Timeline and Recording Issues with H200 Hub SD Recording (C510W & C520WS)
Since switching to SD card recording through the H200 hubs, both my C510W and C520WS cameras have had problems. Each camera is on its own dedicated H200, both using Ethernet. None of this happened when the SD cards were in the cameras directly.
Motion is often flagged when nothing happens, or a short event gets stretched into a 2–3 minute clip. Sometimes I just get one frame from a few seconds in, then it jumps ahead and skips the rest. In continuous mode, there are gaps where it doesn’t record anything. Right after those gaps, it usually shows a motion alert even though there was no motion.
The timeline is much faster to access now and downloads are quicker, but the footage itself is unreliable.
I’ve tried lowering FPS, reformatting SD cards, using endurance cards, rebooting everything, removing and re-adding hubs, and making sure the network is stable. Nothing has fixed it.
I’ve also had a separate issue on one camera where it just stops recording until I reboot it or reformat the SD card, but that’s not part of the timeline bug.
Anyone else had these problems with hub recording?

The discussed situation in this thread may arise from the stability of the device connection. Unstable network connection could interrupt the video transmission from the camera to the hub. Depending on the camera model and the configuration, there are three connectivity points to check: from the camera to the hub, from the hub to the router, and from the camera to the router.
The following provides corresponding troubleshooting suggestions based on the current camera settings.
Case One: Camera Not Using Tapo Hub as a WiFi Backup
Try connecting the Tapo hub to the router via Ethernet and monitor whether the camera continues to record the same types of videos.
If the same situation persists, then the problem is likely related to the connectivity between the router and the camera. In this case, you will need to check the camera's signal strength. How to check and improve the network connection stability of Tapo smart devices
*As the signal strength may fluctuate, we recommend checking this several times at different intervals to ensure accuracy, especially if you notice longer loading times during operation.
Case Two: Camera Use Tapo Hub as a WiFi Backup
Confirm camera's current network source: go to camera Device Settings page, click Network Connection, check what is displayed in the Current Network: WiFi (router), Ethernet (router), or Hub?
On the product settings page, in the Network Connection section, clicking the WiFi icon on the right shows the camera's current signal strength (RSSI value). How to check and improve the network connection stability of Tapo smart devices
| Signal Strength Value Reference | |
|---|---|
| Strong | more than -50 dBm |
| Good | among -70 dBm to -50 dBm |
| Poor | less than -70 dBm |
- If the camera is currently connected to the router (whether it is through WiFi or ethernet), please refer to the suggestions mentioned in Case One.
- If the camera is connected to the hub, compare the video quality recorded by the camera under different connection methods -- Tapo hub's connection: wired vs. wireless.
- If the hub has been using a wired connection, switch it to WiFi and place it midway between the router and the camera. Monitor for new changes on the recorded video afterwards.
- If the hub has been using a wireless connection, switch it to a wired connection and Monitor for new changes on the recorded video afterwards.

I don't think the false detection issue is relevant to the hub storage feature. What's the detection sensitivity of your camera? If the detection sensitivity is set too high, false alarms can easily occur. For example, there may appear to be no activity in the footage, yet motion detection is triggered.

Hi @Wayne-TP,
Which is the responsible device for detection of person/movement etc in that case when the H200 HUB is the target of recordings?
I also found differences since my HUB was set to be storage of my cameras - already described in another thread.
And I can say that the recorded clips are shorter than the camera created onto it's dedicated memory card in case of similar scenes.
I'm just guessing without knowing the background of the solution exactly, and think that the HUB check the streams and detects what happens then starts recordings in case of any specified trigger event.
Maybe this is why we can see results different than that when the camera itself does the same - detects and save footages.
Thank you.

I didn't have false detections before the change over to the hubs. My sensitivity is at 8 for motion and I set it as such as i was getting missed detections on lower sensitivities.

yeah it's buggy when you keep records on the hub, missing detection event, I'm in contact with support about it and my cam

Hi @SugarBaby,
I still monitor how the HUB storage works and found that even we continously there in the C520WS camera's FOV, the recording stopped multiple times.
So, not all the scenes were recorded and I cannot fully play back what happened in that particular period of time...
I don't know if you meant the same when mentioned missing detection event in your previous reply.
Thank you.

Hi @Wayne-TP,
No, I didn't report missing detections to local TP-Link support. There was no problem with the WiFi connection at that time I found the recording/detection issue mentioned previously.
In general, I found that performance and accuracy of HUB recording are lower than if cameras record onto their dedicated SD card...
Hub recording:
1. generates shorter clips - less seconds before and after the event.
2. since the mentioned occurrence, I found missing scenes and didn't understand why the hub stopped recording even if I was there in the cameras FOV.
3. Unexpected No recording messages
4. choppy playback
Points #3 and #4 have already been raised.
Thanks

@Wayne-TP Thanks for the suggestions, but I don’t think they apply to my issues/case
Both of my H200 hubs are connected via Ethernet, as is one of the cameras.
I provided logs, videos of the issue and my overall set up to TP-Link dupport and they are looking into the issue further.
Given that TP link support went through troubleshooting steps with me, looked at my recorded videos of the issue and couldn't find much it seemed so it seems like it's a bug.

The phenomenon #1 is actually the feature design when the camera is set to save video to the hub. The video ends sooner when there are no more movements. The record buffer will be longer if the videos are saved to camera's own sd card.
As for other situations, a targeted individual analysis is necessary to determine the specifics. Provide relevant information to technical team based on each scenario, such as screenshots or videos, to facilitate a more thorough investigation.
