1. . INTRODUCTION :With the acceleration of higher education institution construction, the campus area is gradually expanding, as is the total amount of mobile employees. Various erratic elements have also posed major obstacles to campus safety management. Video surveillance is an essential instrument for keeping the campus safe. However, there are still many analog and digital hybrid systems used in college and university video surveillance systems that can no longer meet the requirements of the development and construction of new digital campuses and smart campuses.

   The video surveillance system has a long history of development as an important security method, and it has been widely employed in the fields of public safety monitoring, manufacturing process monitoring, and so on. monitoring, as well as monitoring of residential communities.With the advancement of multimedia technology and the progressive development in people's quality expectations of life, video surveillance system research has received tremendous attention. On the one hand, picture development

III. EXISTING METHODOLOGIES 1.SURVEILLANCE VIDEO SYSTEM

The video surveillance system can carry out a wide range of advanced and powerful activities. The inbuilt video processing module front end examines the monitored image and employs clever algorithms to compare to user-enhanced security model. When a security danger becomes apparent, surveillance begins.The center is swiftly notified. The robust image processing the video processing module's capacity and the robustness Algorithms with intelligence can significantly increase the accuracy of alarm and limit the likelihood of false positives and false negatives negatives. The specifications for video surveillance systems The price tag of video processing modules is very costly as well. It not only has to be finish the video encoding and decoding processes, but also allows for real-time processing of intelligent video so that the system can recognize the algorithm

Tracking optimization algorithm performs weighted data merging based on priority of target and its occlusion state in each camera and the size of the segmented image, assigning high priority Target the camera with the best weight for tracking and Automatic load balancing monitoring, assigning low priority The target in the camera has a large tracking load on others cameras for monitoring.

IOT : IoT refers to a loosely coupled system of multiple heterogeneous and homogeneous devices which can sense, process and network.

1. RESULTS AND DISCUSSION :

   Due to the large differences in structure of different individuals After GA optimization, the detection accuracy of Individual fluctuations are within a small range. So in experiment, we integrate the results after 10 GA optimizations for reference.To reflect improvements in accuracy and durability GA brings the BN- based system in the process optimizer,Figure 13 shows the initial model based on expert knowledge (IMEK notes) and models after GA optimization (recorded to GAOB). We can see that in the worst case scenario, GAOB can still maintain a DR close to 95%.IMEK drops rapidly to about 81%. It means The model after GA optimization has higher robustness and detection accuracy, thanks to GA optimization structure and parameters of the model accordingly and correct areas of incomplete professional knowledge and meet the requirements of smart campus construction.The quality of surveillance video is mainly reflected in performance indexes such as real-time, fluency and clarity.

This article first optimizes the quality of internal monitoring video surveillance system, effectively improve quality of video surveillance and ensures real-time, efficient,and high- definition surveillance video. Monday,for large- scale distributed video surveillance system, one tracking optimization method based on multi- camera fusion proposed to achieve effective combination of goal coherence between multiple cameras. Finally, this article elaborates a Bayesian approach to modeling surveillance- based events genetic algorithm, can reduce the

redundancy of the system, Reduce optimization complexity, increase system modeling flexible and reduces the amount of data needed for optimization.Simulation experiments show the optimal model Video surveillance system can effectively implement cooperation Monitor multiple cameras in wide area surveillance scene, achieving high tracking and monitoring performance, and meet the requirements of smart campus construction.
