Heimvision Person Detection Wrong? A Guide to Accurate Alerts
The "humanoid detection" or "person detection" feature on Heimvision cameras is designed to be a smart filter, ensuring you are only alerted to the events that matter most. However, when this feature is inaccurate, it can either bombard you with false alarms or fail to detect a person when it should. If you're frustrated with your camera's performance, this guide will provide you with the steps to fine-tune its settings for much better accuracy.
Getting person detection right involves a combination of optimising the camera's software settings and ensuring its physical placement is ideal for the AI to do its job effectively.
Why Your Person Detection is Inaccurate
Several factors can confuse the camera's algorithm, leading to poor results:
- Sensitivity Overload: If the motion sensitivity is set too high, the algorithm may trigger on pets, wildlife, or even moving shadows.
- Poor Camera Angle: A camera that is mounted too low, too high, or pointing towards a very busy background can struggle to isolate and identify a human shape.
- Challenging Lighting: Strong backlighting (pointing towards the sun), deep shadows, or lens flare can obscure details, making it difficult for the AI to work correctly.
- Outdated Firmware: The detection algorithms are constantly being refined. An older firmware version may be less accurate than the latest release.
- Obstructions: Trees, bushes, or other objects that partially block the view can lead to misinterpretations.
How to Calibrate Heimvision Person Detection
Follow these steps to systematically improve the accuracy of your camera's alerts.
1. Adjust Sensitivity and Detection Settings
This is your most powerful tool for optimisation.
- Open the Heimvision app and select the camera you wish to adjust.
- Tap the 'Settings' icon.
- Go to 'Alarm Setting' or a similarly named menu.
- Enable 'Humanoid Detection': Make sure this specific feature is toggled on. If it's off, you will just get generic motion alerts.
- Adjust Motion Sensitivity: You will likely see a slider for sensitivity (e.g., Low, Medium, High). If you are getting too many false alerts, reduce the sensitivity. If the camera is missing real events, increase the sensitivity. It may take some trial and error to find the best setting for your environment.
2. Set Up Motion Detection Zones
This feature is incredibly useful for eliminating false alarms.
- In the detection settings, look for an option like 'Motion Zone' or 'Activity Zone'.
- This will allow you to draw a specific area on the screen where you want the camera to look for motion.
- Draw the zone to cover your path or doorway, but exclude areas like a public footpath, a busy road, or a tree that sways in the wind. This tells the camera to ignore movement in those excluded areas.
3. Optimise Camera Placement
The physical position of your camera matters.
- Height: Mount the camera at a height of 2 to 3 metres.
- Angle: Point it slightly downwards. This gives the camera a clear perspective of a person's entire body as they approach.
- Clear Line of Sight: Ensure there are no major obstructions in the detection zone you've set.
4. Update Your Firmware and App
As mentioned, software improvements can make a huge difference.
- App: Regularly check your phone's app store for updates to the Heimvision app.
- Firmware: In the camera's settings within the app, check the 'Device Information' or 'Firmware Version' section for any available updates and install them.
By carefully adjusting these settings, you can teach your Heimvision camera what to look for and what to ignore, leading to more reliable, accurate, and meaningful person detection alerts.
