We have published a technical column titled "How to Choose Camera-less Monitoring" (A4, 4 pages, with illustrations). When considering monitoring devices, the discussion often revolves around "whether to use a camera or not," but what truly matters is the perspective of what you want to notice in that location. This document organizes the differences between three methods: camera, millimeter-wave radar, and mat/load-based systems, and summarizes how to choose based on suitability for different locations. [Contents] - There are three main types of monitoring methods (Camera / Millimeter-wave radar / Mat/load-based) - Quick reference table of differences between methods (What can be detected / Installation and environment / Usability / Privacy) - Choosing based on scenarios (Falls at night / Toilet and changing room / Confirming presence in living spaces, etc.) - Three common decision points that can cause confusion on-site, and three frequent mistakes - Five items to check during selection This document organizes the general trends for each method. Since the actual feasibility and specifications vary by product, if you let us know the location and what you want to notice, we can assist you with choosing the right option.

We have published a technical column titled "Differentiating Between Primary and Secondary Batteries" (A4, 4 pages, with illustrations). When choosing batteries, it is common to think that "being rechargeable is better," but what really matters in practice is whether to maintain the equipment through replacement or through recharging. This document organizes the differences between the two based on the direction of the reaction and summarizes a method for selecting based on application. [Contents] - Quick reference table of differences (charging/maintenance methods/amount of electricity lost during storage, etc.) - Selection method based on reverse lookup from applications (not used for long periods/daily charging/large current needed for short durations/difficult to replace when integrated) - Three common decision points that can cause confusion on-site and three frequent mistakes - Five items to check during selection (operating environment/current output/transportation and labeling regulations, etc.) This document organizes the general trends by type. Since specific specifications vary by product, please let us know your application and usage environment, and we will assist you in consulting on part numbers that meet your conditions.
