In this review, we dive into Arlo and Reolink's high-end Wire-Free Spotlight Cameras; the Ultra 2 vs the Argus 3 Pro.
We say "Wire-Free" instead of "Wireless" as these cameras are battery powered and transmit over Wi-Fi, which makes them pretty straightforward to install. There are plenty of differences between these two though, so let's begin!
Arlo Ultra 2 vs Reolink Argus 3 Pro Head to Head
Key Features in Common
Power & Data Feeds
As discussed, both of these cameras are wire-free so they are primarily battery powered. This can be a hassle as they require regular charging. The Arlo has the option of powering via AC through a standard socket while the Argus 3 Pro can be hooked up to DC power or an add-on solar panel.
The Reolink camera has the added benefit of transmitting on 5GHz Wi-Fi which is great if you have a router close by. 2.4GHz will transmit further which is why it is the standard in Wi-Fi cameras.
Camera & Lens
The Arlo has a larger image resolution recording in 4K which is good for digitally zooming in on faces or number plates. The Arlo's image sensor is also bigger which supports the higher resolution and can provide better night vision as more light can hit the sensor.
Both cameras have both infrared and full-color night vision with integrated spotlights. This is great for identifying people at night when the spotlight activates.
Each camera has two-way audio with integrated speakers and microphones. They also have the ability to enable an audible alarm through the speaker.
Storage & Interoperability
While both cameras have microSD slots, the Reolink footage is easier to access via the app. Both have optional cloud storage while the Arlo allows recording to a USB Flash Drive hooked up to the Wi-Fi hub.
Arlo has the added benefit of Alexa, Apple Homekit, and Samsung SmartThings integration while Reolink allows broadcasting the footage via Chromecast or a Nest Hub screen.
The big downside of the Arlo Ultra 2 is you need to subscribe to their monthly plan to gain access to all of the features (specifically Smart / AI Notifications). Reolink also offers a free cloud storage plan with paid plans available. Arlo's plans can get expensive for 4K storage.
Both cameras have smart motion detection features, although as mentioned, it is an added cost for Arlo. Person and vehicle detection dramatically reduces the number of false alarms and false notifications.
With the 4K resolution, the Arlo offers digital zoom tracking of people who trigger the smart motion detection - up to 12x. Reolink offers 16x digital zoom, however, has a smaller resolution so quality will slightly suffer.
From our research we could not find an exact IP rating for the Arlo Ultra 2 - they just mention it is weather resistant. Reolink on the other hand has IP65 ingress protection.
The Arlo can operate in a slightly larger temperature range, which may be important if you need to install it in extreme conditions.
While both cameras have iOS and Android apps, Reolink has Desktop and Web Apps for which the Argus 3 Pro is compatible. (A separate NVR may be required)
