Whether you're protecting a shop in the Vieux-Port, securing a nursing home in Aix-en-Provence, or monitoring a warehouse near Fos-sur-Mer, installing a commercial CCTV system in France comes with specific legal obligations that differ significantly from other countries. This guide covers what you need to know before, during, and after installation — from French CNIL compliance to choosing between Hikvision, Dahua, and Axis.

1. French Legal Requirements: What You Must Know

Vidéoprotection vs Vidéosurveillance — The Legal Distinction

Vidéoprotection covers cameras in areas open to the public (reception halls, visitor parking, building entrances): this requires a prefectoral authorization (autorisation préfectorale). Vidéosurveillance covers private areas (offices, warehouses, storage rooms): this falls under GDPR and the French CNIL. Most businesses need to comply with both regimes.

7 Mandatory Compliance Steps

• File an authorization request with the local préfecture for any public-facing cameras
• Register the system in your company's GDPR data processing register (registre des traitements)
• Conduct a DPIA (Data Protection Impact Assessment / AIPD) if high risk is identified
• Inform employees through visible signage and inclusion in the company's internal regulations (règlement intérieur)
• Consult the CSE (employee representative body) before installation
• Limit footage retention to 30 days maximum (unless required by a court order)
• Never film break rooms, changing rooms, restrooms, or fixed workstations

Special Case: Nursing Homes (EHPADs)

The CNIL's February 2024 recommendation is very strict: in-room cameras are only permitted in cases of substantiated suspicion of mistreatment, after all alternative measures have failed (nurse call buttons, internal investigation procedures). In-room surveillance is never allowed for "comfort" or "service improvement" — even with the resident's consent. Common areas (lobby, corridors, parking) can be covered under standard compliance rules.

2. Camera Brand Comparison 2026

Three manufacturers dominate the professional French market. Hikvision holds approximately 20-23% of the global market, Axis around 19.6%, and Dahua approximately 10-17% depending on the segment.

3. System Sizing by Business Type

Retail Shop (4-8 cameras)

Cover entrance, cash register, stockroom, and exterior. Typical setup: 4-8 indoor dome cameras + 1-2 outdoor bullet cameras, 8/16-channel NVR, mobile app access. Budget: €2,500 to €6,000 excl. VAT installed.

Nursing Home / EHPAD (8-32 cameras)

Cover all access points, corridors, common areas, parking, and perimeter. Perimeter detection with line-crossing is critical for Alzheimer facilities (wandering prevention). Budget: €8,000 to €25,000 excl. VAT depending on size.

Hotel / Restaurant (4-16 cameras)

Discretion is key — flush-mount dome cameras and mini-domes are preferred. Integration with access control (badge/card) is common. Budget: €4,000 to €15,000 excl. VAT.

Warehouse / Industrial Site (16-64+ cameras)

Large areas, dust, vibrations, variable lighting. IP67-rated cameras, thermal detection, and perimeter analytics recommended. Storage must be sized for 30 days at 30 fps in HD. Budget: €15,000 to €50,000+ excl. VAT.

Co-owned Building / Syndic (4-12 cameras)

Lobby, parking, secondary access, waste/bike storage areas. Financing typically approved by co-owner vote (majorité article 25). Annual maintenance contract is essential. Budget: €3,000 to €10,000 excl. VAT.

4. Common Mistakes to Avoid

Mistake #1: Undersized storage. A 2TB NVR for 16 cameras at 4MP won't last 30 days. Allow approximately 1TB per 4MP camera for 30 days of continuous recording, or 300GB in motion-detection mode.

Mistake #2: Ignoring lighting. Even the best camera gives unusable footage in a dark parking lot. ColorVu/Full-Color cameras help, but proper LED lighting remains the cheapest and most effective complement.

Mistake #3: Skipping maintenance. An unmaintained system degrades within 2 years: outdated firmware, failing hard drives, misaligned cameras. A maintenance contract with a guaranteed intervention SLA (4h for healthcare, 24h for retail) is essential.

Mistake #4: DIY installation. Consumer "plug and play" kits are not designed for business environments. Default passwords, open ports, no network segmentation — these create serious cybersecurity vulnerabilities. A professional installer configures dedicated VLANs, encryption, and secure remote access.

5. How to Choose an Installer in Southern France

• Verify their CNAPS accreditation (mandatory for any private security activity in France, including CCTV installation)
• Ask for manufacturer certifications (Hikvision, Dahua, or Axis partner status)
• Request references in your industry (healthcare, retail, hospitality, industrial)
• Check the maintenance SLA: guaranteed response time, support hours, hardware replacement
• Prefer a multi-service integrator (telecom + CCTV + alarm) to avoid juggling multiple contractors
• Ask if the installer handles the préfecture and CNIL paperwork on your behalf
• Prioritize local presence: a PACA-based installer can respond within hours
