Abstract:
LoJack, an antitheft device that made its premiere in the Bay Area in late March, may help sooth any worries people have about their cars being irretrievably stolen.
Only police cars equipped with LoJack scanners can pick up a stolen car signal. LoJack gave 300 to 400 of these scanners free to police in six Bay Area counties.
LoJack-equipped cars are far more likely to be recovered by police, the company says. Nearly 90 percent of cars with LoJack are recovered after being stolen versus 65 percent of cars without, the company says.

The two San Francisco police officers zeroed in on the signal from a stolen Saab that, unbeknownst to the driver, was equipped with a homing beacon.
Within 15 minutes, the officers, who were on a routine patrol through the Potrero Hill neighborhood, had tracked their quarry to the Financial District, where they arrested one of two men in the Saab on suspicion of auto theft.
LoJack, an antitheft device that made its premiere in the Bay Area in late March, may help sooth any worries people have about their cars being irretrievably stolen.
The technology allows police to locate stolen cars with the help of a homing beacon and perhaps catch the thieves.
"We think this technology is going to help us recover cars more quickly," said Al Tong, an officer with the San Francisco Police Department's electronic tracking unit. "Finding stolen cars can be difficult if all you are relying on is a list of license plate numbers."
LoJack has been available in other metropolitan areas for up to 14 years. It is sold in 18 U.S. cities, including Los Angeles and San Diego in California.
Guided by LoJack, police in Southern California have found more than 100 "chop shops," places where thieves strip cars for parts to resell. They have also discovered stolen luxury cars inside metal containers that were destined to be shipped overseas.
Since its premiere, San Francisco police have recovered two cars using LoJack.
This is how it works: LoJack's security system relies on a transmitter the size of a chalkboard eraser that technicians install in one of up to 30 places on a car. The company has kept those locations secret to keep thieves from disarming the system.
The transmitter is activated only when the police turn it on remotely by radio after the car has been reported stolen.
Only police cars equipped with LoJack scanners can pick up a stolen car signal. LoJack gave 300 to 400 of these scanners free to police in six Bay Area counties.
When a police scanner picks up a signal, it displays a code unique to that car, allowing the officer to get detailed information on the vehicle such as its make, license number and color. The scanner also beeps louder when officers get closer to their target and shows arrows indicating direction.
Officers normally have the scanners operating while on routine patrol. If the scanner happens to beep, they stop what they are doing and begin the hunt.
LoJack-equipped cars are far more likely to be recovered by police, the company says. Nearly 90 percent of cars with LoJack are recovered after being stolen versus 65 percent of cars without, the company says.
Ian Ayres, a law professor at Yale University who has studied LoJack, said the device is effective in reducing crime. Car thefts, he said, decline by 40 percent in central cities and 13 percent in metropolitan areas after LoJack is introduced.
"If you're stealing 100 cars a year or you're a chop shop dealing with 1,000 cars a year, you have dramatically increased the chance that you'll be exposed," Ayres said.
Ayres added that LoJack is far more effective at reducing overall crime than other popular antitheft devices. He said thieves who encounter car alarms and steering-wheel clubs simply look for a different, less defended cars, while thieves in cities where LoJack is sold seem to stop stealing or get sent to prison.
LoJack is sold for $595 through new-car dealers or directly from the manufacturer. Customers whose stolen car is not recovered within 24 hours get a full refund.
About 100 Bay Area car dealers are authorized to sell LoJack. LoJack would not disclose how many units it has sold in the Bay Area.
John Raber, vice president of LoJack's West Coast division, said many of his company's clients own cars worth between $20,000 and $25,000. He described his clients as having modest enough incomes that "they can't afford to have their car stolen."
LoJack's main competitor, Teletrac, offers an antitheft tracking device that operates much like a global positioning unit, though it is not sold in the Bay Area. Several automakers, including Lincoln and General Motors, offer similar systems in some new cars.
In most cities, the scanners have a range of between 3 and 5 miles. However, the range is only about a mile or two in some parts of San Francisco because of the hilly terrain, according to Tong, the San Francisco police officer.
Tong added that tracking a stolen car takes skill because signals can be deceptive. They bounce from buildings, metal and water, he said.
"San Francisco is probably one of the most difficult cities to track in," Tong said.
Of course, LoJack is not the perfect solution to car-theft problems. The tracking technology alone does not prevent a car from being stolen in the first place.
Thieves can also try take the car beyond LoJack's range -- to the Central Valley, for example -- before the owner knows it's gone. The tracking technology works only in a relatively small part of the nation, giving thieves a lot of territory in which to elude police scanners.
Another consideration is that buying LoJack does not make economic sense for everyone, according to Ayres, the Yale professor.
The technology is a good investment if the consumer's insurance company gives a substantial discount, Ayres said. 21st Century Insurance Co., for example, gives a 15 percent discount on premiums to car owners who have LoJack, Teletrac and antitheft systems offered by the car manufacturers.
However, Ayres said buying LoJack is probably a bad deal for drivers whose insurance companies do not offer cheaper rates, as is the case with State Farm. Such drivers get no financial benefit for buying LoJack because they are reimbursed if their car is stolen regardless of whether it is recovered.
Yet some people may be looking for a payoff that has nothing to do with money, Ayres said. Some, he said, may simply want "the personal pleasure of catching a thief."

HOW LOJACK WORKS
LoJack's security system is designed to help police track down stolen cars that are equipped with a homing device. Here's how it works:
1 Car is stolen ... and driven away from the scene
2 Owner calls police
Best-case scenario: Owner notices the car is gone shortly after it's stolen and notifies police immediately.
Worst-case scenario: Owner is at work and doesn't know car is stolen for several hours. Police don't know to turn on LoJack until car is reported stolen.
3 Police turn on LoJack in stolen car The device emits a signal that can be detected if it's within 1 to 5 miles of a police cruiser with a LoJack scanner.
4 Law enforcement looks for car
Best-case scenario: LoJack says that 300 to 400 police cars in the Bay Area are equipped with a LoJack scanner. When the scanner detects a stolen car, it shows a code to the officer that is then matched up with the vehicle information (color, year, make, etc.).
Worst-case scenario: No LoJack-equipped cruiser is in the area of the stolen car.
5 Stolen car is recovered or not
Best-case scenario: Police officer locates stolen car by following tracking data from LoJack scanner and returns car to owner.
Worst-case scenario: Car is driven well beyond range of any LoJack- equipped cruiser, or car is driven to a "chop shop" where it's dismantled. Owner gets $595 refund from LoJack.

Stvarno bi se mogle reći da se izraz lojack,lojacking i slično udomaćio kao pojam koji se odnosi na praćenje i nalaenje stvari, pa čak i osoba kako se ispod vidi:
like \'lojack\' for children: wireless location services in an age of endangered kids
As high-profile kidnappings put the nation\'s parents on edge, new GPS-based \'personal locator devices\' provide eyes in the sky when it matters most
All the rage: panic buttons for preschoolers
By Rick Mathieson
U tom slučaju bolje je pisati lojack nego LoJack jer je prvi izvedenica a drugi izvorni pojam.
