Video surveillance — see, understand, protect
A good video installation isn't the camera brand. It's the site study, cabling, recorder, lighting and legal compliance.
— Partenariats & certifications
Certifications video surveillance.
— Video surveillance in numbers
Three figures to frame ROI and compliance.
1 month
Image retention period recommended by the French CNIL for standard use: a period “not exceeding one month”. GDPR framework documented at installation.
CNIL — video surveillance at work-80%
Shrinkage observed 12 months after a pro install (video + alarm coupled + monitoring) in retail.
BISPRO observation
100%
CNIL compliance: prefecture declaration, signage, GDPR processing register, works council notification — delivered with every project.
01 · STUDY
Site study & sizing
A serious site study weighs more than the sensor brand. That's where 80% of blind spots are avoided.
Site visit
Risk analysis, layout plan, architectural constraints.
Sensor selection
Resolution, focal length, IR, IK / IP ratings, WDR, low light.
Bandwidth & storage
Flow and legal retention calculation.
Legal compliance
GDPR, French Internal Security Code, prefecture declaration.
02 · BRANDS
Brands deployed
Three ecosystems mastered. Contextual recommendation, never vendor-driven.
Hanwha Wisenet
Premium image, on-board analytics, robustness — high-mid market reference.
Hikvision
Value, broad range, low-light ColorVu, AcuSense.
Axis Communications
High-end reference, open platform, product longevity, Zipstream.
03 · NVR & VMS
NVR, storage & supervision
Sensors capture. NVR retains. VMS exploits. Each sized correctly.
Dedicated NVR
Sized by number of streams, codecs and retention.
Redundant storage
Suitable RAID (1 / 5 / 6 / 10), legal duration respected (30 days default).
Centralised VMS
Wisenet WAVE, Axis Camera Station, HikCentral depending on ecosystem.
Secure remote access
VPN, MFA, named accounts, access logging.
04 · ANALYTICS
Video analytics
On-board analytics turn passive video into an operational decision tool.
Intrusion detection
Line crossing, abandoned object, camera tampering.
Counting & heatmap
People flow, hot zones, dwell time.
LPR — plates
Licence plate recognition for car parks and vehicle access.
Alarm verification
Automatic visual verification on intrusion trigger.
05 · COMPLIANCE
Legal compliance
Compliance isn't optional. A non-compliant install exposes the company, not just the installer.
Prefecture declaration
Mandatory whenever a publicly accessible place is filmed (France).
CNIL information
Signage, processing register, internal regulations notice.
Retention period
30 days default, up to 1 month without derogation, adjusted by purpose.
