COLLABORATED ALARMING GENERATION SYSTEM FOR CCTV CAMERA COVERING

摘要

PURPOSE: An integrated type alarm generation is provided to generate an alarm in a control center by transmitting after detecting spray of spray pigment to a camera. CONSTITUTION: A plurality of optical sensors(2) are arranged in an external case while being spaced apart with each other. A alarm generator(10) is connected to a CCTV cable(5) and the optical sensors, receives an optical intensity value from the optical sensors, compares the received optical intensity value with the reference value and transmits an abnormality situation occurrence signal if difference greater than a specific level. An alarm controller is installed in the control center, is connected to the CCTV cable and generates a visual and auditory alarm signal according to the received signal if the abnormality situation occurrence signal is received form the alarm generator.
