may not even be a problem with your Nest camera at all. 

Why Is My Nest Camera Blinking Blue?

A blinking blue light on your Nest camera can be an indication of a completed firmware update. It may also be blinking blue after restarting because it lost power for some reason. The most likely reason you are seeing a light that is blue though is that your Nest doorbell is booting up or restarting.

If you own a Nest camera, read on to learn why your camera may be blinking blue along with answers to a few other FAQs to help you understand the functionalities of your Nest cam better. 

What Do the Light Colors Mean on Nest Camera?

Nest cameras are equipped with a variety of different light colors to communicate with users. 

Assuming that your Nest cam is already set up and ready to go, I’m going to share some common lights you may see while your Nest camera is in use.

Solid Green

A solid green status light on your Nest camera is what you’ll want to see on your Nest camera. 

In fact, solid green means that everything is working normally. 

Green indicates that your Nest cam is turned on, connected to Wi-Fi, and is successfully processing images in its view. 

When the Nest cam is solid green, your camera may be actively recording activity that’s happening around the area and then saving it to the cloud. 

It could also be using local storage to record and save videos when it’s in offline mode.

Pulsing Green

A pulsing green light still means that your Nest cam is working properly, but a live camera action is being used. 

This means that someone may be watching your camera’s video live stream, is using Talk and Listen, or performing a quick action.


A yellow light means that your Nest camera needs attention. 

Generally, a yellow light indicates that the power adapter plugged into your camera has an incorrect wattage. 

If your light is blinking yellow, it could be due to you having the wrong power adapter. 

In fact, some third-party power adapters are not compatible with Nest Cameras.

For reference, Nest cameras require a 7.5 W USB-A power cable to remain powered and working optimally. 

No Status Light

Sometimes, Nest cameras have no status light at all. 

This can be due to the following:

  • Your Nest camera is currently idle and not detecting any activity in the area
  • Your camera is turned off due to a manual shutoff, scheduled shut off, or your Nest is set to Home 
  • Your camera is not receiving power
  • Your Nest camera failed to update its software

How do You Know if Someone is Watching Your Nest Cam?

The different lights offered by the Nest camera can help users understand everything that’s going on. 

With that said, if you’re wondering whether someone is watching your nest camera, look out for a green light. 

A status light that is blinking green means that someone is watching the camera. 

How do I reconnect my Nest Camera to Wi Fi?

Occasionally, your Nest camera may disconnect from your home’s Wi-Fi. 

Without being connected to a Wi-Fi network, your camera won’t actually be able to work. 

Luckily, reconnecting your Wi-Fi is simple. I’m going to show you what you can do to get your Nest camera back up and running again. 

But first, here is some important information to consider before you do so. 

It’s important to note that if you’ve changed your router settings, Wi-Fi password, or installed a new router, you will need to update this information on your Nest Connect, or else it won’t be able to connect to the Wi-Fi. 

If this information has been updated or you haven’t made any changes, you should be able to proceed forward with reconnecting your Nest camera. Here is what to do: 

  • Bring your phone or tablet to the same room as your Next camera. In order to connect successfully, it will need to within range.
  • Go to the Nest app home screen and select “Settings”.
  • Select “Nest Connect”. Be sure to scroll to the bottom if you don’t see it.
  • Tap the Connect for the settings you want to change. 
  • Select “Wi-Fi Connection” and then select “start”. 

If this doesn’t work, another option you can try is to update your settings. You can do a quick update by doing the following:

  • Select the “Settings” on the Nest app home screen. 
  • Then, select “Home Info” and then proceed to “Home Wi-Fi Help”. 
  • Select the camera you want to update. 
  • Tap start to update settings

The Nest camera is an innovative tool made by Google. But just as with any technology, the Nest camera can be difficult for some users to understand. 

While seeing a blinking blue light can be alarming, this doesn’t mean that your Nest camera is malfunctioning. 

A blinking blue light most likely means that the Nest camera is either updating its firmware, the camera has just turned on after a power cut, your Nest is waiting to add a user or it’s restarting, or your camera is restarting.
