Dear TP‑Link Support Team,

I am experiencing several issues with the Tapo TC70 v5 when using it within a surveillance system (Frigate + go2rtc). These problems occur only with this model; other Tapo cameras work correctly under the same conditions.

1. Video stream stops when enabling two‑way audio

• When viewing the camera through MSE (Media Source Extensions), the video stream works normally as long as two‑way audio is not enabled.

• As soon as I activate the microphone to speak through the camera, the system automatically switches to WebRTC, and at that moment the video stops working completely in MSE.

• If I view the camera directly in WebRTC, both video and two‑way audio work correctly.

• This behavior is exclusive to the TC70 v5; other Tapo models do not show this issue.

Summary:

• MSE + video → works

• MSE + microphone enabled → video stops

• WebRTC + microphone → works normally

• Issue exclusive to TC70 v5

It appears that the TC70 v5 video stream is not handled correctly when two‑way audio is activated, causing the MSE stream to stop generating video.

2. Intermittent watchdog errors

In addition to the issue above, the TC70 v5 also generates intermittent watchdog errors during normal operation. These errors indicate that the camera stream stops producing new segments for long periods, forcing the system to restart the FFmpeg recording process. This instability does not occur with other Tapo models under identical network and system conditions.

Here are the three most recent log entries recorded by the system:

 

2026‑02‑26 21:46:30 — watchdog.Salon_1: Waiting for ffmpeg to exit gracefully…

2026‑02‑26 21:46:41 — watchdog.Salon_1: No new recording segments were created for Salon_1 in the last 120s. restarting the ffmpeg record process…

2026‑02‑26 21:47:02 — watchdog.Salon_1: No new recording segments were created for Salon_1 in the last 120s. restarting the ffmpeg record process…

 

These repeated watchdog events suggest that the camera intermittently stops sending video data, even though the network connection remains stable.

Request

I kindly ask you to review these issues and confirm:

• Whether this is a firmware bug or compatibility problem specific to the TC70 v5.

• Whether there is a firmware update, beta version, or configuration adjustment that can resolve:

  • The loss of video when enabling two‑way audio in MSE.

  • The intermittent watchdog errors and stream interruptions.

Thank you in advance for your assistance. I look forward to your response.

 

Kind regards,

HarryTuttle
