Arlo Essential 3 2K Indoor Security Camera


Verdict

A cheaper, lighter camera for indoors, the Arlo Essential 3 2K Indoor Security Camera might have a lower price than the rest of the range, but it has the same core features. That includes excellent object detection options, a brilliant app and high-quality 2K footage. With its clever privacy shield this is a top indoor camera, provided you don’t mind paying the relatively high subscription costs.

  • Good value

  • Clever privacy shield

  • Excellent footage

  • Powerful object detection via a subscription

  • Subscriptions are expensive

Key Features

Introduction

As good as the Arlo system is, fitting one of the weatherproof, battery-powered cameras seems a bit overkill. The Arlo Essential 3 2K Indoor Security Camera redresses the balance: the same core features, but in a cheaper body that needs to be permanently wired, with the addition of a privacy shutter.

It gets all of the basic right, and image quality is very good, but is the camera worth the price of the subscription you’ll need?

Design and Installation

  • Wall or desk mounted
  • USB-C power
  • Privacy shutter

As there’s no battery, the Arlo Essential 3 2K Indoor Security Camera is quite a bit smaller than the other cameras in the range, such as the Arlo Pro 6 2K. All you need to set it up is a power socket within reach of the required USB-C cable.

This camera can be sat on a desk or bookshelf, which is the easiest way to install it. If you prefer, the stand can be moved to the back and used as a wall mount, giving a more permanent installation.

One key difference that you’ll notice with this camera, compared to the other Arlo models, is the integrated privacy shield: a plastic cover that swings up in front of the camera to prevent it from recording.

I think that’s quite important for indoor cameras, and it’s nice to have this privacy feature, which also gives you a simple way to check if the camera is on or off.

Features

  • Subscription required for main features
  • Custom AI detection option
  • Very powerful object detection

This camera is quick and easy to connect to your Wi-Fi (2.4GHz and 5GHz networks supported) and into the Arlo app. This app remains one of my favourite, offering a brilliant range of controls and a simple way to find footage.

Before I get into the features, I have to point out that you need a subscription to make the most of the camera. If you don’t want to pay monthly, then don’t buy this camera.

A basic Arlo Secure subscription costs £7.99 a month for a single camera and includes just seven days of video history, which is stingy compared to the competition. You also get Basic Person, Animal, Package and Vehicle Detection.

There’s also a multi-camera version of this plan for £11.99 a month, covering up to four cameras. It’s not clearly advertised on the website, but you can find it in the app under the subscriptions section.

If you want the more advanced AI features, you’ll need Arlo Secure Plus, which costs £19.99 a month for unlimited cameras, gives you 14 days of video history and supports resolutions up to 4K.

At the higher tiers in particular, Arlo Secure is expensive compared with rivals such as Ring, which starts at just £4.99 for a single camera, with higher tiers adding extra features for cameras and the Ring Alarm.

I’d stick with the standard plan, especially if you’re using a 2K camera, although I’ll also explain the new AI features.

With Arlo Secure, you do get a lot of controls. With the basic plan, the object detection options dramatically cut down the number of motion alerts that I got. It’s unlikely that you’ll need them inside, but activity zones can futher reduce false alerts in some situations.

On the most expensive package, there’s support for facial recognition, although this only works on a single camera in your system. Realistically, it makes more sense to have this option on an external camera.

Vehicle recognition (like facial recognition) is also available, although this is a feature that you’re unlikely to need indoors unless something goes horribly wrong.

Custom detection on the higher tier is the only detection type of its kind that I’ve seen. With this, you can train the camera with before and after shots to spot your own custom events, such as the front door being left open. I find that I need a big enough difference between images for the feature to work, but it does open up a lot of possibilities.

There’s also support in the more expensive package for fire detection. If the camera spots a fire starting it can send an alert.

But, as nice as the extras are, they don’t feel essential, and I’d stick with the more basic cloud subscription options to save money.

In the app, there are three modes: Arm, Arm Home and Standby. For each mode, you can set which cameras you want to have on. They’re essential for an indoor camera, where you won’t want to record everything going on in your home. 

Modes can be set manually, scheduled or even triggered by your location, so you can largely automate the process.

With the Arlo Essential 3 2K Indoor Security Camera, when it’s set to not record the privacy shield quickly snaps into position.

Recorded footage can be accessed via the app, with loads of filtering options: date, specific camera and even what triggered the motion (person, vehicle, etc). There’s then a thumbnail list of events, which can be watched and saved to your phone for longevity.

