ARLO Pro 2 vs. ARLO Q ro ARLO Q Plus

[Jul-Z]

What is the benefit of purchasing 4 ARLO Pro 2 and then adding either more ARLO Pro 2 or ARLO Q / Q Plus? 

I have read the descriptions and see the ARLO Q/Q Plus are powered and the Pro 2 are rechargable battery life.  For the Pro 2 it lists a power adaptor and cable is that for the base station only?

Additional cameras are just for your benefit if you need more coverage. The Qs are for indoors only while the wireless cameras are indoor/outdoor.

There's a power supply for the base but there's also a USB charger (Qualcomm Quick Charge-capable) for the cameras. They're not interchangeable.
