1. How does a false positive alarm differ from a false negative one? From a security perspective‚ which is least desirable? A false positive attack is where the system IDPS was alarmed but no attack ever occurred. The false negative is where an actual attack occurs and the IDPS isn’t alarmed at all. The least desirable would definitely be the false negative‚ if an attack does occur and the IDPS doesn’t even alarm well what’s the point in even having it if it isn’t going to alarm. 2. What is

Mumbai-400058‚ India‚ ekta vira@ymail.com Abstract Most of the smoke alarms available in the market use one or another kind of smoke sensor which increases the cost and also require complicated interfacing circuitry around it. But this smoke alarm circuit uses readily available photon-coupled interrupter module as smoke detector. The functioning of this smoke alarm is to continuously detect smoke and automatically activate the alarm in case of dense smoke. Loud sound is heard continuously indicating

Infrared security alarm Introduction: Not so long ago an alarm was a fairly rare sight‚ however now almost every house has an alarm of some kind. One common kind of security system is an infrared home security system. These are so popular because they are easy to install without having to drill holes and lay cable infrared radiation is invisible to the human eye but can be detected by electronic devices designed for such a purpose. The sensors are set at the door or some supervised

Smoke Detectors A smoke detector is a device that detects smoke and prevents fire. Smoke detectors were used in many houses in North America and it is important safety devices for homes. Smoke detectors are cheap and it gives alarm of any warning when it rise a high temperature that was produced by a fire this is because smoke detectors can detect the combustion gases from a small flame.

If the stimulus is a bomber‚ then a miss (failing to detect the plane) may increase deaths‚ so a liberal bias is likely. In contrast‚ crying wolf (a false alarm) too often may make people less likely to respond‚ grounds for a conservative bias.”(www.wikipedia.org) Of
