¶ 🏗️ Darwin System Infrastructure
Updated — March/2026
This document defines the Darwin infrastructure standard, including physical positioning, installation, and operational best practices.
These guidelines must be applied across all phases:
- design
- construction
- installation
- fine-tuning
- validation
¶ 🎯 Standardization Objective
The Darwin standard ensures:
- reliable visual recording of operations
- accurate detection of No Scan (unregistered movement)
- consistency across stores
- easier maintenance and scalability
⚠️ Installations outside this standard directly compromise system effectiveness.
¶ 📷 Camera Positioning (POS)
Camera positioning is critical for system operation.
The camera must capture, within the same frame:
- scanner
- scale
- product and cart flow
👉 Missing any of these elements compromises analysis.
¶ 🎯 Field of View (FOV)
- Recommended angle: ~112°
Ensures:
- full POS coverage
- no image cropping
- adaptability to different layouts
📌 Practical rule:
- Low FOV → loss of information
- Proper FOV → full operational coverage
⚠️ Lenses below the recommended specification may prevent proper system operation.
¶ 📐 Camera Alignment
- Angle: 90° (perpendicular to the counter)
- Centered on:
- scanner
- scale
Benefits:
- eliminates blind spots
- improves analysis accuracy
- maintains visual standardization
¶ 📏 Installation Height
- Recommended height: ~2.5 m
Ensures:
- optimal framing
- image stability
- better motion tracking
¶ 🛒 Traditional Checkout
- camera centered
- full POS visibility
- axis alignment
- FOV ≈ 112°
- 90° angle
- full coverage area
- no obstructions
- minimum aisle width: 90 cm
¶ ✅ Mandatory Rules
- camera centered on POS
- no lateral offset
- continuous capture of:
- scanner
- scale
- cart flow
¶ 🤖 Self-Checkout
Follows the same principles as traditional checkout, with attention to:
- customer height variation
- absence of a fixed operator
⚠️ Camera must remain aligned with scanner and scale.
¶ 🎧 Audio Capture
Two available models:
¶ 🔹 Camera Audio
- built-in microphone
- simplified installation
- reduced cabling requirements
¶ 🔹 External Microphone
- greater capture control
- improved audio quality
📍 Positioning:
- ~10 cm from the counter edge
- operator side
- aligned with the scanner
📌 Infrastructure:
- 1x0.2 mm² cable
- dedicated power point
¶ 🧱 Infrastructure – Cabling
¶ 🔹 Floor Routing
- embedded conduits
- separation of power and data
- structured cabling standard
¶ 🔹 Ceiling Routing
- easier maintenance
- simplified expansion
- rack-based organization
¶ 🔹 Low Ceiling Environments
- compact environments
- structural limitations
- requires adaptation
¶ 🛡️ EasiGuard Infrastructure
- overhead or underground routing
- correct antenna positioning
¶ 📡 RF Infrastructure
- mandatory alignment
- minimum spacing required
- avoid metallic interference
¶ 📶 Web Enable Infrastructure
- communication between POS and devices
- system integration
¶ 🔌 Integration (Camera + Audio + Power)
- integration of video, audio, and power
- electrical and logical separation required
¶ 💡 Summary
The Darwin standard ensures:
- accurate video analysis
- operational reliability
- consistency across stores
- solid foundation for auditing and loss prevention
👉 Proper infrastructure = correct system operation
