1 Video Surveillance Systems: Current Systems and Future Trends Anastasios Dimou Researcher CERTH/ITI
2 Video Surveillance Systems Definition: A video surveillance system monitors the behaviour, activities, or other changing information, usually, of people from a distance by means of electronic equipment. Scope: Prevention Reaction Detection Intervention
3 CCTV Closed Circuit TV CCTV is a system where signals are not publicly distributed but monitored for security purposes.
4 Surveillance in Numbers 16B Global Surveillance Global Market Surveillance (2013, $) 55Bin 2020 Market 14B 0,3B Surveillance Equipment Market (2013, $) 45Bin 2020 Video Analytics Market (2013, $) 1,2Bin ,21B Surveillance Cameras (2013, No)
5 Existing Systems -Analogue An analogue camera transmits video via coaxial cable to a single central location for monitoring, recording, and video analysis. Characteristics: Low initial investment Wide-spread compatibility Robust camera performance under difficult scenarios Hybrid Systems
6 Existing Systems Network (IP) A digital camera transmits video via network to a single central location for monitoring, recording, and video analysis. Characteristics: Superior image quality Easy, future-proof integration Scalability and flexibility Cost-effectiveness Distributed intelligence Remote accessibility Easy, reliable installation
7 Video Analytics Person Vehicle Static objects Object Detection Event Detection Moving in an area Crossing a line Tailgating Loitering Video Summary Thumbnails Target Path Site Map Results Visualization Search Parameters Target type Event type Colour Similar targets
8 Technology Limitations Analogue Systems Low resolution Expensive cabling Bounded scalability Lack of analytics Remote access Hybrid Systems Network Systems Low performance in lowlight environments. Inconsistent frame-rates High cost of cameras Lack of interoperability Network congestion
9 Installation Inefficiencies Surveillance Cameras Poor camera positioning Poor quality video recordings Inadequate maintenance Control room High camera to operator ratio Difficulty in following events across cameras Ineffective operator s workspace setup Communication difficulties
10 Pitfalls and Fallacies (Technology) Network systems are better than Analogue ones More pixels means higher image quality 80% Analytics is Good Enough Analytic systems are in any way a match for an Analytic systems are in any way a match for an (attentive) operator
11 Pitfalls and Fallacies (CSI Edition) Surveillance video quality can be enhanced in a lab using software Facial recognition software can pick someone out of a crowd Most surveillance content is monitored in real time Surveillance videos are stored indefinitely Human behaviour can be predicted
12 Pitfalls and Fallacies (Societal) Video surveillance cameras are an effective standalone crime prevention measure Video surveillance cameras deter crime Dummy cameras may scare away some criminals Surveillance system installations are well targeted The best reaction to crime and security incidents is to put up cameras Video surveillance cameras justify their cost
13 Future Trends in Hardware System-wise Crowd Sourcing Video Surveillance (i.e. mobile devices) Distributed (in edge devices) analytics Migrating physical security onto the network Cameras Wide Dynamic Range (multi-exposure) Super low-light performance Multi-Megapixel cameras Panoramic cameras
14 Future Trends in Software System-wise Video Surveillance as a Service (VSaaS) Integrate applications beyond security (e.g. retail) Social Media Analytics Analytics Face recognition Behavioural analytics Illicit action prediction
15 Emerging Issues Technology Video storage Network utilization Computational needs Video verification Privacy and Security Security in VSaaS systems Privacy issues arising from new analytics Privacy in crowdsourcing solutions
