TelTek is a new generation privacy sweeping device that will plug into your phone line and tell you in an instant if there is any eavesdropping, recording, wiretapping or extension line pickups. It continually checks your phone line and instantly informs you when you have a potential threat to your telephone privacy. TelTek sends a signal from your telephone location all the way to your junction exchange and reports back any potential threats. It detects the special charcter of your phone line and then instantly alerts you if something changes. When detection of eavesdropping is uncovered, an LED light goes one and an alarm will go off if you want it to.
