Door counting for shops, venues and public spaces
See how many people are inside. No camera.
A small sensor above your door counts people in and out. You see the numbers on your phone: who is inside right now, your busy hours, your quiet days.
Tallora in one minute

This is Tallora. It tells you how many people are inside, without a camera.
Most shops, gyms and venues cannot say how many people walked in today, or which hour was the busiest. So rosters and opening hours get set by guesswork.
Tallora is a small sensor that sits above your door. It measures distance, not faces, at sixty four points, fifteen times a second.
This is everything it sees. The bright shapes are heads and shoulders, and nothing in it can show who someone is.
It finds each head, follows it through the doorway, and counts it in or out. Two people side by side are two people. A trolley is not a person, and someone who turns back is not counted.
The counts go to a simple page on your phone. You see how many people are inside right now, today hour by hour, and the busiest times of your week.
No image is ever taken, so there is nothing to leak and nothing to blur. Only the numbers leave the sensor.
Tallora is made in New Zealand by Salix. We are looking for our first pilot sites.
How it works
- 1
A small sensor above your door
It measures distance at 64 points, fifteen times a second. That is heights, not a picture: nothing it records can show who someone is.
- 2
It counts people in and out
It finds each head, follows it through the doorway and counts it in or out. Two people side by side are two people. A trolley is not a person, and someone who turns back is not counted.
- 3
You see it on your phone
How many people are inside right now, today hour by hour, the last 30 days, and the busiest times of your week. "Inside now" starts again from zero every morning.
What you see on your phone
One page, no app to install, and it updates by itself every 30 seconds.
Inside right now
How many people are in, counted in and out since opening. Handy when a room has a limit.
Today, hour by hour
When the rush started, when it stopped, and whether today is ahead of a normal day.
The last 30 days
Quiet days and busy days side by side, so a change in trade shows up early.
Your busiest times
Each weekday and hour on one grid, for rosters and opening hours.
Where it fits
Anywhere with a door and a reason to count.
Shops and chains
Staff the busy hours, and compare stores when head office asks.
Cafés and restaurants
See the real lunch rush, not the one you remember.
Gyms and studios
Know how full the floor is before members complain.
Venues, churches and halls
Keep an eye on how many are inside against the room limit.
Libraries, museums and councils
Visitor numbers for the funding report, without a clicker at the door.
Offices and schools
How much the building is really used, day by day.
Private by design, not by promise
Cameras that count people still see faces, and then someone has to promise what happens to the footage. Tallora uses a depth sensor, so there is no footage. There is nothing to leak, nothing to blur, and nothing a customer needs to worry about.
How we handle data- No camera. It measures distance. There is no picture to take.
- Nothing personal. It knows a head crossed the door, never whose.
- Counts only. In normal use, only the in and out totals leave the sensor.
What people use the numbers for
Rosters
Put staff on when the people are actually there.
Opening hours
See whether the first or last hour is worth opening for.
Promotions
Know whether a sign or a sale brought more people through the door.
Busy limits
Know how many are inside when a room has a limit.
Questions
Does it use a camera?
No. It is a depth sensor: it measures how far away things are at 64 points and nothing else. There is no lens forming a picture, so an image of anyone cannot exist, even by accident.
How accurate is it?
We are measuring that now, at real doors, against people counting by hand. We will not quote a number until we have measured one. Pilot sites get a hand-counted check every week, and we share the result with you.
What does my door need?
Somewhere to mount the sensor above the door, ideally 2.7 m or more above the floor, a power socket within a couple of metres, and Wi-Fi. One sensor covers a door up to about 1.5 m wide. A lower frame or a wider door may need a second sensor or a mount just inside.
Who can see the numbers?
You, through a private link, and Salix, so we can keep the sensor working. We do not sell or share your counts.
Does it count children?
It counts heads more than about 95 cm off the floor, which is how it ignores trolleys, prams and dogs. A small child walking close beside an adult is the hardest case for it, and one of the things we are measuring at real doors.
Does it work in the dark, or in bright sun?
The sensor makes its own infrared light, so a dark doorway is no problem. Strong sun shining straight onto the floor under it is the harder case, which is why we check each door for sun before we install.
What about groups and couples?
It follows each head separately, so two people walking side by side are two people. A packed doorway at a busy moment is harder for any counter, and we test that on purpose.
Can it leave out staff?
Not yet. Everyone who crosses the door is counted, staff included. If staff use a back door, the front door counts are customers only.
Who installs it?
We do, during the pilot. It is fixed above the door and runs from a normal plug, so there is no electrician and no wiring to change.
What does it cost?
We agree the terms with each pilot site in writing before anything is installed, and we tell you any price before you commit to anything.
What happens to our counts if we stop?
They are yours. We send you a copy as a spreadsheet file if you want one, and delete them if you ask.
We are looking for our first pilot sites
A shop, café, gym, venue, library or office in New Zealand, and someone who would like to know their numbers. Tell us a little about your door and we will tell you whether it suits.
