The Wireless PC Lock is billed as a convenient aid for protecting personal details and programs when away from the PC or laptop. A receiver is connected via a USB port to the computer while a transmitter is placed upon the person. Should the transmitter and receiver be more than two metres apart then the PC will lock.
PC PhoneHome differs from the other tracking solutions in that it does not require an annual subscription and is totally self sufficient, reporting not to a tracking center but to the laptop owner. This reduces the cost and ensures a user can pass information onto the law enforcement officer as quickly as it is received.
