On many Tunisian sites, the security room is a space where a video screen, an access control PC, a fire panel and an intrusion keypad pile up, each with its own alarms. When an incident happens, the operator has to cross-check everything alone. This guide explains how to design a control room and PSIM hypervision that turn scattered signals into fast decisions.
Why a real control room
A night intrusion alarm at an industrial site in Sfax, a forced door in a bank branch in Tunis, a fire in a warehouse in Ben Arous: in each case, the quality of the response depends on what the operator sees in the first seconds. Without a structured control room, they juggle software, miss alarms buried in noise and leave no usable record. A well-designed room cuts verification time, standardises the response and produces an auditable history.
What is a PSIM?
PSIM — Physical Security Information Management — is a software layer that connects to every security and technical system on a site. It collects their events, correlates them, displays them on a map or floor plan and proposes the procedure to follow. It is the core of our supervision and hypervision offer.
VMS, hypervision, PSIM: who does what
The VMS
It manages cameras, recording, playback and video analytics. It remains essential, but it only knows video. See our video surveillance guide for Tunisia.
Hypervision
It aggregates several systems or sites on one interface, with maps and dashboards. It is the big picture.
The PSIM
It adds logic: correlation rules, guided procedures, logbook, reports. A badge refused three times followed by a perimeter detection nearby is no longer two separate alarms but one qualified incident, with the nearest camera already on screen.
Guided procedures and correlation
This is where the operational gain lies. For each event type, the PSIM runs the steps agreed with the security management:
- automatic display of the zone's cameras and the building plan;
- qualification questions (real intrusion, false alarm, maintenance);
- actions from the console: lock a door, trigger a siren, dispatch a patrol;
- call and escalation list (site manager, civil protection, police);
- time-stamped closure with comments, snapshots and report export.
The result: a night operator applies the same response as an experienced shift leader, and management gets real indicators (alarm count, false alarm rate, handling times).
Control room architecture
The video wall
Narrow-bezel LCD or LED panels depending on size and viewing distance, driven by a controller showing maps, video and dashboards. It provides shared situational awareness, not individual handling.
Operator desks
Technical furniture designed for continuous operation, two to four screens per desk, KVM switching between systems, integrated intercom and radio.
The technical room
PSIM and VMS servers, storage, network, UPS and cooling, kept apart from the operator room for noise and heat. See our control room and data centre fit-out page.
Connected systems
Video, access control, intrusion, perimeter detection, ANPR, fire, intercom, guard tours and BMS.
Ergonomics and 24/7 operation
A room used day and night is designed for human vigilance. ISO 11064 provides the framework: viewing distances and angles to the wall, glare-free indirect lighting, treated acoustics, stable temperature, clear circulation and a rest area nearby. Alarms are prioritised to avoid fatigue: too many unqualified alerts and operators end up ignoring them.
Resilience and cybersecurity
- backed-up power (UPS, generator) and redundant cooling;
- redundant servers and, for critical sites, a fallback room;
- security network separated from office IT, named accounts and role-based rights;
- logging of operator actions and controlled equipment updates.
Use cases in Tunisia
- Banks and insurers: centralised supervision of branch networks, video verification and out-of-hours alarms.
- Industry and free zones: large perimeters, truck flows, hazardous sites and shift teams.
- Energy, ports and airports: critical infrastructure, multi-party coordination.
- Headquarters and campuses: access, visitors, fire and BMS run from one room.
Mistakes to avoid
- buying a large video wall before defining incident scenarios;
- connecting every system without priority rules: the operator drowns;
- choosing equipment without open interfaces that cannot be integrated later;
- neglecting training and procedure updates after handover;
- putting servers in the operator room.
Checklist before starting
- existing systems, brands and versions;
- number of sites to supervise and their network links;
- main incident scenarios and current procedures;
- operators per shift and operating hours;
- available space, power and cooling constraints.
