What if a building not only consumed energy but could also store some of it within its own structure? Scientists are working on a material that may bring us closer to such a solution in the future. It involves a special cement-based supercapacitor that can store energy whilst retaining the strength required for structural elements. The idea is part of a broader concept for the buildings of the future, in which energy from renewable sources would not only be produced on-site but also stored as c...

We present the implementation of a modern RTV/SAT system in a newly built residential estate in Wrocław. It comprises a complex of 8 buildings set on two shared underground car parks, containing 13 stairwells and a total of 301 residential units (ranging from 15 to 30 flats per stairwell).

The installation and commissioning of a CCTV system requires the correct positioning of cameras, image checks and device configuration. In the case of IP cameras, it is also necessary to check network connectivity, power supply and operating parameters. These tasks are often carried out even before the target infrastructure is commissioned. In such situations, the use of a Signal multifunctional CCTV tester, such as the MT-18 M3218 or MT-11 M3211, makes the installer’s job much easier....

A bispectral camera is a solution that combines the advantages of traditional video surveillance and thermal imaging. It is equipped with two sensors, one of which operates in the visible light spectrum, whilst the other utilises infrared radiation for thermal imaging. The visible light sensor enables the identification of people and objects in adequately lit conditions, including when additional lighting is used at night. The thermal imaging sensor, on the other hand, does not require the scen...

Installers carrying out reflectometric measurements of fibre-optic lines may sometimes observe a certain anomaly on the reflectogram and in the event table. These are known as ‘gainers’, i.e. fibre connection points (usually a splice) where an amplification of the backscattered signal towards the reflectometer can be observed....
