Camera Not Detecting Motion? Here’s How to Fix It

Someone walks up your drive, reaches the front door and leaves again—but your camera records nothing. When you find your camera not detecting motion, it is easy to assume the sensor has failed. In many cases, though, the cause is a disabled setting, a poorly placed activity zone, an unsuitable mounting angle or a recording rule that needs attention.

This guide helps you separate motion-detection problems from missing recordings and phone alerts. You will work through the checks in a sensible order, from power and app settings to camera position, night conditions and storage. The advice is tailored to UK homes, including terraces, flats and properties close to public pavements.

Quick Answer: Why Is My Camera Not Detecting Motion?

A camera may not detect motion because of:

• Motion detection being disabled
• Low sensitivity settings
• Incorrect activity zones
• Movement outside the detection range
• Power, recording, or notification issues

Check the camera angle and settings, then run a walk test after making adjustments.

First Check: Is the Problem Detection, Recording or Alerts?

Before changing the sensor settings, look closely at what failed. Detection, recording and notification are separate parts of the process, so an event in the app proves the camera detected something even if your phone stayed silent.

A weak connection can delay thumbnails, recordings or notifications without proving that the physical sensor missed the person. Open the event timeline and live view first. This quick distinction can save you from repeatedly adjusting a sensor that is already working.

Common Reasons Your Camera Stops Detecting Motion

The likely cause usually falls into one of four areas. Work through them methodically rather than raising sensitivity to its highest level straight away.

Detection and Security Modes

Motion detection may be disabled even when live view still works. The selected security mode (such as Home, Away or a custom mode) can affect whether events are recorded or notifications are sent.

Check whether the correct camera is included in the active mode and whether detection, recording and notification functions are enabled.

Sensitivity, Detection Types and Activity Zones

Detection settings can affect which movements trigger events. Low sensitivity may miss smaller or distant movements, while restrictive detection types may ignore certain subjects.

Incorrect activity zones can also exclude areas where movement occurs, such as the edge of a driveway or pathway.

Placement, Range and Obstructions

Camera position plays an important role in motion detection. A steep mounting angle, excessive distance or blocked view can reduce the area where movement is detected.

Objects such as plants, decorations, cobwebs or dirt may interfere with detection. For cameras using PIR sensors, placement behind glass or reflective surfaces can also affect performance.

Power, Software and Environmental Conditions

Power issues, unstable connections or outdated software may affect motion events. Environmental conditions such as darkness, rain, fog, glare or moving objects can also reduce detection accuracy.

For solar-powered cameras, factors such as limited sunlight exposure or shading may affect available power and overall performance.

How to Fix a Camera Not Detecting Motion

Follow these troubleshooting steps in order. After each major change, run a quick walk test to confirm whether detection has improved. Changing one setting at a time makes it easier to identify the cause.

1. Check That the Camera Is Powered and Online

Start with the basics. Check the battery level, cable connection, live view and device status in the app. If multiple cameras are affected, check your router or HomeBase connection as well.

For solar cameras, clean the panel and make sure nearby objects, such as eaves or foliage, are not blocking sunlight. If live view is unstable or slow, fix the connection issue before adjusting motion settings.

2. Enable Motion Detection, Recording and Notifications

Confirm that motion detection, recording and notifications are enabled:

• Open the eufy app and select your camera.
• Check that Motion Detection is turned on.
• Open the active security mode and confirm Video Record and Push Notification are enabled.

Also check your phone’s notification permissions, quiet schedules and battery optimisation settings, as these can prevent alerts from appearing.

3. Adjust Sensitivity and Detection Type

Set sensitivity to a medium level and test the camera at different distances. Increase it gradually if movement is missed.

During testing, use a broader detection option such as all motion. If alerts return, the previous human, vehicle or pet detection setting may have been too restrictive for the environment.

4. Check or Rebuild the Activity Zone

Check whether the activity zone covers the areas where movement actually occurs. A zone may accidentally exclude important areas, such as the bottom of the frame, a gate or the edge of a driveway.

Temporarily remove the zone and test again. If detection works, redraw the zone while avoiding unnecessary areas such as roads, public spaces or moving objects like trees.

5. Correct the Camera’s Position and Angle

Make sure the camera is positioned to capture the main movement path. Motion detection range varies by model, mounting height and angle, so avoid placing the camera too far from the area you want to monitor.

For PIR-based cameras, avoid mounting behind glass. Remove obstacles such as leaves, decorations or cobwebs, and test movement from different directions to identify blind spots.

6. Test Detection During the Day and at Night

Repeat the same motion test after dark. Check that night vision works correctly and that nearby walls, windows or lights are not causing reflections.

Clean the lens and remove water droplets or dirt that may affect detection. Some battery cameras may have different detection performance at night depending on the model and environment.

7. Check the App, Firmware, Wi-Fi and Storage

Update the eufy app and camera firmware, then check the signal strength at the installation location.

If multiple devices are affected, restart the router or HomeBase. Weak Wi-Fi may delay alerts or recordings even when motion detection itself is working.

Also confirm that storage is available and event filters are not hiding recorded clips.

8. Restart, Re-add or Reset the Camera

Restart the camera, HomeBase or router, then test again. This can resolve temporary connection or software issues without changing your settings.

If the problem continues, remove and reconnect the camera in the app. Save important zones and schedules first, as a factory reset will erase existing settings and require a new setup.

When Should You Contact Support?

Contact support when controlled testing still produces no event after you have checked settings, restarted the system and added the camera again. Support is also appropriate if the device has visible damage, internal condensation, repeated offline periods despite a reliable connection, or a problem affecting several cameras after an update.

