SECURITY DEVICE, SECURITY SYSTEM AND METHOD

摘要

A security device and method receives gas pressure signals from a pair of gas pressure sensors, one set at the inside and the other at the outside of a door or a window. Gas pressure values for the signals (of the indoor and outdoor environments) are obtained and a camera, working in the same location as the pair of sensors, is controlled to capture photos or videos when it is determined that the gas pressure values of both sensors have changed and magnitude of the changes are both within a preset gas pressure range. Photos and videos are captured by the camera and transmitted to at least one validated contact according to preset contact information.

主权项

1. A security device comprising:
a processor; a storage device coupled to the processor storing a preset gas pressure range and preset contact information of at least one validated contact; a short distance communication unit coupled to the processor and configured to connect to at least one pair of gas pressure sensors and at least one camera, wherein each pair of gas pressure sensors are respectively set at inside or outside of a door or a window of a house and each camera is set at the door or the window; and a long distance communication unit coupled to the processor and configured to transmit data to the at least one validated contact; wherein the processor is configured to receive gas pressure signals generated by the at least one pair of gas pressure sensors, obtain gas pressure values of indoor environment and outdoor environment according to the gas pressure signals, and control the at least one camera to capture photos or videos when determining the gas pressure values of indoor environment and outdoor environment detected by one pair of gas pressure sensors are changed and magnitudes of changes of the gas pressure values detected by the pair of gas pressure sensors are both within the preset gas pressure range; and the processor is further configured to transmit the photos and videos captured by the at least one camera to the at least one validated contact according to the preset contact information stored in the storage device.
