Unmanned Aerial Vehicles (UAVs), commonly known as drones, have revolutionized various industries, ranging from aerial photography and surveillance to package delivery and infrastructure inspection. Their versatility and accessibility have made drones increasingly popular, with a significant rise in their usage worldwide. However, this rapid proliferation of drones has also given rise to concerns regarding their potential misuse for nefarious activities, including cross-border terrorism.
The utilization of drones as tools for criminal or malicious activities poses significant challenges to security agencies and law enforcement. The ability to detect and mitigate such threats is crucial to maintaining public safety, safeguarding critical infrastructure, and ensuring the privacy of individuals. Traditional security measures and surveillance systems may struggle to effectively identify and respond to the presence of drones in real-time, necessitating the development of specialized drone detection systems. This paper presents a comprehensive approach for drone detection through closed-circuit television (CCTV) systems, leveraging advancements in image processing, deep learning, and computer vision techniques. The objective is to develop a reliable and efficient system capable of detecting and alerting security personnel to the presence of unauthorized drones in sensitive areas.
The proposed drone detection system harnesses the power of deep learning, specifically convolutional neural networks (CNNs), to analyze CCTV footage and identify drones with high accuracy. By training the model on diverse datasets containing images and video footage of different drone types, the system learns to distinguish drones from other objects in the surveillance imagery.
Integration of various frameworks, including OpenCV, NumPy, TensorFlow, MATLAB, and Qt5, enhances the detection process, enabling efficient preprocessing, feature extraction, and real-time monitoring. The system architecture encompasses data collection, preprocessing, and the application of deep learning models to detect drones accurately.

This section presents the methodology employed in the drone detection project using CCTV. The approach consists of several stages, including data collection, preprocessing, feature extraction, classification, and alert generation. Additionally, the utilization of the Zoo model for image processing is described.
A. Data Collection
In this project, data collection involved the acquisition of CCTV video footage from various surveillance cameras. The videos were captured in different environments and conditions to ensure a diverse dataset for training and evaluation purposes. The collected data included instances of both drone presence and non-drone scenarios to enable accurate classification.
The collected video frames underwent preprocessing techniques to enhance their quality and remove any noise or artifacts that could affect the subsequent analysis. Techniques such as resizing, noise reduction, and image enhancement were applied to improve the clarity and suitability of the frames for feature extraction.
C. Feature Extraction
Feature extraction is a crucial step in identifying drones from CCTV footage. In this project, various techniques were employed to extract discriminative features from the preprocessed frames. These techniques encompassed shape descriptors, texture features, and motion characteristics, which collectively provided valuable information for differentiating drones from other objects in the scene.
The extracted features were utilized to train a classification model capable of distinguishing between drone and non-drone instances. Machine learning algorithms, such as Support Vector Machines (SVM) or Random Forests, were employed to train the model using the labeled dataset. The trained model could then predict the presence of drones with high accuracy.
E. Zoo Model for Image Processing
As part of the methodology, the project incorporated the use of the Zoo model for image processing. The Zoo model is a collection of pre-trained deep learning models available in popular frameworks like TensorFlow and PyTorch. These models, trained on extensive datasets, provide a starting point for various computer vision tasks, including object detection and classification. By leveraging the Zoo model, the project benefited from the expertise and accuracy already achieved in the field of image processing.
F. Alert Generation
Once a drone was detected through the classification process, an alert was generated to notify the relevant authorities or security personnel. The alert system integrated with existing communication channels, enabling timely responses to potential security threats posed by drones.
By following this methodology, the drone detection project utilized data collection, preprocessing, feature extraction, classification, and alert generation techniques. Additionally, the inclusion of the Zoo model for image processing enhanced the accuracy and efficiency of the detection system.

A high precision score suggests that the system can effectively minimize false positives, reducing unnecessary alarms or alerts. A high recall value indicates that the system can detect drones without missing any instances, minimizing false negatives.
The false positive rate is an essential metric to evaluate the system's ability to differentiate between drones and non-drones accurately. A low false positive rate ensures that the system does not generate excessive false alarms or misclassify harmless objects as drones. Additionally, the processing speed is crucial for real-time applications, where the system needs to analyze CCTV video streams swiftly to provide timely detection results.
