As the day comes to a close: the final patrol by our mobile surveillance team
When the last employees leave the building and the lights slowly dim, Rachid’s most important shift of the day begins. The industrial park is quiet, but for him, this is when things get busiest. Whereas in the morning he opens the buildings to ensure a safe start to the day, now his focus is on locking up, conducting inspections, and preventing risks such as fire, burglary, or technical malfunctions. As soon as the gate closes, the responsibility for safety rests entirely in his hands.
In the first part of this series, we followed Rachid during his opening round, the start of a new workday. Now, at the other end of the day, the focus is on the final round: the moment when calm returns, but alertness is at its peak.
The final lap, the start of a good night's sleep
For Rachid, the final patrol and lock-up round is more than just a routine task. It’s the round that wraps everything up and, at the same time, sets the stage for a good night’s sleep for our client. He parks his patrol car near an abandoned building and checks his flashlight, device, and instructions before he begins. His attention is fully focused on the details, because it’s precisely at the end of the day that the greatest risks lie in the smallest things.
First comes the fire safety inspection: fire alarms, emergency lighting, and escape routes are carefully checked. No boxes blocking escape routes, no live electrical equipment, no trash bins near emergency exits? These seemingly small actions prevent major incidents. Next comes the closing inspection: doors, gates, windows, and fencing. Everything is physically checked, not just visually.
Once Rachid is certain that everything has been properly secured, he activates the alarm system and locks the premises completely in accordance with the client’s instructions. Only then is his work done, and the rest of the organization can also settle in for the night with peace of mind.
Technology enhances craftsmanship
Mobile surveillance is no longer just a matter of walking around and observing. Modern technology helps ensure that every area is actually visited. NFC tags are located throughout the grounds and often inside the building as well. These are small electronic tags that can exchange information with a mobile device via Near Field Communication. As soon as Rachid briefly holds his device up to one, it automatically registers that he has been at that location.
Each scan records the time and exact location during the security patrol and sends that data directly to the control room. This creates an accurate digital log of the patrol. As a result, the client can always verify that the patrol was completed in full and on time. This not only increases transparency but also builds trust in the service.
Still, technology remains merely a tool. An NFC tag confirms that Rachid has been somewhere; his experience and observation skills determine what he sees there. A trash can that’s been moved near an emergency exit, the smell of smoke, or water stains near an electrical panel? That’s still a job for people.
More than just monitoring: contributing ideas and making improvements
During his final inspection, Rachid looks beyond the checklist. He pays attention not only to what’s wrong, but also to what could be improved. A broken light bulb by the side entrance, an obstacle in the emergency exit, or a gate that’s hard to close—he spots it and reports it immediately to the client. Small details, but ones that are crucial to daily safety.
Our security guards serve as an organization’s extra set of eyes. They are on duty when others are not and notice issues that would otherwise go unnoticed: a window left open, a poorly lit corner, or a lock in need of maintenance. These observations form the basis for structural improvements.
At SERIS, thinking proactively is part of the job. We don’t just conduct inspections; we actively contribute to a safer work environment. Small changes—such as better lighting, maintenance, or a more efficient route—make the difference between routine and real progress over time.
Real-time reporting
Every finding is recorded immediately. Using his device, Rachid sends photos, the location, and a description to the control room and the client. This provides an up-to-date overview of what was checked, noted, and addressed during the round. No paper logs or reports after the fact—just immediate and transparent communication.
When action is required, the control room immediately contacts the appropriate party—whether that’s a glazier, technical support, or the police. Issues are not only logged but also addressed immediately. This prevents delays, minimizes damage, and keeps the client fully informed at all times, even in the middle of the night.
Each report also provides valuable information for trend analysis. By identifying patterns such as recurring malfunctions, vulnerable areas, or common incidents, SERIS offers targeted recommendations for preventive measures. In this way, security is gradually enhanced.
Closing procedures: safety for everyone
Sometimes Rachid still comes across employees who are working overtime or unloading the last truck. At such times, SERIS provides an escort service. This is a service in which a security guard safely escorts employees to their vehicle or the exit of the premises.
That’s not a luxury, but a deliberate safety measure. An empty parking lot or a dark corner can feel unsafe, especially when someone is going out alone or carrying valuables. The presence of a security guard helps prevent risks and gives employees the confidence that they can leave safely.
Lock-up supervision thus fits seamlessly with the core of our mobile surveillance: ensuring safety, even outside of working hours.
Continuity starts with attention
Every location has its own dynamics, layout, and risks. That is why SERIS provides instructions that are precisely tailored to the client’s specific needs and procedures. Whether it’s a logistics site, an office building, or a manufacturing facility, every security guard knows exactly what is expected of them.
In the Rotterdam-Drechtsteden region, a dedicated team of more than twenty security guards is on duty around the clock. They know their area like the back of their hand. That knowledge of routes, routines, and risks is what makes the difference between reacting and thinking ahead.
Local ties are key to continuity. If a colleague is unable to work or runs late, another team member can seamlessly take over the shift. Keys, alarm codes, and instructions are carefully documented to ensure that every shift proceeds as planned. For the client, this means peace of mind: security operations continue without interruption, regardless of the circumstances.
Always stay alert, even when the lights go out
When Rachid leaves the premises and night falls, everything seems quiet. Yet beneath that calm lies a constant state of readiness. Should an alarm go off, a suspicious situation arise, or a technical malfunction occur, SERIS is immediately on standby.
In the next installment of this series, we’ll take you through the next step: the response to an alarm. We’ll show you how reports are handled, how security guards and the control room work together, and how we ensure that security never stops—even in the middle of the night.
