Intrusion detection with a defined response.
S4 designs and integrates intrusion detection and alarms by zones and perimeters: sensors suited to each environment, panels with dual-path communication, video verification and written response protocols, so that every alarm leads to an action and not to noise.

Who it is for
4 layers, from detection to response. Choose a profile to see which part of the system concerns you.
Head of security
Reliable alarms and a response that does not depend on improvisation.
Operations director
Warehouses and sites protected outside working hours.
Co-owned building administrator
Common areas, equipment rooms and perimeter under control.
Alarms nobody believes in anymore.
A system that gives false alarms daily ends up disabled or ignored. And a perimeter without detection only warns you once the intruder is already inside.
You need it if you recognize any of these signs:
- False alarms are frequent and staff no longer react.
- Parts of the system are disabled for convenience.
- Nobody has written down who responds to an alarm or how.
- The outer perimeter has no early detection.
- There is no way to confirm with an image what triggered the alarm.
How the system is built.
The panel integrates with video surveillance (a camera linked to each zone) and with access control (arming and disarming depending on who leaves last and who arrives first). Panels with IP communication and a backup path ensure the signal gets through even if one channel fails.
Detection
- Motion and dual-technology sensors
- Magnetic contacts, vibration and glass-break sensors
- Infrared barriers, fence sensors or perimeter analytics
- Panic buttons
Panel
- Zones and partitions
- IP communication and cellular backup path
- Backup batteries
Verification
- Camera linked to each zone
- Alarm management software
- Arming by schedule or by user
Response
- Protocol per event type
- Notification of responsible staff
- Link to the monitoring center you choose
What is included and what is not.
Included in the service
- Risk analysis and zoning of areas and perimeter
- Sensor selection according to the environment: indoor, outdoor, dust, animals, air currents
- Supply, installation and programming of the panel and sensors
- Video verification and integration with other systems
- Response protocols written with your team
- Zone-by-zone testing and training
Out of scope
- Response by staff or guards
- Monitoring center service: we integrate it with the provider you choose
- Physical enclosures (walls, fences, razor wire)
Anything out of scope is coordinated with the right party or quoted separately, and is always stated in writing before we start.
How we do it, step by step.

DeliverableEvent and root-cause report
Reference regulations and standards.
These are the usual references for this type of system. The technical report of each project identifies which ones apply, depending on the use, size and location of the installation.
Regulatory reference, indicative
- EN 50131
- European series of intrusion alarm standards, with security grades 1 to 4; design reference when the project requires it.
- Law 1581 of 2012 and Decree 1377 of 2013 (Colombian data protection)
- If verification uses video, the images are treated as personal data.
- RETIE
- Colombian technical regulation for electrical installations: governs the service connections and circuits that power the equipment.

How we apply it in your sector.
What people ask us most.
How are false alarms reduced?
With zone-based design, sensors suited to the environment, careful installation and image verification. Each false alarm is analyzed to correct its cause.
Is it monitored 24 hours?
It is defined in the design according to your operation: the alarm can go to your team, to an external monitoring center, or both. We integrate the signal with whoever you choose.
What happens if the line or the power is cut?
The panel has a backup battery and communicates over two paths, IP and cellular; the loss of one raises a notice.
What is video verification?
When a zone is triggered, the operator receives the image from the linked camera and confirms the intruder before dispatching anyone.
Does it work outdoors?
Yes, with infrared barriers, fence sensors or perimeter analytics. The choice depends on terrain, vegetation and wildlife.
