  1. 1. IP Based Closed Circuit Video Monitoring System
  2. 2. CONTENTS  INTRODUCTION TO CCVM  NETWORK COMPONENTS USED IN COMMUNICATION SYSTEMS  MAJOR UNITS OF OLD SYSTEM CCVM  SPECIAL FEATURES OF CCVM  IP CCVM SYSTEMS  IP ADDRESSING MECHANISM  ADVANTAGES AND DISADVANTAGES OF IPCCVM  CCVM VS IPCCVM SYSTEMS  CONCLUSION
  3. 3. What is CCVM?  Closed circuit video monitoring system (CCVM) is the use of video cameras to transmit a signal to a specific, limited set of monitors.  Differs from broadcast television  CCVM is used for surveillance.  Used in hazardous areas that may need monitoring.
  4. 4. Different Network Components Used In Communication Systems. 1) Active Components: Network Switch Media Converter Network Interface Card
  5. 5. Router Hub Basic Block Diagram of Network Containing Router and Hub
  6. 6. 2) Passive Components: Optical Fibre Cable Single Mode Cladding Glass Core Glass Multi Mode Cladding Glass Core Glass
  7. 7. Major Units of Old System CCVM CCD Sensor  Cameras  Lenses  Switching unit  Monitoring unit 
  8. 8. CCD Sensor:The CCD sensors are the device that converts the image captured by a lens into electrical signals which are stored in a camera.
  9. 9. Camera Unit A camera collects reflected images from objects in the environment and then converts them into electronic signals.  Devices involved in the working process: 1) Solid-state imager 2) Monitor 3) Peripherals 4) Signal transmission technology  Camera performance: 1) Sensitivity 2) Resolution 
  10. 10. Lenses It is fixed in front of the camera and is used to focus the required object on the photosensitive plate.
  11. 11. Different Lens Sizes Can Change The Viewing Angle Of A Camera: 3.6mm Lens at 5 Meters(16ft) 12mm Lens at 5 Meters(16 ft) 3.6mm Lens at 15 Meters(65ft) 12mm Lens at 15 Meters(65 ft)
  12. 12. Iris The ability to control a camera’s iris opening plays an important role in image quality. Fixed Iris Manual Iris Auto iris (DC and video) P-iris Cable Types: There are two main types of cables used for transmitting video signals. 1. Unbalanced (co-axial): 2. Balanced (twisted pair):
  13. 13. Switching Unit Camera switchers are devices that allow CCVM system operators to switch between cameras--either manually or automatically. Types of sequential switchers: 1) Bridging Switchers 2)Homing Switchers 3) Looping Switchers 4)Alarming Switchers 5) Combination Switchers 6) Microprocessor-based Matrix Switchers Special Features Of CCVM 1) Frames per second : 2) Pan Tilt Zoom (PTZ): 3) Cameras with special accessories
  14. 14. Existing CCVM System The main parts: 1) Camera Section 2) Cabling 3) Monitor
  15. 15. DISPLAY MONITER
  16. 16. Recording Video Images 1) Tape Video Recorder 2) Digital Video Recorder
  17. 17. Digital CCTV:
  18. 18. IP CCVM SYSTEMS  IP cameras are Closed-circuit Video Monitoring (CCVM) cameras that use Internet Protocol to transmit image data and control signals over a Fast Ethernet link.  Network cameras • Viewing cameras through internet connection. • Communication of data.
  19. 19. Architecture of IP CCVM SYSTEM:
  20. 20. Types of IP Cameras: Types of IP cameras based on internet connection: 1) Wired IP cameras 2) Wireless IP cameras: Types of IP Surveillance Cameras: 1) Fixed 2) Fixed Dome 3) PTZ 4) PTZ Dome.
  21. 21. Process Involved In Working Of IPCCVM
  22. 22. IP Addressing Mechanism An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication. IP Addressing Fundamentals: The two parts of an IP address 192.168.10.10 192.168.10.20.
  23. 23. Subnet Masks: • IP addresses are actually 32-bit binary numbers • Each 32-bit IP address consists of two sub addresses 1) Identifying the network 2) Identifying the host Example: IP address 11000000101010000000000100010100 Subnet mask 11111111111111111111111100000000 IP Versions: IP Version 4 2) IP Version 6 1)
  24. 24. Decomposition of an IPv4 address from dotdecimal notation to its binary value:
  25. 25. Decomposition of an IPv6 address from hexadecimal representation to its binary value:
  26. 26. Potential Advantages: Two-way audio via a single  Higher image resolution:.  Flexibility  Distributed intelligence  Transmission of commands for PTZ (pan, tilt, zoom)  Encryption & authentication  Remote accessibility  Navigation purpose in defence forces.  POE - Power Over Ethernet  On-camera automated alerting via email or file transfer in response to video motion detection or dry-contact alarms.  Password lockout of unauthorized
  27. 27. Facial Recognition Through IPCCVM
  28. 28. IP CCVM at Blast Furnace Blast Furnance Monitor Potential Disadvantages:  Higher initial cost per camera  High network bandwidth requirements  Technical barrier  System becomes open to hacking via internet.
  29. 29. CCVM vs IPCCVM 1) Remote Viewing 2) Remote Recording 3) Wireless Capability 4) Video Analytics
  30. 30. CONCLUSION IP-based technology is the best in terms of security by far. It provides long-term storage. To set-up an IP-based video system is easy -- once in position it starts functioning with extreme stability and reliability. Because this is the technology of the future, it is also upgradeable. CCVM system would not be labeled obsolete because new developments are based on improving this market. IP based CCVM can be said to be a very efficient and reliable method of recording, storing and sharing data with much less fuss as compared to its predecessors Hence a better prospect for the future of data communication.
