Arlo Ultra 4K Camera Review

Promised Features

Arlo Ultra 4K Camera Features Breakdown

If the Arlo Ultra website didn’t make you excited, then I guess you’re not as much of a security geek as I am. The website promised that the Ultra has:

• 4k video display: yes, you read that right. The Ultra apparently goes above and beyond the industry standard of 1080p HD.
• Two-way audio: always a favorite of top security cameras.
• Indoor/ outdoor capabilities: I love that the Ultra works inside and outside.

Given the camera’s name, its main draw is its 4K video display. Along with that, the camera has the following features.

HDR

In a nutshell, HDR, or high dynamic range imaging, creates images that look more like what you actually see. It’s great for areas with direct sunlight or extreme shade, relevant as the Arlo Ultra works outside.

I’ve tested a number of HDR cameras before, such as the Nest Cam (battery), but Arlo Ultra is so far the only 4K camera I’ve had my hands on that offers HDR. The Nest Cam’s video resolution is only 1080p, but the HDR contributed to make the images life-like. See it in action in my Nest Cam (battery) review. With the 4K-capable Arlo Ultra, videos were almost cinematic thanks to HDR.

Dewarping

Arlo Ultra has a 180-degree viewing angle. If you’ve been testing security cameras as long as I have, you know what that could mean: Warped videos. Even a screen with a 16:4 aspect ratio won’t be able to show an entire 180-degree frame, so most cameras with a 180-degree viewing angle have a fish-eye lens effect. I say “most” because there are some cameras like the Arlo Ultra that use dewarping to normalize how videos are shown on a screen. There was still a little distortion, but it wasn’t bothering.

Panoramic Simulation

Did I mention that the Arlo Ultra has a 180-degree field of view diagonally? That’ll enable you to see more of your property, which is clearly the goal if we’re looking for a security camera. Plus, that means you won’t need to buy multiple cameras for wide open areas like your front yard. That’s a decent perk, considering the camera’s premium price point.

Necessary Features

I truly don’t know where I’d be without our Necessary Features Test. It’s my compass that tells a bad camera apart from a good camera apart from an amazing camera. Let’s see if the Arlo Ultra has what it takes to pass our test.

Video

The Arlo Ultra’s video quality is what makes it stand out from the majority of security cameras currently on the market. Typically, the standard video display of a home security camera is 1080p HD. 4K resolution, on the other hand, can appear twice as clear as 1080p HD.

Unfortunately, the Arlo Ultra 4K can’t actually shoot in 4K without a subscription. Initially, I was baffled. How can a camera that has 4K in its name only stream in 1080p HD? I checked myself multiple times and tried to upgrade, but the hard truth is that the Arlo 4K can’t actually produce what it says it can out of the box. To get 4K cloud recording, you’ll need to subscribe to an Arlo Secure Plus plan. The added cost is frustrating considering 4K is part of the product’s name.

Despite this, I am happy with the camera’s 1080p HD video display, so full marks for video.

Night Vision

The Arlo Ultra is pretty unique when it comes to night vision. It has two LED sensors that produce infrared light, allowing the camera to see in the dark and produce black and white footage.

However, the camera also has color night vision from its motion-activated spotlight. As you can see, both of the night vision video displays are pretty clear, so I’m happy with the night vision.

Audio Quality

Of course, the Arlo Ultra comes with two-way audio which allows you to talk with whoever you’re recording. I believe every security camera should include two-way audio, as it’s super useful for scaring away intruders. Full marks for audio!

Storage

With a security camera, you want to make sure you have a way to back up your footage. Actually, you really should have two ways of backing up your footage in case one of them fails. Luckily, Arlo offers both cloud and local storage in the Arlo Smart plans. The Arlo hub has a port for a micro-SD card for local storage, but as far as cloud storage goes, you’re going to need to invest in a paid plan. Still, the camera gets full marks for having both types of storage available.

Smart Platform Integration

As you can see on the box above, the Arlo Ultra integrates with both Amazon Alexa and Google Assistant so you’ll be able to use voice commands to control it.

Artificial Intelligence

Here’s some good news: your purchase of the Arlo Ultra comes with a free trial of Arlo Secure, so you can put the smart features through their paces before committing to a subscription. So what exactly does that give you? For starters, A.I.

With Arlo Secure, your Ultra will give you person detection, pet detection, package detection, and even vehicle detection. Being able to tell the difference between moving images is going to give you more specific notifications. Plus, the Ultra offers auto zooming and tracking so it can focus on what’s important— people moving in front of it. For these awesome features included, I’m giving the Arlo Ultra 4K full marks when it comes to artificial intelligence.

Convenience

When it comes to installation, the Arlo Ultra 4K was quite simple. All I had to do was download the app, set up the Arlo hub, put a battery in the camera, and I was good to go in under 15 minutes.

