Hi,
The basic camera detection system relies on identifying changes in images between different frames. However, movements of objects like bushes and flags can cause significant image alterations and lead to unnecessary detections, making it challenging to avoid them.

To minimize unnecessary detections, follow these steps:
1. Open your Tapo app and navigate to your camera page. Tap the Settings icon at the top right corner of the Live View page to access the Device Settings page.
2. If your goal is to detect only people, enable the Person Detection feature on the camera's Device Settings>Detection page and turn off the Motion Detection feature.
3. Based on your use conditions, adjusting the detection zone and sensitivity may help reduce too many detections.
1) The Detection Zone allows you to define a specific area that you want your camera to detect, everything outside of the zone will be ignored.
2) Setting the detection sensitivity to a lower level can also help reduce the detections, but it may defeat the purpose of true motion detection. You may find that you’re missing alerts when there is a real person or animal in the camera’s view.
4. You may adjust the installation angle to be away from the false alerts trigger. Try to avoid pointing the camera at busy public areas like busy streets, sidewalks, etc.
5. Use a camera that has a PIR sensor built-in, such as the Tapo Battery Camera like Tapo C400/C420/C425.
For detailed instructions, please refer to this article: How to reduce motion detections from rain, snow or insects,etc
 

You can also add a privacy zone on the Tapo app>camera's Device Settings>Video & Display>Privacy Zone page to avoid detecting the movements of the bushes and flags.

Best Regards
