When comparing the Reolink Duo 3 WiFi, Duo 3 PoE, and Argus 4 Pro security cameras, their differences mainly lie in power source, network connectivity, resolution, storage, and night vision capabilities. The Duo 3 WiFi and Duo 3 PoE both offer 16 MP resolution for ultra-clear visuals, but the Duo 3 PoE uses Power over Ethernet (PoE) or DC power, while the Duo 3 Wi-Fi simply requires a plug-in power source and connects via WiFi. Both models feature color night vision (with spotlights) and differ slightly in local storage capacity, with the WiFi version supporting up to 512 GB and the PoE version up to 256 GB.
On the other hand, the Argus 4 Pro offers a battery and solar-powered setup, making it highly versatile for outdoor use, though its resolution is reduced to 8 MP. It supports up to 128 GB of local storage and boasts advanced ColorX night vision for detailed, low-light performance.
While the Duo 3 models are priced at $179.99, the Argus 4 Pro comes in slightly higher at $199.99, probably because of its solar-powered convenience and unique features.

Reolink Duo 3 WiFi is super easy to set up

The first thing I realized when I opened the box is, "Man! There are a lot of parts!" Once I got it all out and started assembling, I realized it wasn't that big a deal. You screw on the antennas and the base and then plug in the network cable and the power cable. Easy-peasy. It took less than five minutes.
From there, you plug the camera into a power outlet and into your router. This is just to set it up. Don't worry, the wireless part comes after. You unplug the Wi-Fi and then move the camera wherever you need to. It does need to be plugged into a power outlet to work though. So plan accordingly!
The Reolink Duo 3 WiFi is compatible with both 2.4GHz and 5GHz Wi-Fi frequencies and supports Wi-Fi 6. As with all Reolink cameras, there are no monthly fees necessary—the Duo 3 WiFi supports microSD card storage up to 512GB. This DC-powered camera is IP67 weatherproof and can be wall- or ceiling-mounted, so the only factor limiting placement is nearby powerpoints.
The Duo 3 Wi-Fi has innovative features
Last year, Reolink introduced the Duo 3 PoE, a groundbreaking dual-lens security camera that stitched two 16MP lenses together to create stunning, seamless 180-degree images. We even called it the best video quality I’d ever seen in a security camera. The only drawback? Being a PoE camera, its placement was limited by the need for a wired connection.
Later that year, Reolink launched the solar-powered Argus 4 Pro, which solved the placement issue. However, the resolution dropped to 8MP (still impressive), and keeping it charged could be tricky if sunlight was scarce.
Now, Reolink has addressed all these challenges with the Duo 3 Wi-Fi. It delivers the same incredible 16MP clarity, dual 4K sensors, color night vision, and wide 180-degree coverage as the PoE model, but all you need is a power outlet and a Wi-Fi router. Problem solved!
Motion tracking
Like its PoE counterpart, the Duo 3 WiFi also includes Reolink’s innovative Motion Track feature, which collates snapshots of multiple moments over a period of 15 seconds to show a time-lapse of a person, animal or other moving object without needing to scour through multiple video clips. Here’s a quick look at how it worked on the PoE model:

Crystal clear image and other goodies
While trying out the Duo 3 WiFi, we were struck by how crystal clear the image was. There was no pixelation at all. The Duo 3 boasts 16 MP Ultra-HD resolution, capturing every detail with incredible clarity.
Also, say goodbye to blind spots. Thanks to advanced image stitching technology, the camera provides a 180° ultrawide view with minimal distortion. This expansive perspective means you get the full story in one shot, eliminating the need for multiple cameras in larger areas.
The smart object detection categorizes recorded footage based on subject: people, vehicles, or animals. This makes it easy to find what you're looking for.

Images viewed in the app are a little hard to see unless you use full screen mode.

Darkness doesn’t have to mean losing details. The camera’s F1.6 aperture and built-in spotlights deliver vibrant color night vision, making it easy to identify critical details even in low light. Whether it’s day or night, you’ll have a clear and accurate picture of what’s happening.
Plus, with its eight bright spotlights and inbuilt siren, its presence alone can be enough to deter intruders.

What I didn't like
There's not much to dislike with the Reolink Duo 3. The live view in the app is a little hard to see. The image is small and stretched out. You can fix it by going into full-screen mode, but that takes a second, which you may not have time for if it's an emergency.
I also had a little trouble with the antennas that look like bunny ears. No matter how much I tightened them, they seemed to fall off after a while. It's not a big deal since you can just screw them back on, but ya know, I like things to stay put.
Final word
The Reolink Duo 3 Wi-Fi security camera is an excellent choice if you want a security camera with lots of features, local storage, and that doesn't need it's batteries charged on a regular basis. My only gripe with this camera is the live view in the app is a little hard to see without going into full-screen mode, and the antennas seem to like to fall off. Other than that, it's a fantastic camera.
