Abstract: A security system includes a camera that captures an image of a monitoring area, a recorder that stores the captured image which is captured by the camera, a sensor that detects a matter in the monitoring area, a video monitoring and display device that causes a monitor to display the captured image of the monitoring area from the camera or the recorder, and a BLE reception device that detects a signal from a BLE transmission terminal which is installed or maintained by a guard who patrols the monitoring area. In a case where the matter is detected in the monitoring area, the video monitoring and display device extracts the captured images of the suspect or the guard, chronologically arranges the captured images, and displays the captured images on the monitor.
Abstract: A pneumatic tire (10) according to the present invention includes blocks (100) arranged adjacent to each other in a tread surface view, each of the blocks (100) having a wheel tread contacted with a road surface. A circumferential edge (100f) of the block (100) is defined against an adjacent block (100B) adjacent to the block (100A) by a sipe (200). An inner side groove (400) is formed at an inner side in a tire radial direction of the sipe (200). At least a part of the inner side groove (400) is communicated with the sipe (200). The circumferential edge (100f) of the block (100A) is defined against the adjacent block (100B) by the inner side groove (400).
