I need 4 cameras (TC70, C 200 - actually the same) to ensure the necessary surveillance.

I am supposed to pay 12 euros a month for this, it used to be 37 euros before.

Other companies provide a free cloud in the same price range.

Without the cloud, the camera is useless.

Moreover, I don't want from a company I don't know like tapo being forced to be spied on. 

<b>Is there any possibility to use my own cloud which is much cheaper, more reliable and more trustworthy?</b>

I think it was a big mistake to buy these 4 cameras because of the limited possibilities for cloud storage.
