At Dumo Security we install security systems with intelligent alarms with 24/7 connection to an Alarm Reception Centre, video surveillance with 24/7 recording and remote access, access control and fire protection, to protect your home or business.

Our goal as a security company is that you enjoy a security system capable of responding to any emergency situation, whether for intrusions or additional risks, including fires. Unlike other security system companies, we analyse your case and advise you in order to provide you with an effective and personalised solution.

We have been protecting homes, businesses and neighbourhood communities in Barcelona and the metropolitan area for more than 19 years. We know what type of burglaries are most common, which accesses are most vulnerable and which solutions work best in each area.
This experience allows us to design truly effective security systems, adapted to the environment and the needs of each client. Being close by helps us to act quickly, resolve incidents and offer an agile and personalised service.

We install state-of-the-art approved equipment with accurate detection, video verification, cloud recording and full control from your mobile phone.
Each security system installation we carry out incorporates the latest security innovations, such as AI cameras for perimeter protection, intelligent sensors, central units with double communication channels, etc... all of this linked to professional monitoring.

Security knows no timetables, and neither do we. Our technical team and the Alarm Reception Centre supervise your security systems 24 hours a day, every day of the year.
If something happens, we act immediately. With Dumo Security, you are never alone.

Each property is unique, so we analyse access points, vulnerabilities, usage habits and the level of risk in the area to design a fully customised security system adapted to your needs.
Our goal is to create security systems that really protect, without off-the-shelf solutions or generic kits.

Our professionals are constantly trained to master new technologies and perform according to the most demanding protocols.
We install security systems in compliance with regulations and guarantee the best performance from day one. We also manage breakdowns, false warnings, mandatory revisions and any incident that may affect your protection.
Our security systems services are designed to cover all security needs for homes, businesses, communities and industrial facilities.
Each service can be contracted independently or integrated into a complete system that maximises protection and simplifies management.











If you are looking to improve the security of your home or business, contact us and in less than 24 hours a technician will analyse your case.
Dumo Security was born in 2006 with the aim of offering complete electronic security solutions for individuals and companies in Barcelona. Since our beginnings, we have evolved from the installation of basic alarms to become a security systems company with comprehensive solutions that covers different services focused on personal and material protection, such as Alarm systems in Barcelona, Video surveillance in Barcelona, Access Control, Fire Detection, Anti-Theft, Anti-Theft, etc...
Our work philosophy is based on three fundamental pillars: trust, transparency and proximity. Each customer receives close and personalised treatment, honest technical advice and a real commitment to support throughout the useful life of the system. To this we add a constant commitment to technological innovation, always incorporating the most advanced and reliable devices on the market.
We are approved by the Directorate General of Police (DGP No 3805) for the installation and maintenance of systems connected to an Alarm Receiving Centre, and we have the registration RECI-005005218 which qualifies us for the installation and maintenance of fire protection systems. In addition, we are certified ISO 9001 which guarantees our quality standards in all processes. These official certifications guarantee our technical capacity and compliance with all sector regulations.
From our headquarters in Badalona we cover the entire city of Barcelona, the metropolitan area and the main towns in the province, guaranteeing fast response times for new installations as well as for maintenance and urgent technical assistance.
Of course. Once you contact us by email, telephone or by filling in our form, in less than 24 hours a specialised technician will come to your home, business or community to analyse all the accesses and vulnerable points and propose the most suitable security system, explaining all the available options. The advice is free and totally personalised.
It depends on the type of system you choose. Wireless security systems do not require any building work or wiring, they are installed by means of sensors and cameras that work by radio frequency and battery, which allows a quick and agile installation.
Wired systems do require running cables through ducts or trunking, although in many cases existing installations are used. We also offer mixed systems that combine both technologies to optimise cost, reliability and aesthetics. Our technicians will advise you on the best option for your case.
We offer various payment methods adapted to each client. You can purchase the complete equipment in a single payment, finance the installation of the security system in easy monthly instalments, or contract the service through technological leasing that allows you to have a complete security system without initial investment, with easy monthly instalments that include equipment, installation, maintenance and connection to CRA. Contact us and we will explain all the payment options we offer so that you can choose the one that best suits your situation.
Yes, preventive maintenance is a fundamental part of our service. All our security systems include scheduled reviews in which we verify the correct operation of sensors, cameras, control unit and communications, update the firmware when necessary, check batteries and carry out the mandatory technical tests. In addition, we offer 24/7 technical assistance service to resolve any incident or breakdown that may arise.
All the equipment we install comes with a manufacturer's guarantee that varies according to the type of device (normally between 2 and 5 years). We also offer an additional warranty on the security installation carried out by our technicians, covering any assembly or configuration defects.
During the warranty period, any breakdown or malfunction related to the equipment or installation will be repaired or replaced at no additional cost to the customer, provided there is no mishandling by the customer, vandalism or tampering by non-Dumo Security personnel.
Absolutely. Dumo Security is approved by the Directorate General of Police (DGP No 3805) for the installation and maintenance of systems connected to Alarm Reception Centres, complying with all current private security regulations. We also have the RECI-005005218 registration which qualifies us to install and maintain fire protection systems in accordance with the Fire Protection Installations Regulations (RIPCI). All our installations comply with the applicable legislation and are properly documented with official certificates and bulletins.
Not necessarily. Many of our security systems can operate autonomously without an internet connection, communicating with the Alarm Reception Centre via the system's own GPRS SIM card. However, internet connection provides important advantages that improve remote access in real time from the mobile app, camera viewing from anywhere, instant push notifications and faster image transmission speed. We will advise you on the most suitable configuration for your case.
Yes, we install all three types according to the needs of each project. The installation of wireless security systems is perfect for homes already built where there is no need for building work, they offer quick installation and clean aesthetics. Wired systems are ideal for new installations or complete renovations, they provide maximum reliability and do not depend on batteries. Mixed systems combine the best of both technologies, using wired for critical fixed elements and wireless for areas where wiring is difficult. Our technicians will recommend the best option after assessing your space.
It depends on the modality you choose. We have options both with and without permanence, adapting to the needs of each customer. We explain the different alternatives available so that you can choose the one that best suits your situation and preferences.
The installation time for security systems in Barcelona varies according to the complexity of the project. A standard home with an alarm and 3-4 cameras can be installed in 2 or 3 days. Businesses or communities with a larger number of points to protect may require between 2 and 5 days of work.
Wireless security systems are quicker to install than wired ones. In any case, we provide you with a detailed schedule before you start so that you can get organised without any surprises.
Yes, in most cases it is possible to move your security system in Barcelona to a new location. Wireless systems are particularly easy to relocate, as they require no building work and can be uninstalled and reinstalled in the new space with minimal modifications. Wired systems can be partially relocated (switchboard, IP cameras, keypads) although some of the wiring will remain in the original location.
Our technical team will carry out an assessment of the new space, adapt the existing system to the needs of the new location and complete the reinstallation in a professional manner.
