This document describes an intelligent wireless video monitoring system using a computer. The system utilizes a video camera attached to a stepper motor that can rotate automatically towards a reference point. The camera collects images that are transmitted wirelessly via an AM transmitter to a distant receiver. The system is designed for portability and wide viewing range without needing wired infrastructure. It detects intrusions using an infrared proximity sensor and the computer controls the stepper motor movement. The computer also displays the transmitted video footage. The system has applications for border security, sensitive labs, and military zones. Potential future work involves implementing tracking algorithms and facial recognition.

2. INTRODUCTION
 To develop efficient wireless video monitoring system.
 The principle of remote sensing is utilized in this project to
detect
 A video camera collects the images from the reference
point and the collected images

3. Why wireless video surveillance
 Can be used to monitor remote location.
 Can be used in locations where wired infrastructure
doesn’t exist.
 Less expensive than wired solutions.
 Video images can be transmitted over a network

4. PROPOSED SYSTEM
 The video surveillance unit is designed for the portability and the
widest possible viewing range.
 The unit consists of a stepper motor that drives the camera towards
the reference point automatically and a transmitter section which
will transmit the images collected by the camera to a distant end.
 The robotic action made by the stepper motor is attached to the
camera, this allows surveillance of maximum area with just one
single camera.

5. High resolution Video camera
6. LEDs etc.

7. Software Requirements
1. Embedded C
2. Keil u Vision
3. IAR workbench
4. Code Composer Studio

8. Infrared Section
 The infrared proximity detection system is designed for
detecting the presence of a person who is inside the restricted
zone within the range
 The function of the detector circuit is to radiate the energy
into space through IR-LED and detecting the echo signal
reflected from an object.
 Portion of the transmitted energy is intercepted by the target
and re-radiated in multiple directions and this energy is
collected by the receiving LEDs and is fed to the computer.

9.  When the computer receives the signal, it drives a stepper
motor towards a particular reference point.

10. Stepper motor and computer
 The computer plays a major role by identifying and
locating the interruption made by the human body.
 Based on this input the computer directs the stepper
motor control system to follow the obstruction.
 All the software's required for the functioning of this
module is developed using C language.
 The computer also displays the video footage of the
person moving in that particular region.

12. Transmitter
 The output of the video camera which is pure composite
video signal and is fed to the AM transmitter
 AM transmitter consists of three sections:
1. VHF Oscillator
2. Modulator
3. Final stage amplifier

13. CIRCUIT FOR TRANSMITTER SECTION

14. Applications:
 In Borders security
 In Highly sensible lab
 In Military zones etc

15. Future work:
 We can implement the tracking algorithms to track
multiple intrusions at a time .
 Image database of potential attackers can be included in
the system and facial recognition algorithm can be
implemented to match the intruders with the information
in the image database.

16. Conclusion
 A system design for wireless video surveillance,
including video capture with automatic camera control
and data transmission is achieved through this project.
 Wireless camera based surveillance systems transform
video surveillance from a data acquisition tool to
information and intelligence system.
 Real time video analysis provides smart surveillance
system with the ability to react to a real time activity.
