Active Vs. Passive Barriers

Save

Security provided by barriers is available with many differing degrees of safety. Choosing whether to have a permanent barrier or something that can be moved with relative ease depends on various external factors including safety access and the value of the item being safe guarded.

Active Barriers

  • Active barriers create a secure environment by blocking a path or route but open or move to allow passage when necessary. A door or security barrier is active because it can be moved to allow access but keeps unwelcome visitors outside.

Passive Barriers

  • Passive barriers, such as a brick wall or a castle moat, are fixed structures designed to stop access. A passive barrier is relatively impenetrable and immovable. No manual or electronic action is required for the barrier to perform its function.

Choices for Security

  • Your choice of barrier is very much dependent on why you need it. Maximum security needs a higher ratio of passive barriers with minimum access via active secure barriers. If you are using barriers for information or direction, then active, movable barriers are the only option.
