Wireless camera(FSK control)

Basic of FSK(Frequency Shift Keying):

Frequency-shift keying (FSK) is a frequency modulation scheme in which digital information is transmitted through discrete frequency changes of a carrier wave. The simplest FSK is binary FSK (BFSK). BFSK uses a pair of discrete frequencies to transmit binary (0s and 1s) information. With this scheme, the “1” is called the mark frequency and the “0” is called the space frequency. Wireless camera control fall in the security system category and one of the highest rating project in 2012 for me.

the aim of this project is precision control of camera(CCTV) rotation left and right with the FSK(Frequency Shift Key) technology. this project have three sections:

  • Camera Block
  • Control Panel
  • Av Receiver Block

Whit the control panel you can control wireless camera to left and right and you can also turn off and on whit the three momentary keys.

Camera block includes convenient Stepper motor for camera rotating up to 360degrees,micro-controller board for process and order, micro switch sensor for identify position of camera, FSK receiver module for receiving orders from Cpanel and antenna for receiving electromagnetic waves from cpanel.

Cpanel includes FSK transmitter module for sending orders to camera block, three keys for selecting directions of camera move and turn on and off camera, 9v battery for power supply, antenna for sending electromagnetic wave to camera block, Blue LCD for indication what happened for camera.

AV receiver is one of section that connect to TV and you can see images of camera.
