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.

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.

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.
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.

Every project begins with an initial contact by phone, WhatsApp, email or web form. In this phase we collect basic information about the space, access, opening hours and the client's main concerns.
Subsequently, we carry out an on-site technical visit, where a specialised technician analyses the environment, identifies vulnerable points and studies the best configuration of the system. This study is free of charge and without obligation.
Behind Dumo Security there is a stable team of professionals with real experience in the electronic security sector.
Final technical decisions on projects are made by David Durà and Xavi Corominas, The company guarantees coherence and technical responsibility in each installation.
