How to Improve Aiphone's Person Detection Accuracy
Aiphone video intercoms with person detection are designed to provide intelligent alerts, notifying you when someone is actually at your door, rather than every time a car drives by or a cat walks across your path. However, if you're being bombarded with false alerts or the system is missing genuine events, some simple adjustments to the settings can dramatically improve its accuracy.
This guide will help you understand why your Aiphone system might be generating incorrect person detection alerts and how to configure it properly to ensure you only receive notifications that matter.
Understanding the Causes of False Detections
When your Aiphone system sends a false alert, it's usually for one of these reasons:
- Sensitivity is Too High: The system is overly sensitive and interprets non-human motion (e.g., shadows, animals, swaying trees) as a person.
- Detection Area is Too Broad: The monitoring area includes public spaces like a pavement or street, leading to alerts for passers-by.
- Poor Camera Angle: The door station is mounted too high or at an awkward angle, making it difficult for the algorithm to correctly identify a human form.
- Complex Lighting: Rapid changes in light, such as from passing clouds or car headlights at night, can sometimes trigger an alert.
- Outdated Firmware: The device's software may have known bugs that have been fixed in a later version.
A Step-by-Step Guide to Reducing False Alerts
You can configure these settings through your Aiphone system's web interface or dedicated programming software.
1. Adjust the Detection Sensitivity
This setting controls how much movement is required to trigger an analysis. Finding the sweet spot is key.
- Log in to your Aiphone system's configuration menu.
- Navigate to the Motion Detection or Person Detection settings for the relevant door station.
- You will see a sensitivity slider or numerical value (e.g., 1-100).
- If you are getting too many false alerts, reduce the sensitivity in small increments (e.g., by 10 points).
- Save the setting and test the system for a day to see if the number of false alerts has decreased. Continue to adjust as needed.
2. Define a Precise Detection Area
This is the most effective way to eliminate alerts from areas you don't care about.
- In the same settings menu, find the Detection Area or Activity Zone option.
- You will see the camera's live view, often overlaid with a grid.
- Clear any existing default zone that covers the entire screen.
- Carefully draw a new, smaller zone that only covers the area of interest, such as your doorstep, the path leading to your door, or a designated package drop-off spot.
- Crucially, exclude any public areas, busy roads, waving flags, or large bushes that move in the wind.
- Save your new detection area.
3. Review Camera Placement
While you may not be able to easily move the door station, it's important to understand its impact.
- Optimal Height: For best results, the camera should be mounted so it has a clear, unobstructed view of a person's head and shoulders as they approach.
- Avoid Severe Angles: A camera pointing straight down from a high position will see the top of a person's head, which is much harder for the AI to identify as a person than a more direct, face-on view.
4. Update Your System's Firmware
Manufacturers constantly work to improve their detection algorithms. A firmware update can provide a significant boost in accuracy.
- Check the official Aiphone support website for the latest firmware for your specific model (e.g., IXG Series).
- Download the firmware and follow the provided instructions to update your system. This often resolves known bugs and improves overall performance.
By methodically adjusting these settings, you can greatly enhance the reliability of your Aiphone's person detection feature, ensuring your notifications are both timely and relevant.
