advantage of super sensitive intruder alarm

Super Sensitive Intruder Alarm Circuit Principle:

IR transmitter always emits the IR (Infrared) rays which have to be received by IR receiver. When there is an obstacle in front of IR sensor, the transmitted IR rays are reflected back to the IR receiver. The output of Op-Amp is high when IR receiver receives the reflected IR rays. This output of operational amplifier is connected to the RESET pin of 555 timer.

In this paper I ve tried to aware the upcoming System programmers that in this era of Hi-Tech where concepts &things are changing every day how to be secure & also save Important confidential Data , .I ve learned about a large amount of system accessing and network attack tool practice in the past and here is what I consider the most common methods for gaining access to a target host. Most will notice that the attacks are not very high-tech. Unfortunately they don t have to be, they just need to work and if you can perform all of these attac ....etc

Intruder Detection System over Abnormal Internet Sequence

Abstract

This paper reports the design principles and evaluation results of a new experimental hybrid invasion detection system (HIDS). This hybrid system combines the advantages of low false-positive rate of signature-based invasion detection system (IDS) and the ability of anomaly detection system (ADS) to detect novel unknown attacks. By mining anomalous traffic sequences from Internet connections, we build an ADS that detects anomalies beyond the capabilities of signature-based ....etc

pir based intruder alarm using 8051 c language

Interfacing PIR sensor to 8051 microcontroller.
PIR sensors are widely used in motion detecting devices. This article is about interfacing a PIR sensor to 8051 microcontroller. A practical intruder alarm system using PIR sensor and 8051 microcontroller is also included at the end of this article. Before going in to the core of the article, let s have a look at the PIR sensor and its working.
