The Basics about Alarm Security

A variety of items are used to catch thieves, which include PIR’s, Door Switches, Sirens, Police Autodiallers, Bells etc. You will need at least 2 – 3 people when doing a job where there is an alarm system.

Passive Infra Red are designed to comb an area of the property from intruders.. they send out beams that comb the area. anybody walking across the beams when the alarm is set will trigger the alarm off

Door switches are put on doors for security purposes incase they try and break in through the door. Some Door Switches are on a timer For Entry/Exit.

Sirens are designed to be as noisy as possible usually 114 Db the other aim of the siren is to draw attention to the fact that something is wrong.

Police Autodialler calls the police about 4 to 10 secs before the alarm goes off, it sends a pre-recorded message to the local police station.

In this guidebook, you will get information on all these devises and exactly how they are wired up and how to bypass the system so that you don’t get caught.

Perimeter Security Sensor Technologies Handbook

tazeen — Mon, 02 Nov 2009 11:58:03 +0000

Perimeter Security Sensor Technologies Handbook is intended to be used as a sensor selection reference during the design and planning of perimeter security systems

The Handbook is organized into four sections.

Section One includes this Overview of a dozen factors to be considered prior to selecting a suite of perimeter detection sensors.

Section Two consists of a description of each of the twenty-eight (28) Detection Sensor technologies discussed in the Handbook, including Operating Principles, Sensor Types/Configurations, Applications and Considerations, and Typical Defeat Measures.

Section Three (presented in the CD version only) contains a representative compendium of Vendor Information Sheets for the sensor technologies discussed in Section Two.

Section Four contains a listing of vendors who responded to the CBD notice and a cross-reference matrix of sensors and manufacturers.

The Handbook is best used (after a general review), by referring to the Applications Indices and graphics presented in Section One to determine which technologies best suit the User’s needs, and then reviewing the material in Section Two and Three which relates to that technology.

Role of a perimeter security system is fourfold: deter, detect, document and deny/delay any intrusion of the protected area or facility. The integration of sensors and systems is a major design consideration and is best accomplished as part of an overall system/installation/facility security screen.

Interior detection sensors are used to detect penetration into a structure, movement within a structure or to provide knowledge of intruder contact with a critical or sensitive item.

Exterior detection sensors are used to detect unauthorized entry into clear areas or isolation zones that constitute the perimeter of a protected area, a building or a fixed site facility. The sensors can be placed in clear zones, e.g. open fields, around buildings or along fence lines.

Reference of current perimeter security sensor technologies, capabilities, limitations, and integration methods have been mentioned in this handbook.

How to Bypass a Burglar Alarm

tazeen — Mon, 02 Nov 2009 11:44:52 +0000

This guide will discuss the circuits that guard a building’s perimeter. Therefore, they are used primarily on doors, windows and cars The most common member of this family is the magnetic switch, the little set of white rectangular boxes seen above doors of most businesses

The second line defense is the area sensor. Area sensors monitor a specific area rather than a specific point of entry. These are often called motion detectors, since anyone moving about a guarded room will be detected. The way in which these sensors achieve this goal varies between components.

Window foiling is probly the alarm which everyone is familiar with. It graces the windows of nearly every store in America, and rightfully so, it is very difficuly to bypass successfully BUT NOT IMPOSSIBLE! The ultrasonic system consists of a transmitter, which emits a frequency that lies above the human threshold of hearing, and a receiver, that monitors the incomming frequency. The entire system is generally self- contained in one unit, although occasionally on transmitter is used with several receivers.

The photoelectric alarm,or “electric eye” is a fairly common alarm today it lets off a buzz when you walk into a store.

Passive Infra-Red alarms, or PIRs are so called because they do not emit Infra-Red energy, but merely detect a change in it. A PIR probes its monitoring area, and if any changes are detected in Infra-Red (heat), it sounds an alarm.

The microwave alarm system is another transmitter/reciever motion detector, and is unquestionably the most difficult to successfully bypass.

You gain information on all that there is to know about various types of burglar alarms and ways to get around with them in this guide book.

Followings systems of alarms are described in this guide:
