Custom Security Floor-plan App

We would like to have an app that would allow our customers to create a custom surveillance system layout on top of a building floor plan. The user would 1. Upload a floor plan of their facility or home to the app. 2. Draw their first wall with some kind of line tool and define a length for that wall. 3. Draw the rest of the walls in their floor plan. 4. Drag cameras from a "bank" of products and place them on the floor plan where desired. They should be able to spin the camera to have them facing the right direction. Each camera will have a defined field of view or angle and a distance rating. These will be reflected in the camera overlay. 6. The camera overlay should detect the defined walls and "spill" into areas that the camera will cover, but not where blocked by a defined wall. See attachment for an example of the "fill area" behavior. 5. Request a quote or purchase the custom built system from our magento site. We would need full integration into our Magento store so that customers can view current products, images, descriptions, specs, prices, availability, etc. right in the app. Purchases within the app should be integrated into the magento store and [login to view URL] gateway.
