C110 Low Quality Video
C110 Low Quality Video
Hi everyone,
Can anyone please help me? I've recently added a C110 to my group of C100 Tapo cameras, and the video quality is very low compared to the C100's. The C100's are HD (1920x1080) and the C110 is 2K. A C100 in the same room has much a much better image quality than the C110. The quality is low when recording to an SD card as well in the app, so I believe it is either a faulty camera or a setting issue.
Has anyone got any ideas?
Many thanks.

@Solla-topee Hi again,
I've discovered the problem. I managed to get a recording from a C100 running at 1920x1080p, and another from the C110 running at 2K.
I've pasted the mediainfo below. As you can see, the problem is the compression; the C100 has an overall bitrate of almost double the bitrate of the C110, even though it should have a higher bitrate to maintain the same quality as it's a higher resolution. The C100 is on the left, and the C110 is on the right.
Can you please tell me how to change in the bitrate on the C110 SD card recordings? I can't see any option anywhere.
Thanks

Hi,
The Tapo cameras do not support changing the bit rate. This comparison result is not accurate for the following reasons:
1. Tapo Camera uses a Variable Bit Rate mode, its bit rate will change according to the complexity of the monitoring scene and whether the monitoring content is static or dynamic. Generally, the more complex the monitoring scene is, and the more motion occurs in the monitoring scene, the higher the bit rate will be.
2. The duration of the two compared videos is different, and the scenes may also be different. The duration of the C110 video is almost twice that of the C100.
To confirm if the Tapo C110 has an issue, you can provide the cameras' video recordings for analysis when the two cameras are in the same position, monitor the same scene, and are set to the highest video quality.
You can upload the videos to your cloud server(such as Google Drive), generate a link to download them, and then send me the link via a private message.
Best Regards

@Byrd1 I presume you've gone into the settings (via the app) for the camera and selected 2K as the resolution? When I got the C210 I found it defaulted to 1080p & had to specifically choose 2K.

Hi,
In addition to checking the video quality settings on the camera's Device Settings > Video & Display > Video Quality page, please also confirm how many devices are viewing the C110 at the same time. If multiple devices are viewing at the same time, some devices may use low resolution. In this case, you can try restarting the camera C110 and viewing the camera on only one device.

@MattC_UK yes, I thought it would probably be that simple too, but it was set to 2K. I tried charging the resolution but the quality is the same on any setting (just a higher resolution, so the squares are bigger!). The quality is the same on the SD card recordings, so I don't think it's a WiFi issue. A C100 running at 720p is roughly twice as good quality when I put it next to it.
Any other ideas? I think I probably just have to send it back and swap it for another.
Thanks

Hi,
You can try the suggestion here. If the problem remains and you are willing to continue to troubleshoot, please put the Tapo C100 and C110 in the same place > set them to use the highest resolution > capture the picture on the camera's live view page > send me the pictures to have a check.
Best Regards

@Solla-topee Hi, thanks for the reply. I've only got the app one one phone so there can only ever be one device watching. The video quality setting is set to 2K. The SD card recordings are also the same very low quality, so I don't think it's an issue with WiFi. Thanks.

@Solla-topee Thanks, I've moved the HD cameras now but I'll try and move one back and do a screenshot, but as I said, the SD recordings are the same low quality so I don't think it's related to the quality of the network. I feel like it's some sort of video compression that has been activated (or the lens on the C110 is much worse than the C100, or the one I have is broken). I'll try and post back asap. Thanks.

@Solla-topee Hi again. I've attached a couple of tests. The first is the C110 (Hardware version 2.0) running at 2K (2304x1296) and the second is the C100 (hardware v4.0) at 1080p (so I suppose 1920x1080).
In both cases, I've zoomed in as far as possible to see a piece of paper with some writing and boxes on. As you can see, the C100 is much clearer and defined.
Thanks.

@Solla-topee Hi again, just wondered if you'd had time to look at the images? Thanks.

Hi,
Thank you for your cooperation and testing, but such a comparison is hard to identify that there is a problem with Tapo C110. It is recommended to place C110 and C100 in the same position, monitor the same scene, without zooming in the lens, and then take a screenshot of the camera's live view page and share it here.
Best Regards

@Solla-topee Hi, thanks for the reply. Are you sure that's needed? The zoomed-in images I have shown show the difference in quality much more than a zoomed-out shot will.
I just want to know if there's a way to control the quality of the recording (other than the resolution), which I suppose is the video compression. If there is no way to do that, then either the C110 I have is broken, or it has a lower-quality lens than the C100, or the compression is set much higher. I suspect that it's the latter, and the programmers have compressed the video to the point where it isn't usuable.
Thanks.
