Design


The security industry is constantly changing and finding new solutions and approaches to perimeter security operations.  These materials will discuss some of the current and emerging design components related to security.

Inductance Loop Vehicle Detector Function – The Basics

Basic Principles:

An inductance loop is established with a wire wound in a saw cut in the pavement.

Wires from the loop are brought back to the inductance loop detector module.

The detector module oscillator powers the loop causing a field to form around the loop.

Limit Switch Function – The Basics

There are generally two types of limit switches used in perimeter security equipment: Mechanical and Proximity.​

Glass Hazard Mitigation Systems - Fragment Retention Film Option

Glass hazard mitigation systems are designed for reducing personal injury in the event of a bomb blast or severe weather event or for reducing loss of property in the event of a theft attempt​

Passive Devices for Barrier Safety

​Barrier systems are installed with various safety devices to help prevent the barrier from closing at inappropriate times. These safety devices vary based on location, barrier type, vehicular type, traffic pattern, security levels, theory of operation, and security personnel.

Active Devices for Barrier Safety

​Barrier systems are installed with levels of safety devices to help prevent barriers from closing on vehicles and/or pedestrians. These safety devices vary based on location, barrier type, vehicular type, traffic pattern, security levels, theory of operation, and security personnel.

Wrong Way and Over Speed

​Wrong Way systems are installed to detect vehicles approaching an ID check area in the exit lanes. While entrance lanes are controlled by security personnel, the exit lanes are usually not. Over Speed systems are installed to detect vehicles approaching an ID check area at a high rate of speed.

Control Panel Technology

​Controls can be as complex or as simple as you desire or as your system may call for. Initially, control panels consisted of boxes with simple pushbuttons to activate a barrier system. Due to advances in technology, control panels can now be more complex laser-etched panels made up of switches and lights.
