Technical specifications - 3D video sensor

Presentation

The video sensor is a counting system using the 3D video technology.
It is placed above the access, fixed to the ceiling and counts every person located in the counting area below.

The 3D video sensor is a very precise counting system, even for wide or busy accesses.

Technical specifications

Technology	Counting method: distance from the ground is determined with 3D technology
Counting area size	Proportional to the sensor's height. The higher the sensor, the wider the area covered. For example, a sensor fixed at a 6 meters height can cover an area of a 9 meters width.
Power type	PoE (Power over Ethernet) wiring required for power and data communication (a PoE injector* can be used)
Counting data retrieval	Ethernet (Ethernet / Wifi relay possible)
Counting data refresh	Every 3 seconds
Dimensions	130 x 94 x 30 mm
Positioning	Mounting height between 2.20 and 20 meters Inclination: +/- 15°
Accuracy	99%
Mounting	Bolted down to the ceiling
Internal memory	120 days of hourly data
Colour	White
Customisation	Customisable colours

*A PoE (Power over Ethernet) injector plugs into an electrical outlet and adds power to a simple network cable, transferring both power and data to a device.

Setup

Prerequisites

• • Mounting area must be clearly defined (ceiling height starting from 2.20 to 20 meters)
  • The designated area may be drilled for mounting purposes
  • Available PoE wiring nearby for power and network
  • The higher the sensor, the wider the area covered: hence the sensor's height shall be proportional to the desired counting area
  • A subnet with DHCP (or provide : Fixed IP address, Subnet Mask, Default Gateway, DNS)

Surface-mounted installation

On-site installation

• • Video sensor will be bolt down, wired and calibrated
  • Data retrieval assessment

Post-installation monitoring

• • Checking data consistency and validating correction coefficients
  • Sensor ready

Network architecture

Some prerequisites are necessary to calibrate the sensor and collect the data : 
- An internet access through ports 80/HTTP, 123/NTP, 443/HTTPS.
- A DHCP server or a static IP address.

Regarding GDPR regulation

Affluences sensors are not affected by GDPR regulation since frame analysis is processed localy. We only collect anonymized counting data, such as 15 entries at 11am for example.

The 3D video sensors implemented by Affluences are not subject to CNIL or RGPD regulations.

The logical analysis and counting device is directly embedded in the counter, and the captured data flows are exploited on the fly and locally.

The only data stored and sent to the Affluences servers and databases are encrypted numerical count data (e.g. 15 entries at 11:05).
