Lowjack

This word was used in the mid-late 1980’s and 1990’s, and was used to describe non-consensual inconspicuous tracking and surveillance, usually referring to electronic means, like low powered RF trackers or transmitter bugs.
Low: unbeknownst to the trackee. Jack: derived from hi-jack.
It is where the concept for the movie “Freejack” came from, and the name of the brand for anti-theft device for cars originated.
