Reolink Duo camera Overview

The Reolink Duo is a camera with two lenses and a field of view of 150 degrees.

This camera can show you a side-by-side window with the image from both lenses with a little bit of overlap. Enough to cover the entire scene using two video feeds.

Each lens has a resolution of 4MP, bi-directional audio communication, night vision, spotlight, micro SD card slot and H.264 compression.

There are 4 different versions of this camera.

  • PoE (Power over Ethernet) which is powered by the network cable.
  • WiFi version which is powered by a power supply.
  • 4G Battery-Powered Version
  • Wi-Fi Battery-Powered Version

My first impression

I received the Reolink Duo WiFi version, so I can talk about this specific model.

Out of the box, the camera is sturdy and impressive. It looks like Reolink is using good material and paying attention to the details for the camera design.

It comes with two mount threads which make it easy to install on a ceiling or a wall.

The setup is fast and easy since it's done by just adding the camera to the Reolink app after reading a QR code with the mobile phone camera.

I noticed that the camera works fine in places with a good light condition, but it struggles to work with the contrast of light (more on that later).

What is on the box

The Reolink Duo comes with everything necessary for the installation.

The box brings the camera, a wall mount, a UTP (network) cable, a power supply, an power extension cable,  plastic anchors, installation screws,  weather-proof cable protection,  mounting plate, Wi-Fi Antennas, a quick start guide and stickers.

And here's the camera. It's sturdy, the material looks good, and it's design resembles a bee ( that was what she said as soon as she saw the camera) 🙂

In the front part of the camera, there is the lens, Infrared LEDs, spotlight LEDs that turn on to illuminate the area.

In the lateral, there's a Reolink logo and a QR code for easy installation.

The camera bottom

There's a micro SD card slot in the bottom part of the camera, a speaker, and a mounting thread.

There's also a reset button under the SD card slot cover.

The Reolink Duo features

Let's take a look at some of the camera features...

Camera resolution

The camera can capture images with 4MP resolution on each lens, which means you can set up the camera to record videos with 2560 x 1440 pixels.

The camera has good quality as you can see in the pictures below.

As you can see, the camera uses its two lenses to capture the entire room.

The image below shows how the camera is displayed in the Reolink software or the NVR. As you can see, it's possible to see the room in 150º field of view.

The Reolink Duo is weatherproof, so you can install it outdoor, and it won't have any problem with rain. The image below shows an example of an outdoor installation

You can use the camera to have this type of wide-angle visualization.


If an intruder comes close to the camera, it can turn the spotlight on to illuminate the area; enabling or disable this feature is possible.

Bi-directional audio

The camera has a speaker and a microphone that you can use for bi-directional audio communication to hear the sounds around the camera and speak into a mobile phone to someone close to the camera.

Alert notification

The camera can send notifications via  mobile phone and email.

It's also possible to send pictures to an FTP server.

Trigger Sound Alarm

You can trigger an alarm by pushing a button on the App.

There's a siren sound that can scare people and make them run away 🙂

Here's a demonstration of the sound; just check it out below.

Motion Detection

The camera detects motion and uses it as an event for recording.

You can adjust the sensitivity according to your needs.

SD Card Recording

You can use a micro SD card to record the videos.

 I recommend you buy a class 10 micro SD card to avoid problems.

Just stick the card into the camera and turn on the recording via mobile App.

You can set the Post-Motion Recording Duration, which gives you extra footage after the event that triggered the recording. 

Wi-Fi connection

The camera can connect to 2.4GHz and 5GHz Wi-Fi routers.

The 5GHz frequency is less susceptible to interference since there are more available channels to choose from.

This a very important feature that is not available in most smart cameras.

Multiple-stream feature

The camera allows the configuration of different video streams.

You can have a high-resolution video stream and a second one with lower quality. 

You can choose each one to use to save bandwidth.

Reolink calls them Fluent, Balanced, and 4MP.

When you choose the Fluent option, the video quality is sacrificed so the camera can work better with the transmission over mobile devices using cellular data.

When connected to a Wi-Fi router the high-quality stream (4MP) can be used.

The Pros and Cons of the Reolink Duo

OK, it's time to talk about the pros and cons of the Reolink Duo camera.

Based on the tests I've done for this review, here are the results...


  • High-quality video recording
  • 150º Field of View
  • Weatherproof
  • Bi-directional audio
  • Micro SD recording
  • Mutiple-stream feature
  • Easy to set up
  • IR LEDs
  • Spotlight


  • No Alexa and Google Home integration
  • No Backlight compensation (WDR)


The Reolink Duo is an excellent camera.

I definitely think it's a good product for the price.

The camera struggles a little bit with light contrast due to the lack of WDR (Wide Dynamic Range) feature, but it's a good fit for most scenarios with good light.

I hope this review can help you make up your mind and make the right decision.

I'm not a Reolink employee neither the company representative. 

I received the product from Reolink to evaluate and write a review about it but I don't have any obligations to enforce the product advantages.

My opinion about the camera quality is based on my tests and analysis of the features and I'm just giving the final verdict accordingly.
