Researchers at the University of Queensland have developed an industrially compatible method to produce lead-free perovskite photovoltaic cells for indoor lighting, eliminating the need for toxic lead and hazardous solvents that have previously limited the commercialisation of this technology. The team's key achievement was the development of a vapour phase evaporation process that enables the formation of high quality lead-free halide perovskites with a controlled intermediate phase, significa...

In optical fibre installation technology, there can be cables containing fibres in different standards. In LAN, CCTV, automation or FTTH installations, one encounters fibres in the G.652.D, G.657.A1 or G.657.A2 standard. The G.652.D standard has been used in telecommunications for over 20 years. The G.657.A fibre group, due to its better mechanical capabilities (smaller minimum bending radius), was originally intended to be used for last mile sections in FTTH networks. The popularity of cables ...

Multiswitches of the SIGNAL PROwww.dipol.com.pl/7025.htm?attr-1796[1]=30119*** are devices designed for distribution of satellite and terrestrial signals in SMATV systems. For their proper installation dedicated mounts are used, and one of them is UCH PRO 1 R69985. This bracket enables quick, stable and orderly mounting of two multiswitches in telecommunication cabinets, as well as on flat surfaces in Continue reading

The HiWatch series by Hikvision is a cost-effective IP surveillance solution designed for simple, reliable installations in homes, small businesses, offices or service outlets. The devices in this line, both cameras and

In situations where the DVR is to be viewed and controlled from a remote room (e.g. surveillance centre), there is a need to transmit HDMI and USB signals. In cases where the cable distance does not exceed 100 m, the H3613 converters can be used and connected by means of an ordinary CAT 5e twisted-pair cable....
