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.

Power The 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 Time The 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.”

Usability Storage The 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
