The Design and Implementation of a guard against theft and alarm system with embedded telephone access and KEELOQ technique

In order to solve the problem of supervision, guard against theft and alarm for family and community, a guard against theft and alarm system is studied via telephone access, multiple access technique and KEELOQ technique. This system can carry out site monitoring: when catch the exceptional case, the system will alarm, meanwhile, the system will collect and record the spot picture, and deliver the information to the guarding against theft and control system in community server. This system still has some ways including network and cellular phone to notice the owner to look into the spot and alarm tracking record over long distances. This system has strong anti-interference ability, high performance and low dependence on hardware.
