Question about Arlo Pro 2 – set of 5

Hello, yes but be careful, the product will no longer be waterproof, so this works for indoors. it is true that the batteries are a bit weak, but the kit is still great

Yes, the cameras have a micro USB plug for charging, you can leave them plugged in if you want. However, you need to bring extra cables and chargers if you want to. Otherwise, the battery lasts long enough.
I have this kit and I think it's really great. Greetings
