This document provides an overview of IP-based closed-circuit video monitoring (IPCCVM) systems. It discusses the components of traditional CCVM systems and how they differ from IPCCVM. IPCCVM uses internet protocol to transmit video and control signals over Ethernet. This allows for remote viewing and control of cameras. IPCCVM provides advantages like higher resolution, wireless capability, video analytics and remote access/storage. While initial costs are higher, IPCCVM is more flexible, reliable and upgradable than traditional CCVM systems. The document concludes that IPCCVM represents the future of video surveillance technology.

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.

7. Major Units of Old System CCVM
CCD Sensor
 Cameras
 Lenses
 Switching unit
 Monitoring unit


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.

10. 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


11. Lenses
It is fixed in front of the camera and is used to focus the
required object on the photosensitive plate.

12. 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)

13. 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):

14. 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

24. 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.

25. 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)

26. Decomposition of an IPv4 address from dotdecimal notation to its binary value:

27. Decomposition of an IPv6 address from hexadecimal
representation to its binary value:

28. Potential Advantages:

2) Remote Recording
3) Wireless Capability
4) Video Analytics

32. 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.
