Overview I.Problem II.Solution III.Packaging IV.Testing V.Bill Of Materials VI.Questions

I. Problem What is the problem? Current remote surveillance systems use limited resolution cameras, while high-resolution surveillance systems do not have remote transfer.

II. Solution What is the solution? The CellVeillance will allow for remote capture and transfer with an off-the-shelf digital camera.

III. Packaging Pelican Case – Weatherproof (NEMA-4 Standards) Polycarbonate face plate (laser-cut for precision) Removable lower faceplate for easy access to battery

III. Testing– Practical Constraints TypeNameDescription SustainabilitySelf TestThe device must be capable of remotely performing a self test. SustainabilityUpgradeableThe device must be capable of accepting firmware upgrades. Self Test: - Provides assurance - Capability to test all systems individually - Text file sent from the radio to the web server with diagnostics Upgradeable: - Add functionality - Fix bugs
