Whitnel First Baptist Church needed a solution for the secretary to be able to control the entry and exit during the day.  Each time someone came to the door,

they had to knock loudly, and she had to get up, go down the hall to the door to see who it was, then choose whether to manually unlock it for them.  Our solution was to provide a magnetic locking system and intercom, made by Aiphone, and a small camera with an LCD monitor in the secretary's office.  Now when someone comes to the door, they press the intercom button, and she can both see and hear who it is, then press a button on her desk to unlock the door for them.  If someone is inside, the door automatically senses their approach and unlocks itself for several seconds.
