Having proper illumination around your home is essential. It makes everything look more appealing, especially at night. A Eufy Floodlight camera provides this essential lighting and incorporates a security camera to help you identify unexpected intruders. Eufy Floodlights use a motion sensor, which only turns the lights on when necessary. However, if your lights are not responding to motion, you may be wondering how you can fix it. 

There are several reasons why your Eufy Floodlight camera lights may not be turning on when they should. The automated lights might not be properly set up, you may not be using the appropriate mode for current conditions, or the sensor could be dusty.

Even if the camera is working properly, having lights that don’t switch on in response to motion is frustrating. After all, that is why you bought a floodlight camera! Below, we will investigate all the possible reasons why this might be happening and how to address them. Keep reading to learn more!

Why Are My Eufy Floodlight Camera Lights Not Turning On?

Motion-activated lights are a great way to guarantee you will have light only when you need it to avoid wasting energy unnecessarily. Whether you want to easily see your walkway when you get home late at night, enjoy the tranquility of your backyard after dusk, or catch an intruder red-handed, you need the lights to work consistently.

However, you have found yourself in a situation where the lights are not turning on, no matter how close you are to the camera. The most common reasons behind this problem are:

  • The motion sensor is not turned on
  • An incorrect activation mode
  • A dusty sensor

The reason your lights are not turning on could be due to one or a combination of the issues listed above. Let’s take a deeper look at each of them. 

Turn the Motion Sensor On

Eufy Floodlight cameras have a built-in motion sensor that tells the camera to turn the lights on when it detects motion nearby. If your lights are not turning on automatically when you walk in front of them, it may be because the motion sensor was turned off accidentally or never activated in the first place. 

You can easily change this setting from the eufySecurity app on your smartphone or tablet. Download and install the app on your device, then follow these instructions:

  • Go to “Camera Settings.”
  • Search for and tap on “Light Settings.”
  • Select “Enable Floodlights.”
  • Find “Motion-Activated Light” and change the settings to “Turn on the Motion-Activated Illumination.”

If this setting was not turned on, this step might be all you need to fix your problem. If it was already turned on or changing the setting still does not allow the lights to work properly, you will need to move on to the next step.

Change the Activation Mode

For some Eufy Floodlight models, like the Eufy Floodlight Cam 2 Pro, the issue might have to do with AI recognition. These models will only turn the lights on if a human is detected to avoid activation whenever your dog walks around the backyard or a cat wanders around your property. 

However, when it is dark outside, the human AI recognition system will not be able to “see” as far and might take longer to recognize a person. There is a settings option that may help alleviate this problem. From the eufySecurity app on your phone or tablet, follow these steps:

  • Go to “Camera Settings.”
  • Find and tap on “Light Settings.”
  • Select “Enable Floodlights.”
  • Find “Motion-Activated Light.”
  • Select “Turn on the Motion-Activated Illumination.”
  • Choose “Light Activation Mode,” then change the mode to “Fast Mode.”

This option will reduce the “thinking” time the camera takes to turn on the lights, and you might not lose as much range at night.

Clean the Motion Sensor

Over time, dust and other debris can build up and collect on the sensor. If you have had your camera for quite some time now, this dust may be blocking the sensor’s abilities. This is even more likely if you live in an area with a lot of dust and pollen or if there was a recent dust or rain storm.

To clean the sensor, grab a clean, soft cloth and gently wipe it off. Make sure the cloth will not scratch the plastic surface of the sensor or the glass on the camera, as this could worsen the problem.


If your Eufy Floodlight camera lights are not turning on in response to motion, the best course of action is to check your camera’s settings in the eufySecurity app and clean off your motion sensor with a soft, clean cloth. To ensure the best performance of your motion-activated lights, make sure to turn the motion sensor feature on, activate fast AI human recognition, and keep the sensor clean.
