ABSTRACT In this paper we design and implement a home embedded surveillance system with ultra-low alert power. Traditional surveillance systems suffer from an unnecessary waste of power and the shortcomings of memory conditions in the absence of invasion. In this design we use Pyroelectric Infrared sensors (PIR) and pressure sensors as the alert group in windows and doors where an intruder must pass through. These low-power alert sensors wake up the MCU (Micro Controller Unit) which has power management for the ultrasonic sensors and PIR sensors indoors. This state transition method saves a large number of sensors required for the alert power. We also use the Majority Voting Mechanism (MVM) to manage the sensor groups to enhance the probability of multiple sensors sensing. After the MCU sends the sensor signals to the embedded system, the program starts the Web camera. Our sensing experiment shows that we reduce the system's power consumption.

    ABSTRACT: In this paper we design and implement an embedded surveillance system by use of ultrasonic signal coding of ultrasonic sensors with multiple pyroelectric infrared sensors (PIR) to detect an intruder in a home or a storehouse. If the sensors detect any trespasser, then the camera will captured the image. After that the image will compared with the database. If it is not similar then that image will be send to the number which was stored in the MMS modem as MMS. The PIR sensors are placed on the ceiling, and the ultrasonic sensor modules are placed in a line direction may consist of a transmitter and a receiver. Ultrasonic coding signal is used to reduce high miss rate. Majority Voting Mechanism (MVM) is used to manage both ultrasonic and PIR sensors. In addition fire and smoke sensors are used to detect the fire inside the home. If the sensor detects gas or smoke it will automatically switch on the motor.

    ABSTRACT: This paper presents a way to reduce the standby power consumption of a personal computer (PC) monitor in sleep status. Although a PC monitor enters sleep by means of the power management of the operating system (OS) after a preset idle time and awakens when the keyboard is hit or the mouse is moved, the monitor still consumes 0.3-1 W power in sleep status. This design features a socket to plug-in the PC monitor, which consumes 0.003 W in sleep status and is not only easy to set up but also inexpensive. This socket supplies the monitor with power when the user appears; when the user leaves it turns the monitor off, and the electric power is cut off to reduce the standby power. A micro control unit (MCU) receives signals from an infrared (IR) sensor module which detects the user approaching the monitor. The MCU controls the solid state relay (SSR) On/Off when used as a switch for cutting off the standby power.

    ABSTRACT: In this paper we present a design using an ultrasound module to reduce the standby power consumption of a personal computer (PC) monitor. Although a PC monitor enters standby status by means of the power management of the operating system (OS) after a preset idle time and awakens when the keyboard is hit or the mouse is moved, this way of entering standby status is not efficient for the monitor which still consumes 0.3-1 W of power in standby status. Our design features a socket to plug-in the PC monitor, which enters standby status more efficiently, consuming 0.008 W. This socket supplies the monitor with power when a user is detected by the ultrasound module; when the user leaves it turns the monitor off without using an idle timer, and the electric power is cut off by the solid state relay (SSR) controlled by the micro control unit (MCU) to reduce the standby power.
