Title: Intelligent surveillance camera control and notification system

Description:
TECHNICAL FIELD 
     The present disclosure relates to an intelligent surveillance system. More particularly, the present disclosure relates to an Intelligent Surveillance Camera Control and Notification System. 
     BACKGROUND 
     It is necessary to work on various security methods because of the increase in crime rates that can be attributed to the total populace and joblessness proportion. 
     The traditional policing approach focuses on responding to incidents such as theft, robbery, and assault by conducting investigations. However, these responsive efforts are not sufficient to prevent violent incidents from occurring. In the modem era, technology has become an integral part of public and personal safety. 
     In a prior art, a system is proposed that controls a network of surveillance cameras based on user-defined rules. The system can be configured to detect specific events, such as a person entering a restricted area, and can trigger an alert or take other predetermined actions in response. 
     In another prior art, a system is proposed that automatically pan and tilt a surveillance camera to track a moving object. The system uses image recognition algorithms to identify the object and then moves the camera to keep it in view. 
     In another prior art, a system is proposed that integrates surveillance cameras with other sensors, such as motion detectors and door sensors, to provide a more comprehensive view of a monitored area. The system can be configured to send alerts or take other actions based on the inputs from the various sensors. 
     Closed circuit television (CCTV) camera-based surveillance and control systems are used to monitor incidents worldwide. However, identifying events requires human personnel. This human-based continuous monitoring in surveillance camera systems is error-prone because it is not humanly possible to constantly monitor the surveillance area minutely. Although human intervention can identify unusual activities, they can make mistakes while monitoring for a long time. Without automated surveillance, there is a high likelihood that the system can make mistakes in detection. To reduce the errors, the surveillance system should be automated. Thus there is a need of an automated system for camera surveillance. 
     In the view of the foregoing discussion, it is clearly portrayed that there is a need of an Intelligent Surveillance Camera Control and Notification System. 
     BRIEF SUMMARY 
     The present disclosure relates to an Intelligent Surveillance Camera Control and Notification System. The proposed system is a framework for weapon detection for public safety and security, wherein this system helps in proactive safety efforts. This present disclosure manages the planning and execution of an intelligent observation checking framework utilizing a Raspberry Pi and a PIR sensor for cell phones. It broadens the use of versatile innovation to provide fundamental home security and other control applications. The proposed home security framework collects data and transmits it to a PDA via a 3G Dongle via a web application. Raspberry Pi operates and controls movement finders and camcorders for remote detection and reconnaissance, as well as transfers live video and records it for later playback. With the help of the infrared sensor, it can also determine the number of people present. For example, when movement is detected, the cameras begin recording, and the Raspberry Pi device alerts the owner of the potential interruption using a PDA. Raspberry - Pi has two main parts that communicate with one another: the Internet Application, which runs on the phone’s program, and server - side scripts, which create a cloud that will be worked by the Raspberry Pi Equipment instrument part. As a result, we devised a clever reconnaissance framework capable of recording/capturing video/pictures and transmitting them to a PDA. It is advantageous because it provides dependability and security on both sides. It is validated and encoded on the receiver side, so it only allows the individual concerned to see the nuances. Necessary moves can be made in limited capacity to focus time on account of crisis conditions, for example, older individuals falling ill, military regions, savvy homes, workplaces, ventures, and so on. Future work is to find the number of people found precisely on that region and their position so precise data can be obtained on the recipient side.

     In an embodiment, the one or more camcorders from the plurality of camcorders that turn towards the moving object are the camcorders that are focused towards the moving object or within the range of its focus. 
     In an embodiment, an Intelligent Surveillance Camera Control and Notification System also comprise a web-based user interface for receiving the real-time video/image of the moving object remotely via the communicating device. 
     In an embodiment, the object is selected from a person, a vehicle, a drone, or anything that is seen by the naked eye. 
     An objective of the present disclosure is to provide an Intelligent Surveillance Camera Control and Notification System.

       FIG.  1    illustrates real-time weapon detection in surveillance CCTV system by using a hybrid approach in accordance with an embodiment of the present disclosure. It can be seen from the figure that the proposed framework works in four significant stages namely, (a)Collection stage for informational collection age for preparing, (b) preparation stage for preparing of the item recognition models, (c) test stage for testing of the proactive observation CCTV framework, and (d) and implementation stage for sending the model for ongoing reconnaissance. 
     The interaction begins with the socialization of a weapons dataset, which is then used to prepare the deep learning models. The prepared models are tested for crossover blend, and the model is then used progressively observation. The step by step working of the proposed framework is mentioned below.
     1. Initially, the YoloV4 strategy divides the image into districts. The image is divided into a few frameworks, also known as remaining blocks. Every matrix is S x S in size, and each network cell’s articles will be distinguished independently.   2. The Consequences be damned model purposes relapse with a single jumping box to conjecture the items’ class, width, level, and focus. As a result, it envisions a constrained edge box with probability for each district. Simultaneously, it computes the probabilities of various restricted edge boxes and their classes.   3. The convergence over association, or IoU, is a concept in item recognition that depicts how the containers are covering. The IOU creates a result box to precisely encompass the things in Just go for it. Every matrix cell evaluates the bouncing boxes and their certainty scores.   

     If the normal and real bouncing boxes are comparable, the IOU is assigned a value of 1. This method eliminates jumping encloses that aren’t the same size as the genuine box. The most recent discovery consists of exceptional jumping confines tailored to the items in question. 
     In an embodiment, the Yolo results are mentioned in the table given below.
