Mobile Phone Patent Description
BACKGROUND OF THE INVENTION
I. Field of the Invention
This invention relates generally to an antitheft system with signals
transmitted by mobile phone network and, more specifically, to an
antitheft system with signals transmitted by mobile phone network
that transmits audio and video signals to the carrying mobile phone
of the house owners on remote sites with another mobile phone wirelessly.
II. Description of the Prior Art
Heretofore, it is known that a antitheft system is made of electronic
or mechanical sensors installed on window and door entrances, these
sensors detect vibration or motion of objects to trigger alarm signals
for antitheft effect.
Another type of antitheft system applies laser beam or regular
light detectors; when light beam is blocked, the alarm system is
triggered for antitheft purpose. The laser beam or regular light
detectors must be installed in pairs that might causes troublesome
in wiring; in order to achieve better effect, multiple reflecting
mirrors have to be installed for multiple reflecting paths to achieve
denser beam net to reduce the numbers of the light beam generators
and light beam detectors. The cost to apply laser beam as light
source is very expensive, therefore this method only applies in
strictly security requirement.
Home antitheft systems are usually link to central monitoring center
or police station monitoring system, they have to be connected together
with cables and wires; wiring causes inconvenience and troublesome
in connection and transmission, wiring might be very costly.
Upon burglar intrusion, only central monitoring center or police
station monitoring system can aware right away, the house owners
might not know immediately. Once there are visitors and the house
owner is not at home, house owner will not aware at all, that causes
visitors' confusion and inconvenience.
Another known prior art applies existing telephone network for
remote monitor and auto alarm system to transmit image and alarm
signals, however telephone wire transmission can only apply to certain
locations, such as police station, security center, house owners'
offices. Only upon burglar intrusion, police station, security center
will send people and check the abnormal situation the sites; such
scheme cannot achieve two-way communication. To the house owners
the two-way monitoring system only applies on the locations with
telephone wiring, two-way monitoring system cannot apply to the
spots without telephone wiring, that causes blind spots. Another
disadvantage of the telephone wiring system is the wires would be
damaged easily accidentally or purposely.
