We understand that you are experiencing human detection problems with your EZVIZ door viewer. Regarding this, here are some troubleshooting tips that we suggest you try.

1. Ensure the firmware of your device is up to the latest. (Check firmware version in device Settings > Device Information. If not the latest, you would be prompted to upgrade it.)

2. Check sensitivity settings. In device settings > Intelligent Detection > Detection Sensitivity, under PIR Infrared Detection, move the slider to the right to increase the sensitivity level.

3. Try to turn off Loitering Detection or decrease the period (also in device Settings > Intelligent Detection), as the longer the period is, the more time the device will need to trigger detection.

4. Try to select High-Performance Mode (in device Settings > Battery> Working Mode) and check whether you will receive more alarms.

5. Try horizontal movement and see whether the device would be triggered, as all PIR sensors are more sensitive to horizontal movements than vertical movements.

6. Try to reset the device
