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.

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.

Camera UnitA 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

Lenses

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

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)

IrisThe ability to control a camera’s iris opening plays an important role in image quality.

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):

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

1) Frames per second :

2) Pan Tilt Zoom (PTZ):

3) Cameras with special accessories

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.

Architecture of IP CCVM SYSTEM:

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:

3) Fixed

4) Fixed Dome

5) PTZ

6) PTZ Dome.

Process Involved In Working Of IPCCVM

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. 

 The two parts of an IP address  192.168.10.10 192.168.10.20.

IP Addressing Fundamentals:

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:1) IP Version 42) IP Version 6

Decomposition of an IPv4 address from dot-decimal notation to its binary value:

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

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

Facial Recognition Through IPCCVM

Potential Disadvantages:

Higher initial cost per camera

High network bandwidth requirements

Technical barrier

System becomes open to hacking via internet.

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.
