PROBLEM Current security camera systems available on the market are expensive and complicated.

SOLUTION The Home Surveillance Device will be a cheap, easy to use camera that takes a series of pictures when motion is detected.

SYSTEM OVERVIEW Motion Sensor RTC Camera Microprocessor Storage Power

CONSTRAINTS: TECHNICAL Name Description Motion Detection Range The HSD must detect motion at least 25 feet away. PowerThe HSD must operate from a standard 120V wall outlet, and it must be able to operate on battery power for at least 1 month (based on 150 pictures a day.)

CONSTRAINTS: TECHNICAL Name Description Minimum Resolution The HSD must take pictures at a minimum resolution of (320x240). Picture Storage The HSD must be able to store at least 1 month worth of pictures. Camera Warm up TimeThe HSD must be able to take a picture within two seconds of motion.

CONSTRAINTS: PRACTICAL Type Name Description Manufacturability Size The HSD’s dimensions must not exceed 4” x 3” x 2.” UsabilityStorageThe HSD must have an easy – to – use removable storage device.

CONSTRAINTS: PRACTICAL Manufacturability: Size The HSD must have dimensions that will not exceed 4"x3"x2.” This will allow the HSD to: Be placed anywhere in a room Go unnoticed anywhere it is placed Be discrete and aesthetically pleasing

CONSTRAINTS: PRACTICAL Usability: Storage The HSD must have an easy to use storage device that: Any modern computer can use without separate cables or devices. Has a large storage capacity Is easy to remove Is easy to retrieve data
