The present invention relates to a piece of street furniture comprising a structure incorporating a display or advertising unit (7) and a multi-channel closed circuit television security system. The system includes video cameras (CAM1 . . . . CAMN) located in a camera housing (4) above the display unit (7), and connected to two or more video tape recorders (VCR 1 . . . VCRN) located in a base storage unit (10) below the display unit (7). The video recorders (VCR) are interconnected, and connected to the outputs of the cameras (CAM), by circuitry associated with switching means (14) which is operable, when one recorder is recording the camera outputs and reaches a predetermined capacity, to cause the other recorder to commence recording the camera outputs, and vice versa. The camera outputs are therefore recorded by the recorders in turn, in a continuous loop. |
