triggering multiple devices

When the output of a sensor (e.g. motion PIR) is used to trigger more than one device (e.g. two video cameras and an alarm system) what is the recommended approach to triggering multiple devices? Can the inputs of the cameras and alarm simply be wired in parallel and triggered together with no additional electronics? Or, should the output of the PIR sensor be used to trigger a multi-pole relay that is used to trigger each of the other devices separately? If the latter solution is recommended or required, what manufacturer / part number would you typically use?
