In general terms however, an occupied building with good perimeter protection faces less of a risk of break-in than an unoccupied building. This is particularly true in smaller buildings. If the building is very large or multi-storied, the relative level of security changes. The best approach in these situations is to zone the interior sensors so that unoccupied portions of the building are protected. This can be easily done with card key or keypad technology.
Employees can deactivate the motion sensors in their work areas but leave other areas armed.
This method can also be used to control employee movement within the building. If certain areas are off limits to employees, they are not given access right to disarm the sensors protecting these areas. Discuss the zoning concept with your alarm company. You may find that it improves security for your employees as well as your building. Is any of this available to the general public.
