4K in home security is finally here, thanks to Arlo's Ultra UHD smart cam

Beautifully crafted hardware design; Weatherproof and wireless for indoor/outdoor use; Fabulous 180-degree field of vision with little fish-eye distortion; Decent two-way audio; 4K UHD image clarity

Some features unavailable when using 4K video settings; No ability to view locally stored video without removing the microSD card; Double-tiered subscription required for 4K cloud recording

Ultra is packed with features and offers one of the best ecosystems for a security camera, if you can afford it.

The Arlo Ultra is by far the best smart security camera I've used: tThe footage is sharp, the features are top notch and Arlo's subscription package is both generous to those who don't want to pay and flexible enough to include those who do.

Crystal-clear; wide-angle 4K footage; Generous free cloud storage; Records in colour at night

Higher subscription price for 4K; Expensive camera; Most people can't view 4K footage easily

You'll pay a premium for the Arlo Ultra, but you get a lot for your money. This is the first security camera we've tested that streams and records 4K video, and there are no wires to deal with, making installation a snap.

No wires; Weatherproof; Detailed 4K imagery with a wide field of view; Color night vision; AI-based motion detection; Integrated spotlight; Auto-zoom and motion tracking; Amazon Alexa, Apple Watch, and Google Assistant support

Expensive; Requires a hub; Some features require a subscription

All works well and no problems setting it up

The Nest Cam IQ Indoor was the first security camera that I tested to have a 4K sensor, although this model downsampled all footage to 1080p. That makes the Arlo Ultra the first camera I've reviewed to be able to save 4K footage, delivering some of the most impressive and detailed images that I've...

Easy to install; Excellent 4K footage; Powerful modes gives you complete control over recording

No 4K recording out of the box; 4K streaming disables motion tracking

We review Arlo's brand new 4K camera Arlo security cameras put to the test Arlo security cameras put to the test

Brilliant footage at 4K; HDR makes 1080p superior; Great battery life

Plans getting expensive; High entry cost; New base station required

Bought a pack of these after reading mostly good reviews. It was horrendous. Would constantly disconnect. Wouldn't load. We couldn't even get it to work long enough for us to see if we were placing it in a good spot to then secure it. Returned and bought another brand which has been perfect!

The Arlo Ultra has its limitations, but if you're willing to spend the money you'll love the good image quality and smorgasbord of smart features.

Excellent image quality; Packed with features; Well-designed app

Expensive; Some features limit resolution

The Arlo range of security cameras has been a big success for Netgear in recent years -- so much so that the company decided to spin-off the Arlo division and float the new Arlo Technologies Inc. on the stock exchange last summer.

High-quality 4K video camera; with HDR; 180-degree panoramic video; with 12x digital zoom; Integrated spotlight and siren; Colour night-vision
