Glossary
Every analytics, security and operations term ITOI uses, defined in plain English.
Access Control
Any system used to manage who can enter a physical space and when, ranging from simple keycards and PIN pads to biometric methods like facial recognition. Modern access control is often integrated with broader security systems, so an access event — a door opening — can be automatically cross-checked against camera footage or an alarm state.
ANPR (Automatic Number Plate Recognition)
Technology that automatically reads and logs vehicle number plates, typically using camera-based image recognition. It's commonly used for car park management, controlling entry and exit at a gated site, or flagging a specific vehicle of interest against a watchlist.
ATV (Average Transaction Value)
The average dollar amount spent per transaction, calculated as total revenue divided by number of transactions. A rising ATV alongside a falling conversion rate can indicate a shift toward fewer, higher-value purchases rather than genuine growth.
AUR (Average Unit Retail)
The average selling price per individual item sold, calculated as total revenue divided by total units sold. It's distinct from ATV, which measures value per transaction rather than per item — a rising AUR alongside a flat ATV usually means fewer, pricier items are going into each basket.
Autonomous Patrol
The use of a self-navigating robot to physically patrol a site on a schedule or continuously, using onboard sensors and cameras to detect anomalies without a person needing to walk the route. Unlike a fixed camera, an autonomous patrol unit can cover a large or irregular site with consistent, repeatable coverage.
Benchmark Percentile
A way of expressing a single site's performance relative to a comparison group, showing what percentage of other sites it's performing better than. Being in the 75th percentile for conversion rate, for example, means the site converts better than 75% of the sites it's being compared against — it's a relative measure, not an absolute target.
Capture Rate
The percentage of people passing by a store who actually walk in, calculated as store traffic divided by passerby traffic outside. It isolates how effective a storefront, window display or entrance is at converting passersby into visitors, before any in-store factors come into play.
Cash Refund Risk
A loss-prevention indicator that flags cash refunds carrying a higher likelihood of being fraudulent or improperly processed — for example, a refund with no matching original sale, or one processed well outside normal trading hours. It's used to prioritise which refunds get a closer manual review, rather than treating every refund as equally low-risk.
Conversion Rate
The percentage of visitors who make a purchase, calculated as transactions divided by visitors. It's one of the clearest signals of how well a store's floor experience, staffing and checkout process are working.
Dwell Time
The length of time a visitor spends within a store, venue or specific zone before leaving. Longer dwell time in an area often correlates with higher engagement, though it can also indicate friction — a long checkout queue, for instance — so it's usually read alongside other metrics rather than on its own.
Facial Recognition Accuracy
A measure of how reliably a facial recognition system correctly matches a face to the right identity, usually benchmarked against standardised datasets such as LFW (Labeled Faces in the Wild). Accuracy is typically reported alongside a system's speed and its false non-match rate, since a fast system that frequently misidentifies people isn't a useful one.
False Positive / False Negative
A false positive is when a system incorrectly flags something as a match or a threat — for example, identifying the wrong person as a match. A false negative is the opposite: failing to flag something that genuinely was a match or a threat. Both are used to evaluate detection and recognition systems, and there's usually a trade-off between minimising one and minimising the other.
Footfall
Another term for foot traffic xe2x80x94 the number of people entering a physical space over a given period. It's most commonly used in the UK/AU retail and shopping-centre context, and is largely interchangeable with "traffic."
Line Item Void
The removal of a single item from a transaction before it's finalised, without cancelling the whole sale. A high rate of line item voids at a particular register or by a particular staff member is often flagged for review, since it can indicate anything from a genuine change of mind to a deliberate attempt to under-ring a sale.
Loss Prevention
The set of practices, systems and technology used to reduce theft, fraud and inventory shrinkage within a retail or venue environment. Modern loss prevention increasingly relies on the same camera and sensor infrastructure used for retail analytics, flagging unusual behaviour patterns in real time rather than relying solely on after-the-fact stocktake discrepancies.
Perimeter Security
Security measures focused specifically on the outer boundary of a property or site — fencing, gates, perimeter cameras and motion sensors — designed to detect or deter unauthorised entry before it reaches the building or asset itself. It's typically the first layer in a broader, multi-layered security approach.
Post Void
A transaction that is voided (cancelled) after it has already been completed and the till drawer has opened, rather than before the sale is finalised. Because the drawer has already opened, post voids are a commonly monitored indicator in loss-prevention programs, since they can — though don't always — signal a cash-handling issue.
Shopper Yield
A combined measure of conversion rate and average transaction value, expressed as revenue generated per visitor. Because it blends two metrics, it can't be improved by boosting one at the expense of the other, making it a reliable indicator of genuine performance.
Traffic
The total count of people entering a store or venue over a given period, usually broken down by hour and day. It's the base measurement almost every other retail metric is calculated from, so its accuracy affects everything derived from it.
UPT (Units Per Transaction)
The average number of individual items included in each transaction, calculated as total units sold divided by number of transactions. It's a direct indicator of how effectively upselling, bundling and cross-merchandising are working on the floor.
Zone Analytics
The practice of measuring foot traffic, dwell time and movement within specific defined areas of a store or venue, rather than as a single sitewide total. It's what turns a raw traffic count into an actionable read on which parts of a space are working and which are being skipped.
