You should ask this question directly to Galaxus Support rather than here in the Community

No, you do not need to order a memory card for the Tapo C520WS camera. The camera supports both recording on a MicroSD card (up to 512 GB) and the use of Tapo Care cloud services. The MicroSD card can be purchased separately and inserted into the camera if local storage is preferred.

Works flawlessly with the Surveillance Station package in the Synology NAS, also mobile with the DS Cam app. Does not require a memory card or registration with the Tapo Cloud.

The camera can rotate 360 degrees and can be connected to a solar panel as it is powered by trafo

This camera cannot be connected to a Tapo solar panel. It has no internal battery and requires a direct mains supply, making it incompatible with the Tapo A201 solar panel designed for rechargeable battery cameras. It is not recommended to adapt this camera to a solar panel via a converter, as this could adversely affect its performance and safety.

I have two C520WS. Both were supplied with a power supply unit.

No solar panel was included in my delivery. It was also not included in the scope of delivery. I don't know whether it is available as a separate accessory.

If it is powered with the identical values as the supplied power supply (Output 9.0V DC 0.85A 7.65W) there should be no problem

The audible alarm can be switched on and off in the device settings of the Tapo app. To do this, go to the "Device settings" page and search for the alarm menu to adjust the settings accordingly.

Thank you very much!

I currently have 4 Tapo cameras in the same app, unfortunately I don't know the maximum number that will work. Slide cameras can be operated with or without a plan. Without a plan, one memory card per camera is required; when this is full, the oldest recordings are overwritten.

The camera can also be used in a garage as it is designed for outdoor use and is robust enough to work in a variety of environments. When it is pitch dark, the camera offers a night vision function with Starlight Color Night Vision, which provides better colour images even in low light. This function makes it possible to see even in dark areas.

According to our information, this is unfortunately not possible.

The appliance is operated with a 240V power connection. If a solar system can operate this power connection, I don't see any obstacles apart from the fact that the sun doesn't shine all the time. For example, we run our entire electricity needs with photovoltaics

Yes

Hi, the app is only available for smartphones/tablets. You can have limited access to it via a NAS. Goggle/KI will help you with the search/setup

My camera detects movements, e.g. of cars, even at a distance of about 80 metres. I haven't tested it any further yet

I am very happy with the results of the camera, I have several Tapo cameras and the C520 was my favourite because of its good video quality and ease of use

Works with CH sockets

Yes, the Tapo C520WS camera allows you to view live images directly without the need for a pulse from the motion detector. You can view the camera live at any time via the Tapo app without the need for recording. The camera offers permanent live transmission in 2K QHD resolution (2560 × 1440 pixels) so that you can have an up-to-date view of the monitored area at all times, even if no movement is detected.

It can use RTSP to connect to a NAS if that's what you mean. It also has it's own "cloud" but that is probably not what you want.

Control and image information from the Tapo C520WS camera can be accessed via various platforms, not just a mobile phone. - Mobile app: The camera can be controlled via the Tapo app on your smartphone or tablet. This app allows live view, playback, saving clips and setting up the camera. - Laptop/computer: There is no specific desktop app, but you can control the camera via the web browser on your laptop or computer by visiting the manufacturer's website and logging in. - Voice Assistants: The camera is also compatible with Amazon Alexa and Google Assistant, allowing control via voice commands. This means that control and image information is not limited to mobile phones, but can also be provided via other devices and platforms.

With two cameras, you have a good starting position. The camera is defective and should be returned to the store.

Yes

Hello, no, the camera does not support this. You must use the mains adapter supplied. See: https://www.tapo.com/de/faq/66/ - Question 5.11
