Method and system for controlling a security system using near field communication

Abstract

A security system control system using a host object with a near field communication device and a target object with a near field communication device. The target object broadcasts a carrier signal to the host object. Using the near field communication device, the host object modulated identification information on the carrier signal and broadcasts the modulated signal. The target object demodulates the signal to determine if a user associated with the identification information is authorized to perform the intended control function. The target object determines the intended control function based upon a detection criterion. The target object causes the intended control function to be performed if the associated user is authorized to control the intended control function such as to arm or disarm the security system. The identification information can expired after a predetermined period of time. The target object updates the identification information after expiration.

Description

technical field [0001] The present invention generally relates to security systems and communication systems. More particularly, the present invention relates to controlling a security system with a remote object by transmitting radio frequency signals to a target device including a receiver and a transmitter capable of receiving and transmitting radio frequency signals. Background technique [0002] Security systems in both residential and commercial environments are well known and commonplace as people seek to protect themselves and their belongings. Security systems include any life, safety and property protection systems. Security devices including user interface keypads, control panels, and multiple sensors are installed in residential or commercial buildings. Both the installer and the security device owner can use the user interface keypad to control, configure, and manage the security device. Such control functions include arming the security device when leaving t...

Problems solved by technology

In addition, the security device generally only provides a small amount of time to enter the disarming passcode. The user is in a hurry when entering the passcode, and as a result, an error occurs when entering the passcode, resulting in false alarms.

Also, if the user is carrying something, it may be difficult for the user to enter the passcode

Additionally, because the remote transmitter operates on VHF and UHF frequencies and operates in such a range that the transmitted information could be overheard by a malicious eavesdropper using a "code grabbing" device
