The most important facts in brief

  • Alarm systems make it possible to detect a break-in immediately and to catch the perpetrator as quickly as possible. Should there be a break-in within your own four walls, the alarm system goes to sleep immediately.
  • Basically, a distinction is made between wired alarm systems and wireless alarm systems, whereby both variants can be purchased in different detector forms. As a rule, wired systems are more expensive. The wireless variants can usually be connected to a mobile phone via an app.
  • There are different types of detectors with which you can secure the house. With a very loud signal, the perpetrators are deterred by an alarm system and thus driven away. The silent alarm calls an emergency call centre or the police directly so that the perpetrator is caught in the act.

Advisor: Questions you should consider before buying an alarm system for your home

How does a house alarm system work?

In the past, an alarm system was not common for houses, but rather something for commercial properties that seemed particularly interesting for burglars.
Today this is different. The number of burglaries has also increased in private buildings and with it the number of electronic protection systems has also increased accordingly.

Thanks to the increased demand for alarm systems, the price has dropped over the years, so if you are just about to buy an effective alarm system, you no longer need to spend a fortune on it. Such a device can easily be paid for out of the household budget.

An alarm system usually consists of three different components:

  • Sensor/ contact detector
  • Head office
  • Signal transmitter

The sensor works on the basis of movements. So it sends an alarm to the central office whenever an intruder enters your property. This triggers the desired reaction at the central office.

There are also magnetic contact detectors that send a signal to the control center if the magnetic circuit is interrupted. Many break-ins also occur due to the breakage of the glass window filler and there is also the so-called glass breakage detector.

This is an acoustic detector that reacts to the clinking shard. In the central alarm system the device is controlled and various settings, such as volume, can be made.

Here you can, for example, set up a silent alarm, which, if triggered, will directly alert the police and yourself through your own smartphone.

The signal generator carries out the desired alarm process by means of a visual or acoustic signal. Depending on various factors, such as the type of house, the system and the individual needs of the user, the signals can vary.

It can be a howling and flashing outdoor siren, which is attached to the outside wall of the building and is intended to alert the neighbourhood, or a silent alarm, which contacts a connected emergency call centre via an integrated SIM card even if the Internet line is disrupted.

But what can you do if an over-motivated burglar manages to get into the house despite securing the “outer skin” of the building? For this purpose, there are so-called motion detectors that can be placed in places that the intruder must pass through in any case in order to move through the house.

If you want to increase your security even more, you can supplement your alarm system with a fire and smoke protection supplement. There are also special hazard alarms that extend the alarm system, so that your home is protected against fire and smoke.

How does the installation of an alarm system for the house work?

When buying and installing the alarm system, you should pay special attention to the fact that it can be integrated into your daily routine.
It should be as easy as possible to activate the system and quickly deactivate it when you get home. Children should also be able to operate the system easily.
The difficulty of the installation varies according to the type of system you have. A wireless alarm system is relatively easy to install. In most cases, these products are also sold directly with installation instructions. However, it is advisable to turn to a professional.
In principle, it is a matter of what type of detector or sensor you have chosen. Magnetic contact detectors can be mounted directly in the windows and doors. The situation is different with motion sensors, as you have to choose certain locations.

If you would like to have a system for example as an all-round protection for your home, the device can be easily installed in the house by yourself.

For the installation of the central system, detectors, signaling devices and equipment connected by cables, it is also possible to hire a security company.

For the installation of a wired alarm system, we recommend that you hire a security company that guarantees a safe and professional installation.

As a general rule, a professional alarm system should always be installed by a specialist. The professional is familiar with the components and other features, so that installation and set-up can be carried out without any difficulties.

He works with the equipment on a daily basis and is familiar with the technology of well-known manufacturers.

A specialist can also identify any gaps in the security of the house and assess the potential dangers. If there are security weaknesses in the building, he can make suggestions for solving the problem.

Where can I buy a house alarm system?

You can buy alarm systems both in electrical stores and directly from the manufacturer. In addition, there are alarm systems nowadays in many online shops to buy. So you can order the alarm system from home in a relaxed manner.
There are also countless specialist companies that deal with the sale and installation of alarm systems. With a specialist you will not only get the professional advice, maybe the installation in combination with the hardware is also worthwhile.
According to our research, most home alarm systems are sold through these online shops:

Media Markt

All alarm systems for a house, which we present to you on our site, are provided with a link to at least one of these shops. If you have found a device that you like, you can strike immediately.

What does a house alarm system cost?

There is a wide price range between the different alarm systems. Depending on the equipment, manufacturer, cable variant and other factors, the cost varies. The range can be from about 10 to 500 euros.
Whether you want to have a wired system or are looking for a wireless alarm is accordingly decisive.

The very simple wireless alarm systems can be purchased for as little as 10 euros. If you put more emphasis on equipment, quality and functions, the price point increases up to 500 Euro.

You can’t buy the wired versions from such a low price – the price range of these systems is between 180 and 400 Euros.

