- 8. CCD Sensor:The CCDsensors are the device that converts the image captured by a lens into electrical signals which are stored in a camera.
- 10. Camera Unit A cameracollects 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
- 11. Lenses It is fixedin front of the camera and is used to focus the required object on the photosensitive plate.
- 12. Different Lens SizesCan 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)
- 13. Iris The ability tocontrol 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):
- 14. Switching Unit Camera switchersare 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

- 24. IP Addressing Mechanism AnInternet 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.
- 25. Subnet Masks: • IPaddresses 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)

- 28. Potential Advantages: Two-way audiovia 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

- 31. CCVM vs IPCCVM 1)Remote Viewing 2) Remote Recording 3) Wireless Capability 4) Video Analytics
- 32. CONCLUSION IP-based technology isthe 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.
