How to Fix Inaccurate Lorex Person Detection
Lorex cameras with smart person detection are designed to provide you with more relevant security alerts, filtering out unimportant motion from pets, vehicles, or swaying trees. However, if you are receiving false alarms or, worse, no alarms for actual people, it can undermine your security. This guide will help you troubleshoot and fine-tune your Lorex camera's person detection for better accuracy.
Common Causes of Incorrect Person Detection
Understanding why the detection might be failing is the first step to fixing it.
- Camera Placement and Angle: An improper viewing angle or mounting height can make it difficult for the camera's AI to distinguish a person from other objects.
- Sensitivity Settings: If the sensitivity is set too high, the camera may trigger alerts for minor movements. If it's too low, it might miss genuine events.
- Environmental Factors: Moving shadows, rustling leaves, rain, or insects can sometimes be misinterpreted by the detection algorithm.
- Outdated Firmware: Lorex regularly releases firmware updates that include improvements to their detection algorithms.
- Poor Lighting: Insufficient light or strong backlighting can obscure details, making it harder for the camera to identify a person.
Step-by-Step Guide to Improve Accuracy
Follow these steps to systematically troubleshoot and enhance your camera's performance.
1. Optimise Camera Placement
The position of your camera is crucial for accurate person detection.
- Height: Mount your camera between 2-3 metres (7-10 feet) off the ground.
- Angle: Angle the camera downwards slightly. This provides a clear view of a person's entire body as they approach.
- Avoid Obstructions: Ensure there are no large objects, like plants or pillars, blocking the camera's line of sight.
- Lighting: Avoid pointing the camera directly at a light source (like the sun or a porch light) as this can create silhouettes and reduce accuracy.
2. Adjust Detection Settings in the Lorex App
Fine-tuning the software settings can make a significant difference.
- Set Motion Zones: Draw specific zones where you want the camera to look for people. Exclude areas with constant irrelevant motion, such as a busy street or a neighbour's garden.
- Adjust Sensitivity: In your device settings, find the 'Smart Detection' or 'Motion Detection' menu. Try lowering the sensitivity level. We recommend making small adjustments and testing the results before making further changes.
3. Update Your Camera's Firmware
Keeping your camera's software up to date is essential.
- Open the Lorex app and go to your camera's settings.
- Look for a 'Firmware' or 'Device Update' section.
- If an update is available, follow the on-screen instructions to install it.
4. Keep the Lens Clean
A dirty or smudged lens can obscure the camera's view, leading to poor detection performance, especially at night. Gently wipe the lens with a clean, soft microfibre cloth.
Final Considerations
By optimising your camera's physical setup and software settings, you can dramatically improve the accuracy of its person detection feature. This ensures you receive timely and relevant alerts, giving you peace of mind that your property is properly monitored.
