Glossary of Terms

  • Access Control

    Access control – refers to a system that allows secure entry to specific areas and resources in a given physical facility or computer-based information system.

  • Accuracy

    Accuracy– used within the field of people counting to describe both how well a people counting device picks up and counts targets under different environmental conditions and varying volumes of pedestrian traffic, and how well bi-directional footfall counters balance between ‘in’ counts and ‘out’ counts.

  • Anonymise

    Anonymise– to carry out a process or organise in such a way as to preserve anonymity. A process often required when using video based counters in order to protect the identity of people passing through a count zone. This functionality has been built into the Brickstream 3Dpeople counters that Axiomatic use.

  • Automatic visitor counter

    Automatic Visitor Counter – a device which replaces the need to manually count the number of people visiting a site. An automated visitor counter monitors and reports on the number of people passing ‘in’ or ‘out’ of an entrance.

  • Axiomatic Technology Ltd

    Axiomatic Technology Ltd. – technical development company established in 1994 specialising in hardware and software development of footfall technology, occupancy management, space management, desk counting, and motion control systems.

  • BACnet

    BACnet – Building Automation and Control Networks. This is an ISO standard for joining together BMS controllers and devices over a network that is dedicated to the BMS. This enables HVAC to be centrally controlled and monitored to make huge efficiency savings and measure HVAC usage.

  • Beam Counter

    Beam Counter- a basic form of break-beam people counting technology using either a single or dual infra-red beams and a reflector or receiver to monitor visitor counts as people break the infra-red beam(s). Such counters are suitable for monitoring basic footfall trends, but their accuracy depends on the environment where they are mounted, the width of the entrance and the volume of traffic. As they will not count two people side-by-side, such counters should not be used for occupancy counting or event management.

    HVAC – The general term for Heating, Ventilation and Air conditioning. These are the main areas of energy consumption in a University or office environment and minimising waste can result in huge cost savings.

  • Increase retail conversion rate

    Increase retail conversion rate – Every retailer wants to increase their sales. This can be done by increasing the footfall into the store, or increasing the basket size of each customer, or alternatively by ensuring that more potential customers who visit the site receive the right level of customer service to feel happy to buy something. Increasing the retail conversion rate of your store means getting more sales per prospective customer that enters the site. A small increase in your retail conversion rate can have a larger impact on improving your bottom line.

  • Manual Count Survey

    Manual Count Survey – A process where trained staff visit a shopping centre, town or specific venue in order to manually count the number of people. Such studies offer the ability to break down footfall into demographic groups highlighting the age, sex and ethnicity of footfall traffic. However, such studies are labour intensive, expensive, and offer only a brief snapshot of footfall traffic and customer behaviour within a specific location. The results of such studies are highly dependent on the skills and concentration of those conducting the counting survey, and as such are often difficult to verify.

    manual-count-survey

  • Manual Counting

    Manual Counting – Using staff to count the number of visitors into a site.

  • Marketing Performance Measurement and Management (MPM)

    Marketing Performance Measurement and Management (MPM) -is a term used by marketing professionals to describe the analysis and improvement of the efficiency and effectiveness of marketing. This is accomplished by focus on the alignment of marketing activities, strategies, and metrics with business goals. It involves the creation of a metrics framework to monitor marketing performance, and then develop and utilize marketing dashboards to manage marketing performance. It focuses on measuring, managing, and analysing marketing performance to maximize effectiveness and optimize the return of investment (ROI) of marketing. Three elements play a critical role in managing marketing performance—data, analytics, and metrics. Although brand recognition may form part of the purpose of marketing, for a retailer, an increase in sales and profits provides the key ROI. However, an increase in sales transactions alone does not give a full picture of the effectiveness of a marketing campaign. If sales transaction have gone up by 10%, but store footfall has actually increased by 100%, then the campaign has been highly effective, but other factors have reduced the potential ROI. Thus the use of data from people counters to add footfall metrics as part of the MPM is key to understand the true effectiveness of a marketing campaign.

  • Missed Opportunities

    Missed Opportunities– refers to those potential customers who visit a store but leave without making a purchase due to excessive queue length or queue waiting times, lack of available staff, pricing or product availability.

