Camera Goes Off Line

As per title.

We have a 4 camera (plus door bell) system.

One camera has started going off line. It comes back on line without intervention. Battery is near full charge (365 day cameras installed within last few weeks).

It is located close ( within 50 cm) to another camera which is fine (corner location).

Also a question:

Do the cameras use my Wi-Fi network or do they communicate with the base unit direct?

Regards

Brian
