Comprehensive Analysis of Video Surveillance System and Applications
Nand Kishore Sharma1,*,Surendra Rahamatkar1,Abhishek Singh Rathore2Abstract
In this growing age of technology, various sensors are used to capture data from their nearby environments. The captured data is multimedia in nature. For example, CCTV cameras are used in those places where security matters or where continuous monitoring is required. Hence object detection, object recognition, and face recognition became key elements of city surveillance applications. Manual surveillance seems time-consuming and requires huge space to store the data; hence video surveillance has a significant contribution to unstructured big data. All surveillance techniques and approaches are based on Object Tracking, Target Tracking, Object Recognition, and Object Mobile Tracking Systems (OMTS). The main difficulty, however, lies in effectively processing them in real time. Therefore, finding a solution still needs careful consideration. This paper mainly targeting to the smart city surveillance system and inspects all existing surveillance systems based on various tremendous technologies like a wireless sensor network, machine learning, and Deep Learning. The author discovered the problems in the existing methods and summarized them in the paper. The motive is to point out the various challenges and offer new research prospects for the multimedia-oriented surveillance system over the traditional surveillance system for the smart city network architecture. The thorough survey in this paper starts with object recognition and goes toward action recognition, image annotation, and scene understanding. This comprehensive survey summarizes the comparative analysis of algorithms, models, and datasets in addition to targeting the methodologies.
INTRODUCTION
Surveillance may be outlined in a variety of ways, including vehicle monitoring at roadside traffic areas as an intelligent traffic management system, theft monitoring & identification, capturing abnormal happenings, monitoring of widely open critical areas, and crowd analysis. Apart from that, it is also important in the smart healthcare system to perform hospital surveillance, secure hospital facilities, detect patient emotion and sentiment, detect patient fraud, and analyze hospital traffic patterns.
The video surveillance system has progressed. Now it is not only aiming to capture and show the video but has upgraded towards an autonomous and intelligent system. Only cutting-edge algorithms have made this possible. Because the purpose of all these algorithms was not only to classify images or videos but also to enhance them. Thus, a modern surveillance system workflow is mentioned in Fig. (1). As a result, video surveillance makes a significant contribution to unstructured big data.
Fig. (1)) Surveillance System workflow.Intelligent surveillance is the main application of a Smart city, and the objective of the Smart city is to improve the quality of human lives. Smart environments contain sensors & devices that are network-connected and work together to perform operations. Though the last decade, the Internet of Things (IoT) with Machine Learning & Deep Learning has received so much attention. The cause for the accomplishment of this much attention is the services and capabilities offered by it.
The IoT is an interconnection between everyday objects and computing machines. It enables them to communicate in many smart city applications, where smart surveillance is one of them. Intelligent Transport Management Systems, Intelligent Traffic Management systems, Vehicular Ad-Hoc Networks, and Car-to-Car Communication are a few examples of IoT. Here, Intelligence indicates the best utilization of data. This data is generated by aggregating the knowledge and then converted into information through modeling. After that, this information is used for further processing.
In reality, all of this generated data is also known as multimedia data, such as audio and video. Their combination also makes the computation more energy efficient. Wireless Multimedia Sensors are used to collect multimedia data. However, Wireless Multimedia Sensors have exceptional issues such as high bandwidth and energy consumption. Other issues observed include quality of service (QoS), data processing, and compression at the node level. Object detection and recognition schemes have emerged in recent years as a solution for reducing the size of multimedia data at the node level.
The strategy used in it is based on motion detection. The camera only starts recording when it detects motion; otherwise, it does not record. As a result, unnecessary recording and storage are avoided. As a result, no overhead exists.
However, it is inefficient in some ways because it requires the user’s involvement to process forwarded data, so that alert decisions can be made. A simple object classification with few details can work. It is based on a genetic algorithm-based classifier. The classifier used only two features of the objects:
1. Video frames: specifically, the shape of the minimum bounding box, also known as video annotation of the object.
2. The frame rate of the observed region.
This method was tested in a simulated environment on three types of objects: humans, animals, and vehicles. The observation was that as the audio was added, the noise count increased [1].
The evolution of IoT presents enormous challenges in data collection, data analysis, and distribution in the direction of more productive use of information [2].
According to the survey, video surveillance systems have advanced technically over three generations.
The survey said that the video surveillance systems have technically progressed as:
The first generation was introduced in the 1960s with Analogue Close Circuit TV (CCTV). That was primarily for indoor surveillance applications. But the limitations were the recording and distribution process.Digital imaging began to expand surveillance systems in the 1980s. Advances in this area include compression and distribution as well as surveillance algorithms. The system included object tracking as well as an event alert system.The third-generation surveillance systems with fully automated and wide-area surveillance were investigated in the 2000s. The goal was to provide inference frameworks and behavioral analysis.There are several categorizations of video surveillance that can be drawn to fulfill the requirement. Systems are usually classified into three generations as shown in Fig. (2). And the below Table 1 is representing the same categorization.

Low-cost, compact cameras and microphones are now being introduced by recent technological advancements. And research started to get more precise real-world information. The outcome was distributed Wireless Multimedia Sensor Network. Multimedia sensors make it simpler to gather more accurate and thorough data for a variety of smart city applications. A multilayer automatic surveillance system architecture is suggested in a study [3] for outdoor applications. The system has two layers at the node level. Scalar sensors having the ability to sense motion, vibration, and sound are present in the first layer. This layer activates the second layer to record audio and video. Scalar and multimedia sensors gather data, which is then analyzed and combined in three separate layers.
In computer vision and robotics, automatic human action recognition in any video stream has been a highly addressed challenge. Majorly works were focused on classifying the segmented clips, joint detection, and action recognition. But none of them were dealing with wireless camera networks. To deal with this issue [4], an efficient system is presented by using a wireless smart camera network. The approach was based on Deformable Part Models (DPMs) for object detection in the images. Later, the framework was extended with tight integration inside a centralized video analysis system named Deformable Keyframe Model (DKM) from single-view and multi-view video settings to joint detection and action recognition. The DKM was validated on two different datasets- the publicly available dataset, and Bosch Multiview Complex Action (BMCA) dataset.
In a study [5], a deep learning technique was introduced to predict the type of action in smart cities. Four different types of audio datasets were used: crowded city audio, home appliance sound, household item sound, and human action sound.
The analysis of video surveillance was covered in a study [6]. The study classifies it into two categories, abnormal and normal, as well as object and action recognition. Deep learning architectures is the main topic of this survey. CNN, auto-encoders, and their combinations are the most often used deep learning models for surveillance analysis.
The video data is increasing because of the many networked cameras located in public places around the world for security [7
