S4 Security, home Request an assessment

Security and workplace technology, designed with judgment.

We design, integrate and operate your security and workplace technology. We start by understanding your operation, not by selling equipment.

Cross-section of a building with cameras and their field of view, access readers, Wi-Fi points, sensors and an equipment room where all the cabling arrives
Fig. 1 Cross-section of a building: every system reaches the same equipment room.

More than 600 projects since 2017.

S4 was founded in Bogotá in 2017, Colombian-owned and with its own team. We work for organizations across Colombia and measure results against shared objectives.

Before we talk about equipment, here is what you are facing.

Every project starts with a sentence like these. We turn it into a measurable design.

Fig. 2 Scroll the list: the plan shows which design solves each problem.

  1. “We have cameras, but nobody watches what they record.”

    Objective-based video surveillance, with analytics that flag what matters.

    Video surveillance and analytics

  2. “We do not know who comes in, through which door or at what time.”

    Profiles, schedules, visitors and a log of every event.

    Access control

  3. “Alarms go off so often that nobody pays attention anymore.”

    Zones, video verification and a protocol that says who acts.

    Intrusion and alarms

  4. “The Wi-Fi fails right in the meeting room.”

    We measure coverage and capacity before choosing equipment, and again when we finish.

    Wi-Fi and communications

  5. “The rack is a tangle of cables nobody dares to touch.”

    Labeled, certified cabling with up-to-date drawings.

    Data center and equipment room

  6. “If the server fails tomorrow, we do not know what we would recover.”

    Backups sized to how much you can afford to lose, with restore tests.

    Backup and continuity

Two pillars, one standard.

Protection and daily work share cabling, network and equipment room. We design them together.

And what surrounds the building: capabilities that complete the pillars when the project calls for it.

Also, two product lines of our own.

One to save on licenses, another to sell digitally.

Five steps, each with its deliverable.

You decide at each step with a document in front of you, not a promise.

  1. Assessment

    We visit the site, survey what is there and analyze risks and operations.

    Deliverable: assessment report

  2. Design

    Architecture, regulatory compliance and a phased budget, before buying anything.

    Deliverable: technical report and phased plan

  3. Integration

    Supply and installation of interoperable brands.

    Deliverable: installed and configured system

  4. Commissioning

    Testing, documentation, training and operating protocols.

    Deliverable: test report and documentation

  5. Operation and improvement

    Support, maintenance and indicators.

    Deliverable: service reports

Why S4.

In more than 600 projects, the failure was rarely in the equipment. It was in how it was integrated and who responded afterwards.

Assessment before catalog
We first understand your operation. The brand is chosen per project and justified in the technical report.
Regulatory criteria in writing
The technical report identifies the regulations that apply to your building and its use.
Systems that talk to each other
Access with video surveillance, alarms with verification, lighting integrated into the building BMS.
One point of contact from start to finish
From consulting to support, without changing teams.
Everything is documented
Drawings, labeling, certification of every network point and test reports.
Measured service
Response times and indicators agreed in writing.

Where would your assessment start?

Three questions, no personal data. With each answer, the diagram marks the systems we would review.

1 of 3What type of site?
2 of 3What worries you most today?
3 of 3About what size?

With your three answers, we will tell you where we would start.

Your answers carry over to the contact form; we only need a way to reach you.

What people ask us most.

All frequently asked questions

What is the assessment and what do I receive?

It is the first step: a site visit, survey and analysis of risks and operations. You receive a report with findings and prioritized recommendations.

How much does a project cost?

It depends on scope, site size and requirements. The assessment defines them, and the phased budget comes from there.

Do you only work in Bogotá?

We serve projects across Colombia from our base in Bogotá. Contact us with the details of yours.

Do you operate what you install?

Yes. Support, maintenance and indicators are the fifth step of our methodology.
