In Marbejer Security we use external detection as first line of defenceintegrated into a global safety design and adapted to the real conditions of each environment.

Active infrared barriers (issuer + receiver)

Perimetral detection systems based on active infrared barriersdesigned to create invisible protection lines on the outside.

Key characteristics:

High immunity from false alarms
Disqualification sign for adverse environmental conditions
Close and controlled detection area
Easy adaptation to the field and architecture
Minimum maintenance

These barriers are ideal for perimeter closures, fences, walls and external accesswhere precision is critical.

External detectors

The external photodetectors are the ideal solution to protect facades, gardens, accesses and perimeters of housing and business, maintaining security without limiting the normal use of space.

This type of detector allows continuously monitoring outside areas, detecting any movement that disrupts your beam of light or infrared, even under low visibility or at night.

The system works by a active light or infrared sensorwhich immediately activates the alarm in the presence of intruders, offering preventive protection at critical access points.

Its weather-resistant design allows installation outside, ensuring a effective and discreet protection without affecting the aesthetics of the property.

With the outside photosectors, you can protect gardens, entrances and perimeters, maintaining the freedom of use of space and enjoying total tranquility at any time of the day or night..

PIR Detectors Type Curtain

Curtain-type PIR detectors are the ideal solution to protect external windows and access without limiting the normal use of space.

This type of sensor allows to set up the security system with open doors and windows, being especially useful in housing and business where there are frequent transit or constant ventilation.

The system works by a "invisible curtain" of detection: any movement that crosses the line activates the alarm immediately, offering a rapid response to potential intruderseven before they try to force the entrance.

Its versatile design allows the installation both in interiors as outsideensuring effective and discreet protection at critical points of access, without affecting the aesthetics and functionality of your home or business.

With the curtain-type PIR detectors, you can keep windows and doors open without compromising securityenjoying comfort and protection at the same time.

Double-tech sensors: the most reliable protection for outdoor

A dual-tech sensor uses two additional detection systems normally PIR (passive infrared) and microwave, to make sure that only the moves Intruder real cause an alarm. This combination significantly reduces false alarms, which are often a common problem in simple sensors.

1. False alarms reduced to a minimum

Thanks to advanced digital signal analysis (SMDA) and simultaneous confirmation of PIR and microwave, the sensor is only fired when both detect a real intruder. This prevents animal-caused activations, shadows or sudden temperature changes.

2. Comprehensive and stable coverage

With detection ranges of up to 12 m and 90 ° angle, these sensors cover outdoor access areas such as gardens, entrances, facades and corridors without blind spots.

3. Anti-masking technology
Advanced models incorporate anti-masking detection, which means that if someone tries to cover or block the sensor, this is also detected and an alarm is generated.

4. Resistant design for outdoor
With classification IP55, these detectors are designed to withstand rain, dust and climate changes, offering constant protection 24 hours a day.

The outside detection does not only seek to warn: it seeks dissuade the intruder, reduce their time for action and increase the chance of attempt abandonment before the attack goes on.
