With the development of technology and the increasing importance of images in our daily lives, there is a growing demand for screens that can convey reality with absolute precision. Researchers from Sweden's Chalmers University of Technology, the University of Gothenburg and Uppsala University, have developed a novel screen technology that uses the smallest pixels ever. In doing so, they have achieved the highest resolution that the human eye can perceive. The new solution is based on so-called...

The choice of the right UPS (Uninterruptible Power Supply) depends on the type of equipment you want to protect and how important continuity of power supply is to you. There are three basic types available on the market: Offline (standby) UPS, Line-interactive UPS and Online (double conversion) UPS.

The SIGNAL PRO series is a line of A-class multiswitches designed for professional SMATV systems. These devices are used in multi-family buildings, hotels, office buildings and wherever satellite and terrestrial signals need to be distributed to multiple reception points. SIGNAL PRO multiswitches are made in a cast housing with shielding class A, which guarantees high resistance to electromagnetic interference (EMI)...

The door stations of the IP Villa 2nd generation video door entry system from the DS-KV8xxx series, have 2 built-in relays that are independently triggered, which allow, for example, the control of the gate or entrance gate. By default, the second relay at the door station is deactivated and must be activated using the iVMS-4200 application or via a web browser. Triggering of these outputs is possible using the Hik-Connect smartphone app, the iVMS-...

5G technology (the fifth generation of mobile networks) is the next stage in the development of wireless communications, offering significantly higher data speeds, lower latency and the ability to support a huge number of devices simultaneously. The key element that distinguishes 5G from previous generations (2G, 3G, 4G LTE) is the frequency ranges in which this network can operate....

The question of how to verify the correctness of a fibre optic installation comes up very often. Installers acquire the basic equipment for verification - an optical power meter and a light source - but are unsure how to correctly perform the measurement itself and, above all, how to interpret the results....
