At Dumo Seguridad we install customised alarms in Barcelona adapted to each space and need. Our security alarm system includes intruder, fire, water leak and gas leak detection, with immediate mobile phone notification and connection to the Alarm Reception Centre (ARC) for a coordinated response 24 hours a day.
If you have a second home on the coast or in the mountains, you know how difficult it is to have peace of mind when you don't visit for weeks at a time. And if you run a business with stock or machinery, a theft can mean significant losses and days of downtime.
At our alarm company in Barcelona, we have been helping to reduce these risks for more than 19 years. All our security alarm systems include:
If you are worried about what might happen in your home while you are at work, if you don't sleep well when you travel or if every time you arrive at your business you check that everything is in order, you have probably already considered installing an alarm.
Having an alarm system in Barcelona completely transforms the situation.
Deterrent number plates: the difference DUMO SECURITY
At DUMO SEGURIDAD we offer much more than just a plaque. Unlike conventional alarm companies, our badges generate a superior deterrent effect. Why? Because behind a DUMO SECURITY plate the intruder does not know what he will find: the type of system, the degree of protection or the frequencies used. This uncertainty is the key to prevention.
In contrast, with a badge from a traditional company, the intruder knows exactly what he is up against, reducing its deterrent effect. With DUMO SECURITY, doubt is your best defence.
Hiring an alarm in Barcelona not only protects you when someone tries to break in. The simple presence of the system reduces the likelihood of them trying. And if they still do, the immediate detection and notification of the security forces drastically shortens the time the intruder can remain inside, minimising damage.
The main objective of our alarm company in Barcelona is to protect people and their property. Installing an alarm system in Barcelona allows you to know that everything is under surveillance even when you are not there. This is the benefit and daily advantage that our clients value the most.
With alarm systems in Barcelona you can monitor your space from anywhere. The app allows you to see in real time whether the alarm is armed or disarmed, activate or deactivate it remotely, consult the history of recent events and receive instant alerts if something is detected.
This remote control is particularly useful for second homes, businesses and apartment buildings.
Our security alarms not only protect against burglary. They can also be integrated with smoke and heat detectors, gas leakage sensors and flood detectors.
This makes the alarm a comprehensive security solution, not just an intruder detection system. In addition, thanks to our technical maintenance, we regularly check that all detectors are working properly.
Having alarms in Barcelona means being connected to an Alarm Reception Centre, which confirms whether an event is real and activates the intervention protocol. This may include notifying the police or emergency services, depending on the type of incident and the conditions of the contracted service.
Our security alarm systems include video and photo verification, so that the ARC can quickly confirm whether the alarm is real, speeding up management and improving response times.
Our professional alarm systems are much more than just sensors and a siren. It is a set of devices that work in a coordinated way to protect your space, detect anomalies and warn you in time.
At Dumo Security we do not work with closed packs. Each alarm installation in Barcelona is custom designed and installed after analysing your space, your accesses and your specific needs.

The control panel is the brain of the security system. It receives the signals from all sensors, validates if it is a real event, activates the sirens and sends the corresponding warnings.
Our panels incorporate tamper protection (tamper) that detects if someone tries to tamper with the equipment, and use encrypted communications to avoid interference. In our professional systems, the control panel has battery backup and dual communication channels (GSM + internet) to remain operational even if the power or internet is cut.

PIR (passive infrared) motion detectors are responsible for monitoring the interior of the space. They detect temperature changes caused by the movement of people and send the signal to the control centre.
Our alarm companies work with high-precision sensors that reduce false alarms caused by draughts, temperature changes or reflections. And if you have pets at home, we install pet immune detectors that ignore the movement of animals, avoiding unnecessary jumps.

These magnetic sensors are installed at main entrances and detect if someone opens or knocks on a door or window when the system is armed. Their great advantage is that they warn you before the intruder enters, giving you time to react.
In Barcelona we usually install them at the front door, balconies, windows overlooking courtyards, rear entrances to premises and any vulnerable point detected in the security study.

These devices extend the protection of your alarm system in Barcelona beyond burglary. Smoke and heat detectors warn of a possible fire. Gas sensors detect butane, propane or natural gas leaks. And flood detectors alert you if there is a water leak that could cause damage.
With these elements, your system becomes a complete protection and alarm solution for any emergency in the building.

The siren serves two functions, deterring the intruder and alerting the surroundings. When the alarm is triggered, the loud sound makes the offender want to leave as soon as possible, reducing exposure time and potential damage.
Outdoor sirens, in addition to sound, usually incorporate light signals to facilitate the location of the property in the event of an intervention. They are a basic element in any alarm installation in Barcelona.

