Questions about Reolink RLC-410W 4MP Bullet IP Camera

Why is the price of this camera somehow raised from 88 to 94 and a few days later advertised with a generous 13% discount? As a customer, I feel a bit deceived. It would be more honest to just offer a discount of 6 or 7%, which doesn't look like much, but is much more customer-friendly. =(

Is this camera (plug and play) or do I need to buy some kind of base station? Does this device also record sound and can I communicate via the camera (with the children or similar)?

Does anyone know a way to hide the Reolink logo at the top left of the stream?

Does anyone know if the camera can also be operated without a network connection or does anyone know of an alternative product? Thanks in advance.

In the event of a motion alarm, are the photos sent automatically by email immediately and while the motion is still ongoing? Is the 30-second video clip automatically sent by email immediately after recording? Can pictures / video clip be sent to different email addresses?

does anyone know why it does not recognise my memory card? is it too big GB?

Are Micro SD cards included in the scope of delivery?

Does the camera only have PoE power? On the Reolink website, the scope of delivery includes a power adapter and a 4.5 metre extension.

Can this camera also be used without a Wi-Fi connection? Or will the data still be saved on the micro SD card without a Wi-Fi connection?
