ELV solutions are becoming increasingly popular in the industry as they enable businesses to operate seamlessly and efficiently. ELV means extra low voltage systems. The systems that operate at low voltage are often termed "ELV" systems. An ELV system established in a residential or commercial building ensures better control and security and reduces the need for multiple connections and cables in a building. The system includes IT networks, CCTV, voice and video intercom, door access control, lighting control, audio-visual systems, lift access control, etc. Designing and implementing perfect ELV systems requires expertise.
