About Sebastien

I support companies, integrators, and technical managers who wish to validate, challenge, or secure an electronic security project.

I mainly work on topics related to video surveillance, access control, intrusion detection, and the technical architecture of systems.

I can help you with:

• Technical audit of a quote or a project
• Validation or counter-expertise of a security solution
• Remote technical assistance for a specific need or an ongoing project

My approach is technical, pragmatic, and field-oriented, with a simple goal: to help you make the right decisions, avoid design errors, and validate your choices before deployment.

If you have a project to frame, a quote to challenge, or need a quick expert opinion, I can intervene effectively remotely.
