Motion detection is one of the most important features of a smart home security system. For homeowners, getting notified and know what’s happening around the premise is important. There are a few issues with this feature, such as: motion camera is being unresponsive, motion detection not working, detecting motion but not recording, or delay in motion capture. If that’s the case, what should you do to fix these problems?

Motion notifications are a must-have feature in nowadays security systems.

Motion notifications are a must-have feature in nowadays security systems.

There are two main types of motion sensors in a surveillance system, one triggers motion by measuring changes in pixels and relying on motion algorithm, known as optical-based motion sensor; another sets off motion alarms by detecting body heat and infrared energy, known as PIR motion sensor.

Both types could suffer motion miss-out when there is a network connection problem. Technical issues like firmware, software, and placement can also be blamed for cameras’ inability to trigger motion alert, record motion or push notifications.

How to fix motion detection not working

  • Tip 1. Enable or reconfigure motion detection
  • Tip 2. Update firmware
  • Tip 3. Update monitoring software
  • Tip 4. Change cameras’ placement or pointing angle

1. Activate and reconfigure motion detection

Some users might have experienced that their security camera is not reacting to people walking into its frame, nor does the camera capture any motion events. In such case, it’s likely that user forgets to configure motion detection setting during setup stage. Some security cameras will initiate motion detection by default while some are not.

Thus, make sure you have enabled motion detection in the camera’s settings, desktop software or mobile apps. If you did all of the above and the problem is still there, readjust sensibility and change other motion detection settings like increasing sensibility to object size, increasing contrast to the max, resetting geo-fencing, resetting motion detection schedule or resetting threshold level.

Try to reactivate and re do the configurations of your security systems.

2. Update firmware

Many security cameras will start recording when movement is detected. Behind such technology lies in the complicated algorithm which will calculate the pixies difference between different frames. However, once the algorithm is not properly calculated, situations like cameras are not recording movements even there are people approaching or walking pass, will occur.

Updating security camera firmware or the firmware of NVR/DVR to the latest version could fix potential bugs that have been meddling with the motion detection or push notification. Moreover, for security reasons it’s always recommended to keep your security devices up-to-date.

3. Update monitoring software

Monitoring software or apps play a role in motion capture and motion alert triggers since you need them to enable motion detection and trigger in the first place, or not for some of them trigger motion by default. Any bugs or unresolved technical problems in the monitoring software or apps could have an impact on the general performance of your security cameras or systems.

Upgrading your apps or software to an updated version and gets rid of this nagging problem once for all. Always check if your monitoring app has a new release.

4. Change cameras’ placement or pointing angle

Security cameras with built-in PIR motion sensor, could see cameras do detect motion but fail to record or capture movement. Or cameras can’t detect or record motions through glass or window glass panel. In such cases, avoid placing motion detection security cameras behind the glass window especially cameras with a PIR motion sensor; do place wireless motion sensor security cameras closer to a WiFi router or hotspot.

The object from afar is relatively easier to be miss out, so don’t expect security cameras to pick up every movement within its field of view. Focusing on strategic areas for motion detection helps achieve maximal peace of mind as well as reducing unwanted false alarms.


Normally, people infuriate about getting loads of false alarm alerts and getting their storage/inbox flooded with notifications, but not so much furious when not getting any notification or motion alert. However, more often than not, no news is not always good news, especially if you are not storing footage to an on-site NVR or uploading to a cloud server, missing out such important forensic video evidence is unnerving.

Technically speaking, many cheap or cheapish security cameras, despite having built-in motion sensors, could experience problems like motion detection not working, frequent motion triggers or missing motion capture after months of use. Buying security cameras from top CCTV camera brands could reduce such risks and guarantee long-term stability in performance.
