ETSI has published TS 105 176-2, a new specification enabling energy-efficient transitions from legacy analog video surveillance to IP systems by transmitting both power and data over existing coaxial cable infrastructures. This standard ensures interoperability among IP cameras, switches, displays, and audio devices, allowing network expansion without the need for new cabling from the head end. The technology leverages the robust HomePlug AV family of standards to support long-distance transmission, a solution already deployed by RATP on Paris Metro Line 14 to enhance safety and access control. By reusing existing coaxial infrastructure, the specification reduces replacement costs and ecological impact while delivering high-quality video surveillance capabilities.
