A High End Building Automation and Online Video Surveillance Security System

چکیده
This paper deals with the design and implementation of a building automation and security system which facilitates a healthy, flexible, comfortable and a secure environment to the residents. The design incorporates a SIRC (Sony Infrared Remote Control) protocol based infrared remote controller for the wireless operation and control of electrical appliances. Alternatively, the appliances are monitored and controlled via a laptop using a GUI (Graphical User Interface) application built in C#. Apart from automation, this paper also focuses on indoor security. Multiple PIR (Pyroelectric Infrared) sensors are placed within the area under surveillance to detect any intruder. A web camera used to record the video footage is mounted on the shaft of a servo motor to enable angular motion. Corresponding to which sensor has detected the motion; the ARM7 LPC2148 microcontroller provides appropriate PWM pulses to drive the servo motor, thus adjusting the position and orientation of the camera precisely. OpenCV libraries are used to record a video feed of 5 seconds at 30 frames per second (fps). Video frames are embedded with date and time stamp. The recorded video is compressed, saved to predefined directory (for backup) and also uploaded to specific remote location over the internet using Google drive for instant access. The entire security system is automatic and does not need any human intervention. Keywords—Automation, OpenCV, Remote control, Security, SIRC, Web camera

Nowadays automated early warning systems are essential in human life. One of these systems is fire detection which plays an important role in surveillance and security systems because the fire can spread quickly and cause great damage to an area. Traditional fire detection methods usually are based on smoke and temperature detectors (sensors). These methods cannot work properly in large space a...
متن کاملPedestrians Tracking in a Camera Network
With the increase of the number of cameras installed across a video surveillance network, the ability of security staffs to attentively scan all the video feeds actually decreases. Therefore, the need for an intelligent system that operates as a tracking system is vital for security personnel to do their jobs well. Tracking people as they move through a camera network with non-overlapping field...
