How does antitheft laptop software works?
After installing the location tracking software it will automatically start whenever you boot your computer. In some cases when someone attempts to steal your laptop either the power cord or a USB flash drive will get disconnected from the laptop and this will trigger a loud siren. The alarm can only be stopped when you unlock the laptop by entering your password, you can normally configure the alarm sound and include a recorded voice with a theft warning.
Other anti mobile device theft software does not have an alarm and it will attempt to connect to the Internet and send out its location to a central server together with screenshots instead, the software will have learn the laptop location by using GPS if present or the IP the laptop is using, with these details the police should be able to get a search warrant for that location.
Whatever solution you choose to protect your computer from theft, remember that this is a last resort solution, security is comprised of a multi layered approach, you should not rely on location tracking software to protect your data, use it in conjunction with physical security and encryption.
