Samsung Camera Not Detecting Motion? Here's the Fix

Your Samsung security camera's primary job is to alert you to unexpected activity. If it fails to detect or notify you about motion, it's not providing the security you need. You might find that people can walk past the camera without triggering a recording, or you might see an event happen on the live view but receive no corresponding alert on your phone.

This problem is almost always caused by a misconfiguration in the software, either in the SmartThings app or in your phone's notification settings. Physical obstructions can also play a role. This guide will walk you through the essential checks to get your motion detection and alerts working correctly.

Common Reasons for Motion Detection Failure

Before you start troubleshooting, it helps to understand what might be going wrong. The issue typically falls into one of these categories:

  • Incorrect In-App Settings: Motion detection might be disabled, sensitivity set too low, or activity zones configured improperly.
  • System Is 'Disarmed': Your security system or camera might be set to a mode where motion detection is intentionally turned off.
  • Blocked Notifications: Your phone's operating system may be preventing the SmartThings app from sending you notifications.
  • Physical Obstruction: The camera's view or sensor may be blocked or affected by environmental factors.

How to Troubleshoot Samsung Motion Detection

Follow these steps in order to find and fix the problem. After each adjustment, test by walking in front of the camera.

1. Check the Core Settings in the SmartThings App

Start by ensuring everything is enabled correctly within the app itself.

  • Turn On Motion Detection: Select your camera in the SmartThings app, go to its Settings, and find the Motion Detection menu. Make sure the main toggle switch is ON.
  • Increase Motion Sensitivity: Within the same menu, you will see a sensitivity slider or setting (e.g., Low, Medium, High). If it is set too low, it will only trigger on very large or close movements. Set it to High for testing. You can always reduce it later if you get too many false alerts.
  • Verify Armed/Disarmed Status: Check the main dashboard of your security app. If the system is in a 'Disarmed' or 'Home' mode, motion alerts might be suppressed by design. Set the system to 'Armed' or 'Away' to ensure detection is active.

2. Review Your Activity Zones

Activity Zones are a powerful feature, but a common source of error.

  • Check Zone Placement: If you have configured Activity Zones, go back into the settings menu. Ensure the zones you have drawn accurately cover the areas where you expect motion to be detected, such as walkways or entrances.
  • Temporarily Disable Zones: To rule out a zone-related issue, try disabling the Activity Zones feature entirely. If the camera starts detecting motion everywhere, you know the problem was with how your zones were drawn. You can then re-configure them more carefully.

3. Verify Your Phone's Notification Settings

Sometimes the camera is detecting motion, but the alerts aren't making it to your phone.

  • In-App Notification Settings: First, check inside the SmartThings app's main settings for a 'Notifications' menu. Ensure notifications are enabled globally.
  • Phone System Settings (Crucial):
    • For iPhone: Go to Settings > Notifications > SmartThings. Make sure 'Allow Notifications' is on, and that you have 'Lock Screen', 'Notification Centre', and 'Banners' enabled.
    • For Android: Go to Settings > Apps > SmartThings > Notifications. Make sure all categories of notifications are turned on and not set to 'Silent'.
  • Check Do Not Disturb Mode: Make sure your phone is not in 'Do Not Disturb' or a 'Focus Mode' that silences notifications from the SmartThings app.

4. Check for Physical and Environmental Issues

Rule out any physical problems with the camera's placement.

  • Clean the Lens: A dirty or smudged camera lens can sometimes interfere with the sensor's ability to detect motion clearly. Wipe it gently with a soft, microfibre cloth.
  • Look for Obstructions: Is there a new object, like a plant or a piece of furniture, blocking the camera's view of the target area?
  • Consider Lighting: While modern cameras are very capable, very poor lighting conditions or direct sunlight shining into the lens can sometimes impact the effectiveness of motion detection.

By systematically working through these settings, you can pinpoint the reason your motion detection isn't working and restore your camera's ability to alert you when it matters most.

Frequently Asked Questions

This is usually due to incorrect settings. The motion sensitivity might be set too low, the camera may be in 'disarmed' mode, or you may have configured activity zones that exclude the area where motion is happening. Notification settings on your phone could also be blocking the alerts.

In the SmartThings app, go to your camera's settings and find the 'Motion Detection' menu. Ensure the master toggle is on. Then, check the sensitivity level. If it's on 'Low', it may not pick up distant or subtle movements. Try increasing it to 'Medium' or 'High' for testing.

Activity Zones tell your camera to only watch for motion within specific parts of the frame. If you have zones set up, make sure they are drawn correctly over the areas you want to monitor. Any motion happening outside these zones will be ignored. Try disabling the zones temporarily to see if detection starts working.

Yes, this is a common issue. Go to your phone's main settings, then 'Notifications' > 'App Notifications' > 'SmartThings'. Ensure that all notifications for the app are allowed and that it's not set to 'Silent' or 'Deliver Quietly'. Also, check the in-app notification settings to make sure they are enabled for your camera.
