Reolink Overview

Reolink is a renowned company that specializes in manufacturing and providing innovative security camera systems and solutions for residential and commercial use.

Best 4K Security Camera Reolink

Reolink is a pioneer that specializes in security cameras and systems for both consumers and businesses. Founded in 2009, the company introduced its first product in July of that year, rapidly expanding its reach to hundreds of thousands of people worldwide. Over the years, it has established itself as a trusted name in the security industry by providing high-quality, reliable products.

Reolink’s product range includes a variety of security cameras, such as dome cameras and high-resolution models, designed to meet diverse installation and environmental requirements. In addition to their cameras, it offers numerous accessories to enhance the functionality and convenience of its security solutions.

One of the key factors behind Reolink’s success is its commitment to innovative technology. Its products feature plug-and-play functionality, allowing for easy setup. Furthermore, it integrates network video recorders (NVRs) and IP cameras with 4K technology, providing users with superior video streaming quality.

The Reolink mobile app is another standout feature, enabling users to monitor their cameras from anywhere at any time. The app supports multi-channel viewing, motion detection alerts, and remote playback of recorded videos, enhancing the user experience and ensuring comprehensive security coverage. This remote access capability is crucial for modern security needs, allowing users to stay connected to their property no matter where they are.

Reolink Argus 4 Pro: The Blind Spot-Free Camera

The Reolink Argus 4 Pro is a battery-powered 180-degree security camera boasting Wi-Fi 6 technology, 4K resolution, advanced night vision, and AI-powered smart detection features.

Best 4K Security Camera Reolink Argus 4 Pro

The Reolink Argus 4 Pro is an innovative battery-powered security camera equipped with advanced features such as 4K resolution, extensive night vision capabilities, smart detection technology, seamless connectivity, and flexible storage options, offering users comprehensive surveillance solutions for both indoor and outdoor environments.

Key Features:

  • 4K UHD 180-degree view
  • Night and day color vision
  • Long battery life
  • Eco-friendly charging with solar panels
  • First battery-powered camera with Wi-Fi 6 technology
  • Hassle-free installation
  • Accurate detection and alerts
  • Versatile storage options
  • Remote access and smart features

First off, the Argus 4 Pro has 4mm dual lenses, offering a wide 180-degree view in sharp 4K resolution while overcoming image distortion issues with its Dual-Image Stitching Technology. Unlike wider lenses that spread pixels out, this design packs pixels more closely, resulting in clearer images. Also, it captures a lot of light thanks to its large f/1.0 lens and advanced 1/1.8” sensor. This means it can show full-color night vision even in very dim light conditions without the need for extra lighting (read: spotlights or infrared lights), so nighttime footage looks just as bright as daytime recordings.

On top of that, the Argus 4 Pro saves power with ColorX tech, cutting power use during night vision by 2W/h. This extends battery life by 30 percent compared to other 4K infrared cameras. The Reolink Solar Panel, which has a 6W output, keeps the camera charged even with little sunlight. In fact, it only needs 10 minutes of sunlight to provide enough juice for 24 hours, which makes for an eco-friendly energy solution.

It’s worth noting that the Argus 4 Pro has a wide 180-degree Passive Infrared (PIR) sensor for broad coverage and fewer missed alerts. The camera is baked with advanced AI that allows it to analyze motion detected by the sensor to correctly identify humans, vehicles, and animals and ignore common false triggers like wind or rain. That way, users will only be notified about relevant alerts.

Remarkably, the Argus 4 Pro is the first-ever battery-powered camera to feature dual-band Wi-Fi 6 technology. The takeaway here is it can transfer data super fast with little to no delays and better stability, allowing for smooth 4K streaming and real-time previews even when the network is busy.

As for storage options, the Argus 4 Pro supports microSD cards of up to 128GB and the Reolink Home Hub with up to 6TB of storage and RTSP (Real Time Streaming Protocol) support. For the record, none of these need a monthly subscription, making the setup a cost-effective option overall.

Last but not least, users can remotely access their cameras, receive instant alerts for suspicious activities, and even use two-way audio for real-time communication through the Reolink app or client. Other smart features include smart playback and adjustable motion sensitivity to reduce false alerts.
