Make reports on a telephone that features a built-in PIR motion sensor. If an intruder is detected within a 30 ft. range, TeleSpy calls a preset telephone number and allows you to listen in to the premises.
Now, what a cool concept. If this phone was positioned in a certain way and programmed with a friend, relatives or even health care professionals number, all someone would need to do is get in front of the phone for it to call. Kindof like a ‘personalised’ ‘Call Direct‘ service only without having to push a button.
