Beyond Traditional Security

Premium IVS

All Dahua network cameras offer some or all Premium built-in intelligent Video System Analytics as standard such as: motion detection, tripwire violations, intrusion detection, abrupt scene changes and abandoned or missing objects. Additionally, select IP cameras also come with a range of advanced features for making better business decisions such as basic people counting and providing higher efficiency.


Motion Detection
Video analytics help ensure surveillance images are analyzed in real-time so that users receive an alert once the rule is activated. Motion Detection is an analytic that is triggered when an object moves through any part of the scene. Motion Detection can be set-up to do either a portion or all of a scene and can be designated to varying levels of sensitivity. The higher the sensitivity or the smaller the region, the easier it will be for motion to be detected.


Tripwire
Video analytics are ideal for adding an extra layer of protection by providing alerts to potential security risks. The Tripwire analytic is designed to trigger an alert when an object crosses a user-defined area in a designated direction.

Tripwire is best used in wide, open areas without a lot of coverings, such as an unguarded gate. The Tripwire function can be set-up for entering or exiting in different directions. Additionally, the Tripwire function can also be set-up to record, send a snapshot and to send an alarm according to the judgment result.


Missing & Abandoned
When it comes to a car dealership environment, often lots have so many vehicles that it can be daunting to keep track of them all. In fact, sometimes cars go missing and it isn’t until days or weeks later until someone finally notices. Dealership break-ins are a trend moving upward and according to the NHTSA, a vehicle is stolen every 40.9 seconds.

To combat this problem, the Missing and Abandoned Object video analytic may be useful. This analytic is designed to detect when an object is removed or abandoned from a specific area. Once the area is set up, a time limit can be set to determine how long after an object is either placed in an area or removed that an alarm will trigger. This is ideal for high value objects or areas at high risk for unwanted objects such as dumpsters.


Scene Change
The Scene change functionality is designed to detect if there is a change in the scene previously captured by the camera, such as a person covering or moving the camera to obscure the scene. The camera compares the image prior to the change to that after to determine if the scene is different, if it is an alarm will be triggered.


Intrusion
Video analytics ensure surveillance systems continuously analyze data to send real-time alerts for the things that need attention. Intrusion functionality triggers an alarm when a person or object enters or exits a user-defined area. It can be set up for a defined area within a scene and set to capture entrance, exit, or both, from the defined area. For example, a business owner may use the Intrusion analytic to detect individuals moving throughout his property after hours.

Advanced IVS

Basic People Counting
When video surveillance cameras came onto the market they were used primarily to catch incidents on video. Today, if you are only using these cameras for surveillance you are missing out on how they have evolved into helping businesses maintain efficiency, increase sales and enhance customer service. The basic people counting feature measures the number of customers or visitors in a surveillance scene and stores daily, weekly, monthly, and yearly people flow through a defined scene and produces a configurable report.


Auto Tracking
Automatically tracking individuals or vehicles through a scene can be beneficial to security operators as they watch for an event to unfold. Auto Tracking maximizes the capabilities of a Pan Tilt Zoom (PTZ) camera. Triggered manually or automatically by defined rules, the camera can zoom in and track the defined target in a single scene, panoramic scene, or across multiple scenes. Select Dahua PTZs have this innovative function.


Many Dahua Lite Series cameras feature WizSense Analytics+. WizSense allows customers to focus on humans and vehicles while ignoring irrelevant data such as pets, stray animals, debris and extreme weather conditions.

With easy configuration such as its one-click configuration for Smart Motion Detection (SMD) and a cost- effective price point, WizSense is designed to be simple enough to meet the needs of most general users.

Smart Motion Detection
Motion detection is a great tool for analyzing a scene and sending alerts when motion occurs. But it’s prone to false alarms because let’s face it, there are a lot of things in a scene that can move: a tree branch blowing in the wind, a stray cat, things that aren’t truly a threat. Smart Motion Detection (SMD) is a new technology that mitigates false alarms and keeps your security operations running efficiently.

A deep learning algorithm lets SMD differentiate between human and vehicular shapes within a scene, at up to 95% accuracy. You don’t have to draw lines to define specific areas to be monitored; once you activate SMD with one easy click, an SMD-enabled camera and recorder with SMD firmware will get to work identifying people and vehicles anywhere in the camera’s field of view.

  • 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.

Perimeter Protection
Securing the perimeter of commercial buildings, storage facilities, campuses, utilities, airports, parking lots and garages are a primary concern when it comes to outdoor security. Additionally, protecting people from dangerous or hazardous areas such as lakes and construction sites is also a concern when it comes to protecting the health and safety of others.

