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

Years ago, Reolink introduced its Duo series, a lineup of dual-lens security cameras, with one of the standout products being the Duo 2 PoE. However, the innovation doesn't end there. In Q1 2024, Reolink will release the latest addition to the Duo Series, the Duo 3 PoE. This article will compare the key differences between these two models and explore significant upgrades of the Duo 3 PoE.

Reolink Duo 2 PoE vs. Duo 3 PoE: Key Differences

The critical difference between Reolink Duo 2 PoE and Duo 3 PoE is their resolution capabilities. While the Duo 2 PoE delivers a remarkable 4K UHD resolution, the Duo 3 PoE provides an impressive clarity of 16MP.

Resolution

When comparing the resolution of these two security camera models, there's a notable difference in the level of detail they capture. The Duo 2 PoE boasts a 4K 8MP resolution (4608X1728), offering clear and crisp imagery. However, the Duo 3 PoE steps up the game with a higher resolution of 16MP (7680x2160). The 16MP resolution provides even more detailed and sharper visuals. In simple terms, the 4K resolution ensures a high-definition view. In contrast, the 16MP resolution takes it a step further, with nearly twice the number of megapixels within a single image.

Weatherproof

Another distinction between these two lies in their weatherproof capability. Although both Duo 2 PoE and Duo 3 PoE can be installed in outdoor spaces, the Duo 3 PoE has a higher IP rating, IP67. Meanwhile, the Duo 2 PoE has an IP66 rating.

IP67 security cameras are dust-tight and capable of withstanding temporary immersion in water for a certain period (1 meter-deep water for 30 minutes, under specific test conditions). Compared to the Duo 2 PoE, the Duo 3 PoE is more suitable for locations where they may be subjected to heavy rain or splashes.

Smart Features

Reolink also incorporates some new smart features into the Duo 3 PoE. For example, the Duo 2 PoE only allows for smart pet detection, while the Duo 3 PoE has animal detection. It can detect more than just cats and dogs. Moreover, you can use the motion track functionality via the Reolink app. This new feature allows users to see a person's whole path during a period in just one image.

Reolink Duo 2 PoE Review

The Reolink Duo 2 PoE stands out as a remarkable security camera, as highlighted by a satisfied user who describes it as an exciting and unique device. He said: "This camera is an interesting one. It isn't for everyone, but its unique set of features might be good. We had the previous 2K WiFi version, and this one is a fantastic upgrade".

Coming from the earlier 2K WiFi version, the Duo 2 PoE is praised as a fantastic upgrade. The standout feature of this camera is its dual-camera setup within a single housing. This design provides a double-wide field of view through two distinct video streams. The user also emphasizes that depending on your situation, this can be annoying or a significant advantage. For their use case in monitoring a driveway with package deliveries, the ability to set up motion alerts independently for each camera stream proves advantageous.

Reolink Duo 3 PoE Upgrades

The Reolink Duo 3 PoE integrates various new technologies to improve surveillance effectiveness and enhance the user experience simultaneously.

16MP Resolution

The first and foremost upgrade is the 16MP resolution. Due to the 16 million pixels in each frame captured by the camera, the Duo 3 PoE can offer fine details and provide optimal clarity in the live feed. It can easily capture persons, vehicles, and animals within the monitoring area, and users can zoom in digitally for more details. Moreover, the 180° panoramic view can reduce the blind spots, including more components in the picture.

Motion Track

Another innovative feature of the Duo 3 PoE camera is the built-in Motion Track. By overlaying multiple tracks and positions of people, vehicles, or animals over a certain period into a single picture, Duo 3 PoE users can monitor footage within seconds and remove hurdles like video buffering delays and having to watch multiple footage playback to confirm abnormal activity. Furthermore, this functionality reduces the file storage space.

Dual-Image Stitching Algorithms

Reolink uses unique image stitching algorithms to synthesize expanded 180-degree panoramic video feeds in real-time. This algorithm seamlessly integrates images captured by two lenses into one without invisible boundaries, covering larger horizontal areas. Thanks to this technology, users do not need to move cameras, adjust lenses, or compromise resolution quality by strategically placing these cameras.

Reolink Duo 3 PoE vs. Duo 2 PoE: How to Choose

The ultimate choice between Duo 2 PoE and Duo 3 PoE depends on your needs. Firstly, consider the level of detail you want in your surveillance live footage. A 4K security camera is enough for many standard applications. But suppose you require exceptional information and clarity, for example, the captures of license plates of facial features in a distance. In that case, you can consider the Duo 3 PoE.

Secondly, you can also consider factors like the size of the area you want to monitor, the distance from the camera to the subject, the specific security requirements of your environment, etc. At last, assess your budget. Cameras with higher resolution may cost more.
