Sounding the Alarm
For those sadly inevitable occasions when the deterrents do not work, it is worth considering some of the many security gadgets and alarms on the market.
For example, some alarms work in conjunction with the laptop cable and are set off if the cable is broken. Another option is a two-way wireless alarm that, when movement is detected, checks whether your key-chain remote is nearby; if it is not, it alerts you and you have the option to set off a very loud alarm on your laptop.
Some alarms also work by setting up a security perimeter for the laptop. If the laptop moves outside that perimeter, an alarm goes off and disables the computer, locking security keys and rendering the laptop useless to the thief.
If your laptop is stolen despite these precautions, you still might be able to find it using the latest technologies. A number of tracking systems are available that can determine your stolen laptop's location. These systems usually use GPS or the cellphone network to track its location. Some of these tracking systems (such as the StealthSignal XTool Computer Tracker) also enable you to delete files remotely, to prevent misuse of files.
In case all or any of these methods fails, ensure that your laptop is fully insured.
