A tenant on the first floor asks for a 15% rent reduction at renewal. Their argument: traffic on their corridor has collapsed since the anchor on the ground floor changed hands. Your leasing manager has a feeling that is not true, a spreadsheet of Saturday car park counts, and no way to prove anything about the first floor specifically. That renewal conversation, repeated across forty or sixty leases a year, is where most of the return on mall visitor analytics actually sits. Not in a dashboard. In the negotiations you can win, and the concessions you stop giving away by default.
This guide sets out where the money comes from, what the system realistically costs, how to build a business case a finance director will sign, and which mistakes make the investment look worse than it is.
Operators who have run counting for more than a couple of years tend to point at the same four sources of value, in roughly this order of size.
The cost is not the sensors. It is the number of places you decide to measure and the quality of the installation. A mall with eight public entrances, three car park lift lobbies and two escalator banks needs a sensor at each, plus cabling, mounting, commissioning and a software subscription. Interior zones for corridor-level leasing data add more. A first-year budget therefore depends far more on your zoning ambition than on the hardware unit price.
A sensible way to phase it: entrances and vertical transport first, because that gives you total footfall, floor-by-floor split and hourly profiles within weeks. Corridor and zone sensors in year two, once leasing has identified which corridors are actually in dispute. Journey analytics, which track how visitors move between zones and how long they dwell, are a third layer. VemTrack covers that layer, including AI-based re-identification so the same visitor can be recognised across camera zones without storing personal identity, which is what makes questions like "what share of anchor visitors reach the food court" answerable.
The numbers below are illustrative, not a promise. Use them as a template and replace every figure with your own.
Take a 45,000 m² centre with 110 units and annual base rent of €22 million. Assume 25 renewals a year and that, today, one in three renewals ends with a concession averaging 6% because the landlord cannot counter the tenant's footfall claim. That is roughly eight concessions on units averaging €200,000 in rent: about €96,000 given away annually. If corridor data lets you hold firm on half of those, the leasing lever alone is worth roughly €48,000 a year, recurring.
Now add marketing. If the centre spends €600,000 on campaigns and events and attribution shows 20% of that produces no incremental footfall, reallocating it is €120,000 of spend that starts working. Add a modest 4% reduction in a €1.5 million soft-services contract from load-based scheduling: €60,000. You are now above €220,000 of annual value against a first-year cost that, for a phased entrance-first deployment, is typically a fraction of that. Most operators who run this exercise honestly land on a payback well inside the first lease-renewal cycle.
Notice what is not in the model: no assumed uplift in tenant sales, no assumed increase in total visitors. Those may happen, but a business case that depends on them is a business case that gets challenged.
Here is something installers see constantly and business cases never mention. Leases refer to zones, floors and corridors using the naming from the original letting plan. Sensor layouts get designed by whoever is walking the building with the installer. Six months later, leasing wants to defend a rent on "Zone C, Level 1" and the data is labelled by entrance number and column grid. Mapping the two after the fact takes weeks and undermines the first renewal conversation you try to use it in. Before anyone mounts a sensor, sit leasing and the installer down with the lease plan and agree the zone names in the software. It costs an afternoon and protects the single largest source of return.
A related point on the data itself. Tenants will challenge your numbers, particularly when those numbers cost them money. Be precise about accuracy when you present them. Vemco contractually commits to a minimum of 96% counting accuracy, and in practice the figure is typically 98 to 99% where lighting, layout and visitor behaviour allow. Saying "typically 98 to 99%, guaranteed above 96%" is a stronger position in a dispute than a flat claim you cannot defend on a badly lit escalator landing in December.
Fix a baseline before the data changes anyone's behaviour. Record, for the twelve months before go-live, the concession rate at renewal, the average concession size, marketing spend by campaign, and soft-services hours by shift. Then track the same four figures quarterly. That is your ROI report. It is unglamorous and it is exactly what an asset manager needs to show an investment committee.
Two refinements pay for themselves quickly. First, add demographic split to the entrance data so the marketing team can check whether a campaign aimed at a particular age group actually shifted the age profile of visitors that week, rather than relying on agency reporting. Second, give tenants a limited view of their own corridor data. Retailers already using conversion analytics in-store, the way Luksusbaby uses VemCount to watch live conversion rates and visitor demographics, will engage with a landlord who speaks the same language, and that engagement shows up in renewal rates two years later.
If you want to run this ROI model against your own centre, with your renewal calendar, your entrance layout and your marketing budget, contact Vemco Group and ask for a mall footfall business-case session. Bring the lease plan.
