Dear Members,

I currently have a project titled "Witness Camera".
My plan is to use Camera Module with JPEG compression + AVR Microcontroller +
Storage + wireless transfer

in a cost effective manner.

I am awaiting for anyone here and welcome any suggestions about the

1) Methods of wireless transfer possible to integrate with AVR.
2) Development Board Support

Thanks in advance

George Neil

if you are going to send single frame (image), there are
several manufacturers for Camera Modules, Transceivers and AVR borads.

I am familiar with some camera module manufactures like COMedia.

I am planning to use AVRmega series. now i want to know about the feasible wireless transferring methods supported by AVRmega series.

Hello,

I think nobody is here to give me a support regarding witness camera design.

Let me make the concept more clear to you. My plan is

1) CMOS Camera Module – Gives images in JPEG format via UART

2) PIR Movement sensor – Triggers the snapshot feature

3) AVR Microcontroller – Takes this image data and stores in 1 GB SD card in FAT 16/FAT32 format
[Stored w.r.t Date and automated delete feature depending on the space left in the SD card]

4) BT_Module – Should transfer this images in SD card to a BT_PC.
I want to know

5) What all stacks need to install in the microcontroller
6
) How much memory is needed to configure the BT_Stack in the microcontroller.
7) What is needed in the PC side [Software and Hardware

Hello,

Firstly you should get a Bluetooth module. Here are some: http://www.free2move.se/prod_mod.shtml

You can learn how you should interface it from the documentation of the BT module.

You should you Serial Port Profile. Then on the computer side you will need a bluetooth dongle and you can write a program like any serial port program.

Check out the May 2007 issue of Circuit Cellar magazine. Has just
about everything you are probably asking for. Camera, PIR, AVR, SD
memory, Voice systhesis..............

Do anyone have idea about the COMedia C-328 Camera Module. I am planning to buy that.
