Power over Ethernet (PoE) is a well-established technology used to power network devices through data cables. Ethernet over Power (EoP), however, works differently. Developed by Essex-based ClearView Communications, EoP allows IP security networks to run over existing mains power cables, helping sites connect security equipment without the need for extensive new data cabling.
This approach is particularly useful where installing new signal cables would be difficult, disruptive or expensive. It can also help when security systems need to be deployed quickly and suitable power cabling is already in place.
ClearView developed EoP to support a range of IP-based security systems, including CCTV, access control, ANPR, intercoms and public address systems.
Applications
Local Authority CCTV
Douglas Borough Council, the largest local authority in the Isle of Man, wanted to extend CCTV coverage to North Quay in Douglas, the island’s capital and political centre. The area was undergoing regeneration and becoming a popular entertainment and leisure destination, making public safety and antisocial behaviour prevention a priority.
Although mains power cabling had already been designed and installed as part of the scheme, the decision to add CCTV came at a later stage, once the ducting was already in place. Installing new signal cables would have added disruption, complexity and cost.
ClearView used Ethernet over Power to digitise the local electrical infrastructure, allowing internet connectivity, video footage and telemetry data to run over the existing mains cable network. Each Viseum Intelligent Moving Camera was assigned an IP address, with images and control data transmitted back to the main control room in Douglas.
Four intelligent moving cameras were installed along the quayside, with monitoring from a central control room and digital recording available both at the cameras and in the control room.
Council Leader David Christian, Chairman of the Policy and Resources Committee, said: “With the regeneration of the North Quay, and the area rapidly becoming a major entertainment and leisure zone for the capital, extending CCTV coverage to the locality was a priority. The Council fully supports the use of CCTV as it helps protect the public, acts as a deterrent to antisocial behaviour, and footage can be used in Court to bring criminals to justice. We have also been encouraged to learn that our partners, the police, have indicated they would be in favour of monitoring the CCTV coverage live at weekends. Each intelligent moving camera gave the coverage of about 20 of the older CCTV units.”
Listed Building Access Control
A large public school with boarding facilities wanted to improve access security across both its residential and teaching buildings.
The project presented two major challenges. The accommodation buildings were not connected to the school’s computer network, and many of the buildings were listed, with extensive internal wood panelling. Running new cables would have been difficult, time-consuming and expensive.
ClearView proposed an IP-based access control system using Ethernet over Power. Each door controller could communicate with the central administration server through the existing mains power infrastructure, meaning only a mains power spur was required at each door.
Caravan Park CCTV and Public Address
A local authority operating a caravan storage facility had experienced several break-ins, resulting in theft and damage to parked mobile homes. The council needed to improve security at the remote, unmanned site quickly and cost-effectively.
The approved solution included lighting-column mounted PTZ cameras and loudspeakers, allowing operators at the council’s remote control centre to view activity and communicate with intruders. However, the existing ducting only carried mains power to the floodlights and had no capacity for new signal cables. Running new cabling across the 400-metre site would have required expensive civil works.
ClearView designed a remote monitoring solution using an IP link to the council’s central monitoring centre. IP pan, tilt and zoom cameras, along with IP loudspeakers, were mounted on the existing lighting columns. Video, telemetry and audio signals were then carried over the mains power cables using Ethernet over Power, back to a local hub on site before being transmitted to the control room.
The client was pleased with the design because it avoided costly civil engineering work, reduced disruption and shortened the installation programme.
Gatehouse ANPR
Commercial site entrances often need technology to help manage vehicles, visitors and staff access. This can include CCTV, ANPR, access control and intercom systems. However, gatehouses are often built before these systems are required, leaving them without suitable network infrastructure.
At a logistics depot in East Anglia, the client needed ANPR to operate alongside vehicle barriers at the main entrance. The gatehouse was around 200 metres from the depot office and had mains power, but no route for new signal cabling. A wireless link was also unsuitable because there was no clear line of sight between the gatehouse and the office.
ClearView’s Ethernet over Power system was used to carry ANPR, CCTV and intercom data back to the depot office. Staff could then view entrance activity, control barriers, access ANPR information and communicate with drivers through ClearView’s IP intercom system.
Ethernet over Power can provide a practical, lower-cost way to create an IP network for security applications where traditional cabling is difficult. Once the EoP network is in place, it can also support additional services such as wireless access points, VoIP telephony, room control and asset protection.
If your site needs CCTV, ANPR, access control or intercom connectivity but new cabling would be difficult or costly, ClearView can help design a practical IP security solution.