A professional alarm system from a security company is of course about more expensive. The price ranges between 1600 and 6400 Euro for small or bigger houses.

You should also take into account the cost of installation, as a professional alarm system should always be installed by a professional.

Apartments and small houses are usually secured within one day, for a larger house there may be two days of work. You will spend about 400 to 900 Euro for the working time.

What alternatives are there to alarm systems for a house?

There are also other ways to protect yourself from burglars, for example with a bar lock. You should first think about how your house is self-protected before you buy an alarm system.
Here we give you a few tips on how to make your house secure:

An extra burglary protection ice especially important in the holiday season. Especially during the holiday season many apparently empty apartments and houses are a popular target for burglars.

We give you these tips which you should follow when you are on holiday:

  • Have neighbours empty your letterbox
  • Have light controlled by a timer
  • Lock all windows and doors
  • Do not hide spare keys outside
  • Do not leave any climbing aids, such as ladders or garden chairs

Here it is also important to note that for more than ten years the percentage of attempted break-ins (i.e. unsuccessful break-ins) has been rising steadily.

This development shows improved safety technology. It pays to secure your house well, because the more houses and apartments are effectively secured, the harder it is for thieves.

Decision: What types of home alarm systems are there and which one is right for you?

Once you have decided on a professional solution, the question remains: Do you prefer a wired or a wireless system?

If you consider the installation costs, it quickly becomes clear that a radio-based system is often cheaper because you save yourself the costly laying of cables.

Furthermore, a radio system is much easier to install than the wired version, so that self-installation is also possible.

Both systems have their advantages and disadvantages. In principle, however, both variants offer the same range of functions.

What distinguishes a wireless alarm system for a house and what are the advantages and disadvantages?

A wireless alarm system is installed in the house completely wireless. The power supply for the sensor is provided by an inserted battery and the control panel is usually installed directly in the socket.

Radio alarm systems are usually cheaper to install, can easily cover a long range and retrofitting is possible without much effort.


Remotely controllable
Easy to install
Self-assembly possible


Power supply by accumulator or battery
Easier to manipulate

The new additional device is simply registered in the control centre by radio. Besides, there is a great variety of wireless alarm systems available today.

You can control many of these radios from your smartphone or tablet. Control and ease of use often allows you to create your own app suitable for iOS and Android operating systems. If you are not at home, the alarm system is very easy to control even from a distance.

In case of an alarm, you or an emergency call centre will be notified directly.

What distinguishes a wired alarm system for a house and what are the advantages and disadvantages?

In the case of a wired alarm system, each component must be connected to the control panel by cable. This can usually only be installed by a specialist. The energy supply of the system is provided by a fixed power line.

In general, the sensible area of application for a wired alarm system is where no radio system can be used. This can occur, for example, when strong electromagnetic fields or thick reinforced concrete walls prevent radio transmission.


One-time effort for the installation
Power supply by domestic electricity
Connection of several alarm systems


Complex installation
Difficult to retrofit
Can be more costly

On the other hand, the important advantage of this variant is that this product requires no repeated maintenance. So if you want to install an alarm system in your house and don’t want to worry about anything else, the wired alarm system may be interesting for you.

Purchase criteria: Based on these factors you can compare and evaluate house alarm systems

In the following we would like to show you the factors you can use to compare and evaluate alarm systems for your home. This will make it easier for you to decide whether a particular home alarm system is suitable for you or not.

In summary, these are:

  • Nature of the house
  • Type of detector and area of application
  • Type of notification
  • Equipment
  • Emergency power supply

Nature of the house

Depending on the size and type of house, various factors change when purchasing and using the alarm system. For example, for an apartment in an apartment building, you only need an indoor alarm system.

If the whole society of the apartment house decides to use a common alarm system, the house can also be secured from the outside by windows and doors.

Basically, it is also possible to install various additional functions, such as smoke and gas detectors or a surveillance camera for the yard.

The advantage of this is that the one-off costs of the installation and the device are distributed among the occupants, which makes them cheaper than in a detached house.

The costs of an alarm system are higher, especially for a single-family house. On the other hand, fewer indoor units are needed for the different signal transmitters (for example, the system keyboard to turn on and off). In addition, the selection and installation is easier if you decide independently and alone.

Type of detector and area of application

Basically, you can buy alarm systems for either outdoor or indoor use. Depending on the type and functions of the system, the area of application is different.

