Arlo Pro 4 Smart Camera Review.

The Arlo brand entered the home security camera market in 2014. It has since launched a wide variety of WiFi-connected cameras every year, leading to an extensive line of products. In fact, some of its models are among the best on the market.

Arlo has improved the resolution in each iteration and added useful features that reduce unwanted alerts, making each camera feel like a huge improvement over its predecessor, and ensuring that they make our top 10 list of home security cameras. Despite this, Arlo Pro 4’s latest release proves the opposite to be true. According to the Arlo Pro 4, the Arlo Pro 4 is an incremental update. In fact, many of its features – including the resolution and the AI functionality – are already available on the Arlo Pro 3.

Despite some changes, Arlo Pro 4 can connect directly to your home Wi-Fi network, such as Arlo’s Essential range of more affordable cameras. As a result, the camera is cheaper at $199.99 / £220 / AU$290 since it doesn’t require a SmartHub.

Because a built-in spotlight illuminates the camera at night, Arlo Pro 4 records 2K resolution color footage during the daytime as well. With a 160-degree field of vision, the camera will alert you via your smartphone if it detects motion, so you can view the camera’s feed in real-time. Arlo Smart also stores the video clips in a secure online area, and the clips can be viewed at any time for 30 days after being recorded (if you subscribe to a Smart plan).

There’s no local storage option with the Arlo Pro 4, as it doesn’t include SmartHub. Not only that, but it’s free for three months. In this case, you will be required to continue to pay $2.99 / £2.49 / AU$4.49 per month if you would like to watch videos after they have been stored.

However, Arlo Smart offers much more than just online storage for video clips. In addition, it provides several AI-based features designed to reduce unwanted alerts, such as the ability to differentiate whether motion is being caused by a person, animal, vehicle, or another source, and the ability to create zones so notifications are only pushed when activity is detected within those areas.

It features weatherproofing and a rechargeable battery that can last up to six months, similar to other Arlo home security cameras. It’s also compatible with Alexa and Google Assistant, but to use HomeKit, you’ll have to purchase a SmartHub for $99.99 / £179 / AU$290.

Although it’s less expensive than Arlo Ultra and Pro models, it’s still one of the more expensive security cameras available today. The Arlo Pro 2 cameras, which only record video in Full HD, are still worth investing in if you’re looking for a camera with detailed recording without needing a base station.

Arlo Pro 4 Smart Camera: Design

Arlo pro 4

  • Battery-powered or hard-wired
  • Weatherproof
  • Directly connects to your Wi-Fi network

Arlo Pro 4 shares the same design as the Arlo Pro 3 and Arlo’s other home security cameras, consisting of a glossy white plastic body that can be removed in one piece, along with a black front housing the 160-degree camera lens and LED spotlight. You can remove the Arlo Pro 4 battery by pressing the button below the connector pins for the magnetic charging cable (for hardwiring). It measures 3.5 by 2 by 3 inches / 8.9 by 5.2 by 7.8cm (h x w x d).

It comes with a magnetic stand that can either be mounted to a wall or free-standing. The Arlo Pro 3 can be used in all kinds of weather conditions. Due to the fact that this mount can easily be detached from the camera, an optional screw mount is included for this purpose. You’ll need to purchase an optional mount separately; it will cost you $19.99 / £12.99 / $39.99.

With the Arlo Pro 4, you no longer need a SmartHub since it connects directly to the Internet. It was actually very simple to set up the Arlo Pro 4. As outlined in the Arlo app, we simply entered the Wi-Fi password, scanned a QR code, and updated the firmware for our camera using the instructions.

Arlo Pro 4 Smart Camera: Performance

Arlo pro 4 review

  • The color footage is clear and detailed in the daytime as well as at night
  • 160-degree field of view has a slight fisheye effect
  • Motion tracking and automatic zooming

In our testing, we found the footage recorded by the Arlo Pro 4 to be clear and detailed, and the 12x zoom allowed us to focus on small details. We recorded the footage in color both during the day and at night, provided the spotlight was triggered in low-light conditions when motion was detected.

Even with the 160-degree field of view and HDR support, we could still see minute details even when the sun was shining brightly or dark shadows were cast, even when the field of view created a fisheye effect on the video.

In addition to tracking the source of the activity, the camera zoomed in automatically when motion was detected. When we used this feature, however, the footage wasn’t as clear as usual due to the image being zoomed.

In tests, Arlo Pro 4 was very successful at distinguishing whether a motion alert came from a person, a vehicle, or another source. When motion zones are enabled in the camera’s field of view (another Arlo Smart feature), washing on the line is no longer mistaken for a person.

Unlike the built-in siren, the spotlight is automatic when motion is detected, and can also be operated manually. It was useful to have a two-way talk feature, which enabled us to converse with anyone in the camera’s field of view. It was clear and distortion-free throughout the day, even in windy conditions due to the noise cancellation technology.

Arlo Pro 4 Smart Camera: App

Using the Arlo app is a breeze thanks to the clear and intuitive interface. In the list below, you will find pictures of the most recent motion recorded from each of the Arlo security cameras in your home.

In this screen, you can quickly adjust the settings for each camera, such as the speaker and microphone volume, triggering the siren or spotlight, or even setting up geofencing (via your smartphone), so that based on your location, the camera will turn on or off.

Using the Library tab, you can browse past footage, while the Mode tab lets you adjust how a camera behaves when you’re home or away. As we mentioned, the camera can be paired with Amazon Alexa, Google Assistant, or Apple HomeKit – although, as we’ve already mentioned, the latter requires a SmartHub. By doing so, you can view footage from the camera on your TV, or on a compatible smart display, as well as use the camera for home automation.

For video storage and advanced smart features, like object detection, you must subscribe to Arlo Smart. Following the three-month free trial, the camera will cost $2.99 / £2.49 / AU$4.49 per month. The service is similar to those offered by Ring and Google.

Arlo Pro 4: Battery life

  • According to Arlo, the battery lasts from three to six months
  • It takes around 3.5 hours to recharge
  • Swappable batteries

According to Arlo, the battery in the Arlo Pro 4 should last between three and six months. Due to the heavy testing, we do for this review, we cannot confirm how quickly ‘typical use’ drains the battery. The battery life you get is likely to depend on several aspects, such as the number of times motion is detected and Live View is triggered, whether a siren or spotlight is triggered and whether a two-way microphone and speaker are used during the day.

You can purchase a second battery, so you don’t have to leave the camera idle while the main battery charges. Using the supplied USB cable and power adapter, we found it took approximately three and a half hours for the battery to fully recharge.

Prod Cons
Integration with Alexa and Google Assistant HomeKit support only with hub
No hub required Video storage is not free
High-quality images


With the Arlo Pro 4, you can see detailed color footage during the day and at night thanks to the spotlight built into the camera. Unlike regular cameras, this weatherproof camera doesn’t require power from a wall outlet, and it also features intelligent features like AI-based tracking that can identify the source of motion alerts. Arlo Pro 4 can directly connect to Wi-Fi, unlike its predecessors, so you do not need a Smart Hub, but you will lose local storage and support for Apple HomeKit.
