At Dumo Seguridad we design and install squat alarms in Barcelona specialised in protecting empty homes, second homes and uninhabited properties. Our anti-squatting system includes perimeter detection, immediate mobile phone notification in the event of forced access attempts and connection to a 24/7 Alarm Reception Centre.
We protect your property against squatting, burglary and unauthorised access by taking action within the first few hours. Our anti-squatting alarms work for up to 12 months without a power connection thanks to their long-lasting battery.
In Barcelona, empty dwellings are frequent targets for squatters. Dwellings that are left exposed for weeks without supervision. Second homes that can be occupied for months without the owner's knowledge. Inherited flats in the process of being sold or homes rented between tenants are especially vulnerable during these empty periods.
Recovering a squat can take months or even years, with very high financial, legal and emotional costs. A squatter alarm prevents these situations through immediate detection of access attempts, a siren that alerts the neighbourhood and an early warning that allows you to act when the occupant has not yet settled in the home.
At Dumo Security we have different anti-squatting system options depending on the needs of each home. From basic anti-squatting alarms with opening sensors to complete perimeter systems with video verification using MotionCam technology and triple channel connectivity that guarantees communications even if cables or internet are cut.
Squatters gain access to empty houses by forcing doors or changing locks without anyone knowing for days. Homeowners who live in another city discover the squat when it is too late to act.
Our burglar alarms in Barcelona combine perimeter sensors, magnetic sensors on doors and windows, motion detectors with Pet Immunity technology, vibration sensors on windows and an outdoor siren. When unauthorised access is detected, you receive a notification on your mobile phone while the siren alerts your neighbours.
Acting in the first few hours is key to preventing squatters from taking up residence.
You can control access to your home with anti-squatting alarms in Barcelona 24 hours a day from anywhere. The system also sends push notifications, SMS or calls to your mobile phone when it detects forced access, interior movement or door tampering.
This functionality is critical in second homes, inherited flats or homes for sale where you may be in another city. You receive the warning in real time, you verify what is happening through cameras if you have them installed and the action protocol is activated.
With a squatter alarm you act in minutes, not days.
Recovering an occupied property involves legal proceedings that can last from 6 months to 2 years. Added to this are lawyers' fees, losses due to non-payment of utilities that remain in your name, damage to the property, the impossibility of selling or renting during the process and the loss of market value.
Our anti-squatting alarms in Barcelona detect and stop the attempt in the first hours avoiding all this. They prevent them from establishing a legal address, which greatly simplifies any subsequent action.
The investment in burglar alarms is minimal compared to the actual cost of repossessing an occupied dwelling.
Video verification of squatter alarms reduces false alarms and provides evidence when a breach occurs. You can check from the app what is happening before activating the protocol, which speeds up the response and provides documentary evidence of the attempt.
CCTV cameras enable real-time verification in compliance with data protection regulations with visible signage and restricted access. Images as evidence significantly improve the ability of police to act.
Our professional squatter alarm with Ajax technology is designed specifically for uninhabited dwellings. It is a set of Grade 2 certified devices that monitor the vacant property 24 hours a day. When it detects attempted access, forced entry, interior movement or tampering, it sends immediate alerts to the owner and the ARC.
This security system is designed for empty homes where any activity is potentially an occupation. It incorporates anti-sabotage protection so that the anti-occupancy home alarms continue to work even if an attempt is made to override them.
The brain of our anti-squatting security system is the Grade 2 certified Hub 2 central controller. It receives signals from up to 100 devices, validates if it is a real event and activates sirens or notifications if necessary.
Includes long-life battery with autonomy of up to 12 months without electrical connection using 3,200 Wh zinc-air technology, ideal for empty homes or second homes. It has anti-sabotage protection, management of both perimeter and interior zones and complete event logging.
Our anti-squatting alarms in Barcelona are connected to a CRA, which manages the communication with the operators after an alarm is triggered.
The Hub 2 communicates via triple channel Ethernet + dual SIM (2G/3G/4G), ensuring that the alarm notification is sent even if there is no fixed internet or if connection cables are cut.
This connectivity ensures that the anti-squatting system will always be operational and will be able to send alerts to the landlord and the ARC, regardless of squatters attempting to sabotage communications.
