1. A cloud-computing surveillance system comprising: at least one server computer having a processor and a memory, constructed and configured in network-based communication with a multiplicity of remote input devices having input capture mechanisms; inputs captured by the remote input devices transmitted within a secure messaging communicated over the network; wherein the inputs are received, authenticated, and indexed by the at least one server computer and stored in a corresponding database; wherein the inputs are processed and analyzed based upon at least one profile for a surveillance environment, a surveillance event, and/or a surveillance target, for providing a near-real-time analysis of the inputs to determine a status of security.
