How it helps

Know Exactly What Is Happening in Your Space

Zone Monitor watches your camera feeds and counts people as they move through doorways, gates and walkways. It shows how full each area is, how long people stay, and when crowds start to build.

It runs on a computer at your site and works alongside your existing video system, which keeps recording as normal. Cronus sets it up, draws the counting lines and zones for you, and supports it 24/7. It is already counting foot traffic in Detroit’s Greektown district.

What it measures

Everything You Need to Understand Foot Traffic

Every metric is available per camera, per zone and for the whole site.

In and Out Counts

Draw a counting line across any door, gate or walkway. Zone Monitor counts every person crossing, in each direction.

Live Occupancy

See how many people are inside each zone you draw, right now, plus the average and peak for every period.

Visits and Dwell Time

Know how many people enter an area and how long they stay, so you can spot lingering and plan staffing.

Crowd Alerts

Get an alert when a zone holds too many people, sent to your dashboard, Microsoft Teams, Slack or email.

Reports and Exports

Stats by the minute, hour, day, week or month, scheduled email reports and one-click Excel exports.

Live Annotated View

Watch any camera with the counting lines, zones and tracked people drawn on top, so you can see exactly how it counts.

How it counts

Counting Lines and Zones, Explained

Counting lines are drawn across a doorway, gate or sidewalk. Every time a person crosses the line, Zone Monitor adds one to In or Out, depending on the direction.

Zones are areas you draw on the camera view, like a patio, a lobby or a block of a street. Zone Monitor keeps a live count of how many people are inside each zone and how long they stay.

People are tracked as anonymous shapes from frame to frame, so the same person is not counted twice, and nobody is identified. Lines and zones can be added or moved at any time.

Example: a counting line on the entrance and an occupancy zone on the patio.

Your dashboard

What Every Number Means

Pick any camera, zone or the whole site, then choose minute, hour, day, week or month.

In and Out

Every person who crosses a counting line, in each direction. Lines go across doors, gates, stairs or sidewalks.

Net Traffic

In minus out for a period, so you can see whether a space is filling up or emptying out.

Occupancy Now

How many people are inside a zone at this moment, updated live.

Average and Peak Occupancy

The typical and highest number of people in a zone for any hour, day or week, and when the peak happened.

Visits

How many separate people entered a zone, even if they never crossed a counting line.

Dwell Time

How long people stay in a zone on average, so you can spot lingering or long waits.

People Seen

The total number of different people a camera saw during a period.

Site Totals

Every number rolls up per camera, per zone and for the whole property.

Examples

How Customers Use Zone Monitor

The same cameras answer different questions for different businesses.

Entertainment district

Greektown, Detroit

Zones cover busy blocks on Saturday nights. When a block holds more than the set number of people for 10 seconds, security gets a Teams alert and can send staff before a crowd becomes a problem. AI also flags open intoxicants and loitering. Weekly reports show which hours and streets are busiest.

Bars and restaurants

Capacity limits

Counting lines on every door keep a live occupancy number next to your posted capacity. An alert at 90% lets the door staff slow entry before you hit the limit, and the night’s peak is saved for your records.

Retail stores

Staffing and conversion

Hourly door counts show exactly when shoppers arrive. Compare them with sales to see your conversion rate, and schedule staff for the hours that matter instead of guessing.

Stadiums and events

Gates and crowd flow

Counting lines on each gate show how fast fans are entering. If one gate is backing up, the operations team sees it live and opens more lanes or redirects the crowd.

Parks and public spaces

Attendance you can prove

Daily and event attendance numbers make it easy to report results to sponsors, boards and grant programs, and to plan programming around the busiest days.

Offices and campuses

Building occupancy

Know how many people are in each building or floor right now and through the week, to plan cleaning, security staffing and space use.

Reports

A Weekly Report in Your Inbox

Zone Monitor can email a summary every morning, week or month. You see total traffic, how full each zone got and when the peaks happened, without logging in. Every report can be exported to Excel, and the data is available through an API for your own systems.

Built for security teams

Alerts That Reach the Right People

When a zone holds too many people for 10 seconds or more, Zone Monitor sends an alert to the dashboard and to Microsoft Teams, Slack or email. Unanswered alerts can escalate, and camera health is watched around the clock.

A plain-English search lets your team ask questions like “crowd alerts on Saturday night” and jump straight to the events that matter.

Intoxication

Spots people stumbling or lying down who may need assistance.

Crowd buildup

Warns when a block or zone gets too dense, using live people counts.

Fewer false alarms

Every flagged event can get a second check by AI before it is logged, and each alert includes the camera view so your team sees exactly what happened before responding.

Coming next

Weapon detection and thermal sensors are being added to the same platform. Ask us about adding any detection to your site.

Questions

Zone Monitor FAQ

Can Zone Monitor detect open intoxicants and loitering?

Yes. Zone Monitor uses AI video analytics on your existing cameras to detect open intoxicants, loitering, fights, slip-and-falls, intoxication and crowd buildup, and sends alerts with the camera view to your security team. These detections are running today in the Greektown Smart District in Detroit.

Does Zone Monitor work with Project Green Light?

Yes. Zone Monitor runs on the same cameras that stream to the Real Time Crime Center at Detroit Police Department Headquarters through Project Green Light Detroit, so police get live video while your team gets counts and alerts.

What is Zone Monitor?

Zone Monitor is Cronus’s smart camera analytics service. It turns your existing security cameras into people counters that measure foot traffic, occupancy and dwell time, and alerts your team when an area gets too crowded.

Do I need new cameras?

Usually not. Zone Monitor works with standard IP cameras, including Axis, Hikvision and Hanwha. It reads the video stream directly, so your current video management system keeps recording as normal.

Does Zone Monitor use facial recognition?

No. Zone Monitor counts and tracks people as anonymous shapes moving through lines and zones. It does not identify who anyone is.

How accurate is the people counting?

In testing, Zone Monitor counted 7 of 7 people walking in and 7 of 7 walking out of a test clip. Accuracy depends on camera placement, so we help position counting lines where people are fully visible.

How far back does the data go?

Minute-by-minute counts are kept for 400 days by default, and you can export any period to Excel or pull it into your own systems through the API.

How many cameras can it handle?

One on-site computer can handle anywhere from about 8 cameras to more than 40, depending on the hardware. We size the system for your site.
