The diagram above is the SECAM Component Diagram. The SECAM Component Diagram outlines system
interaction between our primary system componens, SysControls, WebControls and SECAM Secure SyServe. The
component SysControls is a locally installed application on a local computer that facilitates locate secure control
over the implemented security camera. The Component WebControls is our primary system for configuring,
modifying and accessing data relating to SysControls and the SECAM SECURE Database. The final component
SyServe is the localized server module that facilitates connections between SysControls and the SECAM SECURE
Database. SyServe prevents malicious activitiy originating from hostile attack on a SysControl client, validates the
legitimacy of a connection from a localized SysControls client and facilitates a secure encrypted connection
channel between the client installation and the server cluster.

SyServe operations can be seen in the above diagram. If the current number of connections supported by
current instance of the database exceeds a specified limit, SyServe expands localized support by migrating and
initializing a new server instance which can handle a new specified number of connections. This method of
migration allows for an efficient use of resources and optimized performance for all secure connections.

The diagram to the left, demonstrates the process in which the
camera and related system components identify and interact with
WebControls. This diagram also incorporates continuous polling of the stop
request throughout the current streaming iteration. It should also be noted
that this system and process is expanded on future diagrams.

The below diagram demonstrates a request process of internal system components. The system
components involved in this diagram are WebControls and SECAM SECURE Database. More specifically this
diagram specifies a process of querying the SECAM SECURE Database. As seen in the diagram there is a UI call from
WebControls, a validation process, notification process and the execution of a specified query.

The diagram below or on the next page is the flow for the component SysControls; the redistributable
software application in charge of controlling, maintaining and supporting the security camera and related system.
This diagram shows the generalize initialization process this component goes through to check if all system
components are functional. If the components are not functional then the appropriate actions are taken for
notification processes and error handling.

The diagram below describes the interaction between the components SysControls, WebControls and
SyServe. This diagram demonstrates how computer installation is validated, secure channels are requested, how
secure channels are initialized and how data is sent to the SECAM SECURE Database, how facilitated through these
components and how data is temporarily stored and supported for requests to view a stream by the WebControls
component.

The diagram below involves the interaction between SysControls and WebControls. This diagram depicts
the process in which a user logged into WebControls is able to send requests to SysControls. These requests
include stopping a video stream, directly accessing a video stream and updating settings of the component at the
system level.