Jeweller and Wings wireless protocols ensure robust security and tamper detection, including anti-inhibit, anti-masking and tamper.
Our motion detectors with PIR (passive infrared) technology detect any human presence inside the home and trigger the anti-squat alarm immediately.
Pet Immunity technology prevents false alarms caused by pets by differentiating between the movement of pets and people, making the anti-squatter system more reliable and reducing unnecessary alerts.
Magnetic opening sensors are installed on doors and windows to detect the exact moment when an access is opened.
They are the first line of defence of the anti-squatting system, as they alert the moment squatters attempt to force open any door or window, before they even enter the home. This early detection is key to activating sirens and sending warnings while the squatting attempt is in its initial phase.
MotionCam PhOD detectors combine a motion sensor with an integrated camera to capture photographic images at the exact moment an intrusion is detected.
Visual verification allows immediate confirmation of a real attempt at occupation, facilitating the response of the CRA and police action. Images are sent instantly via the Ajax Security app even over a 2G connection, guaranteeing the receipt of visual evidence.
High-powered sirens (105 dB) are activated when a squatting attempt is confirmed, generating a powerful sound signal that alerts neighbours in the building or area and deters squatters.
Outdoor sirens also have a visual deterrent effect, as their visible presence from the street warns potential squatters that the dwelling is protected. In many cases, the activation of the siren alone is enough to make squatters leave the house before settling in.
Outdoor detectors are installed in perimeter areas such as gardens, terraces, patios or outside entrances to detect the presence of intruders before they reach doors or windows.
These sensors extend the protection of your anti-squatting system by creating a security perimeter that alerts you in the early stages of a break-in attempt. They are especially useful in villas, ground floor apartments with courtyards or homes with vulnerable exterior access.
Our anti-squatting system can integrate smoke and flood detectors to protect the home not only against squatting, but also against fires and water leaks that could cause serious damage to an uninhabited property.
These sensors send instant alerts to the homeowner via the Ajax Security app, allowing them to act quickly in case of emergencies even when away from the home.
The Ajax Security app (iOS/Android) allows the owner to arm and disarm our squatter alarms in Barcelona, manage up to 100 sensors, create and manage users with different access levels and receive instant notifications of any event.
The app provides full remote control of the system from anywhere in the world, allowing the status of the empty home to be monitored in real time. It includes the "ALWAYS WITH YOU" functionality that allows sending SOS with geolocation, providing additional security when the owner is away from home.
The anti-squat home alarms work in a coordinated manner to detect squatting attempts at an early stage, alert the owner in seconds and activate an immediate response that prevents squatters from establishing themselves in the home. It combines perimeter and interior sensors, a reinforced central unit, high-powered sirens and redundant communications to always act in time.
You activate the anti-squatting system in full mode before you leave. The system is permanently armed and any access or movement triggers the anti-squatting alarm automatically.
When someone tries to break in through the front door, gain access through a window, break glass or open a balcony, the perimeter sensors of the squatter alarms send a signal at that instant. This early detection before they enter is key to stopping squatting at an early stage.
The system works with two protection barriers depending on the type of home. The first barrier protects the outer perimeter, while the second barrier detects interior movement if they gain access.
The central panel of the squatter alarm validates the information before activating the sirens. In vacant dwellings, any activity is suspicious, but the control panel validates that the pattern corresponds to real human access before triggering the response.
This reduces false alarms from animals or environmental factors.
When the attempt is confirmed, the external sirens of our squatter alarms in Barcelona are activated with a high intensity sound signal. The siren alerts the neighbours, generating immediate social pressure and making them leave the house before settling in.
Simultaneously, the anti-squatting system sends an instant alert to your mobile phone via push notification, SMS or call. When the anti-squatting alarm is connected to the ARC, an operator receives the signal and starts the verification protocol.
This real-time warning allows you to act within minutes even if you are in another city.
The Central Receiving Centre of the anti-squatting alarms in Barcelona verifies the event by means of cameras if they exist, contacts you to confirm that it is not a legitimate visit and activates the protocol for notifying the security forces if the attempt is confirmed.
This coordinated response improves the ability to act early before they become established in the dwelling.

Attention 24/7We have been working for almost two decades protecting second homes, empty flats and inherited homes in Barcelona and the metropolitan area with anti-squatting alarms. We have installed hundreds of anti-squatting systems.
