Abstract
A computer-implemented method comprises detecting, with a presence detector such as a radar device, a presence of a person at a location such as an ATM vestibule. In response thereto, a timer is initiated. After initiating the timer, a portal sensor is used to detect a change in a status of a portal permitting access to the location. In response thereto, the timer is adjusted (for example the timer is reset). Thus, multiple consecutive normal usages of the vestibule do not unnecessarily trigger an alarm.
Claims20
A computer-implemented method comprising:
- detecting a presence of a person at a location;
- in response thereto, initiating a timer;
- after initiating the timer, detecting a change in a status of a portal permitting access to the location;
- and
- in response thereto, adjusting the timer.
A system comprising:
- a timer;
- a presence detector configured to detect a presence of a person at a location;
- a portal permitting access to the location;
- a portal sensor configured to detect a change in a status of the portal;
- and
- one or more processors communicative with memory having stored thereon computer program code configured when executed by the one or more processors to cause the one or more processors to perform a method comprising:
- detecting with the presence detector a presence of a person at the location;
- in response thereto, initiating the timer;
- after initiating the timer, detecting with the portal sensor a change in the status of the portal;
- and
- in response thereto, adjusting the timer.
A computer-readable medium having stored thereon computer program code configured when executed by one or more processors to cause the one or more processors to perform a method comprising:
- detecting a presence of a person at a location;
- in response thereto, initiating a timer;
- after initiating the timer, detecting a change in a status of a portal permitting access to the location;
- and
- in response thereto, adjusting the timer.
