Senstar Company finds this method of security is one of its favourite models for security at Tier-1 transmission sub-stations

Senstar has been helping a major US electrical utility company protect its sites for many years, starting with the FlexZone ranging fence-mounted intrusion detection system and now the Senstar LM100 hybrid perimeter intrusion detection and intelligent lighting system.

Since 2013, FlexZone has been installed at 18 of the company’s Tier-1 transmission substations. FlexZone is part of multi-layered security solution at these sites which also include cameras, video analytics, public address systems and LED perimeter lighting.

The sites are remotely monitored by security personnel at a central monitoring station. One of the reasons the utility company selected FlexZone was because of its easy integration with other systems. In this case, it is integrated with the lighting systems, so when an intrusion alarm is triggered by FlexZone, additional lighting turns on and a security procedure is activated.

FlexZone has been very successful and ‘‘is one of our Command Centre operators’ favourite security modules’’ and it works well with the lighting system to deter and detect intrusion attempts.

The Senstar LM100 combines deterrence and detection in one cutting-edge product. Added to Senstar’s product portfolio in 2017, the Senstar LM100 is the first-of-its kind in the market.

When the utility company was first introduced to the Senstar LM100, they did a cost analysis and determined they could save US$80,000 per site. The savings are a result of the reduction of electrical requirements, conduit, grounding, and associated labour, as well as the removal of certain equipment from project scope that are required for the two-system integration.

“The LM100 combines all of the functions that two systems provide and it saves us a lot of money,” said the utility company’s security administrator “It is also simpler to integrate and has better functionality.” The Senstar LM100’s perimeter LED-based lighting acts as an initial deterrent. If an intruder persists and an attempt to cut, climb or otherwise break through the fence is detected, the closest luminaire begins to strobe and an alert is sent via a security management system. The intruder knows immediately they have been detected and that their exact location is known by security and others in the vicinity.

The LM100’s high colour rendering (CRI) index maximises camera performance, providing clear images of the intrusion attempt so security personnel at the monitoring station can quickly assess the situation and initiate an appropriate response.

“If someone is determined to get into a site, a fancy fence won’t stop them,” said the security administrator. “Why would I spend $1 million on a 10-foot fence that someone can climb over with a 12-foot ladder?”

While others in the utility industry simply install taller fences in the hopes of preventing crime such as theft of copper wire and tools, the security administrator has a different approach. He focuses on adding multiple layers of security to his eight-foot perimeter fences to provide multiple means to detect intrusions, provide context, and respond appropriately.

“More layers, more redundancy,” he said.

Working with Senstar Since standardising on Senstar, the utility company can send its site layout to its system integrator and the process unfolds with few issues. “It’s been incredibly easy,” said the security administrator.