We know how they operate and how the issues have changed.
We work with professional anti-squatting systems designed for uninhabited homes, not generic kits. We work with approved devices with communications (GSM/GPRS/4G and Wi-Fi) that work even if they cut cables.
The systems include long battery life, highly sensitive perimeter sensors, mobile app integration and the ability to add video verification to your squatter alarm.
We offer 24-hour service for your squatter alarm, which is essential when you receive an alert when you are away from Barcelona. We have fast response times and permanent telephone availability.
We carry out preventive maintenance of occupancy alarms in Barcelona and periodic reviews. We not only install an alarm to prevent squatters, we accompany you throughout the time your home remains uninhabited.
Before installing any home alarm for squatters, we analyse different factors such as the type of property, vulnerable access, the area and the level of squatting in the neighbourhood. We also assess how long it has been vacant and whether it has neighbours or a doorman.
We design a customised anti-squatting system. We will select the type and number of sensors for your squatter alarm, the strategic location of external sirens for maximum deterrent visibility, the configuration of the arming mode and offer you additional anti-squatting security recommendations. We do not sell standard squatter alarm packs, but specific solutions according to the actual level of vulnerability.
The installation of anti-squatting alarms in Barcelona is carried out by our own technicians specialised in protection against squatting. We know the weak points that squatters exploit, we know where to place sensors and sirens to maximise the effectiveness of our anti-squatting home alarms.
We make installations discreet but with visible deterrents and explain how to act in the event of a real alert.

Immediate eviction cannot be guaranteed because it depends on legal and police factors. What a squatter alarm does guarantee is to detect the attempt within the first few hours and allow action to be taken before they establish a legal address. Providing verification through images with your anti-squatting system, activating an immediate warning protocol and coordinating response with CRA significantly improves the capacity for early action, which is decisive in avoiding lengthy legal proceedings.
Yes, squatter alarms in Barcelona are specifically designed for empty homes.
It is important to clarify the legal difference: trespassing (art. 202 PC) applies when the dwelling has furniture or occasional use, while usurpation (art. 245.1 PC) refers to empty properties.
With the reform of 2025 (LO 1/2025, in force since 03/04/2025 and Circular FGE 1/2025), both usurpation and trespassing can be processed by rapid prosecution if they meet the requirements of art. 795 LECrim. An anti-occupation alarm does not change the law, but it does help to detect quickly, document by verification and act in the first few hours, which drastically speeds up the deadlines even in cases of usurpation.
The anti-squatting system sends an immediate warning when it detects forced access or interior movement. The notification of your anti-squat alarm reaches your mobile phone immediately by push, SMS or call. As it is connected to the ARC, the control panel receives the signal simultaneously and starts the verification protocol. The detection and initial warning of anti-squatting alarms in Barcelona are instantaneous.
The price of the anti-squatting alarm varies according to the number of accesses to be protected, if it includes video verification, if you need perimeter protection outside or only inside.
We carry out a study where we define the necessary anti-squatting system and we give you a closed budget. Request your free study to find out the price of a specific anti-squatting alarm for your case.
Yes, all our anti-squat alarms have a built-in battery back-up that keeps the anti-squat system operational for up to 12 months without electrical connection, ideal for empty homes or second homes.
Our squatter alarm can operate completely without power supply by means of long-life battery backup. Redundant communications (4G/GSM/GPRS) continue to send alerts even if power and internet are cut. The system detects the power cut and sends notification.
We work with different types of contracts for anti-squatting alarms in Barcelona. During the study we explain all the alternatives so that you can choose the one that best suits you. There is no small print or hidden penalties.
The capacity for police action depends on the case and the stage at which it is detected. The decisive thing is to act as soon as possible and with verification. An anti-occupation alarm that detects the attempt within the first few hours provides image evidence, which significantly improves the chances of rapid action.
The professional anti-squatting systems we install incorporate signal inhibition detection. If someone tries to block your alarm communications to prevent squatters using jammers, the system detects the anomaly and sends a failure warning before losing contact. By working with triple channel (Ethernet + dual SIM 2G/3G/4G), if they inhibit one frequency the system remains operational on the other. Redundancy in communications and autonomous battery power supply make it very difficult to completely override our anti-squatting system.
