Fine-Tuning Your Smart Alerts
Ezviz cameras with person detection offer a significant upgrade over traditional motion sensors. By using Artificial Intelligence (AI) to analyse movement, they aim to alert you only when a person enters the frame, filtering out the "noise" from passing cars, swaying branches, or family pets. However, when this technology doesn't work as expected—either missing people or sending false alarms—it can undermine your sense of security. If your Ezviz camera's person detection is proving unreliable, this guide will help you calibrate it for better accuracy.
Common Reasons for Incorrect Person Detection
AI is smart, but it's not perfect. Several factors can cause your Ezviz camera to make mistakes:
- Poor Camera Placement: If the camera is too high, too low, or angled poorly, it may struggle to recognise the human form correctly.
- Complex Backgrounds: Constantly moving objects, like rustling trees, flags, or shadows, can sometimes be misinterpreted by the algorithm.
- Lighting Conditions: Sudden changes in light, deep shadows, or strong glare can obscure details and confuse the AI.
- Outdated Firmware: Ezviz regularly refines its detection algorithms. An older firmware version might be less accurate than the latest release.
- Incorrectly Configured Zones: If your motion detection zones are not set up properly, the camera may be monitoring areas you don't intend it to, leading to irrelevant alerts.
Step-by-Step Guide to Improve Ezviz Detection Accuracy
Work through these solutions to reduce false positives and ensure you're alerted to what really matters.
1. Optimise Camera Placement and Angle
This is the most critical step. A well-placed camera gives the AI the best possible information to analyse.
- Height: Install your camera between 2 to 3 metres (7-10 feet) off the ground.
- Angle: Angle the camera downwards slightly. This provides a clear view of people as they approach and helps to distinguish their shape. Avoid pointing the camera directly at the horizon.
- Clear View: Ensure there are no immediate obstructions like tree branches, walls, or large decorations blocking the main detection area.
2. Configure Detection Zones and Sensitivity
Tell your camera exactly where to look and how sensitive it should be.
- Open the Ezviz app and select your camera.
- Go to Settings > Notification > Detection Area (or similar wording).
- Draw a specific zone covering only the area you want to monitor for people, such as a walkway or doorway. Deselect areas with constant motion, like a busy street or a neighbour's garden.
- Next, go to Detection Sensitivity. If you are getting too many false alerts, lower the sensitivity. If it's missing real events, increase it. Adjust it one level at a time and test the results.
3. Update Your Camera's Firmware
Ensure your camera is running on the latest software.
- In the Ezviz app, go to your camera's Settings.
- Look for 'Device Version' or 'Firmware Update'.
- If a new version is available, proceed with the installation. This can provide significant improvements to the detection AI.
4. Ensure Proper Lighting Conditions
Good lighting is crucial for accurate detection, especially at night.
- Ensure the area is reasonably well-lit. If the camera has a built-in spotlight, check that it is functioning correctly.
- Avoid pointing the camera directly at a light source, as this can create glare and deep shadows that hide detail.
5. Reboot Your Ezviz Camera
A simple power cycle can sometimes resolve temporary software glitches. Unplug the camera from its power source for 30 seconds, then plug it back in. This forces the internal processor to restart and can clear up minor issues.