For a security alarm service to work properly, it needs to be able to send alerts even in the worst circumstances. Our alarms use multiple communication channels: internet connection (WiFi or Ethernet) as the main channel and GSM/GPRS 4G module as a backup.
This means that if someone cuts the internet cable or there is a power cut, the alarm continues to send alerts over the mobile network. And with battery backup, the system remains operational for hours without power.
This mechanism is especially important in businesses with perishable goods (refrigerators, cold stores) where a prolonged power cut can spoil the goods, and in second homes where power cuts are more frequent.
The process of contracting an alarm with us is quick, simple and transparent. We accompany you from the first contact until your system is fully operational.
You can call us at, send us a WhatsApp or fill in the form on the website. You can also write to us at info@dumoseguridad.com. In this first phase we collect basic information such as: type of space (home, premises, community), number of accesses, hours of use, main concerns and any details that will help us to prepare the technical visit.
Once the visit has been arranged, a specialised technician will come to your location to carry out a complete security study. We analyse all entrances and exits, identify vulnerable points, assess the ideal location for sensors, control unit and sirens, and explain the options available.
During this visit we define what type of security alarm systems you need, how many devices are required and what type of contract is best suited to you.
Free and non-binding studyOnce the proposal has been approved, our alarm installers carry out the installation. We place sensors, control panel and sirens in the defined locations, configure communications and test the operation of each device.
Alarm installation in Barcelona adapts to your schedule to minimise inconvenience. In most cases we complete the work in one day, without building work or complications.
Installation in less than 24hWhen we finish verifying the operation, we leave the system fully operational. We configure the app on your devices, create the necessary users and codes, explain how to arm and disarm the system, and do an alarm jump test so you can see how the warnings work.
Once the installation has been carried out, checked and the functionalities have been explained, you can count on our alarm service with 24-hour attention seven days a week. You can contact us by phone o WhatsApp to resolve incidents, consult doubts of use, request extensions to the system or schedule maintenance checks.
Being available when you need us is a fundamental part of our work as an alarm company in Barcelona.

All our equipment is approved and connected to the ARC, complying with the requirements demanded by the regulations for authorised alarm system companies.
Our commitment does not end with the installation. We offer a 24/7 security alarm service to manage incidents, resolve technical queries and coordinate maintenance work when necessary.
If your system has a problem at 3am, there is someone on the other end of the phone to help you thanks to our on-call service.
Every security alarm installation starts with a detailed analysis of the space: access, usage routines, assets to be protected and specific risks. Based on this diagnosis, we design a customised proposal with the number and type of devices that you really need.
This approach sets us apart from alarm and security companies that offer standard solutions without taking into account the particularities of each property.
The installation of alarms in Barcelona is carried out by our own technicians, not by subcontracted teams. This translates into a more careful execution, close and personalised attention, better location of the devices, correct configuration of the control panel and exhaustive tests before the system is considered operational.
As an alarm installation company in Barcelona, we take responsibility for every job we do. If something doesn't work properly, we come back and fix it.
If you are looking for alarm companies in Barcelona to protect your home, business or community, at Dumo Security we offer you personalised advice, a free security study and a customised proposal.
We work with different contracting modalities so that you can choose the one that best suits your needs and budget.











Yes, our alarms in Barcelona have a monthly cost that varies depending on the payment method chosen and the services you wish to contract. We will provide you with a personalised quote adapted to your needs.
Home alarm installation with 3-5 sensors, control panel and siren is completed in 3-5 hours. Businesses or communities with more devices or wiring needs may require a full day or two days to complete the installation.
When the alarm is raised, the first thing we check is whether the event is real. If there is video verification, we review the images. If not, we try to contact the owner to confirm. False alarms are often caused by misadjusted sensors, pets or user error. After identifying the cause, we adjust the sensitivity or explain how to avoid them in the future.
Yes, our security alarm systems have a built-in battery back-up that keeps the system operational for several hours without power. In addition, they use two-way communication (internet + GSM/GPRS 4G), so that even if the power and internet fail, the alarm continues to send alerts via the mobile network.
Yes, all our alarms in Barcelona include an app to arm and disarm it, check the status in real time, review the history of events, view images in real time through cameras and photo detectors (if the system allows it) and receive instant notifications when something is detected. You can manage your alarm in Barcelona from anywhere with an internet connection.
Yes, we install alarms in communal areas of communities, such as gates, storage rooms, car parks and accesses to private areas. The system can be integrated with access control and video surveillance cameras for complete protection. The approval of the owners' meeting is required before proceeding.
Yes, our systems allow partial arming (night mode or stay mode) that activates only the perimeter sensors while you move freely inside. If you have pets, we install pet immune detectors that ignore the movement of animals up to a certain weight, avoiding false alarms.
Yes, we install professional grade 2 and grade 3 approved alarm systems. Grade 3 is indicated for high-risk installations (jewellery shops, lottery administrations, tobacconists with large volumes, etc.) and is mandatory when required by regulations or insurance companies. During the security study we assess which grade you need according to your activity and risk level.
Yes, for estates, villas with gardens and open spaces we install perimeter alarms with outdoor photo detectors, infrared barriers and long-range volumetric sensors. These systems detect intrusion before the intruder reaches the house. They can be complemented with video surveillance to verify events remotely.
Depending on the type of contract agreed with our alarm company in Barcelona, if a time commitment is established and is not met, there may be a penalty for early termination. However, we are quite consistent and try to reach an agreement that is fruitful for both parties.
