| \\ Although surveillance systems may be used to provide information to address several surveillance objectives as the design of surveillance is strongly dependent on the surveillance objective we limited users to choosing only //**one**// surveillance objective for their surveillance system. This should be the **//primary//** surveillance objective. If other (secondary) surveillance objectives are relevant, the user should list that in the surveillance context information (step 1.6) and there is also an opportunity to indicate whether each of the components that contribute to the system address more than one surveillance objective in step 3.\\ \\ | \\ Although surveillance systems may be used to provide information to address several surveillance objectives as the design of surveillance is strongly dependent on the surveillance objective we limited users to choosing only //**one**// surveillance objective for their surveillance system.

Hence, surveillance purpose should depend on the outputs needed to support decision-making and thus be policy-driven.
