Home Alarm System - Costs, Systems & Equipment
A modern alarm system is now one of the most effective measures to reliably protect a house or apartment in Switzerland from burglary, vandalism and damage. However, the differences between wireless and wired systems, sensor types, installation effort and ongoing service costs are enormous. To make an informed decision, you need a clear overview of realistic prices, the most important system types, and the factors that really influence your total costs.
This guide shows you in a compact and understandable way what a professional alarm system costs – and how to find the right system for your home.
How much does an alarm system cost for a house or apartment?
The cost of an alarm system varies greatly depending on the system, number of sensors, and scope of installation. The price range extends from simple wireless systems to fully wired premium systems for large houses. The deciding factor is how many rooms you want to secure and what technology is used.
Average total costs per system (including installation)
Wireless alarm system – typical prices & when it makes sense
A solid wireless alarm system for an average single-family home costs CHF 5,000 – 7,000, including installation, contact sensors for doors/windows, and a motion detector. It is ideal for older buildings or apartments because no cables need to be laid. For more extensive systems with video cameras or additional sensors, the costs increase slightly to CHF 8,000 – 20,000.
Wired alarm system – typical prices & when it makes sense
Wired systems cost CHF 5,000 – 15,000 and are technically particularly stable and tamper-proof. They are particularly suitable for new buildings or renovations, as the cables can be cleanly integrated during construction. For larger houses with multiple cameras, many windows and extended protection, the costs quickly amount to CHF 20,000 – 40,000.
Premium/Hybrid systems – for large or complex properties
Hybrid or high-security systems are suitable for very large single-family homes, villas or commercial properties. These start at around CHF 15,000 and can cost up to CHF 50,000 or more – depending on the number of sensors, camera surveillance, access systems & smart home connection. They offer maximum reliability, flexible expandability and professional monitoring solutions.
Common additional costs
Emergency call center
The connection to a professional emergency call or alarm center costs CHF 500 – 1,000 per year. In an emergency, this checks the alarm, calls security services or alerts the police. For many owners, this is an important component, as they want full protection when on vacation or away.
Maintenance
Regular maintenance amounts to CHF 300 – 600 per year, depending on the system size. Sensors are checked, software is updated and batteries are replaced. Maintenance ensures that the system functions reliably and minimizes false alarms.
Sensor extensions
Additional window contacts, motion detectors or glass break sensors cost CHF 80 – 250 per sensor, plus installation. Depending on the number of windows and doors, this can account for a noticeable proportion of the total costs. However, extensions are often useful to avoid blind spots.
Video cameras
Indoor or outdoor cameras cost CHF 400 – 1,000 each, including installation. Modern cameras work with motion detection, night vision and app control. They not only increase security, but also provide valuable evidence in an emergency.
App / Smart Home connection
Integration into a smart home system or an app usually costs an additional CHF 200 – 250. This allows the system to be conveniently armed from anywhere, messages to be checked or camera images to be called up. With high-quality systems, the app is often already integrated, but sometimes requires a subscription.
The most important cost factors – What really influences the price?
Number of doors/windows
The more openings that need to be secured, the more contact detectors are required – this drives up material and installation costs. The effort increases noticeably, especially in large houses or properties with many patio doors.
Number of motion detectors
Motion detectors cover entire rooms and are crucial for interior monitoring. Each additional room or each additional floor increases the number of detectors required and thus the total costs.
Type of control panel
The alarm control panel is the heart of the system. High-quality control panels offer more tamper protection, higher security levels and better integration options, but cost significantly more.
Wired vs. Wireless
Wired systems are technically very reliable and tamper-proof, but require more installation effort – ideal for new buildings. Wireless systems are cheaper to retrofit, but battery changes and radio range can play a role.
Video surveillance
Cameras massively increase security, but are one of the biggest cost drivers. High-quality indoor and outdoor cameras including recording, night vision and app connection cause additional costs and sometimes require stronger networks.
Smart home integration
If the alarm system is to be networked with lights, shutters, door locks or building automation, the costs for modules and programming increase. In return, the comfort and responsiveness in an emergency increase significantly.
Security level (EN 50131 Grade 2 / 3)
Systems with Grade 2 are ideal for residential buildings, Grade 3 corresponds to a higher, commercial security level. The higher the grade, the more expensive the components – but the tamper and sabotage security also increases.
Installation effort
Stairwells, winding rooms or large properties make the wiring or placement of the devices more complex. The more complex the installation, the higher the labor costs in the final quote.

Wireless vs. Wired – Which alarm system is right for your home?
The right type of system depends heavily on the building, your security requirements and your budget. Wireless alarm systems are flexible and ideal for existing houses, while wired systems offer maximum stability and tamper protection – but with greater installation effort. Hybrid systems combine both worlds and are particularly suitable for larger or complex properties. The following sections will help you decide clearly which system best suits your home.
Wireless alarm system
Wireless alarm systems work wirelessly and are perfect for older buildings or apartments where walls should not be opened. They can be installed quickly, expanded at any time and easily connected to additional sensors or smart home elements. Modern wireless systems work in an encrypted and reliable manner – however, they are more susceptible to interference if many radio signals are present in the building. For most single-family homes, wireless offers excellent value for money.
