Troubleshooting Tapo c120 cameras all experiencing choppy/laggy RTSP streams after 1.3.1 firmware
I have 8 of these cameras, all purchased and set up about 1.5-2 months ago. I have them all recording to sd, and also using my synology nas / surveillance station to record/stream them via RTSP (tcp).
Before the 1.3.1 firmware, they were working perfectly. Nice, smooth real-time views, however, after the 1.3.1 update they are showing a frame every 2-4 seconds, and randomly lagging behind for hours.
Changing hardware acceleration did not help with the quality.
Within synology ss, it 'found' them with onvif and I do have them set up as Tapo c120 cameras in there. I've also removed, then tried adding as generic onvif.
The c110s and c210s I have are still running smoothly in synology ss in 'live-view'.
Viewing the c120s from the tapo app in live-view seems fine. For me, it's something with the RTSP.
I've seen others (on reddit) with similar issues when trying to view with RTSP.

Tapo C120 and Tapo C121 ONVIF and RTSP Behaviors Since Latest Update
Hey Everyone!
We received word from our development team about the reported behaviors resulting from the latest firmware update to the C120 and C121 (F/W Versions: 1.3.1) for low framerate in the Tapo App, Poor Quality Connection/Stability via RTSP and ONVIF, and a quick update on improvements being made to Pet Detections.
Framerate Drops in the Tapo App
If you are currently experiencing difficulties with the live view or playback features of the Tapo App our team has released a test version of the Tapo app that should help address the choppy/low frame rate within the Tapo App.
RTSP and ONVIF
Our teams have investigated the cause of the c120 and C121 RTSP/ONVIF behavior and have prepared an early access firmware with a potential fix.
If you would like the development team to try and push the firmware to your device in advance, you can open a Support Ticket in our Systems on the Email Support Tab of our Support Page. Make Sure to Include:
-
- Subject: “C120/C121 ONVIF and RTSP After Recent Firmware Update”
- Ensure You Include Your Device’s MAC Address
- Include a Brief Description of the Behavior
- Include Your Current Hardware Version and Current Firmware Version
After updating your firmware, please let our teams know if this release resolved your behavior or if you are still experiencing difficulties.
Pet Detection Concerns
The team has followed up and they are actively testing and working to find improvements to the detections. If you have an additional example of missed or inaccurate pet detections, feel free to provide them so our teams can better understand what types of detections are met.

Both the App and Beta Firmware for the C120 and C121 are Beta/Early Access Releases and are considered at-your-own-risk. Their functionality cannot be guaranteed, and our community teams may not be able to provide direct support for apps or devices running this firmware. A formal fix for the behaviors will arrive in a future firmware update – so we only recommend updating to this version, if you have a need for the RTSP and ONVIF streams.

I see it today for my C120 as well. Upgrading now, will see how it impacts stability after a week or so.

It's late for me to update but the Tapo app is showing 1.3.2 is available for my C121. Support site for the C121 hasn't been updated to reflect this.

Also looking for when it will show up as an update on my C120. I am in Canada, is this only available in the US? I am finding the rtsp stream randomly goes nuts with Frigate causing a huge FPS and impact to the server.
would love to try 1.3.2 or go back to 1.2.3.

Just looking for an update on when this is going to be released for auto download to the cameras. It's now been nearly 2 months since it has been published in the release notes but is still not generally available
Thanks. Darryl

Interesting. I would've expected to see it pop up in the app if it's been a month since it was published. Guess it's just something we'll have it wait for since we can't just grab the file and load it manually.

The C120 has a new FW 1.3.2 dated at the end of June that may contain the test fixes?

Have you tried this yet?
Or are you like in my situation have the C121 and for whatever reason 1.3.2 isn't available for when I thought the internals are identical with a different color.

Hi @Solla-topee and @Riley_S , do have any update on this issue? Also it seems that the email tab is removed and it's not possible to send a support ticket to get the custom beta firmware.

Hi,
You can disconnect the RTSP stream with the third-party app, remove the RTSP entry, then re-establish the RTSP connection and check if you can stream the camera properly.
It's suggested to start a new thread here with the following information for further assistance.
1. Describe the detailed phenomenon you encountered after updating the firmware on the Tapo C325WB.
2. What third-party app is used to stream the camera?
3. Try a different third-party app, such as VLC and iSpy, and check if you can stream the camera properly.
