Alarm systems


Effective and reliable systems

Italpol Vigilanza includes among its ranks a department dedicated to the design and installation of alarm and video surveillance systems tailored to the needs of the individual customer. It is possible, by taking out a monthly subscription, to connect your alarm system (old or new) to our Italpol Vigilanza Operations Room with 24-hour monitoring, where you can also request the prompt intervention of a patrol in the event of an alarm.


What an alarm system provides

Alarm centre

The purpose of the alarm control panel is to manage, activate and deactivate the entire system. At the precise moment when the alarm is triggered, it determines which actions to take, which actuators to activate and their duration.

Each alarm centre allows the system to be divided into different areas with the possibility of managing them independently of each other. One or more sensors can be associated with each zone.

This division is important for 2 reasons:

1) The possibility of activating the alarm system only in certain areas of the house.

2) The possibility of accurately detecting intrusions and distinguishing them from false alarms.


Actuators have the task of activating the alarm and alerting those concerned of an intrusion by strangers and malicious intruders.
The term actuators refers to two specific devices:

Alarm sirens

Alarm sirens are equipped with a flashing light, double-covered and self-powered so that they can continue to function thanks to an internal auxiliary battery in the event of electrical tampering.

In addition to this, it is always advisable to install an internal siren.

Telephone dialers

The telephone dialers have the task of alerting those concerned and the Control Room. When the sensors detect an intrusion, a telephone call is sent to one or more numbers established during the system configuration phase.

A particular category of dialers are those known as GSM, which do not exploit the traditional telephone line but use a prepaid GSM card.


What they do
  • Perimeter sensors: protect the perimeter of your home by securing the areas in front of the house entrance.
  • Curtain sensors: are used in front of entrance doors, they create a triangular barrier that detects the presence of an intruder.
  • Window-door sensors: are installed on window frames and doors, they detect attempted break-ins from entrances.
Active infrared sensors

Two thin columns communicate with each other via infrared. These create an invisible barrier that triggers an alarm once it is interrupted.

Passive infrared sensors

Dispositivi in grado di riconoscere le variazioni di temperatura ambientale all’interno dell’area protetta. In questo modo, rilevano il passaggio di una persona nell’area protetta.

Microwave sensors

Devices capable of creating a sensitive barrier through the emission of high-frequency electromagnetic waves. Ideal for large spaces.

Dual technology sensors

These sensors combine microwave and infrared technology.


Three types of systems are generally used to activate or deactivate the burglar alarm:

Internal or external keyboard

Located inside the home, it represents the most secure system as alarm activation is managed via an alphanumeric code. An additional external keypad can be installed in addition to the internal one.

Electronic keys

They contain a special code selected from billions of possible combinations. If they are lost, they are immediately reprogrammed.


Remote controls work by radio frequency and allow, like electronic keys, the alarm system to be activated from the outside.


What are the advantages and disadvantages of a traditional burglar alarm and a wired one?

Many people think that traditional wired systems are much safer than wireless ones. On the one hand, this is true because wired transmission is more reliable and guarantees constant performance over time, regardless of weather conditions and the presence of various interferences.

The advantages of a wired alarm:

  • Greater reliability than a wireless system, as cable transmissions are not subject to interference of any kind;
  • It is the best and most economical solution if you already have an ad hoc set-up (you can save up to 20% for the same number of components) since the individual components are inexpensive;
  • It covers long distances, is not subject to the constraints of the type of masonry, and is therefore ideal for large houses and/or sheds;
  • There are no battery maintenance problems on the sensors.

The disadvantages of a cable alarm:

  • Careful prior planning is always required, if you get a location wrong you have to redo the installation locally (move the cables to the new location);
  • If you do not already have adequate provision, you have to intervene with the execution of tracks and masonry work, incurring considerable expense and time, and the inconvenience of such work must be taken into account;
  • Modifications and implementations are always possible, but they too require work on the wire network.

Where, then, is it advisable to install a classic burglar alarm?

In newly built houses, or at least in fairly recent ones, there is almost always already provision for the installation of an alarm system. In such cases, it is advisable to call in a technician who, equipped with the necessary components, will install a classic wired burglar alarm. All he has to do is position the control unit and the sensors and run the cables: without making a mess or doing any damage. In a day’s work (two at the most if the house is very large) you will have activated your alarm system.

Even if you decide to renovate your house rather radically, by redoing the installations, it may be worthwhile to consider, as part of the work, to include the provision for a wired burglar alarm.

In houses with shielded walls, this is strongly discouraged as the radio network would have serious attenuation problems.

What are the advantages and disadvantages of a wireless burglar alarm?

Everything is now ‘wireless’. On paper, therefore, opting for a wireless burglar alarm might seem the most modern and up-to-date solution. In reality, it is not necessarily the safest. The various elements that make up the system, in fact, communicate with each other using radio frequencies and this makes it more susceptible to possible interference from other devices.

The main advantages of a wireless alarm:

  • It can be installed anywhere, even in the absence of any kind of predisposition and in inaccessible places;
  • Its installation does not involve expensive work or the laying of cables with the creation of tracks;
  • It is very flexible and versatile: at any time, it can be easily extended, modified, or integrated;
  • In the event of a move, your alarm will follow you and can be uninstalled and re-installed, adapting it to the needs of the new home.

