Arlo Ultra 2 – 2021 update to the world’s best 4K security camera

Arlo Ultra 2

The Arlo Ultra 2 has taken a perfectly good Arlo Ultra 4K camera and tweaked a few things to make the perfect 4K security camera even better.

The main difference is the Arlo Ultra 2 adds Wi-Fi 5Ghz (you many need a new SmartHub to use this*) and increased 2.4Ghz range. Otherwise, it’s the 4K, HDR, 16:9, 180° FOV, spotlight, that made it the top 4K security camera last year.

Arlo Ultra 2 models include

  • Camera only (VMC5040-200AUS) $449
  • 2 camera and VMB5000 SmartHub (VMC5240-200AUS) $1099
  • 3 camera and hub (VMS5340-100AUS) $1449

If you are an existing Arlo user

The 2020 Ultra 4K comes with the same VMB5000 SmartHub. The faster 5Ghz channel cuts in if the signal strength is sufficient. It also uses micro-SD cards for local recording.

If you have a VMB4540 SmartHub that came with the Pro 3, then the maximum recording resolution is 4K, and it only uses the 2.4Ghz Wi-Fi channel. This uses a USB-A slot for local recording.

Earlier VMB4000 or 4500 SmartHubs will also support the Ultra 2, and 4K provided the hub has sufficient bandwidth for existing cameras.

GadgetGuy’s take

It is hard to improve on perfection.

The Arlo Ultra (review here) is everything you can expect from the Ultra 2. It scored 4.4/5 – the highest of any wireless security camera to date.

At that time, we were betwixt and between whether a camera needs a SmartHub or if Wi-Fi is adequate, And being typical Aussies, we were still smarting the Smart Subscription cost.

The SmartHub adds incredible reliability, range and local storage to Wi-Fi-based devices. Over the past year 18 months, the Ultra has had 100% uptime, even when the internet is down (looking at you Telstra but is now vastly better since the switch to Aussie Broadband).

We now understand that the Smart Subscription is worth every penny for the advanced cloud features it adds. Customisable zones, object detection, etc., all need cloud AI to function.

Finally, Arlo’s solar panels are a blessing having topped up cameras each day regardless of rain, hail or shine – not one manual recharge in 18 months.
