Abstract
Systems and methods of adjusting a pre-alarm time are provided, including detecting, by a sensor, an entry into a building by a person and generating detection data according to the detected entry. A processor communicatively coupled to the sensor adjusts a pre-alarm time according to the detection data. An alarm is output, by an alarm device communicatively coupled to at least the processor, according to the detection data and the adjusted pre-alarm time.
Claims40
A security system comprising:
- a sensor to detect an entry into a building by a person, and generate detection data according to the detected entry;
- a processor communicatively coupled to the sensor to receive the detection data, the processor to estimate a threat level based on the detection data and a security system operating state, and to adjust a pre-alarm time according to the estimated threat level;
- and
- an alarm device, communicatively coupled to at least the processor, that outputs an alarm according to the detection data and the threat level.
