Video surveillance

Video surveillance makes it possible to monitor, deter, and secure sensitive areas on a site.

It helps protect buildings, property, and people by helping to prevent malicious acts, detect unusual situations, or document an event. It can operate on its own or be integrated with other security solutions, such as access control, intrusion detection, intercom systems, or monitoring systems.

How does video surveillance work?

Video surveillance relies on a network of cameras installed in designated areas. Images can be viewed live, recorded, or stored for review in the event of an incident.

Depending on the site’s needs, the system can be supplemented with advanced features such as motion detection, image analysis, license plate recognition, night surveillance, or video verification.

The goal is not simply to install cameras, but to place the right equipment in the right locations, with image quality, storage capacity, and access policies tailored to the site’s operations.

What is the purpose of video surveillance?

Video surveillance addresses several security needs.

It allows you to monitor sensitive areas, deter certain malicious acts, verify an alert remotely, or help determine what happened after an incident.

It can be used to supplement human presence, reinforce an access control system, monitor a parking lot, protect a storage area, track delivery flows, or secure technical facilities.

Within a more comprehensive system architecture, video can be integrated with intrusion detection, access control, or monitoring to help teams respond more effectively.

Video surveillance or video security: what's the difference?

Both terms refer to similar devices. The difference depends mainly on the installation location.

Video surveillance generally applies to private premises: offices, warehouses, storage areas, private parking lots, commercial buildings, or internal areas.

Video security is typically used in public places or areas open to the public: streets, train stations, shopping districts, facilities open to the public, or areas accessible to visitors.

In both cases, the measure must serve a specific purpose, be proportionate, and comply with the applicable rules regarding the provision of information to individuals and data protection.

Video surveillance tailored to each sensitive area

Video surveillance serves a different purpose depending on whether it protects an entrance, a car park, a stockroom, a loading bay or a plant room. This table helps you quickly identify the areas to monitor and the most suitable video solutions.

Space to monitor Main requirement Possible solution
Main entrance Thoroughfare for staff, visitors and contractors Monitor movement and make alarm verification easier Fixed camera, supervision, linked to access control
Parking Vehicle access, parking and outdoor traffic Monitor vehicles and secure access points Outdoor camera, night vision, number plate recognition
Stockroom or warehouse Area exposed to theft, loss or unauthorised access Deter intrusions and document incidents Indoor camera, motion detection, recording
Loading bay Interface between hauliers, goods and internal teams Track movements and analyse incidents Flow-oriented cameras, recording, video supervision
Plant room Sensitive space linked to building operation Monitor a critical area and reduce blind spots Targeted camera, restricted access, video alarm verification
Industrial or outdoor site Large areas, weather or environmental constraints Watch high-risk areas and detect abnormal situations Outdoor cameras, infrared, thermal as required
