Duo 3 PoE Review

A user of the Duo 3 PoE shared their experience like this:

Based on this user's review, the Duo 3 PoE represents a significant advancement for Reolink PoE cameras.

Key Similarities Between Duo 3 PoE and Argus 4 Pro

When we compared the Reolink Duo 3 PoE and the Argus 4 Pro, we were surprised that they share some standard features.

180-Degree Field of View

Both cameras combine two lenses into one housing, boasting a 180-degree field of view. Thanks to Reolink's dual-image stitching technology, these dual-lens security cameras can now synthesize expanded 180-degree panoramic video feeds in real time. Integrating live feeds captured by the two lenses into one larger cohesive composite without distortions, the Argus 4 Pro and Duo 3 PoE can cover an expansive area, leaving no blind spots.

Smart Detection

Another fundamental similarity between the new Argus 4 Pro and Duo 3 PoE is that both cameras have advanced smart motion detection features. They all have the advanced capability to differentiate and identify specific types of objects or entities, such as person, vehicles, and animals, within their field of view. Smart motion detection enhances the functionality and effectiveness of security systems by reducing false alarms and providing more relevant notifications. For example, in the unfortunate event of intrusion, these cameras can focus on potential intruders or visitors rather than being activated by other moving objects.

Two-Way Audio

Argus 4 Pro and Duo 3 PoE can transmit and receive audio. That is, they all include a built-in microphone and speaker and allow for real-time communication between the person monitoring the camera and individuals at the camera's location. Users can speak through the camera via the Reolink app to interact with people near it, such as delivery personnel, visitors, or potential intruders.

Local Storage

Another similarity lies in the storage options each device offers. The Reolink Duo 3 PoE supports local storage with a MicroSD card of up to 258GB. Users can also integrate it into their existing Reolink camera systems and store the footage in Reolink NVRs. Similarly, the new Argus 4 Pro supports local storage with a MicroSD card of up to 128GB, and users can store the data locally in the Reolink Home Hub.

Key Differences Between Argus 4 Pro and Duo 3 PoE

The key difference between the Reolink Duo 3 PoE and the Argus 4 Pro lies in their network connectivity and power supply. The Argus 4 Pro is a battery-powered Wi-Fi security camera, while the Duo 3 is a wired PoE surveillance camera.

Design: Compact vs. Professional

The first noticeable difference between the two cameras is their design. The Duo 3 PoE maintains the traditional look of the Duo series, similar to previous models like the Duo 2 PoE and Wi-Fi. In contrast, the Argus 4 Pro features a significant design update. This compact camera, with its dual front-facing lenses, resembles a mini robot.

Network Connectivity: Wi-Fi vs. PoE

The key difference between these models is their connectivity options. The Duo 3 PoE uses Power over Ethernet technology and obtains power and network connections through a single Ethernet cable. When connected to a network switch, router, or PoE injector, the camera can be controlled over the network.

In contrast, the Argus 4 Pro is a WiFi-enabled surveillance camera incorporating Wi-Fi 6 technology. Before installation, users simply need to download the Reolink app, scan the QR code on the camera, and sync it with their home Wi-Fi. The Argus 4 Pro also supports Bluetooth to connect the camera to Wi-Fi. Wi-Fi 6 technology enhances speed and reduces buffering issues for a smoother experience.

Power Supply: Battery/Solar Panel vs. PoE-Enabled

The Ethernet cable also delivers electrical power to the Duo 3 PoE, so there is no need for a separate power adapter. In contrast, the Argus 4 Pro is battery-powered. With its built-in battery, it is an energy-efficient option. Users can also purchase a separate solar panel to recharge the battery using solar energy.

Resolution: 4K vs. 16MP

Another distinction between these two cameras is their resolution. The Duo 3 PoE boasts an impressive 16MP resolution, while the Argus 4 Pro is part of Reolink's 4K battery line. A 16MP image has approximately 16 million pixels, whereas a 4K resolution typically contains about 8.3 million pixels.

For a battery-powered surveillance camera, 4K is more than sufficient for high-end surveillance and monitoring needs because higher resolution usually means higher power consumption. Recording in 16MP can use more power as the camera needs to process and store more data. Additionally, high-resolution recording can drain the battery faster, requiring more frequent recharging, which is inconvenient for users who prefer longer intervals between charges.

Night Vision Capability: ColorX Tech vs. Color Night Vision with Spotlight

One of the most significant updates to the Argus 4 Pro is its night vision capability. This dual-lens camera provides vivid color images at night without relying on a visible spotlight. Thanks to the powerful ColorX technology, the camera features a larger F/1.0 lens aperture and an upgraded 1/1.8 image sensor, enhancing its night vision performance.

In contrast, the Duo 3 PoE offers two night vision modes: black-and-white and color night vision with spotlights. To use the color night vision mode, the embedded spotlight must turn on to provide additional light when there is no other light source available.

Reolink Duo 3 PoE vs Argus 4 Pro: Which One to Choose

Although both cameras are ideal for home and business use, the choice of which camera to use depends on the specific scenario. The Duo 3 PoE is the best option for professional surveillance scenarios requiring precision and accuracy. It is perfect for monitoring stores, restaurants, and warehouses because 16MP provides reliable and high-quality footage to ensure the security of these business environments.

On the other hand, the Argus 4 Pro is a great beginner-friendly choice for those new to home security cameras. Homeowners can place it in their front or backyard for daily monitoring. A high-quality 4K image ensures that the perimeter is secure. This camera is also suitable for porches or doorways. Users can check on visitors or deliveries with ease via the compatible Reolink app. The Argus 4 Pro offers convenient and adequate security for residential settings.
