Why set up an Arlo home? (includes Arlo Pro 3 camera mini-review).
4.6Overall Score
Name: Arlo Pro 3
Price (RRP): $419 single camera
Manufacturer: Arlo

Over the last two years, we have tested a lot of excellent Wi-Fi-based security systems. But our conclusion is that, while expensive and with ongoing subscriptions, an Arlo home works best.

Why an Arlo home? Well because it is a fundamentally different system to Wi-Fi-based security cameras, doorbells/chimes, security lights and more.

An Arlo home is one of the most complete ecosystems, and there is one little secret to its success – it works first time, every time. Why?

Arlo Home

Enter the Arlo home hub – the secret sauce (Arlo calls it a Base Station).

At the core of every Arlo home system is a hub – it can be one of three types or multiple hubs placed for best efficiency.

Depending on the model, the hub serves several purposes.

First, it communicates with Arlo devices using its own radiofrequency. That means all the traffic is kept off the Wi-Fi home network.  I repeat no traffic at all over Wi-Fi and not subject to its vagaries, dropouts, slowness and congestion.

Second, few Wi-Fi routers have the power or reach to stream video or reasonably lag-free two-way conversation. For example, if you are streaming video or music, there may be little Wi-Fi bandwidth available for others to use. That is why so few Wi-Fi security cameras can live stream above 720p and often at 10-15 frames a second.

Third, the hub communicates with the router via an Ethernet cable at speeds typically of 1Gbps (125MBps).

Fourth, the hub compresses security camera video into H.264, or H.265 (much smaller) streams so that smaller signal goes straight through the router via its internet connection to the Arlo cloud where it is stored for a time depending on your needs and the appropriate cost.

Some hubs have USB or micro-SD local storage, especially useful if the internet is down, sirens etc

In summary, we have found the hub maintains a rock-solid link to Arlo devices, it does not suffer from the vagaries and unreliability of Wi-Fi and internet and is always available for remote viewing (if the internet is up).

Different hubs

You don’t go and buy a hub then buy cameras (although you can). Arlo works on supplying the right hub in starter packs with cameras – these are more economical.

While the hubs are backwards camera compatible, e.g. an Ultra Base Station can run Arlo Pro (720), Pro 2 (1080), Pro 3  (2K) and Ultra (4K) but a Pro base station can only run cameras at 720p – they are not so much forward compatible.

Our best advice is to start with the Ultra hub and attach a mix of Pro 2, Pro 3 and Ultra cameras according to need.

As you can see, the subtle differences are in resolution (1080 vs 2K vs 4K), mics (single/dual) and a slightly wider Field-of-View. But the Pro 2 is older technology, and a lot of its features are only available when using the power source or via the cloud.
