PROBLEM
• Current security camera systems available on the market are expensive and complicated.
![Page 5: Mid-Semester Presentation Senior Design I September 29, 2011](https://reader035.vdocuments.us/reader035/viewer/2022062409/5697bfa71a28abf838c98faf/html5/thumbnails/5.jpg)
SOLUTION
• The Home Surveillance Device will be a cheap, easy to use camera that takes a series of pictures when motion is detected.

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.)
![Page 8: Mid-Semester Presentation Senior Design I September 29, 2011](https://reader035.vdocuments.us/reader035/viewer/2022062409/5697bfa71a28abf838c98faf/html5/thumbnails/8.jpg)
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.
![Page 10: Mid-Semester Presentation Senior Design I September 29, 2011](https://reader035.vdocuments.us/reader035/viewer/2022062409/5697bfa71a28abf838c98faf/html5/thumbnails/10.jpg)
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
![Page 11: Mid-Semester Presentation Senior Design I September 29, 2011](https://reader035.vdocuments.us/reader035/viewer/2022062409/5697bfa71a28abf838c98faf/html5/thumbnails/11.jpg)
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
