  • The best Reolink 4k PTZ surveillance cameras in comparison: 823S2 vs 823S1 vs TrackMix vs TrackFlex in test

    A 4K PTZ Reolink security camera monitors a man walking towards a large house at dusk. A digital overlay highlights the camera's facial recognition and zooms in on the man's face with a blue square frame. www.commaik.de

    For me, Reolink is one of the most exciting manufacturers of modern 4K PTZ surveillance cameras for indoor and outdoor use. In this Reolink surveillance camera comparison, I analyze several high-performance models – from classic PTZ cameras with optical zoom to dual-lens and floodlight variants for outdoor use. The focus is on image quality, motion detection, night vision, PoE vs. WLAN, local storage without a subscription and the question of which camera is really suitable for large properties, driveways or security-relevant areas. I will show you my practical experience with the RLC-823S2, RLC-823S1, TrackMix and TrackFlex and categorize the models technically and strategically. The aim of this article is to…

  • Reolink Argus Eco Ultra review: 4K rechargeable surveillance camera without subscription

    A man thoughtfully poses in front of images of the Argus Eco Ultra cameras, a solar panel, and a backyard pool. The Reolink logo is at the top right, with "Argus Eco Ultra" displayed prominently in bold text. www.commaik.de

    The Reolink Argus Eco Ultra is a 4K battery-powered surveillance camera that works completely wirelessly and impresses with smart motion detection and color night vision. The test shows how good the image quality really is, how reliably the motion detection works and whether the battery delivers what it promises in practice. There is also a look at the storage options with microSD card, Home Hub and Home Hub Pro as well as integration into smart home systems such as Alexa, Google Assistant and Home Assistant.

  • Reolink Duo 3 PoE surveillance camera tested against 2 RLC 810A

    A man stands thoughtfully next to a large question mark, with three Reolink security cameras and the Reolink logo displayed on a gray background, highlighting Reolink’s commitment to smart security solutions. www.commaik.de

    In my latest smart home project, I replaced my two Reolink RLC-810A cameras with the Reolink Duo 3 PoE surveillance camera with dual lens. I was particularly interested in whether the 180° detection of the Duo 3 PoE could actually improve the monitoring of my driveway and carport. With its 16-megapixel resolution and 2-way communication capability, the Duo 3 PoE promised superior technology and more comprehensive security. But would all the effort and financial investment really be worth it or were the two old camera models better? I would like to explore these questions in this blog post.
