When considering security cameras, it is best to opt for cable (with PoE, Ideal), you can look for:
Avigilon
NVR: PRO 16-PORT (Includes switch with 16 PoE ports)
Cameras: H5A or H4ES
If you are looking for something cheap
Hikvision / Epcom
NVR: XR416 (US) (Includes switch with 16 PoE ports)
Cameras: XB-26ZH-US or XT-26ZH-US

Seriously, it is a shame to know about this, I use it for some computers with Windows and Android and iOS for my family.

Is there an option to protect Android and iOS devices or is it unnecessary?

Bitdefender can be an option, includes a cloud management console or can be on-premises.
If my memory does not fail it has support for windows, macos, linux and android and ios mobile devices.
