Sentinel
Transform any shelf gondola into a real-time inventory intelligence and loss prevention system.
Sentinel is a modular shelf intelligence system that uses WeightAI™ technology to monitor every product movement, prevent unauthorised removal, and deliver behavioural analytics. 4 IoT load sensors sit at the base of the gondola, not under every shelf. A single Sentinel unit monitors every shelf above it in real-time, making it a fraction of the cost of per-shelf sensor systems, with no modifications to the shelving or fixture required.
Benefits
Sentinel monitors every product movement across the entire gondola in real-time. Unauthorised removal attempts are detected instantly based on retailer-defined rules. A complete audit trail is created automatically for every shelf interaction and security investigation.
Sentinel retrofits any gondola into a smart inventory system without replacing fixtures or incurring infrastructure costs. Inventory is tracked automatically across all shelves, no manual scanning or counts. Slow-moving vs. high-velocity products are identified for category optimisation.
Sentinel deploys in minutes on existing fixtures with no structural modifications. Simple planogram setup means product changes require no recalibration. Real-time stock level monitoring begins immediately, eliminating manual count cycles from day one.
Sentinel monitors stock levels across all gondola shelves continuously. Providing real time stocking state allowing operators notify staff before stock runs out eliminating out-of-stock situations without any manual scanning or counting.
Sentinel captures customer interaction patterns and shopping behaviour across every shelf on the gondola. Operators gain peak traffic times by product and category, shelf performance analytics, and optimisation insights all via a remote cloud-based management platform.
Sentinel works alongside existing security and surveillance systems. Security personnel receive instant alerts on unauthorised removal attempts. Every shelf interaction is logged, creating a complete audit trail for investigations, with no cameras or RFID required.
How it works
Install. Monitor. Protect.
Four IoT load sensors at the gondola base deliver real-time intelligence across every shelf from the moment Sentinel is activated.
FEATURES
Four IoT load sensors install at the base of any standard gondola or fixture, no per-shelf hardware, no structural modifications to shelving or facility. Compatible across ambient shelving, and specialty fixtures. Operational within minutes of WeightAI™ sensor activation.
From the gondola base, Sentinel tracks all product additions and removals across every shelf in real-time. Each product is recognised by its unique weight signature with 99.8% accuracy. Unauthorised removal attempts are detected instantly based on predefined security rules. Product changes require no recalibration.
Security personnel receive instant notification of any unauthorised product removal. Sentinel tracks patterns of suspicious activity across multiple shelf interactions, integrates with existing security and surveillance systems, and creates a complete audit trail for all shelf interactions and investigations.
Real-time stock level monitoring across all gondola shelves, no manual counts or scanning. Slow-moving vs. high-velocity products are identified for merchandising optimisation. Continuous accuracy from WeightAI™ prevents inventory shrinkage from counting errors.
Customer interaction patterns and shopping behaviour tracked across the full gondola. Peak traffic times by product and category, shelf performance analytics, and optimisation insights — all accessible via remote cloud-based platform with no staff on site required.
Frequently Asked Questions
Sentinel is a modular shelf intelligence system that transforms any standard retail gondola into a real-time monitoring and inventory management platform. Using SHEKEL’s WeightAI™ technology, it tracks every product movement, detects unauthorised removal, and delivers behavioural analytics without replacing existing fixtures or installing complex camera systems.
Sentinel uses four IoT load sensors installed at the base of the gondola, not under every shelf. A single unit monitors every shelf on the entire gondola from one position. This makes Sentinel significantly cheaper to deploy than per-shelf systems, with no modifications to the shelving or facility required.
No cameras. No RFID. Sentinel uses WeightAI™ weight sensing technology exclusively. Every product is identified by its unique weight signature, no tagging, no scanning, and no privacy concerns associated with camera-based systems.
Sentinel is compatible with any standard gondola or shelving fixture. No structural modifications to the shelving or facility are required, making it suitable for any retail format.
Sentinel is operational within minutes of WeightAI™ sensor activation. Four IoT load sensors nstall at the base of the gondola with no structural modifications to shelving or facility. There is no complex calibration, the system begins monitoring immediately after installation.
No. Sentinel retrofits directly onto any existing gondola without replacing fixtures or incurring infrastructure costs. This makes it one of the lowest-cost paths to real-time shelf intelligence available to retailers today.
Sentinel’s simple planogram configuration enables easy product changes without recalibration. New products can be added and planograms updated remotely via the cloud-based management platform, no technician visit or on-site staff required.
Sentinel detects unauthorised product removal instantly, based on retailer-defined security rules. Security personnel receive real-time alerts the moment a removal attempt is identified. Sentinel also tracks patterns of suspicious activity across multiple shelf interactions and integrates with existing security and surveillance systems.
Yes. Every shelf interaction is logged automatically, creating a complete audit trail for all product movements, removal attempts, and security incidents. This gives retailers the documentation needed to support loss prevention investigations.
Retailers achieve measurable loss prevention ROI within months of deployment. By monitoring every product movement in real-time and alerting on unauthorised removal instantly, Sentinel transforms passive shelves into active revenue protection systems, without the cost of replacing fixtures or installing cameras.
WeightAI™ recognises every product by its unique weight signature with 99.8% accuracy. Every addition and removal across all shelves on the gondola is tracked in real-time, eliminating counting errors and providing always-accurate stock levels without manual intervention.
Yes. Sentinel monitors stock levels continuously across every shelf on the gondola. Predictive restocking alerts notify operators before stock runs out — eliminating out-of-stock situations without any manual scanning or counting.
Yes. Sentinel’s real-time tracking identifies slow-moving vs. high-velocity products across every shelf category. This gives buyers and merchandisers the data to optimise ranging, placement, and replenishment decisions, directly from the shelf, with no manual data collection.
Yes. All shelf monitoring, inventory data, loss prevention alerts, and analytics are accessible via a remote cloud-based platform. Planograms and product configurations can be updated remotely, no staff on site required.
Yes. Sentinel integrates with existing security and surveillance systems and feeds real-time data into retail management platforms. Every transaction, removal event, and stock movement is logged and reportable — giving operators a single view of shelf performance across their estate.
