Security Alarm systems
Why Should I Have a Security Alarm System?
It is debated whether having an alarm system decreases the chances of a burglary. In theory, if a burglar is aware a  business has a system, he or she might move on to another target. Even if the alarm system does not keep a burglar from breaking in, the burglar has a tendency to stay a shorter amount of time. This may decrease the number of items stolen and the  extent of damage done.

X-Ray Scanners - Metal Detectors

The application of this new x-ray technology to airport and commercial screening uses high energy x-rays that are more likely to scatter than penetrate materials as compared to lower-energy x-rays used in medical applications. Although this type of x-ray is said to be harmless it can move through other materials, such as clothing.

An individual is scanned by rastering or moving a single high energy x-ray beam rapidly over their form. The signal strength of detected backscattered x-rays from a known position then allows a highly realistic image to be reconstructed. Since only Compton scattered x-rays4 are used, the registered image is mainly that of the surface of the object/person being imaged.

Monitored Systems

When your system is tripped, the typical sequence of events is as follows:

The security system senses something. The security system waits for 30 to 45 seconds before going into alarm allowing the homeowner a chance to deactivate the system to prevent false alarms. If not deactivated, the security system goes into alarm and sends a message to the monitoring company over telephone lines. The monitoring company receives the message, determines the nature of the alarm and verifies the alarm, generally by placing a phone call to the home. If they do not receive the proper password or do not receive an answer, they call the police. The police receive the monitoring company's call and respond
