About Dumo Security

Dumo Seguridad is a company specialising in security systems for homes, businesses and communities, based in Badalona and operating nationwide. Since 2006, we have been designing, installing and maintaining professional security systems that protect people, businesses and facilities, with an approach based on technical reliability, transparency and friendly service. Our objective is simple: that our clients can live and work with peace of mind, knowing that their security is well thought out, correctly installed and backed up by a professional team available when they need it.

Who we are and what we do

Dumo Seguridad S.L. is a security systems company founded in 2006 and located at Carrer de l'Electrònica, 9, 08915 Badalona (Barcelona). We are dedicated to the installation and maintenance of electronic security systems, including intruder alarms, video surveillance, access control, fire detection, key escort and custody service, maintenance and breakdown service and advanced protection solutions for residential, business and industrial environments. We work throughout the province of Barcelona and serve both private clients and companies, neighbourhood associations and public entities, always with a professional approach and adapted to each specific situation.

Actual experience in security systems

Dumo Seguridad has 19 years of experience in the security sector. The company was founded by David Durà Castellano y Iban Moreno Teba, both with a previous experience of approximately 10 years in a leading and pioneering company in electronic security such as ADT and Sensormatic.
The beginnings were modest, two people, one focused on the commercial side and the other on the technical side, working from a small warehouse. Over time, the company has grown steadily to become a team of 9 professionals, with its own facilities including 150 m² of warehouse and 150 m² of offices.

Types of projects and environments worked on

Over the years we have mainly carried out security projects in:

  • Single-family houses and flats
  • Companies and businesses
  • Industrial buildings
  • Neighbourhood communities
  • Plots and sites with specific protection needs

This experience in real contexts allows us to anticipate risks, design appropriate solutions and avoid common mistakes in poorly planned installations.

Our understanding of security

  • An approach based on professional judgement

    At Dumo Security we take security seriously. For this reason, there are some things we do not do, even if we are asked to do them. We do not carry out improvised installations or partial solutions that do not guarantee a real level of protection. We do not work with low-quality equipment or configurations that create a false sense of security. Nor do we recommend poorly dimensioned systems or systems designed only to “comply”, if we consider that they do not provide effective long-term protection. We prefer to reject a project rather than implement a solution that we do not fully trust.

  • What we prioritise in each installation

    When we install a security system, our primary concern is that it is well designed from the outset. This involves:Properly protecting all accesses and critical points, guaranteeing optimum system operation, verifying that communications with the Alarm Receiving Centre (ARC) are correct and ensuring that the client fully understands how their system works.Real security depends not only on the equipment, but also on how it is designed, installed and used.

How we approach a security project

Legality, approvals and regulatory compliance

Dumo Seguridad S.L. is an officially authorised company and strictly complies with the regulations of the private security sector in Spain.

In the field of video surveillance, we comply with the GDPR, the LOPDDGDD and the guidelines of the Spanish Data Protection Agency, advising each client on the legal use of cameras, signage, image preservation and access to recordings.

Regulatory compliance is a top priority in our work.

Maintenance, support and incident response

Security does not end with the installation. That's why we offer preventive, corrective and comprehensive maintenance services.

These services help to prevent failures, reduce breakdowns and ensure that the system performs correctly when needed.

In addition, we have 24/7 technical support, with on-call service and rapid response to incidents, even in the early hours of the morning.

Our clients and project types

We work mainly with companies, individuals and communities of neighbours.

We tend to reject projects based solely on low-cost alarms, as they do not fit with our real security philosophy.

Our customers especially value the close and transparent treatment, the speed of installation and support, the quality and reliability of the systems and the peace of mind provided by the service.

Why trust Dumo Security

Because we are a close company, with a stable and experienced team, that does not sell for the sake of selling.

We advise, explain and accompany each client so that they can make the best decision based on their real situation. We offer customised solutions, high quality systems and a fast and accessible after-sales service.

Trust is built on deeds, not promises.

Everyone talks about prosegur and other companies, this is one of the most transparent companies I have seen:
First, top quality material (Ajax devices).

Second, full transparency, you must register in the application of the devices and Dumo is the one who manages everything, then if you decide to leave for whatever reason, you keep control of the devices and you manage them yourself (they do not become obsolete or blocked as in other companies).

Thirdly, human work, great salesmen and technicians willing to invest time to solve all your doubts.

Highly recommended!

The treatment is unbeatable, the quality of the products is very good, and we loved the speed and above all how neat and clean they were working, plus how well they explained how the apps worked, the alarm, everything ... I give them 5 stars because we can not put more!
Very good professionals, a very good experience to have contracted with them, the alarm of my parents' flat.

Fantastic team and attention. I asked for a project and in 5 minutes I had it. I told them I needed to alarm the house the next day with only a few hours notice and they did it. The technicians were very friendly, efficient and very experienced. They explained everything to us in a very friendly manner. I recommend them 100%. Personal and friendly service.
