The Arlo Pro 4 is a high-end wireless smart home outdoor security camera which fits into a large and growing range from Arlo which includes hubs and doorbell cameras and competes comfortably with the likes of Google’s Nest and Amazon’s Ring cameras. With 2K HDR this camera sits in the middle of Arlo’s outdoor range – beneath a 4K option and above the ‘Essential.’ It’s predecessor (still available) offered the same strong image quality, but the Pro 4 brings a built-in siren and full duplex speaker – making it handy for frightening off unwelcome visitors rather than mere forensics. Perhaps more significantly, it has dispensed with the requirement of a base station.

If you’re looking at your first security camera, it’s worth noting that the Arlo is part of an elegantly designed and consistent-looking range of devices including Hubs, Doorbells, Floodlight Cameras and even the LTE Arlo Go. They have been around long enough to build up a range of accessories, from camera camouflage to solar panels, and the fact there is now no need for a hub – but the option exists – gives you more feature and budget flexibility.
