Arlo Pro 4
Each Arlo Pro camera generation has been better the last, but it was hard to imagine how the Arlo Pro 3 could be improved. The folks at Arlo must have felt the same because they barely made any changes for this fourth-generation device, the Arlo Pro 4.
There is one big change, though: You no longer also need the Arlo SmartHub base station, which has been a staple component of every Arlo Pro camera going back to the product’s introduction. While you
can use the Arlo Pro 4 with a SmartHub if you have one, it’s not strictly necessary to get a wireless signal sufficiently strong to deploy this indoor/outdoor camera outside. And that’s no small improvement.
