Cons: Requires subscription for cloud storage and smart features The Arlo Pro 4 is an elegant wireless security camera that's easy to set up and install. There's a choice of magnetic or screw-in mounts and a charging cable in the box. It connects directly to your Wi-Fi router, but that's the only thing that sets it apart from the excellent Arlo Pro 3, which connects to a SmartHub. Video footage is sharp and clear, with HDR ensuring that bright areas don't get blown out and darker areas retain detail. Color night vision and a spotlight ensure you don't miss anything at night. The two-way audio allows for easy conversation and there's a siren should you want to scare off any unwelcome visitors. The Arlo Pro 4 does the basics very well, and the app is easy to use. It connects swiftly and reliably and quickly recovers its connection after power or Wi-Fi outages.
