Our recommendation is to place the SmartHub in the best possible location – equidistant from the cameras, doorbell, lights etc. But you don’t necessarily want to run a long Ethernet cable to the router.

Instead, get a pair of NETGEAR Ethernet-over-Power – Powerline adaptors (about $199 for the pair). In fact, you can use more than two Powerline adaptors to distribute Ethernet ports around the house!

Now here is the conundrum about using a base station versus Wi-Fi attached cameras.

As you can now use the base station where it works best or add another (using Powerline to the router), you can now escape the typical 10-30 metre Wi-Fi 2.4Ghz range.

Just imagine – set up your old Arlo Pro 2 cameras outside the house connected to a nearby Pro base station, set up the 4K cameras where you need extra detail and the SmartHub where it offers maximum signal strength. Greater flexibility.

Rule One: A properly planned home Wi-Fi network pays huge dividends as you add more devices.

Now back to the Ultra SmartHub.

We have now solved the positioning dilemma – do not put it in a cupboard away from devices!!!

I can see the logic in keeping the Arlo devices off the main home Wi-Fi network only talking to the SmartHub. The only time the SmartHub accesses the Internet is to upload events (in 1K resolution or less) to the Arlo cloud, so you can remotely view them. Or you can just set it to record locally to a microSD card, but you must remove the card to view on a PC.

There is little to say about the hub – an Ethernet port, a LED to indicate its state, a reset pinhole and a sync button (for older Arlo products). But it hides a lot more inside. Apart from its SmartHub IoT potential (Works With Arlo mentioned earlier), it does much of the cameras work and helps manage power use.

So, I am now more convinced – no more video and audio traffic overwhelming my other IoT devices on the smart home network.

Voice Assistance

I added Arlo to Google Home, and it found all devices apart from the Doorbell and chime. That is no big deal, and I will get to the bottom of that later. Google Home allows you to view each camera or device but not make granular setting changes. It can also cast the camera image to a TV or smart screen.

Arlo Ultra Voice

There is a very small range of voice commands. “OK Google show FrontDoor on Sony”. I am sure that we will discover more things like Google’s geofencing or IFTTT (If this then do that), but that is for another day.

Camera VMC5040

Arlo is chuffed at the 4K camera – 1K (1080) or 720 or 480p is so yesterday. It says, “See your recordings in super sharp, 4K HDR detail.” So, we dug a little further and its pretty good.

These are good specs but do not really tell you how it works.

Two Ultra cameras (max) can simultaneously stream 4K to the SmartHub. If you enable things like auto-zoom or auto-tracking, it drops to 1K or lower. You can connect the cameras to the older Pro Base Station, but you only get 1K video at best. And you can only stream 4K to your smartphone on the local network – not remotely from the cloud – or the microSD card unless you pay for a PVR cloud upgrade.

Power management options are best video, optimised, or best battery. That leaves the resolution at 4K but changes the bit rate. A lower bit rate means a lower quality image.

Lowlight settings include colour/mono (bandwidth changes), night vision and brightness. And we love the software settable field of view.