But convenience isn’t all about installation. It’s also about how easy the camera is to use. And for that, the Arlo Ultra lost major points.

First of all, the Ultra has an incredibly short battery life. It lost about 25% of its life in a single day. For a wireless camera, you can see how this could get tiresome. You would literally need to change the battery every four days, which doesn’t exactly scream convenience.

Next were the connectivity issues. It was really hard to livestream footage from the Arlo Ultra 4K camera onto the Arlo app. Now, this may have had something to do with my Wi-Fi, but in comparison to other cameras, there were way more connectivity issues than normal. Livestreaming was a struggle, and I spent a lot of time trying to connect. For these reasons, I have to give the Arlo Ultra 4K half marks for convenience.

Value

At $400, the Arlo Ultra 4K camera is the most expensive camera I’ve ever reviewed, and the fact that it doesn’t actually produce 4K footage makes the price even more ridiculous. Unfortunately, I can’t recommend that you buy this camera until it’s updated significantly. No marks for value, unless you get a great Prime Day discount on Arlo cameras or a Black Friday discount on Arlo cameras.

Extras

I want to talk about three more features of Arlo Smart Home that don’t fit so neatly into categories.

Lock Screen Notifications

With any of the Arlo Smart Home plans, you’ll receive lock screen notifications in the form of a screenshot from the livestream. This makes it easier to see what’s happening at home without even having to open your phone.

e911 Emergency Call Service

Arlo’s Smart Premier and Smart Elite plans give you an in-app button that’ll automatically call 911. Pretty useful, although I hope you’ll never need to use it.

Custom Activity Zones

Finally, all of the Arlo Smart Home plans give you custom activity zones. Basically, you can go into the Arlo app and tell it to focus on specific areas, like a window or a baby’s crib. This will also help make your notifications more specific, as your camera can tell you exactly where motion is happening.

Video Review

Mobile Application

You’ll control your fancy new Arlo Ultra through the Arlo app. Here, you’ll be able to livestream footage, control device settings, talk through two-way audio, connect to smart home platforms, receive notifications, and view cloud storage. The app has decent ratings of 3.9 and four on the Apple and Google Play stores, respectively. Unfortunately, as I said before, there’s a delay between the camera and the app’s livestream. Clearly, this is a huge issue if you do have an intrusion. However, since the app’s ratings are generally positive, I feel comfortable saying that the app itself is useful.

Comparisons

So clearly the Arlo Ultra 4K is not what I had hoped for, but I still want to show you how it compares to similar cameras. I chose the Arlo Pro 2, a sister camera, and the Nest Outdoor.

Arlo Pro 2

The Arlo Pro 2 is Arlo’s previous iteration of an indoor/ outdoor camera. Like the Arlo 4K as we learned, the Arlo Pro 2 has 1080p HD video display, the industry standard. Its field of view is 50 degrees more narrow than the Ultra’s at 130, which is still pretty wide. Both of the cameras offer two-way audio plus integrations with Google Assistant, Apple HomeKit and Amazon Alexa.

Unlike the Ultra, the Arlo Pro 2 does not come with Arlo Smart Home, so you’ll need to purchase person detection, pet detection, and other useful features. The Arlo Pro 2’s big advantage over the Arlo Ultra 4K, besides being true to its advertisement, are its lack of battery and connectivity issues. It also comes with a week of cloud storage on the house, which the Ultra lacks. Overall, I would definitely buy the Arlo Pro 2 over the Arlo Ultra 4K. It’s only $220, compared to the $400 I paid for the Arlo Ultra 4K.

Nest Cam Outdoor

The Nest Cam Outdoor costs half as much as the Arlo Ultra 4K at a cool $200, still on the higher-end for home security cameras. Like the Ultra, it records in 1080p HD, with a field of view 50 degrees narrower than the Ultra at 130 degrees, just like the Arlo Pro 2! Both of the cameras have great infrared night vision, two-way audio, and integrations with Google Assistant and Amazon Alexa. Unfortunately, the Nest Outdoor has no local storage and only three free hours of cloud storage. You can buy five days, 10 days or a month of cloud storage, but it’s going to be a bit pricey, even pricier than Arlo’s cloud storage options.

While the Nest Outdoor doesn’t include any A.I capabilities, you can purchase person detection and activity zones with Nest Aware. The Arlo Ultra 4K comes with person detection and activity zones, so it has the Nest Outdoor beat in this category.

Again, the Nest Outdoor works as advertised. It records in 1080p HD, has a normal battery life and no serious connectivity issues. Plus it’s half the cost of the Ultra, so I’d buy the Nest Outdoor over the Arlo Ultra 4K camera any day of the week. For more information, read my full review of the Nest Cam Outdoor.
