Security-Cam#

Security-cam continuously compares the previous image and the current image. If an images changes by more than a preset threshold, the image is saved as a jpeg to the MMC card. This is a great project to leave somewhere for a long time in hopes of finding an interesting surprise.

The release version of security-cam had a bug that has since been fixed. Attached below is an updated firmware image and a replacement main.c file with the fix. The fix was committed into subversion at r503.

Setting Up Security Cam

  • You will need the following:

    • CMUcam3, with power and a serial cable

    • MMC or SD card

    • MMC/SD card reader on your PC

  • Format the Memory Card using the FAT filesystem

    • DO NOT USE FAT32 which is the Windows Default

  • Flash the security-cam.hex firmware file onto the CMUcam

  • Turn off your CMUcam3 and bring it to the area that you want to monitor

  • Insert the MMC card and turn the CMUcam3 on

    • Make sure you see the red led blink if there is motion in front of the camera
