I would like to select a single motion detector to drive lighting in a 70 foot hallway (straight corridor approximately 6 ft wide). A 70 by 6 foot rectangle is to be covered. If it is necessary to use more than one detector then so be it, however less is more.
What are the specifications of a motion detector that describes it range in the above context?
The current switch is a mechanical timer with maximum of 20 minutes. A traditional switch, which can be left on indefinitely is not acceptable in this particular scenario. The switch should stay engage lighting for 10-20 minutes.