Before getting in touch, note the camera model, firmware and app versions, active mode, test distance, time of day and recent troubleshooting. Screenshots of settings and a short description of the route used in your walk test can make diagnosis quicker.

Motion Detection Tips for UK Homes

UK properties often place a front door or small drive close to a public pavement. That makes careful positioning useful for both relevant alerts and household privacy.

• Terraced and semi-detached homes: Keep the activity zone on your gate, front path and doorstep rather than the full street view.
• Flats and shared entrances: Avoid covering neighbours’ doors and communal areas where possible. Confirm any building or tenancy rules before mounting equipment.
• Seasonal changes: Recheck zones when hedges grow, leaves fall or low winter sun creates glare. Clean the lens and solar panel after wet or windy spells.
• Privacy controls: Use privacy zones to mask neighbouring windows, gardens and areas that do not need monitoring.

Position cameras to capture your property where practical. If footage includes someone else’s property, a public area or a communal space, UK data protection rules for home CCTV may apply because images and voices can be personal information.

eufy Security Cameras for Smarter Motion Coverage

If your Security Cameras still miss important events after checking settings, activity zones and placement, the limitation may come from the cameras’ coverage or detection capability. Choosing a camera with a wider viewing angle, smart tracking and AI-powered detection can help reduce blind spots and improve motion monitoring.

eufyCam S4: For Larger Drives and Multi-Angle Tracking

The eufyCam S4 is designed for larger outdoor areas where a traditional fixed camera may leave blind spots, such as driveways, front gardens and entrances. It combines a 4K fixed bullet camera with a 2K dual-lens PTZ camera, allowing you to monitor a wide scene while also tracking movement across different areas.

Key features:

• Dual-camera design: The 4K bullet camera provides a 130° wide-angle view, while the 2K PTZ camera supports 360° pan coverage, helping capture movement across a larger area.
• Smart tracking: The PTZ camera can pan, tilt and zoom to follow detected subjects and keep important activity in view.
• AI-powered detection: Human, vehicle and pet detection helps focus alerts on more relevant events.
• Flexible recording options: Continuous recording is available in supported setups with direct power, while HomeBase S380 provides expanded storage and additional smart features.

For homeowners who often miss events because people move outside the camera’s viewing area, the eufyCam S4’s combination of wide coverage and tracking capability can provide more complete monitoring.

SoloCam S340: For Flexible, Wire-Free Coverage

The eufy SoloCam S340 is suited for areas where installing a wired camera is difficult, such as gardens, side paths or locations without convenient power access. Its dual-camera system combines a 3K wide-angle lens with a 2K telephoto lens, helping capture both the overall scene and more detailed views.

Key features:

• Dual-lens design: The combination of wide-angle and telephoto lenses helps cover larger areas while maintaining clearer details at important points.
• Wide movement coverage: With 355° horizontal pan and 70° tilt, the camera can adjust its view to follow activity around the monitored area.
• Zoom capability: 8× hybrid zoom helps users check details when reviewing detected events.
• AI detection: On-device AI helps detect humans and vehicles to reduce unnecessary alerts.
• Flexible installation: The solar-powered design helps support placement in outdoor locations where running cables is inconvenient.

As a battery-powered camera, the SoloCam S340 is designed mainly for event-based recording rather than continuous recording, making it a practical choice for users who need flexible installation and reliable motion monitoring.

Conclusion

A camera not detecting motion does not automatically need replacing. A short, controlled test can reveal whether the gap lies in sensing movement, saving the event or delivering the alert. That distinction matters because each problem calls for a different fix.

Once the camera responds reliably, keep the setup stable for a few days and review genuine events rather than test clips alone. Seasonal light, plant growth and changes to the route around your home may alter performance over time. Revisit the angle, zones and sensitivity when the environment changes, while keeping coverage focused on the area you genuinely need to monitor.

FAQs

Why Does My Camera Detect Motion Only When Someone Is Close?

Your camera may detect people only at close range because its PIR sensor responds to changes in heat rather than movement alone. A distant person creates a smaller heat change, especially when walking directly towards the camera. Low sensitivity, excessive mounting height, a steep angle or an obstruction can also shorten the detection range. Increase sensitivity gradually, adjust the angle and test the camera at several distances.

Why Is My Camera Not Detecting Motion at Night?

Night-time detection may fail because image-based systems have less visual contrast in low light. Although PIR sensors do not require visible light, their performance can vary when the temperature difference between a person and the surroundings is small. Low sensitivity, a dirty lens, obstructed infrared LEDs, glare or limited night-time range may also contribute. Clean the camera, review its settings and run a walk test after dark.

Can Weak Wi-Fi Stop a Camera from Detecting Motion?

Weak Wi-Fi may not stop the camera’s physical sensor from detecting movement, but it can prevent or delay alerts, thumbnails and cloud recordings. If the connection drops completely, the camera may appear offline and cannot send activity to your phone. Check the signal at the installation point, restart the router or HomeBase and confirm whether events are still being saved locally before adjusting the motion sensor.

Why Is My Camera Recording Events but Not Sending Notifications?

If recordings appear in the app but notifications do not, the camera is detecting motion correctly and the problem is likely related to alert settings. Check whether push notifications are enabled for the camera and active security mode. You should also review your phone’s notification permissions, Focus or Do Not Disturb settings, battery optimisation and any alert schedules. Restarting or updating the app may resolve temporary notification delays.

Does Rain Affect Security Camera Motion Detection?

Rain can affect motion detection by obscuring the camera’s view or producing unwanted alerts. Droplets passing close to the lens may appear as large movements, while infrared light can reflect from rain at night and create bright spots. Water on the lens may also reduce image clarity. Keep the lens clean, adjust the camera angle if possible and check its detection performance again after severe weather.