Performance

  • Excellent 2K video
  • Sharp video at night and during the day

With its 2K (2304 x 1296) resolution, the Arlo Essential 3 2K Indoor Security Camera has the same resolution as the bulk of the rest of the range of cameras. This step up from Full HD is a good one, adding a bit more sharpness and detail, but without the file size and bandwidth requirements of 4K.

There’s a 130° field of view from this model, which is enough to capture most of a room, provided the camera is sensibly placed.

In daylight, the footage is excellent, as good as you can expect. Even in the busy Trusted Reviews Home Technology Lab, there’s detail all the way through the frame, and faces are sharp and clear.

At night, the Arlo Essential 3 2K Indoor Security Camera switches to black and white footage, using IR to light up the space. These IR lights work well, with the main frame sharp. Moving objects become a bit softer, but even so, it’s easy to find a frame where people are easy to identify. Again, you don’t really get better than this.

Should you buy it?

You want a smart, quality indoor camera

Excellent 2K footage day and night, plus a wide range of detection options make this camera a winner.

You want a camera with lower monthly costs

Arlo Secure is quite expensive, and there are cameras with cheaper or even no monthly subscription costs.

It’s easy to assume that vehicles all had internal combustion engines until very recently. Gasoline and petrol engines were the standard for decades, after all, so why would early vehicles be any different? In reality, the early days of the automobile era were more varied than you might expect, and even featured a range of electric cars. Yes, despite electric vehicles not truly taking off until the 21st century, the first electric vehicles are much older than you think; drivers in the 1900s were going around town in electric vehicles — and where there are EVs, there are charging stations.

One such station, visible in the image above, was the creation of General Electric. Formally called the mercury arc rectifier, it took alternating current and sent it through vaporized mercury in a glass tube. This converted it into direct current, which powered up the EV’s battery. The woman in the image, who’s charging a Columbia Mark 68 Victrola, is standing at the control panel, which allowed a user to adjust power levels. 

These chargers could be installed everywhere, including homes, businesses, and public parking garages, supporting the electric vehicle boom of the early 20th century. While 21st-century EV chargers have come a long way from where they were, the basic building blocks are all still there, and it’s fascinating to see.

How EV chargers have evolved since the early 20th century

EV charging has changed a lot in some ways — but not in others. At the core of it all is the aforementioned conversion from AC to DC, which still happens when you charge modern EVs at standard charging stations. The difference is that your vehicle’s on-board charger performs the conversion, not the charger. Old EV chargers took between several hours and a day to charge, and current-day units can similarly take a few hours to well over a day from empty, depending on the charger’s speed. Fast chargers, which provide DC directly, can cut this down to around an hour or less.

Old-school and modern EV chargers also differ in how they provide power to the vehicle. Mercury arc rectifiers connected directly to the negative terminal of the lead-acid battery that needed charging. Nowadays, EVs use dedicated charging ports. Battery swapping was also commonplace in the early 1900s, and companies like General Electric tried to cash in by offering to replace drivers’ old, run-down batteries with new ones for a fee. That’s not yet possible with most mainstream EVs, although companies like Stellantis have tried to introduce EV battery swapping with moderate success.

Even if they were unrefined compared to today’s models, early EVs seemed to be on to something. Why, then, did electric cars fail, and how did gasoline end up becoming the predominant power source for vehicles?

What led to the downfall of the original wave of electric cars

EVs were no mere fad in the 1900s and 1910s. According to the 1900 United States census, 1,575 of the 4,192 vehicles sold that year were electric, with the value of these early EVs — $2,873,464 — accounting for more than half of the total market value of $4,899,443. It wasn’t just EVs, either; other sources of propulsion, like steam, were also vying for a foothold in the automobile market. By the 1920s and 1930s, though, these had all been superseded by the internal combustion engine.

One of the major drawbacks of early EVs was the fact that electricity was not yet widely available. Electrical hookups were a rarity outside of major cities, limiting the use of these vehicles. The lead-acid batteries they used also had their fair share of issues. They needed to be inspected, cleaned, and repaired every few days, making them more of an inconvenience than anything. Worse yet, they had poor mileage, and, with chargers possibly out of reach, many likely didn’t want to risk being stranded while out for a drive.

Eventually, price reductions for gas cars and improvements such as electric starters and better reliability prompted buyers and automakers alike to move away from electric rides. Thus, while the best-selling EVs of 2026 show that it’s a good time for EVs, this electric boom plainly isn’t the first of its kind. Early EVs eventually fizzled out, but they still set the stage for our current fascination with electric vehicles.
