Motion sensor light, surveillance system and surveillance method
First Claim
1. A motion sensor light comprising:
- a light that remains turned on at least for a predetermined duration set in advance;
a sensor that detects movement of a moving object; and
a processor that turns on the light in a case where the movement of the moving object is detected,wherein the processor initiates measurement of lighting duration of the light in response to the lighting of the light, after then, initiates measurement of lights-out delay duration that indicates time duration for a non-detection state of the moving object from a time when the moving object is no longer detected to a time when the light is turned off in a case where the movement of the moving object is no longer detected, and acquires a set value of the lights-out delay duration according to the duration set in advance, andthe light is turned off in a case where a measured value of the lights-out delay duration exceeds the set value of the acquired lights-out delay duration, and a measured value of the lighting duration of the light exceeds the duration set in advance.

Abstract
A motion sensor light turns on a light once a motion sensor detects movement of a person. The light illuminates a monitoring area once the light is turned on. The motion sensor light initiates measurement of lighting duration of the light. After then, the motion sensor light initiates measurement of lights-out delay duration in a case where the movement of a person is no longer detected, and acquires a set value of the lights-out delay duration according to the lighting duration set in advance. The motion sensor light turns off the light in a case where a measured value of the lights-out delay duration exceeds the set value of the lights-out delay duration and a measured value of the lighting duration of the light exceeds a set value of the lighting duration.

6. A surveillance system comprising:
-
a motion sensor light and a master device which are connected to each other, wherein the master device saves each operation condition for lighting and lights-out of the motion sensor light, transmits a lighting command to the motion sensor light in a case where the operation condition for lighting is satisfied, and that transmits a lights-out command to the motion sensor light in a case where the operation condition for lights-out is satisfied; and the motion sensor light is turned on in a case where the lighting command transmitted from the master device is received or in a case where a moving object is detected in the surroundings of the motion sensor light, and is turned off in a case where the lights-out command transmitted from the master device is received and a non-detection state of the moving object continues for a certain amount of time after the moving object is no longer detected. - View Dependent Claims (7, 8, 9)

10. A monitoring method for a surveillance system in which a motion sensor light and a master device are connected to each other, comprising:
-
saving, which is carried out by the master device, each operation condition for lighting and lights-out of the motion sensor light; transmitting, which is carried out by the master device, a lighting command to the motion sensor light in a case where the operation condition for lighting is satisfied; transmitting, which is carried out by the master device, a lights-out command to the motion sensor light in a case where the operation condition for lights-out is satisfied; turning on the motion sensor light in a case where the lighting command transmitted from the master device is received or in a case where a moving object is detected in the surroundings of the motion sensor light; and turning off the motion sensor light in a case where the lights-out command transmitted from the master device is received and a non-detection state of the moving object continues for a certain amount of time after the moving object is no longer detected.
