Supervisor (Mr. Imran Khurram OR Mr. Zeeshan Javed) External Examiner Administrator UIIT III Executive Summary In public places, there is often a need for monitoring people and different activities going on, which can be referred later for many reasons including security. Appointing humans for this task involves many problems such as increased employee hiring, accuracy problem, trust, no proof for later use, and also the fact that a human can remember things till a certain time limit. Talking about the current security system, they use dumb still cameras with a continuous recording facility irrespective of the fact that any event may happen or not. Moreover they are usually pointing at a specific user defined locations so more than one cameras are required to cover the entire region. To prevent all these problems from prevailing, the CSCS is developed. It is a surveillance system, which provides solution to many of these problems. It is a stand-alone application which doesn’t require any computer to operate. It monitors different situations using a camera which is able to rotate intelligently based on sensor messages and captures the scene in the form of video or photos later reference as well. Customizable Surveillance Control System (CSCS) is a surveillance system that can be assigned a sensor type as in our case a heat sensor is used, it works accordingly, rotates the camera upon event detection and perform user defined actions like capturing video and stores them, for the future use. It is an embedded system consisting of Linux fox kit with embedded a running server application also a camera, USB storage device and a sensor node base station is attached with fox kit. LAN communication is used by user to download the videos and to operate the system manually.

Here's how those courses relate to a Laravel-based project: Programming Fundamentals and Object-Oriented Programming: I'll use PHP, which is an object-oriented language, to build my application in Laravel. 2 Understanding programming fundamentals and OOP principles is essential for effective development. Database: Laravel provides an elegant, built-in ORM (Object-Relational Mapping) called Eloquent, which simplifies database operations. My knowledge of databases can be applied to design and work with the database schema effectively. Software Design and Architecture: Laravel follows the MVC (Model-ViewController) architectural pattern. My knowledge of software design principles and architectural patterns will help me structure my application using Laravel's capabilities. Modern Programming Languages: Laravel is a modern PHP framework, so my knowledge of modern programming languages will directly apply to writing clean and efficient code within the framework. Networking: While Laravel doesn't specifically cover networking, my understanding of networking can be useful in cases where I need to work with APIs, integrate external services, or ensure secure data transmission in my application. Human-Computer Interaction: My HCI knowledge will help in designing user-friendly interfaces and ensuring that the user experience of the application is well thought out, which is crucial for the success of an e-commerce application. Introduction to Management: Project management skills are vital for managing the development process, timelines, and resources effectively while using Laravel as the framework. Requirement Engineering: Laravel projects require a clear understanding and documentation of requirements to ensure that the framework is used to build the right features and functionalities. Software Quality Engineering: I can apply testing methodologies, quality assurance techniques, and best practices for code quality within the Laravel framework. Information Security: Security is critical in e-commerce applications. While Laravel provides some built-in security features, my knowledge of information security will help me secure the application against potential threats. Overall, using Laravel for my Multi-vendor E-commerce Mobile Repairing Web Application project leverages the power of a well-established PHP framework. My academic background and courses in software engineering will provide me with a solid foundation to effectively develop and manage my project within the Laravel ecosystem 3 1.2.
