Intrusion Detection for Aluminum Protection

Integrated system helps solve Aluma's metal theft problem

HSG surveyed the situation. These were large pieces of commercial building-grade aluminum and stainless steel. These were not mere pipes and small sheets of metal. Therefore, the thieves needed a vehicle to transport them away. Each piece could run as much as $2,500 and were quite large.

In order to enter and leave the outdoor storage facility, the thieves would have to enter one of the three driveways going into and out of the facility. What they needed, HSG determined, was a robust transmitter that could be placed by each driveway that would connect back to the central control station.

Having worked with Inovonics for more than 10 years, HSG knew that it was a fitting solution to Aluma's problems. The company's wireless security products can connect to almost any security system and offer direct interfaces with many industry-leading control panels. Plus, with the availability of add-on and serial receivers, Aluma would have flexible connectivity options.

Inovonics' intrusion detection devices transmit alarms when sensing unauthorized entry or activity. It also manufactures universal transmitters that detect open windows or doors, motion detectors to warn of intruders and glass-break detectors that indicate a broken window, door, or display case.

HSG installed an outdoor PIR or motion detector on each of the three driveways and strategically throughout the yard. Inovonics-powered field sensors were used to activate the cameras reporting to a central station. This was accomplished by combining outdoor motion detectors with universal transmitters. Motion sensing events activate the universal transmitters. The Inovonics receiver then activates video cameras only when motion is detected.

In all, HSG installed the EN1210 Universal transmitters; the EN4204R four-zone add-on receivers with relay outputs for managing and monitoring the EchoStream network; and the EN5040-T High power repeater with transformer, which amplifies transmissions from any of its EchoStream transmitting devices while ignoring background noise.

Documentable ROI

The cameras, combined with the Inovonics solution, eliminated the problem of the false alarms. Aluma had a reliable solution that could protect against thieves entering and stealing its metal assets.

Besides solving the false alarm incidence rate, this wireless configuration realized three other benefits. Video storage capability was increased, network traffic was reduced and the yard had the flexibility to move battery-powered detectors to adjust coverage depending on changing needs.

In less than two months, Aluma had recouped the cost of hiring the physical security guard. Plus, it no longer experienced any theft, protected its assets, eliminated loss prevention and was able to reallocate the $10,000 monthly out-of-pocket costs for the security guard back into its bottom line. That's $120,000 annually, which was a big impact to its profitability.

Aluma is looking at other ways to deploy the wireless solutions. Recently, it added security pendants to the cleaning crew who comes in on Saturdays so they could easily arm and disarm the sensors without causing any alarms to go off.

In addition, Aluma now has the flexibility of adding more motion detectors, transmitters and receivers easily and without much additional cost. They can move the existing devices wherever they are needed if they should reconfigure the layout of their storage yard.