Perimeter Protection
can help combat these fears as it can be configured to detect behaviors that would indicate a person is about to or attempting to cross a perimeter. Perimeter Protection enhances the tripwire and intrusion detection functions by including an object filter, a highly accurate way to distinguish between people and vehicles without false alarming on nonessential objects such as weather and small animals. Objects that cross a defined line can be categorized as humans or motor vehicles, making incidents easier to search for and allowing the option of setting up alerts for specific types of intrusions.

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.

Thermal Features
When it comes to fires, traditional smoke detectors are good for areas that are no greater than 15 feet high. This is because as the ceiling gets higher, the fire size increases until detected. Plus, there is a strong chance that the smoke will become static before it reaches the detector. Additionally, more airflow from the HVAC system will likely impact the smoke by pushing it away from the detector. As a result, the fire will have more time to start burning and spreading until the alarm is sounded. One solution to combat this problem is fire detecting thermal cameras.

Fire Detection
Thermal imaging cameras can detect a rise in temperature over a short time and issue an alarm before the potential fire has time to spread.

Cold/Hot Spot Trace
A fire can destroy multiple buildings in an extremely short time. The value of the property or tangible items destroyed can be tremendous, and the cost of a life is unmeasurable. Thermal imaging cameras can help prevent fires by detecting hot spots before they ignite as it can indicate the coldest and the hottest spot of the scene.

Smoking Detection
Thermal imaging cameras can detect lit cigarettes both during the day and at night and will trigger a pre-determined action (voice prompt, white light) to alert the person of the smoking policy. This feature is ideal for companies or educational facilities that have a strict no smoking policy.

Human/Vehicle Classification
Thermal imaging cameras can detect human or vehicle violations using Tripwire or Intrusion detection methods for decreased false alarms from the things that do not matter.

WizMind, available on select Pro and Ultra Series IP cameras, is a high-end line based on a powerful AI chip and deep learning algorithms for a more efficient security system. WizMind provides comprehensive human-oriented solutions including privacy protection, human video metadata, advanced people counting and more.


Face Attribute Extraction
AI Video Analytics is an important enabler to help improve levels of security. For example, time is of the essence when a video surveillance system captures an incident such as a kidnapping or bank robbery in real-time. The ability to search the scene for people with the characteristics of the assailant could save valuable time in finding and apprehending the suspect.

With various characteristics in the form of metadata, cameras can provide information about a person’s face such as if they have facial hair, glasses, age, gender, expression or if they are wearing a mask.

  • Captures faces, compares to stored images, and produces match statistics.
  • Extracts six attributes and eight expressions (Happy, Calm, Surprise, Sad, Rage) from a face capture.
  • Offers face enhancement, face exposure, and a face angle filter for clear facial images.

Face Detection
Dahua aims to deliver intelligent video system analytics for increased efficiency, reduced costs and to improve safety. Video analytic algorithms use metadata to add sense and structure to a scene. This helps the camera understand what it’s seeing so it can send an alert when a rule is broken or threat is present. Additionally, video footage can be retrieved instantly versus combing through hours of stored data so an operator or authorities can act faster.

Face detection is used to detect whether a face has appeared in a video feed. It has the ability to detect that there is a person in the line of sight of a security camera; however, it is unable to recognize the person. It uses video analytics to detect the shape of a face; specifically, the space between the eyes. Once a face is detected, the camera automatically sends a snapshot to the NVR.


Face Mask Detection
As businesses and organizations adapt to the changing environment in and around their facilities due to the pandemic, the number one thing on their mind is keeping employees and customers safe. As a result, wearing a mask has been adopted as a safety measure in many workplaces. Therefore, cameras with face mask detection have the ability to detect a face and then check for the presence of a face mask. If a mask is not present, the camera will issue a built-in message alerting a person to use a mask. If you do not like the pre-recorded option, it has the ability to customize your own message.


Advanced People Counting – Line Crossing and Regional
When video surveillance cameras came onto the market they were used primarily to catch incidents on video. Today, if you are only using these cameras for surveillance you are missing out on how they have evolved into helping businesses maintain efficiency, increase sales and enhance customer service.

With accurate real-time data, the Advanced People Counting feature allows users to estimate in-store traffic, enhance staff management, evaluate the effectiveness of promotions and alert management when a customer needs help. Advanced 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.
  • Produces daily, monthly, and annual reports for both methods.
  • Counts people simultaneously from four (4) threshold lines and four (4) defined regions.

Crowd Map
Cameras that feature the Crowd Mapping analytic can send an alert to your mobile device when the crowd quantity or density exceeds a set threshold in selected area. For example, the analytic can help detect when public places such as retailers, malls, airports or other areas become over-crowded.