Advantages:
● Quick and clean installation
● Easy to expand, ideal for additional sensors
● Cheaper than wired systems
Disadvantages:
● Batteries must be changed regularly
● Slightly more susceptible to interference than cable systems
● Range may be limited depending on the design
Ideal for whom:
For owners of existing houses or apartments who want a flexible, cost-efficient and expandable solution.
Wired alarm system
Wired systems are the most stable and tamper-proof option – they function independently of radio ranges or batteries. They are particularly suitable for new buildings or large houses where cables can be cleanly integrated during the construction phase. The installation is more complex, as cables have to be laid, but the system convinces with maximum reliability, low susceptibility to interference and long-term operational safety.
Advantages:
● Maximum tamper & failure safety
● No battery changes necessary
● Ideal for large or complex buildings
Disadvantages:
● Higher installation effort
● Intervention in walls/floors necessary (old building)
● More expensive than wireless systems
Ideal for whom:
For new buildings, large single-family homes or security systems with a high level of protection (e.g. valuables, company premises).
Hybrid system
Hybrid systems combine wireless and wired technology. They are ideal for buildings where cables are partially present, but additional areas are to be flexibly supplemented via radio. This allows critical zones to be secured with cables, while less relevant rooms are monitored using wireless sensors. These systems offer both stability and flexibility, but are priced in the upper segment.
Advantages:
● Highest flexibility: combination of wireless + wired
● Expandable, even for large buildings
● Very high failure safety
Disadvantages:
● Higher acquisition costs
● Planning is more complex
● Installation takes longer than with pure wireless systems
Ideal for whom:
For large or winding houses, mixed renovated buildings or owners who want to combine maximum security with maximum flexibility.
Which sensors are useful for an alarm system?
Not every sensor is necessary in every house. The deciding factor is how many entrances you have, how winding the rooms are and whether you want to cover burglary protection or additional fire/water protection. Here is a clear, honest assessment:
Door/window sensors
They are the foundation of every alarm system because they monitor doors and windows – i.e. the typical entry points for burglars. Useful for every house and every apartment. Unnecessary only on windows that are structurally impossible to reach (e.g. small skylights on the 3rd floor without a balcony).
Motion detectors
They complement door/window sensors and monitor interiors. Particularly useful in hallways, stairwells or living areas. Models with “pet immunity” are important for households with pets. Unnecessary in small, rarely used rooms or if the complete shell (windows/doors) is already secured.
Glass break sensors
Detect splintering glass and are recommended for large window fronts, patio doors or easily accessible basement windows. Particularly useful if burglars might try to smash the window without opening it. Unnecessary for old, small windows or if strong shutters are already installed.
Smoke and water detectors
These sensors have nothing to do with burglary protection – but they prevent the most expensive damage in the house. Smoke detectors are practically always useful. Water detectors are worthwhile in basements, technical rooms, near washing machines or near the heating system. Unnecessary in dry rooms without water connections.
Indoor/outdoor cameras
Cameras are a strong deterrent signal and help to understand events. Useful in the entrance area, on terraces, in carports or in stairwells. Unnecessary in bedrooms or private rooms (data protection & comfort). Important: Cameras do not replace sensors, they only complement them.
Sirens (indoor/outdoor)
Sirens deter and ensure that burglars flee immediately. An outdoor siren has a particularly preventive effect, but may be subject to approval or regulation (volume/signal time). Indoor sirens are almost always useful. Unnecessary only if you want exclusively a silent alarm (e.g. to a control center).
What are common mistakes with alarm systems?
Too few sensors
Many owners try to save money and install only a few door or window sensors. The problem: burglars almost always choose the weakest access point – and that then remains unsecured. Therefore, it is better to plan one sensor per critical access point so that there is no gap.
Incorrect placement
Motion detectors, cameras and contact sensors only function optimally if they are placed correctly. Positions that are too high, too low or unfavorably aligned generate false alarms or detect intruders too late. A specialist company analyzes the rooms and determines the ideal sensor positioning.
Cheap sets from the Internet
Cheap DIY kits sound attractive, but rarely offer tamper protection, secure encryption or stable components. Many of these systems trigger false alarms or no longer function reliably after a few months. Security should never be determined by the cheapest provider.
No maintenance
Even high-quality systems need regular checks: replace batteries, test sensor functions, update software. Without maintenance, the error rate increases – in an emergency, the system might not even trigger. An annual maintenance by the specialist company is ideal.
No on-site analysis by a specialist company
A standard set rarely fits an individual building optimally. Without analysis, important weak points such as basement doors, patio windows or secondary entrances are overlooked. A professional recognizes these risks immediately and plans a tailor-made system.
An alarm system only protects if it is planned correctly
An alarm system can make your home massively safer, but the quality depends on the planning. The correct number of sensors, professional installation, high-quality components and regular maintenance determine whether the system really protects in an emergency. Those who rely on expert advice early on save themselves bad purchases, unnecessary costs – and significantly increase the safety of their family.
