How to Count Foot Traffic With Just Your Phone

You do not need a sensor, an installer or a landlord's permission to count foot traffic with your phone. The camera already in your pocket shoots video that is more than good enough to count pedestrians from — the trick is filming the right thing, for the right window, in a way software can measure honestly. This guide shows entrepreneurs and brokers exactly how to capture usable footage of a storefront and turn it into a real number, without buying any hardware.

It is part of our wider foot traffic study guide, which covers the whole pre-lease decision. Here we stay hands-on: point, film, upload, count.

Key takeaways

• Any modern phone can capture footage good enough to count foot traffic — no hardware required.
• Film a steady, slightly elevated view across the pavement, covering your real trading hours.
• A short clip is a spot reading; a representative multi-day sample is what earns a projected daily estimate.
• Use a phone for snapshots, a fixed camera for unattended multi-day coverage, and an upload for footage you already have.

Why you can count foot traffic with your phone

Traditional people-counting needs a device mounted above a doorway inside a unit you occupy. That is useless when you are still deciding whether to lease the place. Filming from the public pavement sidesteps the whole problem: you can measure a storefront you have not rented, from across the street, on any afternoon you happen to be scouting.

The counting itself does not care whether the pixels came from a $30,000 sensor or an iPhone — it detects people, tracks them, and counts each one that crosses the line you draw. So the only thing that matters is capturing clean, representative footage. Do that well and you measure footfall without hardware for the price of a coffee.

Step 1: Frame the shot

• Get a little height. A view from slightly above head height — a first-floor window, a raised step, a phone on a small tripod on a ledge — separates people better than a ground-level shot where bodies overlap.
• Shoot across the flow, not down it. You want people crossing your frame left-to-right (and right-to-left), so a line drawn across the pavement catches each one cleanly. Filming straight down a street packs everyone into a distant blur.
• Fill the frame with pavement, not sky. Keep the stretch of footpath you care about large in the shot. If pedestrians are tiny specks, they are hard to count reliably.
• Hold it steady. Prop the phone against something or use a cheap tripod. A locked-off shot beats a handheld one every time.

Step 2: Film a representative window

The single most common mistake is filming for two minutes on a Saturday and treating it as the truth. A short clip is a spot reading, not a day — and we label it that way rather than pretend otherwise.

• For a $49 Spot Check, up to 60 minutes during a genuinely busy period is enough to see the shape of the traffic and get a city percentile.
• For a decision, capture the hours your business would actually trade, across at least one weekday and one weekend. A café should film mornings and lunch; an evening venue should film evenings.

Why it matters: the software can project a daily or weekly estimate from a sample, but the honesty of that projection depends on how representative your footage is. Cover more real trading time and the confidence tier rises from a cautious spot reading to a solid, projectable estimate. The mechanics are explained in reading your Location Score.

Step 3: Upload and draw your line

Once you have the clip, upload it and mark the exact stretch of pavement that matters — usually the line right across the door, not the whole street. Getting this line right is what separates a clean count from a noisy one, so we gave it its own guide: how to draw a counting line.

The system then detects each pedestrian, tracks them across frames, and counts every crossing by direction. You get an hourly profile, a weekday/weekend split, and — for a full study — a Location Score.

Phone, camera, or upload: which to use

Your phone is the fastest start, but it is not always the right tool. Here is the honest split.

Use your phone when you want a quick snapshot, you are physically at the location, and you only need a short representative window. It is perfect for a first look and for a quick Spot Check.

Use a fixed IP or CCTV camera when you need unattended coverage over several days — the thing your phone cannot do because you will not stand there for a week. If the building already has a camera pointing at the street, or the landlord will share an RTSP feed, that is the cleanest path to a full 7-day sample.

Use a file upload when you already have footage. That includes an exported clip from the landlord's own camera, a previous recording, or video a broker captured on a site visit. If it is a video file, it can be counted.

Most serious pre-lease studies combine them: a phone Spot Check to decide the address is worth a closer look, then a multi-day camera or upload for the number you take to the negotiating table. When you are ready, start with a $49 Spot Check and see what your street actually delivers.

A note on privacy

Filming a public street to count people is not the same as surveilling them. We count silhouettes, not faces — no identities are stored, and source video is deleted after processing. If you are wondering about the legal side, we cover it in full in is video people counting GDPR compliant.

Frequently asked questions

Can I really count foot traffic with just my phone? Yes. Any modern phone shoots video good enough to count pedestrians from. You film the storefront for a representative window, upload the clip, draw a counting line, and the software counts every crossing. No sensor or install is involved.

How long should I film for? For a quick read, up to 60 minutes during a busy period is enough to see a pattern. For a decision, film across the hours your business would trade on at least one weekday and one weekend, so a representative sample can be projected with a confidence interval instead of guessed.

Will a shaky or angled phone video still work? Usually, within limits. A steady, slightly elevated view across the pavement counts best. Our quality check flags footage that is too dark, too shaky or too zoomed-out and tells you how to fix it before you pay for a full study.

When should I use a fixed camera or an upload instead of my phone? Use your phone for quick snapshots and short checks. Use an existing IP or CCTV camera when you want unattended multi-day coverage, and use a file upload when you already have footage — for example the landlord's own camera feed exported to a clip.