  • Opening detector: Opening detectors are basically sensors that you mount on doors and windows. Usually they work with a magnet and a contact detector. The opening detector is mounted directly on the frame of the window or door. The distance between the two parts must not exceed 2 cm. If there is a break in the contact between the magnet and the contact detector, the alarm is triggered.
  • Outer skin protection: The so-called outer skin protection, which works with a radio signal, works on the basis of all opening contacts and glass breakage sensors. All windows and doors are secured within the perimeter security system. If an attempt is made to break in from outside, the alarm is triggered immediately. When securing the outside of the house, you should consider all possible gaps, including for example the roof windows, so that the house is completely protected.
  • Motion detectors: A motion detector is a very often used variant. These systems work either with electromagnetic oscillations or by sensing changes via ultrasound or infrared. Safety is particularly high with infrared motion detectors, because this technology does not overlook anything and is based on the detection of heat sources. The motion detectors should always be installed by a professional.
  • Security camera: In addition to the motion detectors, you can also have security cameras installed. The camera is useful mainly as evidence, so that the burglar is caught after his crime. However, there are certain guidelines that must be followed when installing the security camera. The visual recordings may only be made on your own property so that the camera is not directed at the neighbouring property.
  • Glass breakage detector: Intelligent and modern glass breakage detectors are designed to detect glass breakage. That is why these devices are installed in the immediate vicinity of windows or glass terrace windows. If a window pane is to be broken, the detector detects this noise and sends a signal to the central unit. However, it is important to note that such an acoustic detector can cause a false alarm if a drinking glass or bottle is broken.

Type of notification

Basically there are three different ways to get notification from the alarm system:

  • Siren
  • Stilstaand alarm
  • Electronic notification

The howling and flashing outdoor siren is the classic. It is attached to the outside wall of the building and is intended to alert the neighbourhood. But often this is not an effective type of alarm. Sometimes the neighbours do not react quickly enough or are not at home, for example.

It can be the wailing and flashing outside siren, which is attached to the outside wall of the building and is intended to alert the neighbourhood, or a silent alarm, which contacts a connected emergency call centre via an integrated SIM card, even if the alarm is not activated.

With a silent alert, you receive a call or a notification is sent to a specified phone number and/or email address.

What has become quite common nowadays is a notification on the mobile phone. Depending on the model, you can receive notifications about calls, SMS, voice messages, push notifications or out of office hours.

Many alarm systems even have their own app that can be used directly with a mobile phone or tablet […]


In most cases the wireless alarm systems can be conveniently controlled via smartphone and other devices. For the intruder it becomes more and more difficult, since hacker knowledge is almost required to overcome the hurdles of the

The smart systems have the advantage that the security in the house is also there when you are on the road or at work. Many models come with a corresponding smartphone app.

You can obtain these by scanning the corresponding barcode or via the homepage of the manufacturer. Most of the time this app is completely free and can be protected by a code.

It is very practical that smoke and gas detectors can also be integrated into professional alarm systems. These detectors are basically sensors for smoke and gas and trigger the signal if smoke gas escapes or if a fire goes unnoticed.

Surveillance cameras can also be sensibly integrated into an alarm system. For this purpose a combination with other detectors from the system is possible. The camera can be very helpful after the break for potential evidence for the police.

Emergency power supply

In the case of wired alarm systems, the central units operate via the power connection, whereas the detectors must be powered by batteries or accumulators. But what happens if there is a power failure?

The wired alarm systems are plugged into the socket all year round and therefore only need an additional emergency battery.

This battery ensures that the alarm system continues to function during the power failure and does not weaken.

Depending on which model of system you have, the emergency battery has capacity for up to 72 hours.

Most wireless alarm systems have an internal power supply in the form of batteries or accumulators. Usually these can last for about one year.

However, you should take note of the duration of the device before you buy it. If the device would only run for a short time without changing the battery, there is too high a risk of break-in if the battery or accumulator is empty.

Some manufacturers offer the function of informing you as soon as the device has too little battery. This allows you to carry out maintenance without having to worry about your house being unsecured.

Trivia: Worth knowing facts about the home alarm system

Can I install an alarm system in the house with dog or cat?

Security is important to all of us. We secure our houses with alarm systems and with motion detectors outside and inside the house. But now you have a dog or a cat that moves freely in the house. There is also a solution here.

Many manufacturers offer the Animal Immune Detectors, which can be installed so that pets can be unnoticed.

My house alarm goes off for no reason.

It can also happen that your alarm system goes off for no apparent reason. Some models can cause a false alarm.

For example, a glass breakage detector might be too sensitive to other acoustic triggers (e.g. if a drinking glass or bottle is broken) and without there being a break-in pass the signal to alarm.

It can also happen with motion detectors. Often, if you leave a window open or do not turn off an air conditioner, light objects such as paper can fall to the floor because of the draught and trigger the alarm system.

Such similar stories happen with different models of alarm systems and most often it is a false alarm. However, if you feel that your system goes off without triggering, you should turn to a professional or directly to the manufacturer.

Can I connect my home alarm system to the police?

With the different models, you can decide whether the burglar alarm is directed to the responsible security company, yourself or to the police.

This is particularly practical for a silent alarm. Here the burglar does not notice that he has been discovered, but the security service or the police are already on their way to catch him.

With an alarm system connected to the nearest police station, the thieves quickly end up behind bars.

In many cities in Germany, the police even offer targeted advice and provide information on modern security technology or recommend top-class test winners for alarm systems.
