With a standard personal emergency response system,
the end user is limited by the location of the base station
because they have to be within "range" to hear the central
station talking to them.
If they are too far away, they cannot
hear, or more importantly, explain the emergency!
LifeSentry will allow your customer to communicate
their message instantly and efficiently from within
many hundreds of feet of their base station.
The system should cover an average American home and
well into the front, back and side yards.
