Vehicles, Drivers In Security Sync
A combination of long range barcode readers and proximity tags have brought together vehicles and their drivers to provide better identification at Hawaiian terminals serving a local utility.
From satellite images by NASA, the balmy Hawaiian Islands rise like turquoise stepping stones in the vast Pacific Ocean. The tiny city of Hilo appears nestled at the foot of the Mauna Loa range, and Maui blinks with a timeless charm. Kauai looms as green as Eden, invoking a laid-back atmosphere, and Oahu, the most populated island, erupts like a modern volcanic metropolis slowly encroaching the domain of the forested Nuuanu Pali peak. Miles of shoreline and bustling seaports are visible, bringing supplies and travelers to the islands.
Yet, in these higher security days, business as usual ceased. The U.S. Department of Homeland Security (DHS) has guidelines for disaster response. To govern port and vessel security, Congress enacted the Maritime Transportation Act (MTSA), which also covers the U.S. Petroleum Industry’s coastal operations. The U.S. Coast Guard conducts maritime assessments to bring everyone into MTSA federal security compliance.
One utility company scrambling to upgrade security plans is The Gas Company of Hawaii. The synthetic natural gas and liquefied propane gas producer operates four remote storage terminals and services 115,000 businesses and residences on Oahu, Hilo, Maui and Kauai. The company operates 1,000 miles of underground pipelines from central storage areas and also delivers cylinders to clients at remote locales.
After inspection, the Coast Guard identified the company’s offloading ports and terminals as a major terrorist target and required implementation of round-the-clock surveillance. Procedures for entering and exiting sites were important to effectively implement the security plan. Vehicles seeking entry and exit, as well as their drivers, needed to be authenticated.
Network integrationThe utility turned to security systems integrator Tom Keener, president and founder of Keener Technologies Inc. in Hawaii, to come up with a solution. After assessing the geographical area, he proposed an integrated network system, extending it beyond traditional installation.
“So far, no breach has happened,” said Keener. “The system has saved The Gas Company several thousand dollars a year by displacing 24/7 security guards.”
His first job was to secure each of the entry points, where a high volume of tanker trucks, work trucks, service trucks and personal vehicles moved through. He chose a BA-200 Barcode Reader, by Barcode Automation of Winter Springs, Fla., as gatekeeper. The readers integrated with other computer security systems via Wiegand 26-bit output or a RS232 serial port. The reader, which featured a barcode decal that, once attached, could not be lost, stolen or loaned, was designed to ignore barcodes printed on paper or photocopies.
Barcode labels“Every vehicle has a barcode decal attached for identification in and out of the yard,” said Keener. “Each barcode is entered into a Hirsch Electronics (Santa Ana, Calif.) Velocity database, configured by us.”
The barcode reader also featured a high scanning rate and retained an internal transaction log with the last 2,000 vehicle identification numbers, time and date. It was configured so that as a vehicle passed, the code would be checked against the internal database to see if that vehicle had access.
Keener also configured HID (Irvine, Calif.) proximity tags issued to employees, truck drivers and contractors, to satisfy a two-fold authentication rule set by the Coast Guard. The regulation required the barcode decal and matching HID card be processed at entry and exit; otherwise, access would be denied and alarms would sound, alerting the Honolulu operations center.
“The Gas Company has set a certain protocol for the operators to follow on who and when, to call the authorities in case of a breach,” said Keener.
The integrator also set up the system to respond to DHS threat levels; procedures change and they can set so-called “time zones” by using the system’s command modes to allow only designated persons into the facility. But he did not stop there.
Keener added infrared security video PTZ day/night cameras for surveillance, digital video recorders at each site, high-speed DSL communication, a private WAN to secure the network through firewalls and secured routers, database servers and a high-wattage UPS battery backup system. Upon intrusion, the PTZ camera was set to pan to the alarm zone that was violated on the fence, and alert operators as to exactly where the intrusion took place.
The system runs so smoothly, Keener reported he will install two similar systems for other clients, beginning, of course, with a well-placed barcode reader. V
