Abstract
A system and a method for presence detection and notification. The system includes a a first unit including a first sensor and a first visual alert, and a second unit including a second sensor and a second visual alert. The first unit is constructed to send a signal to the second unit to trigger the second visual alert, when the first sensor detects a presence. The second unit is constructed to send a signal to the first unit to trigger the first visual alert, when the second sensor detects a presence. The first and second visual alerts are constructed to be triggered independently of one another.
Claims21
A system for presence detection and notification, comprising:
- a first unit comprising a first sensor and a first visual alert;
- a second unit comprising a second sensor and a second visual alert, wherein the first unit is constructed to send a signal to the second unit to trigger the second visual alert, when the first sensor detects a presence;
- two half-barrels adapted to be inserted into a peephole of a door, wherein the half-barrels have electrical connections integrated therein such that the first and second units can be mounted on opposite sides of the door and electrically connected through the peephole, and wherein the first and second units each comprise a peephole lens;
- wherein the second unit is constructed to send a signal to the first unit to trigger the first visual alert, when the second sensor detects a presence, and wherein the first and second visual alerts are constructed to be triggered independently of one another such that the first visual alert is triggered by the presence detected by the second sensor and not by the presence detected by the first sensor, and the second visual alert is triggered by the presence detected by the first sensor and not by the presence detected by the second sensor.

A system for presence detection and notification, comprising:
- a first unit attachable to a surface, the first unit comprising a first sensor, a first visual alert, a first audio alert, and a first wireless transmitter and receiver;
- a second unit attachable to a surface, the second unit comprising a second sensor, a second visual alert, a second audio alert, and a second wireless transmitter and receiver;
- wherein the first wireless transmitter is constructed to a send a signal to the second wireless receiver to trigger the second visual alert and the second audio alert, when the first detector detects a presence;
- wherein the second wireless transmitter is constructed to send a signal to the first wireless receiver to trigger the first visual alert and the first audio alert, when the second sensor detects a presence;
- wherein the system is configured such that the first and second visual alerts are triggered independently of one another, and the first and second audio alerts are triggered independently of one another such that the first visual alert and the first audio alert are triggered by the presence detected by the second sensor and not by the presence detected by the first sensor, and the second visual alert and the second audio alert are triggered by the presence detected by the first sensor and not by the presence detected by the second sensor;
- wherein the first visual alert is further adapted to blink when the first unit no longer senses signal from the second unit;
- wherein the first unit comprises a switch for a security mode in which the second visual alert is deactivated;
- and
- wherein the first unit comprises an audio switch for deactivating the first and second audio alerts.

A method for presence detection and notification, comprising:
- providing a first unit comprising a first sensor and a first visual alert, and a second unit comprising a second sensor and a second visual alert;
- installing or setting at least one of the first and second units on a surface;
- sending a signal from the first unit to the second unit when a presence is detected by the first sensor, to trigger the second visual alert;
- sending a signal from the second unit to the first unit when a presence is detected by the second sensor, to trigger the first visual alert;
- putting the system into a security mode by using a switch on the first unit, wherein, in the security mode, the second visual alert is deactivated;
- wherein the first and second visual alerts are triggered independently of one another such that the first visual alert is triggered by the presence detected by the second sensor and not by the presence detected by the first sensor, and the second visual alert is triggered by the presence detected by the first sensor and not by the presence detected by the second sensor;
- and
- wherein the first visual alert is further adapted to blink when the first unit no longer senses signal from the second unit.
