Recently, I invested in the Arlo security ecosystem and noticed that one of my Arlo cameras was flashing a blue light using its status indication LEDs.
I was perplexed at what this meant, and having discarded the user manual like a normal person, I skimmed through the internet to find a possible explanation.
I found plenty of threads and forum posts with similar queries from a lot of folks.
This got me to write this one-stop article on what the Arlo camera flashing blue actually means and what you can do to fix this.
Here's a brief account of why Arlo Cam flashes Blue light:
Scenarios | Causes and Fix |
---|---|
Solid Blue light | Camera is powered ON and connected to a network; not an issue |
Slow Blinking Blue Light | Pairing with a network or the Base Station underway; move the Cam closer to the Base Station or the Router if persistent |
Fast Blinking Blue light | Arlo Cam successfully paired to a Base station or a network; Not an issue |
Arlo Cam synced to Base Station/network but still flashes Blue | Issue with the pairing/software error; common fixers include refreshing the sync procedure and checking for network issues |

Arlo Camera Blinking Blue but Not Syncing? How to Fix

If your Arlo camera blinking blue signifies that it is syncing or successfully synced according to your model, but actually hasn't been syncing then it is a cause for concern.
This is quite a common issue in fact, with a lot of popular security camera systems, such as Blink cameras not connecting to WiFi and Wyze cameras stuck on 'Ready to Connect'.
Fortunately, this issue can be easily fixed by using some common troubleshooting steps applicable to most security cameras:
Check Your Arlo Smarthub or Base Station
If your Arlo SmartHub or Arlo Base Station is not working properly then your Arlo camera simply will not sync.
This step is important to consider, especially if your Arlo camera is required to be connected to the Arlo Base Station or Arlo SmartHub.
Make sure the connections are proper with the Arlo Base Station or SmartHub.
Do a power cycle on the device to ensure that it is working as intended. You can do the same by following the steps given below:
- Unplug the Arlo Base Station or SmartHub from its power source.
- Let the device sit idle powered off for about a minute.
- Plug the Arlo Base Station or SmartHub back into its power source.
- Let the device sit idle powered off for about a minute.
Check Your Internet Connection
Make sure that your internet connection is active and everything works fine.
If your internet router is far away from the Arlo camera or its Base Station, then try bringing it closer to each other for better connectivity.
Power cycle your internet router multiple times to ensure that the router is working as intended.
If you are facing internet connectivity issues, it is best to contact your Internet Service Provider (ISP) for fixing the connection.
Final Thoughts

If the above troubleshooting steps failed to generate any meaningful result for you, then it is best to contact Arlo support.
If there are any defects in your Arlo camera, Base Station, or SmartHub unit that are hindering the synchronization process, they can help you get it fixed or replaced.
I hope my article on what your Arlo camera is trying to tell you by flashing blue using its status indicators has been a helpful read and has aided you with the same.
Have a good day!
