Duo 2 WiFi vs. Duo 3 WiFi: What's the Difference?

Beyond the jump from 8MP to 16MP, the Duo 2 WiFi and Duo 3 WiFi also differ in lens aperture, vertical field of view, and smart features.

Resolution: 4K vs. 16MP

Reolink security cameras are renowned for their combination of high resolution and advanced smart features. Most Reolink cameras have been upgraded to 4K resolution. The Duo 2 WiFi features a 4K resolution with a total of 4608x1728 pixels. The new Duo 3 WiFi boasts a UHD 16MP resolution, with a total of 7680x2160 pixels. This means that the picture captured by the Duo 3 WiFi has twice as many pixels as that of the Duo 2 WiFi. Consequently, the Duo 3 WiFi undoubtedly delivers more detail and better clarity than the Duo 2 WiFi.

Lens Aperture: F/2.0 vs. F/1.6

Another significant difference between these two cameras is their lens aperture. The Duo 3 WiFi has a larger lens aperture compared to the Duo 2 WiFi. With an aperture of F1.6, the Duo 3 WiFi's lens sensor allows more light to enter, resulting in superior night vision quality and excellent brightness in daylight footage. The Duo 2 WiFi's F2.0 aperture also ensures the camera captures the necessary details both day and night.

Vertical Field of View: 60° vs. 55°

You will also notice a slight difference between these cameras when checking their vertical field of view. The Duo 2 WiFi has a vertical field of view of 60°, while the Duo 3 WiFi only has 55°. One noticeable drawback of dual-lens cameras is that they have to compromise on their vertical angles to achieve the ultra-wide horizontal field of view. Although this difference may not be very noticeable, it's important to keep in mind if you are concerned about the blind spot directly below the camera.

Smart Feature: Motion Track

Another important upgrade of the Duo 3 WiFi is its motion track feature. Users can access this feature directly on the Reolink app. When the motion track is enabled, the movements of an object over a certain period can be compiled into one snapshot, and the snapshot of the entire movement will be emailed to the user with essential timestamps. Thanks to this feature, users won't have to download long videos that take up much storage space.

Duo 3 WiFi vs. Duo 2 WiFi: What's the Same?

Apart from all the differences mentioned above, the Duo 2 WiFi and Duo 3 WiFi also share some imporant features in common.

180-degree Field of View

Both of these cameras combine two lenses into one device, creating a 180-degree field of view. They provide ultra-wide footage without any image distortion. This design addresses the functional issues highlighted by users, specifically their difficulties with the feedback that 'one camera can't cover enough, and two are too cumbersome to install.'

Dual-band WiFi 6

They also operate on dual-band WiFi 6, which is crucial for WiFi security cameras to maintain a stable internet connection. Dual-band WiFi 6 connectivity allows users to switch between 2.4GHz and 5GHz WiFi based on their needs. At the same time, WiFi 6 provides a more stable network connection with fewer lags and buffering issues.

Color Night Vision

Both cameras use spotlights for color night vision. Users can switch between infrared black-and-white night vision and color night vision. The built-in spotlight can also be set to smart mode, where it will automatically light up when it detects motion events at night.

Local Storage

Both the Reolink Duo 2 WiFi and Duo 3 WiFi support a microSD card of up to 512GB for local recording. They can also work with Reolink NVRs and Home Hubs for additional storage options.
