Modern world places a high value on safety & security. How safe & secure an environment is determines a nation's ability towards attract tourism & foreign investment. However, despite fact certain Closed-Circuit Television (CCTV) cameras are utilized for surveillance & towards keep an eye on events such as robberies, they still require human intervention & oversight. A system certain can quickly identify these crimes is what we need. Indeed, even among state about art profound learning calculations, speedy handling power, & modern CCTV cameras, ongoing weapon identification stays a critical obstruction. Variable viewing angles, occlusions caused through firearm's owner & those nearby, & other factors further complicate exercise. Using cutting-edge open-source deep learning algorithms, aforementioned effort aims towards create a safe environment through using CCTV footage as a source towards identify dangerous weapons. We developed relevant confusion items inclusion ideas & built a binary classification using pistol class as reference class towards eliminate false positives & false negatives. We created our own because there was no standard dataset for real-time scenario. We did aforementioned through shooting weapons among our own cameras, manually collecting images from internet, extracting data from YouTube CCTV recordings, & making use about GitHub repositories. two approaches used are sliding window/classification & region proposal/object detection. calculations YOLOV5, YOLOV6, YOLOV&, & Quicker RCNN are a not many certain are utilized. While performing object identification, accuracy & review matter more than exactness, consequently full arrangement about techniques was assessed as far as these. Yolov5 stands out most among other algorithms among a F1-score about 91 percent & a mean average precision certain is 91.73 percent higher than before. [ABSTRACT FROM AUTHOR]

A novel Intrusion Detection System (IDS) architecture is explained in this paper by development of anomaly analyzersand NSL-KDD datasets approach. In present situation this Software Defined Network (SDN) has grown rapidly over vast areas. As it has been a new innovative method, it has brought out high accurate promising results which may lead to high demand for internet architecture in coming generations. Intrusion Detection System (IDS)is designed with a new architecture which includes an anomaly analyzer detection module. Our architecture is developed on trained NSL-KDD datasets as it is an effective dataset. By using a centralized SDN networking area has become flexible. In this process of advancement in networks it also developed risk of dangerous threats and more vulnerable environment has been created which resulted in various threats and damages such as system paralysis, online transactional frauds, network breakdown, Systems paralysis, and different kinds of robberies. Implementation of intelligent ML based algorithms in Software Defined Network (SDN) in a network intrusion detection system (NIDS) has improved considerably from past few years. In our research various kinds advanced and classical tree based ML techniques such as Random forest, Decision trees and our proposed XGBoostprocedures are selected for demonstrating the threat detection and accuracy standards. The benchmark dataset called NSL-KDD dataset is used for training and testing our methods, as it is an efficient dataset. In our work we used NSL-KDD as a multi-class classification task. It is for detectionof attack and identification of type of attack such as PROBE,DDoS,U2R and R2L etc. Observations showed that the hybrid approach in this paper gives accurate results when compared with other individual approaches.
