Video surveillance by objective, not by camera.
S4 designs, integrates and operates IP video surveillance with video analytics in Colombia. We define what must be seen, in what detail and for how long; then we size cameras, recording, network and control center, and deliver it tested and documented.

Who it is for
4 layers, from field to operation. Choose a profile to see which part of the system concerns you.
Head of security
Needs useful evidence and alerts on what matters, not more screens to watch.
Operations director
Wants to see the status of warehouses, loading docks and sites, and reduce losses and incidents.
Co-owned building administrator
Looks for a system the administration can operate and justify to the owners' assembly.
Many cameras, little useful evidence.
After an incident, the face can't be made out, the license plate is washed out by backlight, or the recording has already been overwritten. And nobody can watch dozens of monitors at once.
You need it if you recognize any of these signs:
- Recordings do not allow people or license plates to be identified.
- Actual retention is shorter than your internal policy requires.
- Equipment from several manufacturers that can't be seen from one platform.
- Staff review hours of video to find a single event.
- Video surveillance notices or an image-handling policy are missing.
How the system is built.
We work with ONVIF- and H.264/H.265-compatible cameras and software, so you can grow with equipment from several manufacturers and integrate access control, intrusion and fire systems. If an integration requires a specific manufacturer, the technical report explains why.
Field
- Fixed, dome and PTZ cameras
- Thermal or license-plate-recognition cameras when the objective calls for it
- Infrared illumination and outdoor protection
Transport
- PoE switches and a segmented video network
- Fiber or wireless links for long distances
- Backup power (UPS)
Platform
- NVR recorder or VMS server
- Analytics on the camera or on the server
- Storage sized by retention
Operation
- Control center and video wall
- Real-time alerts and mobile access
- Evidence export with traceability
What is included and what is not.
Included in the service
- Risk analysis and objective for each camera: detect, recognize or identify
- Coverage design on floor plans, with optics and mounting height
- Calculation of storage, retention and bandwidth
- Supply, cabling, installation and configuration
- Analytics configuration and alert rules
- Day and night testing, documentation and operator training
Out of scope
- Human surveillance or security guards
- Permanent monitoring from an external central station, which we integrate with whoever you choose
- Major civil works (underground conduits, tall poles), quoted separately
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.
-
Assessment
Day and night visit, inventory of what exists and agreement with you on the critical points and what is expected to be seen at each one.
DeliverableRisk report and objectives map
-
Design
Coverage per camera, level of detail, recording and network calculations, and platform architecture.
DeliverableTechnical report, floor plans and phased plan
-
Integration
Installation, platform and analytics configuration, and integration with the other systems.
DeliverableSystem installed and configured
-
Commissioning
Verification of each camera against its objective, day and night; testing of alerts, recording and export; operator training.
DeliverablePer-camera test report and operating manual
-
Operation and improvement
Preventive maintenance, review of disks and cameras, analytics tuning and operator support.
DeliverablePeriodic status reports
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
- Law 1581 of 2012 and Decree 1377 of 2013 (Colombian data protection)
- Images of people are personal data: they require notice, a defined purpose, a data-handling policy and restricted access.
- SIC video surveillance guidelines
- Guidance from the Colombian Superintendence of Industry and Commerce (SIC) on cameras, notices and image retention.
- IEC 62676
- International video surveillance standard; reference for setting the level of detail for each objective.
- ONVIF
- Interoperability between cameras, recorders and software from different manufacturers.
- 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 many cameras do I need?
It depends on the surveillance objectives, not on the area: identifying faces at an entrance requires a different camera and height than detecting movement in a parking lot. The assessment sets the objectives and the quantity follows from them.
What is video analytics?
Software that interprets the image and generates alerts: a person in a restricted area, a vehicle stopped where it should not be, the crossing of a virtual line. It lets you act on what is relevant without reviewing hours of recordings.
How long should recordings be kept?
As long as your data-handling policy sets, based on the purpose of the cameras. We size the disks for that period: longer period, more storage.
What does Colombian law require for security cameras?
Images of people are personal data (Law 1581 of 2012): you must post visible notices, define the purpose, have a data-handling policy and restrict access to recordings.
Can you reuse the cameras I already have?
Often, yes. The assessment reviews their condition and compatibility; ONVIF cameras can usually be integrated into a new platform.
Can I view the video from a mobile phone?
Yes, with secure, profile-based access: each user sees only the cameras assigned to them.
