2. Project Description. This project aims to monitor an area through a camera, transmits the video wireless.

5. Applications. Houses and residential Companies and governmental buildings Labs and scientific work places Shops and out doors Hospitals Children watching Security

6. Contents Of The Project

7. Software. Server on local computer : 1.Serial port and serial data transmission. 2.Matlab. 3.C#. 4.Networking. Client on another local computer: 1.Serial port and serial data transmission. 2.Networking.

8. Serial port and serial data transmission. The default vales of the serial port settings are: Baud rate: 115200 bit/sec Data Bits: 8 Stop Bits: 1 Parity Bits: None Sender opens the image, release it immediately, allowing matlab to use the resource (file) and convert it to array of bytes.

9. Creates the header with the size of data. 4 bytes. Send the file. If any error occurs it can be handled through dropping this image as another will be received shortly. Buffer should be out of bytes(all sent) to take new ones. Handshaking is their. We used invoke and delegates methods to solve the threads conflict problem.

10. Matlab. Tracking is done through it, in addition to preparing the video file on the computer. It can track up to 4 moving objects. The file is written in binary form. Takes around 30 frame/sec. Frames are compressed.

13. C#.

14. Search for the installed serial ports on the computer when the user clicks on the “Port" button and port is chosen. The program is user friendly, where you can used it as transceiver, according to your application. A specific folder should be selected to take the video from, which is prepared by the matlab. It takes new frame with a certain delay, which gives the zigbee enough time to send the frames without errors. It takes all extensions forms( JPEG,PNG,TIFF...)

15. Networking. The wireless transmission done through zigbee module, uses the WIFI system, on frequency 2.4 GHZ. The transmission can be done on various channels and we have to select the same channel in both zigbee modules to do the wireless transmission.

16. Hardware. Wireless module (zigbee) Camera Microcontroller and keypad

17. Wireless module (zigbee). Most of the application Xbee used in so far is simple (directions), but we could send video through it for the first time. Features: 1.High serial bit rate up to 115.2Kbps. 2.Long range data transmission: Indoor/Urban : up to 30m Outdoor line-of –sight: up to 100m Transmit power: 1mW (0 db)

18. 3.Low power : TX current:45 mA (at 3.3v) RX current:50 mA (at 3.3v) Power-down Current:<10µA 4.Can work up to 24/7 under hard conditions. 5.Works as transceiver.

19. Microcontroller and keypad. Microcontroller and keypad. The microcontroller have a PICC program. Which takes a 3-digit code, compare it. If it was correct it stops the system through cutting the power feeding the module. If the code was wrong or not inserted the module keeps sending data.

20. Features of the project. C# & Matlab doesn’t have to be installed. Framework is enough and pre-installed with windows. NO internet is needed or wires. Covers a relatively wide area. Low cost. Video taken by camera is previewed on the application in the client and server computer. This video shows the detection process done through matlab.
