BackgroundCurrent System at the Portland Bureau of Transportation

(PBoT):• Antiquated (VHS Tapes)• Installation is difficult (weighs over 70 lbs)• Requires frequent maintenance (lasts only 3 days

between visits)

Results: Camera• LinkSprite JPEG Color

Camera TTL Interface• Preset commands to take

a picture and receive it• Can set picture size and

control how often a picture is taken to optimize for client needs

Results: Gumstix Processor• “Brain” of the device• Coordinates the receiving of the picture

from the camera with sending the picture over the network

Results: Storage on Base Unit

• The base unit is any computer with an internet connection

• All pictures are stored in a directory specified by the user

• For the client, this will be a machine at the PBoT Headquarters

ConclusionsWe have greatly improved the device:• The user can access the video feed at a remote

location, as the pictures are sent• Device is much lighter

Other improvements for future development• Smaller, lighter battery• Optimize software for more frames per minute
