Dahua Crowd Distribution & Heat Map Setup
Complete Web 5.0 Guide | Full Extended Long Version + Official Manual Page & Figure Numbers

Dahua Crowd Distribution and Heat Map are two of the most valuable advanced AI analytics features built into modern Dahua Web 5.0 network cameras. Unlike standard motion detection, IVS tripwire, or intrusion detection which only focus on security alarms, these functions are designed for business intelligence, pedestrian behavior analysis, crowd safety management, and operational data statistics. They turn ordinary surveillance cameras into intelligent data analysis devices that visualize visitor activity, measure crowd density, track pedestrian distribution across different areas, and provide actionable historical reports for management decisions.

Heat Map technology uses intelligent AI algorithms to calculate pedestrian activity intensity across every pixel of the camera view. It displays real-time color-coded activity levels, where red represents highly active crowded hotspots, yellow indicates medium activity areas, green shows low activity, and blue means idle, unused areas. Crowd Distribution takes analysis further by dividing the monitoring scene into multiple independent statistical zones, counting pedestrian entry, exit, residence time, visitor proportion, and real-time crowd quantity in each separate area. It can also trigger automatic safety alarms when crowd density exceeds preset safe limits, which is extremely important for public venues, construction sites, shopping malls, and crowded indoor environments.

This fully extended guide strictly follows the official Dahua Network Camera Web 5.0 Operation Manual. It includes detailed full-step configuration, complete parameter explanations, arming schedule setup, real-time and historical data viewing, alarm linkage configuration, optimization best practices, comprehensive troubleshooting, and 100% accurate official manual page numbers + standard Figure names. You can directly insert corresponding manual screenshots into your blog article without any modification. This guide applies to all Dahua AI bullet, dome, turret, and PTZ cameras with Web 5.0 firmware and built-in crowd analysis algorithms.

Part 1: Detailed Extended Heat Map Full Setup Guide

Heat Map continuously analyzes pedestrian activity intensity in the designated monitoring area in real time. It automatically accumulates activity data, displays dynamic color heat overlays on live view, and saves complete historical heat map records for later review and analysis. It is the most intuitive tool to understand which areas are popular and which areas are unused in your monitoring scene.

Step 1: Enable Heat Map Core Function

Log into Web 5.0 interface, navigate to AI → Smart Plan → Crowd Analysis
Find the Heat Map module on the page
Toggle the Heat Map Enable switch to ON status
Click Apply button to activate the basic heat map analysis function

Step 2: Draw Exclusive Heat Map Detection Zone

Heat Map will only analyze pedestrian activity inside the zone you draw, and completely ignore all movements outside the zone. Proper zone drawing is the key to accurate data and reducing invalid statistics.

Click Zone Setting / Draw Zone button to enter zone editing mode
In the live preview window, use left mouse click to draw a closed polygon detection area
Please manually exclude sky areas, trees, moving roads, reflective walls, and other non-pedestrian interference areas
After finishing drawing, right-click mouse to confirm and save the detection zone

Step 3: Configure Complete Heat Map Advanced Parameters

This section defines how the camera collects, updates, and filters heat map data. All parameters are explained in detail below:

• Statistical Period: Data refresh and update interval, optional 5 seconds to 30 seconds. Shorter period means more real-time data; longer period means more stable statistics. 10 seconds is recommended for most retail scenes.
• Heat Map Sensitivity: Adjustable from level 1 to level 6. Higher sensitivity responds to slight pedestrian movement; lower sensitivity filters tiny walking vibrations.
• Save Historical Heat Map: Must be enabled to store daily historical heat map data for later query and export.
• Non-human Filter: Highly recommended to enable. The AI algorithm will only detect human activity, automatically ignore vehicles, cats, dogs, birds, insects, and floating debris.

Step 4: Configure Heat Map Arming Working Schedule

You can customize the time periods when Heat Map runs automatically. For retail businesses, it is recommended to enable only during business hours and disable during off-hours to save storage space.

Click Time Plan / Arming Period to enter schedule setting page