  • Nightclub Counter

    Many premises such as nightclubs need to monitor their occupancy to satisfy council regulations.  An automated system offers a far more convenient and accurate method of achieving this than door staff using manual clickers.

  • Occupancy

    Occupancy– the total number of people in a specific space, calculated by the total number of ‘in’ counts minus the total number of ‘out’ counts at any given time, or by the use of Brickstream Zone tracking technology that can analyse the total number of people within view of a counter (up to a maximum area of 6 square metres per counter dependant on the mounting height of the equipment.)

  • Occupancy Accuracy

    Occupancy Accuracy– occupancy accuracy is achieved by using overhead counters with accurate and consistent flow-rate accuracy. Occupancy accuracy can be subject to cumulative errors due to slight inaccuracies inherent in all existing people counting technologies. Such inaccuracies are exacerbated by low maximum capacities combined with short average dwell times and high footfall, and high volume traffic flow rates. In order to manage this Axiomatic carefully monitor the accuracy of the counters under different conditions to apply the relevant factors to ‘in’ or ‘out’ counts in order to balance potential errors, and are able to inform clients of the expected tolerance of a system to ensure that decisions are made based on understood data.

  • Occupancy Management

  • Refining Opening Hours

    Refining Opening Hours– The process of studying customer traffic & sales transactions, compared to staffing costs and business overheads associated with a site being open, to identify the times when it becomes profitable to keep a site open, and when it is best to close due to lack of potential customers. Assessing footfall and passing traffic gives a more accurate measure for determining opening hours and maximising sales.

  • Remote Monitoring

    Remote Monitoring– A service offered by Axiomatic to help check that our clients people counters are connected to the network, and are functioning correctly. This process automatically flags any correction errors and can highlight specific accuracy problems. Remote access to people counters also allow Axiomatic engineers to log into a counter see check the view of the count zone, and manually assess the accuracy of a counter.

  • Retail Footfall

    The number of potential customers entering a retail environment.  This kind of data can be used against sales figures to give conversion rates.

  • Retail footfall index

    Retail Footfall Index – a regional and national comparison of footfall statistics from a number of sites across a country.

  • SQL database (MS SQL, MySQL)

    SQL database (MS SQL, MySQL)– SQL is ‘structured query language’ and is an industry-standard database language. A database is usually used to store the people count data in a way that can be queried so that questions such as “how many people entered such-a-zone last week?” or “how does the footfall at one site compare to another?’ Such flexible structure allows users to import, compare, query and report on multiple metrics. There are two main variants of a SQL database: MySQL and Microsoft SQL. There are other variants from Oracle, and other software vendors.

  • Staff Planning

    Staff Planning– is a continuous process of shaping the staff profile to ensure that it is capable of delivering business objectives and maintaining a high level of customer service to maximise sales conversion ratios in retail, and customer satisfaction in service industries. The use of footfall data to help predict peaks and troughs in customer numbers can help a business reduce staff costs during periods of low footfall, and maximise customer service and profit during periods of high footfall where customer service may suffer due to under-staffing.

  • Stereoscopic

    Stereoscopic– having two lenses to facilitate the ability to create 3-dimensional vision creating an image with both depth and shape. Stereoscopic video counters like the Brickstream 2300 use this ability to achieve more accurate people counting.

  • Tailgating

    Tailgating– describes the behaviour of one person directly following another through security gate. This is typically a problem with swipe-card access-controlled doors, where one person swipes his card, and another follows.  An electronic tailgate monitor can instigate a tailgate alarm when two people try to pass through a security gate simultaneously. The Irisys Thermal counter can be deployed as tailgate detection system and can be integrated with building security systems to ensure that even when security staff are distracted, non-accredited visitors cannot pass into secure areas without detection.

    tailgaiting

  • Tally Counter

    Tally Counter– a basic manual hand-held counter where a member of staff clicks every time a person passes. Such counters are labour intensive and subject to significant inaccuracies due to limited concentration spans, distractions and a lack of understanding of the importance of the counts. Often used by pubs and nightclubs many councils and licensing authorities are now insisting that the capacity of venues is managed with more reliable and auditable technology

    manual-count-survey

  • Thermal Counter

    Thermal Counter– a specific type of counter using proprietary technology, manufactured by Irisys. This type of counter is mounted on the ceiling above an entrance and counts people by monitoring the difference between the background temperature and the temperature of count targets passing underneath. As such, unlike many standard video counters, the IRC3010 thermal counter is not affected by ambient light. These counters are commonly used within retail stores, shopping centres, art galleries, visitor centres and libraries. Irisys also produce a version of the counter which is capable of monitoring tailgating through turnstiles to assist with building security management.

