Introduction

• We are going to present our project “Video communication and Monitoring Software”.

• The objectives are-• Video conferencing between two user.• Multiple webcam monitoring from one PC.

• We have implemented it using Local Area Network (LAN).

• We used webcams for video capture.

Introduction (cont.)

• There are mainly two parts of our project.

• One is video communication• Another is monitoring system using

webcam.• We used TCP/IP protocol to establish

connection between server’s computer and client’s computer and also for peer-2-peer connections.

• We used C# platform for this project.

Challenges

• First we have to access a webcam to capture video and capture voice.

• We need a clear concept on TCP/IP protocol to send and receive video and voice stream from the client pc.

• Communicate with the IP address and port number through the TCPlistener().

• To receive multiple stream from client pc and able to access multiuser from server.

Requirements

• Webcam• Local Area Network• Windows Operating System

Technical details

• Our project is mainly Networking based.

• We used a library file to access the video from webcam called WebCam_Capture.dll

• We used stream class and TCPClient method of C# to send the stream through LAN.

• On the Communication part we also added full duplex voice support.

Technical details (cont.)

Video Monitoring System• It’s a Server Client System• Clients send the webcam video to

the Server • Server receives video from

different clients and shows them on a window.

Server Client System

Technical details (cont.)

Video Conferencing System• It’s a P2P (peer-to-peer)

communication system.• The Clients do send and receive

both.• Two persons are allowed to join a

conversation.• Also supports voice.

Peer-to-Peer System

Implementation

Video Communication System• It takes webcam images in interval

of 10 milliseconds.• Then takes the webcam images to

the MemoryStream.• and sends it through the TCPClient to the particular IP address of server with a unique port address.

Implementation (cont.)

Video Communication System• The server checks the ports for

data using TCPListener.• After receiving the data from

network stream it updates the pictureboxes with data according to port numbers.

How It looks

Implementation

Video Conferencing System• Duplex system, sends and receives at

same time.• Voice uses different Port address.

How It looks

Server Window

Applications

• Large Local area networks for communicating.

• Security purpose monitoring in Offices, Schools, Hospital, Shops etc.

• Digital classroom with e-learning system.

Limitations

• No multiuser support for video conferencing.

• Only receives data from Port numbers, cannot check from particular IP.

• Fixed numbers of webcams can be monitored. Not increases dynamically.

Future Plans

• Adding multi-user support in Conference system.

• Increase video smoothness.• Synchronize audio and video.• Use of dynamic form in Webcam

monitoring part of server.
