2. NoxEye: An AI based threat detector for
Intelligence Surveillance and Alert System

3. Objective
• The main objective of this project is to provide crime detection and
proactive alerts using edge-and fog-integrated approaches.
• To provide intelligent applications with AI.
• Provides an alert by sending the crime data instantly to the police or
protective service, and thus, it ensures a quick response.

4. Abstract
• Nowadays, theft has become a major issue to be dealt with.
• It is not possible for a human to monitor for several hours continuously.
• To overcome the complication in thefts, surveillance cameras are used.
• The main ability of surveillance camera is to just record the act of theft from
which only the knowledge of the intruders will be gained.
• This project presents NoxEye, a lightweight AI-powered threat detector for
intelligent surveillance cameras, which can be deployed on-site at the edge.

5. Existing System
• Framing and Blob recognition (FBD) for Input video preparing and (HON)
Human tracking.
• HOG is in charge of pulling back shape data of question in picture utilizing
force angles and edge headings.
• General purpose computing on graphics processing units (GPGPU) that is
appropriate for use in human stance estimation, and accomplishes constant
execution. A diminishing calculation iteratively expels limit voxels from a
question create a topologically identical skeleton.

6. • K-nearest neighbor is a strategy for grouping objects in view of
nearest preparing cases in the component space.
• Scale Invariant Feature Transform (SIFT) has been turned out to be the
most powerful nearby invariant element descriptor.
• SVM kernel functions based classifiers to distinguish the malicious
nodes from benign ones via evaluating the variance in their Driving
Pattern Matrices (DPMs).

7. Disadvantages
• The project or system was unable to detect motion in case of moving
camera.
• The risk of outliers and ghost points, reduces the performance of the
motion detection system.
• Target harden to find
• Reduce provocation
• IoT-cloud architecture has issues regarding bandwidth, energy, and
latency in real-time video surveillance applications.
• Delayed multimedia IoT tasks.

8. Proposed System
• This paper presented the design and implementation of Nox-Eye, an
AI-enabled threat detector for realtime video surveillance.
• With the help of AI, each fog node can detect and identify a possible
crime event and crime object by processing the motion-captured
images sent by an edge node.
• FRCNN model running at a fog node detects and labels the images
with the name of the crime objects having the highest probability, and
saves those images.

9. Advantages
• The proposed system is far more efficient even without the video
compression algorithm.
• Proved the superiority of our proposed system in terms of agility,
scalability, energy, and CPU and memory usage.
• Efficient crime predictive system
• Real-time crime event detection, ensuring resource efficiency and
good distribution of the processing load in an IoT-based video
surveillance system.
