You’re responsible for server room security. You’re concerned about physical theft of computers. Of the following, which would best be able to detect theft or attempted theft?
A) Motion-sensor activated cameras
B) Smart card access to the server rooms
C) Strong deadbolt locks for server rooms
D) Logging everyone who enters the server room

Motion sensor activated cameras are the ones which actuate a trigger when any sort of motion is detected by them. They can play alarming sound, send e-mails and zoom the frame of motion as a response to the detected motion.

Motion sensor cameras can be of two types:

1. Fixed view camera

2. Rotating view camera

Fixed view cameras are in fixed position and they always point in the same direction for the view while the rotating cameras are the ones which can change their direction of view.

For a small and high security space we can use the fixed type camera so that we do not miss any suspicious movements. For wide areas and distant vision we use rotating cameras.