  • Tolerance

    Tolerance- the agreed, accepted and identified accuracy of a counting system once installed.

  • Traffic Density

    Traffic Density– The number of people passing under a people counter, within a specific space at any one time.

  • Traffic Patterns

    Traffic Patterns– the historical peaks and troughs in footfall rates.

  • Under-counting

    Under-counting– the propensity for some people counting devices to count fewer people than are actually passing through the counting zone. This is a specific weakness where Beam Counters are used across a wide entrance. However, both thermal and video counters can also be subject to under-counting when traffic density reaches extremely high levels. Consistent under counting can be compensated for by adding a factor to each set of counts e.g. daily footfall + 10%.

  • University Space Management

    University Space Management – A system developed by Axiomatic using a range of people counting technology, deployed across teaching space and other key student areas within univeristies, to gather data of peak occupancy, frequency of use and to caclutate accurate space utilisation data.

  • Utilisation

    Utilisation is the metric for space usage calculated by looking at the average room occupancy and room use frequency.

  • Velocity Filter

    Velocity Filter – a people counting algorithm that can define which targets are counted based on speed of transit through the counting zone.

  • Video Counter

    Video Counter– a people counting device based on a standard video lens. Usually, analysing footfall targets through black and white images as these offer greater levels of contrast. The majority of video based counting systems are subject to changes in ambient light and shadow which can create problems in accuracy or data consistency. People counting systems based on standard CCTV systems are usually a bolt-on to the CCTV package and as such rarely offer accurate counts, especially where the cameras have not been positioned directly above an entrance for this purpose. CCTV cameras are usually positioned to see people’s faces, and are therefore subject to occlusion when tasked with counting. Unlike many video based counting systems, the Brickstream counter overcomes any problems with ambient light and shadow and occlusion by using dual-lenses and sophisticated people counting algorithms to achieve high count accuracy.

  • Video Counting

    Video Counting describes the use of video technology to count people or objects. CCTV based systems tend to use ‘bolt-on’ software features with background processing, and are subject to environmental factors rarely offering consitent or accurate counts. More purpose built video counters use on-board processing and offer higher levels of accuracy, however, most single lens video counters fail to reach favourable levels of accuracy or consistency.

  • Video Validation

    Video Validation– a facility enabled on the Irisys Dual-View IRC3030 thermal people counter and the Brickstream 2300 video counter which enables recording of a video stream alongside footfall data, allowing the video, stored count data and diagnostic information to be polled via a single IP data stream.

  • Visitor Counter

    Visitor Counter – a device designed to count the number of people entering a public venue.

  • Weather Effect

    Weather Effect – the effect that weather has on the footfall trends of various sites, depending on their; purpose, stock and location. For instance on a rainy day footfall may increase at a sheltered Shopping Centre, or for Outdoor Leisure stores, or a shop selling umbrellas, but fall for normal high street stores. The effects on footfall of good or inclement weather upon a site will vary depending on the nature and location of that site. By assessing the affect weather on footfall managers can estimate the quantitative traffic response and make suitable staffing adjustments.

  • Workforce Management

    Workforce Management– scheduling staff hours to maximise efficient use of office space, especially where hot-desking and flexible workspaces and break-out areas are in use. Alternatively this phrase can relate to scheduling staff to maximise sales conversion in a retail arena.

  • Workplace Management

    Workplace Management– People counters can be deployed to assist with workspace management by showing peaks and troughs in office occupancy throughout each day, week and month to show the percentage use of an office space, against its designated capacity. Most office space management analysis is either taken from anecdotal evidence, where each department may have a vested interest in protecting their space and reporting over-use, or on manual count which are both labour intensive and give only a snapshot of the actual level of use. As the cost of running a single office workstation is estimated at £7,000 per annum, many organisations look to consolidate space. People counters offer an objective, consistent and clear overview across time to provide solid data to efficiently manage desk space and inform business decisions with regards to consolidation or expansion of premises.
