  • Reolink Altas PT Ultra: The powerful 4K battery-powered surveillance camera in a test

    A man points to security camera equipment, featuring a Reolink Altas PT Ultra camera, solar panel, and hub, with a backyard pool and patio area in the background. The Reolink logo is displayed on the left. www.commaik.de

    The Reolink Altas PT Ultra is an impressive surveillance camera that I tested in my latest project. With 4K resolution, ColorX night vision and 360° auto-tracking, it offers powerful functions for outdoor use. In comparison to the Reolink TrackMix PoE and the RLC-1212A, I examined the image quality during the day, at night and at dusk and found interesting differences. In this article, I describe my installation procedure, how the cameras work and which models are particularly suitable for certain areas of application.
