ASK QUESTIONS!!! This stuff isn’t Rocket Science, but it isn’t simple either. Please let me know what I can do to ensure you leave with a better

understanding of the topic than you arrived with!

What does “Analytics” mean?

Merriam Webster Dictionary = “The method of logical analysis”

Gartner = "Analytics leverage data in a particular functional process (or application) to enable context-specific insight that is actionable.“

Me = The use of algorithms that enable software to detect situations significant enough to require human attention.

Basics of Video AnalyticsVideo Analytics: The use of computer automation to process video to classify

people, vehicle, objects and analyze patterns of behavior Video analytics provide structure to unstructured video Structure makes video actionableThe case for Video Analytics: The human brain can process a static image virtually

instantaneously However, faced with 30 images a second of high resolution

images filled with small profile objects, the brain fatigues

Basic Mall Environment – How much can you actually pay attention to?

How many screens can you actually watch? Increasing camera count reaches a point of

diminishing return 99% of video is never seen. Cameras are not

displayed in real-time and video archives are too large to search effectively

During crisis situations large numbers of cameras complicate situational awareness

Alert 101 Video Analytics – Discussing Reality

Updates on the Video

Many of the issues mentioned in the video have already been resolved.

These capabilities are improving all the time

Megapixels Do Matter…

Video Analytics are dependent on the cameras providing their feed. Make sure your cameras are providing sufficient quality to enable the analytics you are hoping to achieve.

The Camera can see more than Humans can process

640px X 480pxVGA Camera coverage

2592px X 1944px5 MP Camera coverage

6576px X 4384px29 MP Camera coverage

Analytics – The Key to Increasing EffectivenessVideo analytics software can process video in different ways:

1. Real-Time Detections and AlertsDefining events and scenarios and receiving real-time alerts when such events are detected

2. Video SearchSearching through recorded video after an incident to pinpoint specific video footage

3. Business Intelligence Analyzing video footage and generating statistical reports from the data collected within the video

Video Analytics – Criteria to Consider

Objects in Area Object Loitering Objects Crossing Beam Object Appears or Enters

Area Object Not Present in Area Objects Enter Area Objects Leave Area Object Stops in Area Direction Violated Tamper Detection

Good Use Cases for Video Analytics Security Around Critical Zones

Increasing awareness (1. display cameras in critical zones only when people or groups of a certain size are present. 2. detect objects left behind.)

Incident investigation (1. search for people or vehicles based on size, color, areas entered, loitering etc. )

Situational awareness during Crisis response (1. with predefined searches, instantly display thumbnails of all people entering or leaving the facility or an area of the facility.)

Property protection (detect objects removed from defined areas.)

Value Proposition Behind Use Cases Security Around Critical Zones

Increasing awareness ▪ Cost advantage: reduced asset loss, reduced corporate liability, improved citizen safety

Incident investigation ▪ Cost advantage: direct reduction in labor and overtime from investigations

Situational awareness during Crisis response ▪ Cost advantage: Improved officer and citizen safety

Property protection ▪ Cost advantage: reduced asset loss

Analytics – Horsepower in Your Cameras

Video analytics instantly detects and learns the monitored scene upon installation, adapting to changes and movement patterns without complex manual calibration. • In the Camera

• Rules Based• Self-learning

Benefits of Video Analytics Less human eyes required = Personnel cost saving Humans not staring at screens, waiting for

something to happen = Reduction in personnel burn-out Improved awareness of specific events = Improved safety or security Automated identification of trends or changes to

typical situations = Advance warning of potential issues

Basics of Audio Analytics

Sound based rather than the visual of Video Analytics

Can be stand-alone, like ShotSpotter, or tied into a Video Surveillance System

Can be designed for various sound types

Audio Analytics ShotSpotter The best known Audio Application on the market

today is ShotSpotter

ShotSpotter Pros & Cons

ShotSpotter is an excellent tool for capturing specific shooting location information

Unless officers arrive very quickly the shooter could be long gone before they arrive, making arrests and convictions harder to achieve

Main Audio Analytics Types

Aggression Detection Gunshot Detection Glass Break Detection Car Alarm Detection

Aggression Detection Description: 90% of physical aggression are preceded by verbal

aggression, the aggression analytics product allows security guards for fast actions. This aggression detector is capable of recognizing aggression in a person’s voice. Staff can thus be warned at an early stage, if someone is beginning to show signs of aggression. The system automatically and objectively detects (rising) human aggression, anger or fear, warns staff immediately (by a visual alert or by triggering an alarm) so that physical aggression can be prevented. It makes the problem of aggression measurable (reports).

Benefits and Features of Aggression Detection Benefits: Early Detection to prevent escalation and/or physical Privacy and confidentiality: Does not listen to language or words but tone and pitch (works like

a human ear)

What does it listen for? Human aggression, anger, shouting.

Applications: Commercial Setting, Retail, C-Stores, Public Spaces, Mass Transit,

Hospital rooms, and Interrogation Rooms

Gunshot Detection

The Gunshot Detector recognizes firearm discharge in different settings. Within seconds of a gunshot, the software accurately classifies and triggers an immediate notification through VMS or other source. Security staff can then verify alarm and reduce the response time of personnel. This analytic can successfully detect most firearms including handguns, shotguns, rifles and automatic rifles.

Benefits and Features of Gunshot Detection

Detection Range: Up to 3,000 Ft. = Quiet Environments 1,500 Ft. = Normal Environments 300 Ft. = Noisy Environments What does it listen for? Gun discharge from most commonly used guns, does not work

with weapons with a silencer. Applications: Education- school and university campuses Commercial- Retail,

Banks, Shopping centers - 70% of incidents occur in either Education or Commercial settings Public Spaces, City Streets

Glass Break Detection

Product Description: The Glass Break Detector software easily

integrates into existing video surveillance systems and VMS, eliminating additional devices or their installation cost associated. The detector is designed to classify the breakage of today’s most commonly used glass including laminated, single or double plate, tempered and wired glass. The Glass Break Detector works by analyzing both the initial impact sound followed by the sound of glass shatter.

Benefits and Features of Glass Break Detection Applications: Car Dealerships – not cars Car Dealership Building- Yes Parking Garages – no

Commercial Buildings, Retail, Hospital, Banks What does it listen for? Listens for a combination of the impact sound and the glass shattering. Why is this better than motion detectors? With motion detectors, the intruder is already inside. With glass break

detection, an alarm siren can be played to prevent the intruder to go inside. Detection Range: Up to 100 Ft. = Quiet Environments 50 Ft. = Normal Environments 25 Ft. =

Noisy Environments

Car Alarm Detection

The Car Alarm Detector accurately classifies the specific sound pattern produced in today’s most common car alarms systems. The software can detect specific repetitive sound patterns of car alarms up to 300 feet away, making it ideal for any location with many cars such as a parking garage or car dealership. The detector allows security staff to deter or improve reaction time to incidents in real time.

Benefits and Features of Car Alarm Detection

Detection Range: Up to 300 Ft. = Quiet Environments 150 Ft. = Normal Environments 60 Ft. = Noisy Environments Applications: Parking garages (Shopping malls, offices, hospital) Transportation

hubs Airports Car dealership What does it listen for? Looping progression of specific tone patterns

Take Away Points!

Video and Audio Analytics are powerful tools for the Law Enforcement and Security professions!

The enhancement of Video Surveillance from the addition of Video and Audio Analytics should provide improved results of at least an order of magnitude!

Design of such systems can be difficult, but the potential results are worth the effort!
