Low Voltage and Communication Systems
Extra Low Voltage (ELV) refers to electrical systems that operate at low enough voltages — typically 50V AC or below — to pose minimal risk of electric shock. In modern buildings, “ELV” is the umbrella term for the low-voltage networks behind security, communication and automation, kept separate from the main electrical supply. A specialist ELV contractor designs, installs, integrates and maintains these systems so they work together on one platform.
Common ELV systems include: CCTV and surveillance, access control, public address (PA), audio-visual (AV), building automation and control, environment monitoring, and structured data and communication cabling.

An ELV (Extra Low Voltage) system is any building system running at roughly 50V AC or below — such as CCTV, access control, PA and data cabling — designed for safety and integrated under one platform.
Typical ELV systems include surveillance and CCTV, access control, public address, audio-visual, building automation, environment monitoring, and low-voltage communication cabling.
An ELV contractor designs, supplies, installs, integrates and maintains a building’s low-voltage systems so security, communication and automation work together reliably.
No — RISB integrates CCTV, access control and the other ELV systems on a single platform, which simplifies management and avoids gaps between separately installed systems.
