  • Lymow One Plus in test: RTK robot mower for large areas & difficult terrain

    A Lymow One Plus robotic lawnmower with tank-like tracks sits on green grass, slightly dirty from use, in an outdoor area. www.commaik.de

    In the Lymow One Plus test, I show how this robotic lawnmower performs in practice without a boundary wire on a large and demanding area. With RTK navigation, chain drive, 45° incline and a cutting width of 40 cm, the Lymow takes a significantly different approach to classic robotic mowers. I tested the new Lymow One Plus extensively and compared it directly with the Lymow One. The focus is on performance, navigation, off-road capability and the question of whether this system is really worthwhile for large plots of land. The article provides a detailed insight into the technology, set-up, practical test and my experiences – including strengths, weaknesses and a…

  • 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…

  • Expand Reolink NVR storage space – Installing and configuring hard disks correctly

    A black Reolink NVR device is shown against a gray background. A large text in German reads "Hard disk retrofitting". The Reolink logo appears in the bottom left corner. www.commaik.de

    In this article, I will give a structured overview of the Reolink NVR models – maximum hard disk size and storage capacity and show what really matters when choosing the right HDD. A Reolink NVR is the central element of a camera surveillance system – and the storage strategy determines how long recordings remain available and how stable the system runs. I go into detail about the differences between RLN36, RLN16-410, RLN8-410 and RLN12W, explain the maximum hard disk size per model, show the correct choice of surveillance HDD and document the complete installation including formatting and storage management. I also explain how an NVR works with multiple HDDs and…

  • Heating optimization: How to make your diesel parking heater quieter – pump and silencer in the test

    A person in dark clothing stands by a white counter, holding a metal tube and a small rectangular device. Behind the counter is a white and black parking heater machine labeled Motour with various attachments and a red button. www.commaik.de

    In everyday life, a quiet diesel parking heater decides whether night-time operation is relaxed or permanently disruptive. In this article, I will show you from my own experience how the volume of a diesel heating system can be reduced in a targeted manner – without experimentation, but with tried and tested solutions. The focus is on the typical sources of noise such as the pump, exhaust gas, intake and hot air fan, as well as specific measures that I have used to make my heaters quieter step by step. The article bundles my experiences from numerous tests, measurements and conversions: from the quieter impulse pump, exhaust and hot air silencer…

  • Automatic litter box test: Self-cleaning litter box without odor – Mova LR10

    A modern, automated litter box with a circular opening sits on a wooden floor next to a wooden pillar and light gray wall. The litter box is empty and clean. www.commaik.de

    Self-cleaning litter boxes promise less effort, better hygiene and much more pleasant use in everyday life. Many cat owners are increasingly focusing on automatic solutions, especially if they have several cats or little time. With the MOVA MeowgicPod LR10 Prime, I tested a new litter tray in everyday use for several weeks – including set-up, app setup, cleaning cycles and use by two cats. This article is about my experience with a self-cleaning litter box that does many things differently to conventional litter boxes.