  • Detects crowd density and displays it on a heat map. An alarm is triggered when the crowd quantity or density exceeds a set threshold in selected area.
  • Detects up to 1024 people and can be applied to eight (8) regions.

Vehicle Density
With deep learning algorithms, the Vehicle Density feature analyzes the vehicle situation such as the number of vehicles in a selected area or vehicle congestion in selected lanes.

Vehicle Density includes two rules, Traffic Congestion and Parking Upper Limit.

• Minimum pixel requirement: ≥ 80 pixels
• Applies to 16 regions
• Detection radius up to 80 m (262.47 ft)
Traffic Congestion and Parking Upper Limit are very similar except with Traffic Congestion you can set a time limit starting from 1 to 100 minutes where Parking Upper Limit you can not set a time limit. A mobile alert is sent once the user defined threshold is met.

Traffic Congestion is mainly used in high-altitude road scenes such as if an accident is blocking an intersection due to traffic congestion or if toll plazas are backed up so additional staff can help. An alarm is triggered if the vehicle number and the continuous congestion time in the area simultaneously exceeds the set threshold.

Parking Upper Limit is ideal for parking lot scenarios such as if a car rental depot reaches its capacity for returned vehicles an alarm will trigger alerting management that additional staff is required.

Smart Tracking
Increasing operator efficiency is essential when it comes to monitoring numerous cameras. In fact, after 12 minutes of continuous video monitoring an operator will often miss up to 45% of what’s happening on the screen. With the Smart Tracking feature, Dahua’s integrated multi-sensor PTZ automatically tracks an object by defined rules across all fixed sensors; allowing a higher efficiency for operators.


Heat Map
Heat mapping has made its way into security cameras as a way to enhance business decisions as well as public safety. Traditionally, video surveillance cameras were installed to protect inventory, keep a watchful eye on potential thieves, and for verification of events. However, customer data can now also be obtained from these cameras for in-store analysis such as how well a campaign did, where employees are needed most, and where traffic bottlenecks occur.

Heat mapping is an advanced feature that brings business intelligence to a security system. Intelligent analysis tracks and stores daily, weekly, monthly, and yearly people flow through a defined scene and produces a configurable report. Cameras with the Heat Map feature helps businesses visualize how customers behave, move through the store, and the areas they spend most of their time.

  • Uses collected data to produce a heat map, a two-dimensional representation of data that provides an immediate visual summary of information.
  • Identifies the most active areas of a given location, providing valuable data analysis for commercial applications.

Active Alarm
Although most security cameras are used to deter crime or catch an incident on video, these devices are no longer just for security anymore. In fact, if you have security cameras at your retail location and are only using them for the purpose of security, you are missing out on other creative ways to improve sales and customer engagement. For example, the Active Alarm feature could replace the need for a greeter at smaller companies or ones that are short staffed.

With the Active Alarm feature, a user can upload a custom message to offer a customer greeting such as “Welcome, please sign in and someone will be with you shortly.”

The Active Alarm feature can also be configured with an automatic white-light illuminator when an alarm is triggered or a siren which includes 11 built-in sounds.


Parking Detection
AI Video Analytics is an important enabler to help improve levels of security. For example, many times people leave their vehicles unattended in no parking zones or in an area for longer than the allotted time allowed. Cameras that feature Parking Detection can send an alert to your mobile device when a vehicle remains in a defined area without motion for a set period of time.


Crowd Gathering
Cameras that feature the Crowd Gathering analytic can send an alert to your mobile device when a specified number of people remain inside a defined area for a set time. For example, the Crowd Gathering analytic can help detect when public places such as malls, airports or other areas become over-crowded.

Additionally, the Crowd Gathering analytic can be used to help ensure a riot doesn’t happen. Although sometimes riots erupt unexpectedly, they are frequently tied to planned protests and organized strikes. Unlawful crowds can become disruptive as violence ratchets up. For example, in 2020 large crowds that gathered after the Dodgers and Lakers victories and during major protests against police brutality in Los Angeles, CA devolved into chaos and clashes with police on skirmish lines. Many protesters and police were injured in those incidents, and dozens of stores were damaged.


Loitering Detection
Kids gathering together simply to hang out and do nothing is pretty common; however, these hangouts often turn mischievious where choosing to loiter with friends, rather than attend school, can be a problem. In an effort to deter truancy and disturbing the peace, as well as other crimes such as shoplifting, vandalism, panhandling, and drug dealing, many jurisdictions have specific ordinances to deal with loitering in front of or near public places.

Loitering is a serious problem which can discourage customers from coming into a place of business and lead to harassment and other problems. Cameras that feature Loitering Detection send a mobile alert when the target is in motion inside a defined area longer than a specified amount of time.
