Guide To Anti-Intrusion Systems: What They Are, What They Are For And How They Work

An intrusion detection system is a fundamental component of any security strategy, provided the anti-intrusion system has been correctly designed, built and managed. In this article, we see what an anti-intrusion system must detect, to whom and how to send the alarm signal and what to do when it is received.

Intrusion Alarm Systems: What They Must Detect

The anti-intrusion system’s goal is to promptly identify a possible intrusion into the protected site. The adoption of perimeter sensors represents a guarantee of timely intrusion detection.

Intrusion systems based exclusively on volumetric detectors could instead detect the intrusion when the perimeter defenses are overcome. If the perimeter of the environment to be protected is in contact with public transit routes, the probability of improper alarms could increase. So here is a contraindication to the use of perimeter detectors. This problem only arises if the external perimeter security is placed on a balcony, which could be reached via a gas pipe, even on high floors.

To Whom And How To Send The Alarm System Signal

A well-designed intrusion detection system must send the intrusion signal ( alarm ) to a recipient. It is he who can receive the password and react appropriately. There are more effective solutions than an anti-intrusion system, which activates only a siren in the event of an alarm. Unfortunately, the population is used to hearing these sounds coming from cars or other similar systems and tends to ignore the signal.

Acoustic Signal

On the other hand, an acoustic, optical signal is recommended; but a connection of another nature must also be activated, which can transmit the alarm to an appropriate recipient.

Telephone Dialer

Today almost all burglar alarm systems are equipped with a telephone selector which sends a pre-recorded message in the event of an alarm. In the case of sending a notice to a mobile phone, an SMS is used. Some selectors connect via the Internet. The alarm system can also be sent to the operations center of a private security institution, with which a specific contract is stipulated. It is also possible to send the report to a police switchboard.

Intrusion Alarm Systems: What To Do When Receiving An Alarm Signal?

The private citizen, or the owner of a commercial or productive establishment, must ensure that:

• The plant is functioning regularly;
• The remote alarm launch devices are functioning correctly;
• The message’s recipient is positioned to receive the message itself.

Methods Of Behavior

At this point, it is necessary to agree with the recipient on the methods of behavior to be followed if an alarm is received. Often the recipient of the alarm message is the owner of the settlement, which could be found in another part of the city. It is good that the settlement owner does not intervene personally and directly on the spot, to avoid being faced with criminals. Instead, it is helpful to contact the police, dial 112, report the incident and ask for intervention. If the owner arrives before the police, he will have to keep his distance, keeping the situation under observation and giving directions to the emergency response patrol. The owner must behave the same way when he has entered into a contract with a private security institution, which provides for the intervention of a patrol on alarm. Even in the case of personal security intervention, no action must be taken except in the presence and under the direct protection of armed guards.
