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.

Internet

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

Type Name Description

Sustainability Self Test The device must be capable of remotely performing a self test.

Sustainability Upgradeable The 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
