Abstract: A support column structure includes a vertical support column, a horizontal support column, and/or an oblique support column, which are made of hollow fiber-reinforced resin members having substantially rectangular cross sections. The support column structure further includes a plurality of S-shaped trough fixing support members. Each of the S-shaped trough fixing support members includes an inverted U-shaped first fixing portion and a normal U-shaped second fixing portion, which are joined with each other. By hooking and fixing the inverted U-shaped first fixing portions onto the horizontal support column or the oblique support column, a trough can be placed on the normal U-shaped second fixing portions, thereby obtaining a trough fixing support structure. The present invention can also provide a direction changing structure that includes the trough fixing support structure and various types of angle members.

Abstract: A video camera and computer system for detecting events comprising: a processor in communication with a plurality of sensors and a camera over a communications network. The processor receives multiple data streams from the sensors, analyses the received data streams to detect an event and sends a trigger to the camera to capture video footage when an event is detected. Upon an event or alert, the processor: generates an event description associated with the detected event based on the data streams or the alert from the camera, links the generated description with an identifier of the captured video footage associated with the event, and stores the linked description and identifier to facilitate searching and retrieval of the captured video footage associated with the detected event.
