What are the requirements of workplace surveillance?

The basic requirements of Workplace surveillance is classified in 2 categories.

Technical Requirements

1. Python 3.5 or above
2. dlib==19.21.1
3. face-recognition==1.3.0
4. face-recognition-models==0.3.0

Other Requirements

• CCTV cameras access
• Required Employees Data (front, left, and right side of the face)
• CPU-based implementation is very slow. We need a GPU to implement the above scenarios on the CCTV feed.
• Connectivity to Database

Why is a Video Surveillance Dashboard necessary?

• Identification: 

• Paperwork: 

• No Anomaly Detection:

• No Historical Tracking: 

Video Surveillance Solutions for Businesses

As per the scenarios we are covering, there are two phases to be covered in this solution:

Phase 1: Identification

1. Authorized
2. Unauthorized
3. Temporary Access granted

1. Anomaly Detection(Live Tracking)
2. Prohibited Area
3. Access Control
4. Exit
5. Map Person

Video Surveillance Solution Phase 1 for Business Case Identification

The solution’s main objective is to develop a model that identifies and classifies the person as authorized and Unauthorised.

Implementation of the solution

• The architecture of the solution
• Steps of the solution

The workflow of the solution is given below in the steps.

Step 1: We should have the images data of authorized persons in this folder

Data →RealTimeImages →Encoding Images →(authorized person images)

Step 2: Detection of faces and recognition of the person’s identity by matching the faces from authorized persons’ saved database. If the person is authorized, it will show a green colour rectangular bounding box around the face of an authorized person; if the person is not permitted, it will show a red colour rectangular bounding box around an unauthorised person.

Step 3: Suppose the person recognises it as unauthorised, then will collect the data of a person.

Step 4: Allocate time-based to enter the building; when the time exceeds, the alert will be sent to the person and authority and track the user if the extra allocated time is still exceeding.

• Output of the solution

From the above approach, we’ll get the following outputs:

Note: The model will generate these columns as output, decided as per the requirement of the AnalyticsOps Team

Usability of Solution

The figure shows how we can use the Identification Feature for Authorisation and
Un-authorization

Phase 2 Solution: Behaviour Analysis and Exit

1. This phase of the solution’s main objective is to develop a module that can handle Behaviour Analysis and Exit parts.
2. The Camera will map the exit of a user by providing the exit time of the user.

• Implementation of the solution

Step1: Architecture/Steps of the Solution

Step2: Usability of the Solution

Step3: Output of the model

Prohibited Area, Unique_User_ID, Authorized, Unauthorised, Severity, Date, Time, Area, Area wise Duration, Unique_User_ID, Unauthorised(Y/N), Name, Area, Duration, Purpose, date, Entry time, Exit time

Note: The model will generate these columns as output, decided as per the requirement of the AnalyticsOps Team

Investigation of Video Surveillance

One of the organizations’ significant challenges is to identify, track and detect those anomalies and persons. Some other challenges of workplace surveillance are :

1. Identification: Organizations are not able to identify known or unknown people as a lot of people visit the workplace.
2. Paperwork: Need a lot of paperwork to handle their entry record. Manual processes are not only inefficient but also increase security risk and costs.
3. No Anomaly Detection: Organizations are not able to detect any anomaly at workplaces.
4. No Historical Tracking: Organizations are not able to track or map if a person is visiting again and again.

Incident Response

How can XenonStack Help?

Boundary Breach Detection

• Virtual Boundary: It allows for tracking the entry and exit of people in a particular area. Thus, users can track the number of visitors, their time of visits, and the duration of their stay there. It allows interlopers to access those areas.
• Forbidden Area Violation: The system generates an alert a person doesn’t have access to a certain area but enters there. It detects real-time violations and malicious activities, thus enhancing the safety and security of the place.

Theft Analysis

• Theft Alert: Systems always track the inventory of a workplace. If it detects any object's movement at an abnormal time, it alerts the manager.
• Loitering: The system keeps track of passers-by and records the time they spend in monitored zones. The system generates an alert when more than usual time is spent by a passerby at the same spot.

Anomaly Detection

• Suspicious Movement Analysis: If anyone spends extra time in a specific location, the system will raise the alarm. Thus detect any suspicious activity before it occurs on-premises.
• Abandoned Object: The system can identify unattended stationary objects, thus detecting threats of cases where objects are left behind with wrong.
• Fire Alert: CCTVs or smoke detectors only detect smoke or fire. But they respond only to smoke or flames after the fire has already begun.

Density/Flow

• Bottleneck Analysis: The system may detect a crowded place immediately and alert the organizer. For taking immediate action to make the environment peaceful by reducing the wait time.
• Entry/Exit Counts: Using a feature-rich camera placed at different locations, users can keep track of the persons and an object entering or exiting the premises.
• Traffic Queueing: The system detects the traffic of people and vehicles at entry gates. And monitor their behavior and early detect the situation before it becomes more cumbersome.

Trip Tracking

• Path Analysis within an Area: The system keeps track of the visitor’s journey to monitor their activity always.
• Presence Distribution Map: Analysing the location and people density in various locations a different times. Users can make decisions regarding scheduling the break and the work timing of people.

Questions to Discuss for Video Surveillance

• How does the system prevent the entry of unknown people? How does it get to know that a person is unknown?

• Okay, I got to know how the system will detect and prevent the entry of unknown people. But what if a visitor or interviewee comes for the first time? How does the system allow them to come? How does that person get an entry? Whether he/she will be able to come inside the workplace or not?

• As answered in the previous question, that system will give access to them. What is necessary to give access?

• How does the system get to know that the access they were given to is the right person? Because it may be possible that the person is not coming for an interview, he can be the wrong person?

• Okay, As discussed in the previous question, a person will be allowed entry for some defined time. How will the system get to know whether a person leaves at the correct time or not?

• It is also possible that the person that entered the workplace went to the wrong location by mistake or intentionally. Or it may also be possible that person is harming another person or ruining infrastructure. How may the system get to know about that?

• Are these all cases possible for authorized because he/she may also do the same?

• A person may be visiting again and again, but he/she is not a regular person, so he/she has to register themselves? How did the system get to know?

• When does the system stop tracking?
