Active Displays in Secret Surveillance
Authors: Okhaifoh JE, Uzedhe GO
There is a proliferation of electronic display boards for dissemination of information and close circuit television (CCTV) for security surveillance in our society. Hence, this paper presents the use of electronic active display board for secret surveillance in the public. Public displays used for signs, textual and/or pictorial information are usually passive. The information changes from time to time without feedback from the environment in which they are installed. The system presented here feedbacks happenings from the environment through video surveillance capability for security and monitoring while displaying remotely updated information to the public using GSM technology. This work was realized using LED matrix array, an A7 SIM card module, a PIC16F877A microcontroller and CX901 camera module. The CX901 camera module is used for surveillance, and the video data is stored in the SD card which is made accessible using a Universal Serial Bus (USB). Test result from the system showed that active display functions can be extended to serve as surveillance tools in public places for feedback information replacement for CCTV camera systems that are easily noticeable.