The disadvantages of a wireless radio alarm:

  • The individual components and sensors cost a little more than those used for wired systems (the whole thing can cost up to 20% more);
  • A wireless alarm system is more vulnerable and less reliable than a wired one, because it is more prone to interference on the network;
  • One must periodically remember to replace the batteries of the various components;

Where, then, is it best to install a wireless burglar alarm?

If you need to protect a house and have no intention of breaking walls to make the necessary tracks for the cables to pass through, opting for a wireless system is the best and most popular and economical solution. A wireless alarm system, in fact, has the undoubted advantage that it does not require any masonry work and can therefore be installed anywhere you want to work quickly, cleanly and without causing damage.

Among the various disadvantages we mentioned interference and tampering with the network: isn’t it better to break through the walls and put everything underground for greater security?

It depends, as manufacturers aiming for quality and security have developed solutions that tend to reduce the possibility of sabotage (anti-jamming), such as the possibility of using one or more channels in the communication between sensors and control unit. So if you choose for a radio burglar alarm, it is a good idea to ask your trusted installer which protection techniques the control unit he proposes adopts.

What are the advantages and disadvantages of a hybrid (wired+wireless) burglar alarm?

If you are faced with complex situations, with indoor and outdoor spaces and considerable extensions to be covered, it is always better to rely on a wired system or one of the so-called mixed solutions, partly wired and partly wireless. Here, then, if it is possible to exploit a wired setup, this can then be effectively implemented with wireless components, combining at least in part the advantages of both systems.

In these cases, generally, the main control and management centre of the system is connected via cable, while many of the components (cameras, contacts, and detection sensors) are connected via wireless.

A hybrid control unit can be installed in a system designed and conceived as wired, in order to be able to use the wireless part for future extensions, obviously implying a small increase in initial expenditure.

How can the alarm system be managed when there are pets, or family members who return home at very different times in the evening?

These are questions that are asked quite often. In reality, pets, especially small ones, are not a problem. Indoor volumetric sensors can distinguish animals from humans. Clearly, large animals are incompatible with the installation of volumetric sensors, in which case we must necessarily entrust the protection of our house to a type of perimeter burglar alarm, or to a control on the doors and windows: windows, doors, roller shutters, balconies.

On the other hand, today more and more people are trying to privilege protection with perimeter alarms because they allow us freedom of movement inside the house while controlling the windows and doors, allowing us not to be taken unawares should someone try to violate our home.

How to manage the system

Unlike a few decades ago, there is the possibility of partitioning the systems and thus creating protection zones and sub-zones that are activated and deactivated independently through electronic proximity keys, keypads or touch screens, high-security remote controls, but also through Apps via smartphones.

Customisation is always possible, adapting the system to one’s own needs, one’s own habits, just as a tailor makes a made-to-measure suit, so the system must be made to the individual specifications of each customer. This will be all the more possible the more the equipment will be able to accept different solutions.

Is an inspection really necessary? Couldn't you just get a quote for an anti-theft or video surveillance system over the phone or by email?

Many people send us direct enquiries, even listing absolutely exactly what they need. In any case, it must be said that a visit from one of our technicians/salesmen offers the possibility of carrying out various checks and choosing the most suitable equipment. The habit and experience of dealing with the most diverse issues can help in many cases to save money and not to overdo it.

In the case of video surveillance, there are many aspects to be taken care of and studied: the position of a camera and its choice must take into account many aspects such as light, sunshine, night lighting, the prevailing colours of the field to be framed, the subjects or objects we want to film and recognise.

The camera is an extension of our sight; installing a camera must necessarily lead to displaying a perfect, clear image with all the necessary details.

All these things must necessarily be verified by a technician who can give the right weight, also from an economic point of view.

Does the alarm system need maintenance?

Maintenance is a key aspect in order to be certain that in the unfortunate moment of need a system will pay us back by providing an alarm to the people in charge. Just as we regularly replace the engine oil or brake pads in a car, the burglar alarm to which we entrust the security of our home and loved ones must also be serviced on a regular basis.

We offer cost-effective annual service and maintenance contracts, and periodically offer our customers inspection campaigns. We believe strongly in maintenance and after-sales service, and we do this with the utmost seriousness.

Can the alarm system be connected with law enforcement agencies? What is the advantage of having a patrol and emergency service with a private security company?

Potentially any anti-theft security system can be connected with the police. In fact, law enforcement agencies intervene according to priority and proximity.

For accidents and crimes there is a maximum priority, while for theft alarms the priority goes down. It is therefore not possible to complain if the police do not arrive on time, remembering that police patrols are limited and that the activities they have to monitor are considerable, especially in large cities. Then think about whether the system generates numerous false alarms: in this case, the police would intervene without a real reason, taking resources away from some other perhaps more urgent event with the possibility of being sued for false alarm.

Remember: the connection of your alarm system with the Carabinieri or Police is different from the connection with a Private Security Company, where in this case you can contract and establish the intervention at the home with the highest priority. There are several private security companies that, like us, subject to a monthly subscription, collect any alarms and intervene on the spot to verify the incident at affordable prices.
