Tapo D210(US/EU/JP/KP) V1.0

TD21(US/UK) V1.0

Description

Recently, you might have noticed that the Tapo D210 V1 or TD21 V1 doorbell has stopped detecting motion or recording events, except when you are watching the live stream in the Tapo app, where detection and recording work normally.

Troubleshooting Suggestions

Set the doorbell's detection sensitivity to the maximum level, then run the detection-range test on your doorbell. *We recommend conducting multiple tests to avoid coincidental or inconsistent results.

How to test the detection range of Tapo battery camera

If the doorbell cannot detect anything during testing, or if the detection range is noticeably limited—for example, within just 1–2 meters, the issue is likely hardware‑related, specifically with the PIR sensor. In this case, a replacement will be needed. To proceed with the warranty, please contact the retailer or local TP-Link support. Contact Technical Support
