Analytics+ Functions
Smart Plan Schedule
Enable Analytics+ functions depending on a user-defined
schedule. Allows the camera to switch analytic functions
based on time.
Perimeter Protection
• Detects human or vehicle violations using the following
methods:
Tripwire: a target crosses a defined line.
Intrusion: a target enters or exits a defined perimeter.
• Monitors a combination of nine (9) detection methods.
• Search and retrieve video based on target type.
People Counting
• Delivers accurate flow statistics from the following
methods:
Line Crossing: counts a person as they cross a
threshold in a defined direction.
Region: counts the number of people in a defined
area.
• Counts people simultaneously from four (4) threshold
lines and four (4) defined regions.
Queue Management
• Monitors four (4) user-defined regions where people wait in line (or queue). Issues an alarm for the following triggers:
People in Line: the number of people in line exceeds a minimum threshold.
Wait Time: time a person waits in line is greater than the minimum queue time.
Face Detection
Detects and captures a snapshot of a human face within
a scene.
Smart Motion Detection+
• Differentiates between and classifies human and
vehicle objects.
• Filters false alarms due to leaves, lights, animals, and
other inconsequential objects.
• Extracts human or vehicle objects from recorded video
for quick target search and retrieval.
Intelligent Video System Functions
IVS triggers an alarm and takes a defined action for the following events:
Standard Features
• Tampering with the camera.
• Error writing to an onboard Micro SD card.
• Error sending or receiving data over the network.
• Unauthorized access to the camera.
• IP Address Conflict
Premium Features
Missing Object
An object is missing from a designated area
Abandoned Object
An object is placed in a designated area where no object
should be.
Scene Change
A person or object moves the camera to change the scene or covers the camera to obscure the scene.
Fast Moving
Target exceeds a set speed when exiting a defined area
Parking Detection
Vehicle remains in a defined area without motion for a set period of time.
Crowd Gathering
Specified number of people remain inside a defined area for a set time.
Loitering Detection
Target is in motion inside a defined area longer than a specified amount of time.
1. The DORI distance is a measure of the general proximity for a specific classification to help pinpoint the right camera for your needs. The DORI distance is calculated based on sensor specifications and lab test results according to EN 62676-4, the standard that defines the criteria for the Detect, Observe, Recogniz and Identify classifications. 2. Pair a Smart Motion Detection camera with a Dahua recording device that also offers SMD functionality to take advantage of SMD alarm filtering and object classification when searching and playing back recorded video.

Data Sheet
Quick Start Guide
User Manual
WizMind Series devices offer the full complement of Dahua Analytics+ functions for comprehensive, human-oriented analytic solutions. WizMind Series products deliver perimeter protection, vehicle and crowd density statistics, video metadata, and advanced people counting with heat map functionality. WizMind is ideal for complex applications with demanding requirements that need advanced analytic capabilities.
Functions:
Perimeter Protection
Dahua Analytics+ includes Tripwire and Intrusion functions that offer custom tripwires based on object type for automation in limited access areas. Perimeter Protection requires less pixels to detect an object to deliver improved accuracy and decreased false alarms due to lights, weather, trees, or animals.
People Counting
The camera uses complex real-time people counting algorithms to deliver accurate flow statistics from two distinct people counting functions, Line Crossing and Regional. The line crossing function counts the number of people crossing a defined line, and the regional function counts the number of people in a distinct, user-defined area. People counting is ideal for measuring the number of customers entering or exiting a location and to monitor groups of people in a distinct location.
Smart Motion Detection+
Smart Motion Detection+, a component of Dahua’s Analytics+ technology, improves alarm accuracy and decreases the number of false alarms. The advanced SMD+ algorithm analyzes a scene for human or vehicle motion, while filtering out other motion due to trees, leaves, animals, weather, and triggers an alarm when detected. SMD+ also saves time when searching recorded video by filtering false alarms and allowing quick retrieval of an alarm due to a person or vehicle.
Night Color Technology
The Night Color camera incorporates white-light LEDs to offer full-color images in total darkness, as well as an effective visual deterrent. This technology provides smart illumination where the camera automatically activates the white-light illuminators when ambient light levels fall and adjusts exposure time and LED intensity to prevent overexposing the image.
ArcticPro
The Dahua ArcticPro Series of extreme-environment cameras combine temperature-tolerant components with a waterproof enclosure to ensure flawless operation in temperatures as low as –40° C (–40° F) without the need for an internal heater. The lack of a heater reduces the camera’s power consumption and saves operating costs. For applications that demand high-resolution video with advanced features in extremely cold environments, the Dahua ArcticPro Series offers a camera to satisfy the most demanding requirements.
Enhanced Power over Ethernet (ePoE) Technology
Dahua’s innovative ePoE technology offers a plug-and-play solution to transmit power and data over long distances via Ethernet or coaxial cables, reducing installation time and saving money. ePoE technology is a viable, cost-effective solution for extending transmission distances and for converting existing, coax-based analog systems into IP systems.
Cybersecurity
Dahua network cameras are equipped with a series of key cybersecurity technologies including: security authentication and authorization, access control, trusted protection, encrypted transmission, and encrypted storage. These technologies improve the camera’s ability to prevent malicious access and to protect data.
Environmental
Subjected to rigorous dust and water immersion tests the camera suitable for the most demanding outdoor applications. The camera carries an IP67 rating that ensures protection from total dust ingress and protection from water immersion between 15 centimeters and 1 meter in depth.
