Annke Person Detection Not Working Correctly? Let's Fix It
The AI-powered person detection feature in modern Annke cameras is a fantastic tool for reducing the flood of irrelevant motion alerts. However, when it doesn't work as expected—either bombarding you with false alarms or missing people entirely—it can be more of a nuisance than a help.
Getting person detection right is a balancing act between software settings and the camera's physical environment. This guide will help you understand why your Annke's person detection might be failing and provide clear, actionable steps to fine-tune it for maximum accuracy.
Why Person Detection Can Be Inaccurate
Artificial intelligence is smart, but it's not perfect. It analyses changes in pixels to identify the shape and movement patterns of a person. Inaccuracy usually stems from one of two issues:
- False Positives: The camera thinks it sees a person when it's actually something else (e.g., shadows, animals, swaying trees, car headlights).
- False Negatives: The camera fails to identify a person who is genuinely there (e.g., they are too far away, partially obscured, or moving too quickly).
Troubleshooting False Person Detection Alerts
If you're getting too many notifications for things that aren't people, work through these solutions.
1. Adjust Detection Sensitivity
This is your primary tool. A sensitivity level that is too high will cause the AI to over-analyse and flag non-human objects.
- How to Fix: Log into your Annke system via the app or web interface. Navigate to the "Event" or "Detection" settings for the specific camera. Find the "Person Detection" or "Smart Detection" settings and locate the sensitivity slider. Lower the sensitivity by 10-15% and monitor the results for a day before adjusting again.
2. Configure Activity Zones
Tell your camera exactly where to look for people.
- How to Fix: In the same detection settings menu, find the "Activity Zone" or "Detection Area" option. Draw a precise zone that covers only the areas where you expect to see a person, like a garden path or a doorway. Exclude areas with constant irrelevant motion, such as public footpaths, roads, or bushes that sway in the wind.
3. Check for Environmental Interferences
Sometimes the camera's view is the problem.
- How to Fix:
- Cobwebs and Insects: Clean the camera lens and housing. Spiders and insects are attracted to the camera's infrared lights at night and can crawl across the lens, triggering alerts.
- Light Changes: Avoid pointing the camera directly at a source of bright, changing light (like streetlights or reflective surfaces) that can create sudden shadows.
Troubleshooting Missed Person Detections
If your camera isn't picking up people when it should, try these steps.
- Increase Sensitivity: The opposite of the fix above. The sensitivity may be too low to register a person, especially if they are far from the camera. Increase it incrementally.
- Check Camera Angle and Distance: For optimal performance, a person should occupy a reasonable portion of the frame. If the camera is mounted too high or is trying to cover too vast an area, the person may appear too small for the AI to analyse confidently.
- Update Firmware: Check for firmware updates for your Annke camera or NVR. Manufacturers constantly refine their AI algorithms, and an update can often bring significant improvements to detection accuracy.
By methodically adjusting these settings, you can dramatically improve the reliability of your Annke camera's person detection, ensuring you only get the alerts that truly matter.
