Sentinel mobile surveillance unit on a construction site – self-contained site surveillance by AEGIS Protect

Self-contained security. Exactly where it is needed.

Sentinel watches construction sites, open areas and critical zones – even without an existing power or internet connection.

  • ready to use quickly
  • self-contained and flexible
  • professional alarm handling

Sentinel is AEGIS Protect’s mobile security solution for self-contained construction-site surveillance, perimeter surveillance and temporary outdoor surveillance. Suitable without a mains connection and without a fixed internet line, with monitoring by the alarm receiving centre and intervention from a single source.

When conventional security reaches its limits

Many outdoor areas are hard to protect economically with permanently wired CCTV or standing guards – especially where infrastructure is missing or the site keeps changing.

  • Large or remote areas without overview
  • No mains connection or no fixed internet line
  • Changing construction sections and moving risks
  • Theft, vandalism and unauthorised entry
  • High cost of standing guards
  • Difficult tracing and documentation of events

Sentinel

A security solution, fully self-contained as a stand-alone system

Sentinel protects sites, construction areas and critical zones even where no conventional security infrastructure exists. The mobile security solution is as suitable for temporary outdoor surveillance as for long-term projects.

When construction fields or project sections change, the units can be relocated and adapted to the new risk – without a new cable route and without months of planning.

Not just placing technology, but creating a working security chain.

Advantages at a glance

Clear security for outdoor areas – from rapid deployment to alarm handling in the control centre.

Self-contained operation

Protection even without an existing mains connection. Ideal for remote and temporary sites.

Rapid deployment

Ready at short notice after areas have been agreed. Less lead time than permanently wired technology.

Flexible positioning

Units can be moved when construction sections or risks change.

Early detection

Unauthorised people and vehicles are detected early – before damage occurs.

Visual alarm verification

Events reach the control centre with image context. That helps reduce false alarms.

Professional alarm handling

Our ARC checks alarms and initiates measures according to your alarm plan.

Scalable surveillance

From individual sections to large sites – modular and expandable.

Suitable for long-term projects

Temporary or over years: support and adaptation across the full project duration.

How the security chain works

From analysis to intervention – clearly defined and matched to your site.

  1. 1

    Analyse the surveillance area

    We assess risk, access, network coverage and the legal framework.

  2. 2

    Position Sentinel systems

    Setup at the critical points – flexibly and without an expensive cable route.

  3. 3

    Detect events automatically

    Relevant movement is detected and transmitted on an event basis with image context.

  4. 4

    Have the alarm checked by the control centre

    The ARC assesses the incident and decides according to your escalation matrix.

  5. 5

    Initiate measures

    Live challenge, notification of contacts, intervention or – where the situation warrants – the authorities.

Use cases

Where mobile site surveillance and temporary outdoor surveillance are particularly useful.

Security for critical and long-term projects

Operators of critical infrastructure and major construction projects need increased protection, clear documentation and reliable escalation – often at remote sites and across multi-year construction phases.

Sentinel can form part of an individual protection concept. We do not claim that the solution automatically meets all statutory KRITIS requirements – we match technology, alarm plan and intervention to your risk.

KRITIS umbrella act & physical protection
  • Increased requirements for protection and documentation
  • Often remote sites without fixed infrastructure
  • Large or changing project areas
  • Multi-year construction phases with adaptation to progress
  • Agreed alarm and escalation processes

Technology and guarding complement each other

Sentinel does not replace security officers – it detects events early, while the control centre and intervention handle the response.

Frequently asked questions

Short and clear on self-contained construction-site surveillance, control-centre monitoring and the use of Sentinel.

Does Sentinel work without a mains connection?
Yes. Sentinel is designed for self-contained operation and can protect sites where there is no permanent mains connection. We match the specific energy supply to your project in a site check.
Is an internet line required?
No. The systems normally use mobile data transmission. The prerequisite is adequate network coverage at the site – we check this before go-live.
How quickly can the solution be set up?
After surveillance areas and the alarm plan have been agreed, Sentinel is typically ready at short notice. Setup and commissioning depend on site size, logistics and the desired start date.
Can the system be relocated during a project?
Yes. When construction sections or risk situations change, the units can be moved and repositioned – without permanently wired infrastructure.
What happens in an alarm?
Events are passed with image context to our alarm receiving centre (ARC) and checked there. The measures agreed with you then follow – for example a live challenge, notification of contacts or calling an intervention service. Police or fire services are only notified where the situation warrants it and according to your alarm plan.
Can several areas be watched at the same time?
Yes. Sentinel can be expanded modularly – from individual sections to larger sites with several monitoring points and a single alarm logic.
Is Sentinel also suitable for long-term projects?
Yes. Besides temporary deployments, the solution is suitable for multi-year construction phases and long-term outdoor surveillance. Duration, adaptation and removal are planned from the outset.
Can the solution be monitored by a control centre?
Yes. Connection to our ARC is part of the concept. We agree technology, availability, alarm texts and escalation with you before go-live. Further background: video monitoring.
Is a combination with an intervention service possible?
Yes. Technology and guarding complement each other: Sentinel detects events early, the control centre assesses them, and intervention officers handle the on-site response if needed.
Which types of site is the solution suitable for?
It is particularly suitable for construction sites, solar parks, energy facilities, substations, logistics and industrial areas, vacant buildings, infrastructure projects and remote outdoor sites – wherever conventional cabling would be uneconomic or too slow.
How does it differ from a mobile camera tower?
Self-contained Sentinel units are often quicker to deploy on areas without a tower foundation and suit perimeters and changing sections. Camera towers typically provide more height and overview. Both can be monitored with the same ARC logic.
