Types of perimeter protection devices
To create strong perimeter protection systems, security teams need multi-layered solutions that deter intruders and provide the highest levels of situational awareness. When you have a robust security system, you can ensure adequate perimeter protection. With these types of perimeter security, you can meet the needs of your specific property.
Perimeter CCTV System
Strategically-positioned video surveillance cameras such as fixed cameras enable security teams to monitor vulnerable areas, analyze and record video footage and detect suspicious activity. The cameras should be positioned to provide the widest possible coverage of vulnerable areas with the fewest camera. Businesses can also invest in panoramic security cameras that provide 360-degree coverage of your perimeter. A CCTV security system should also capture clear images in all light conditions.
Perimeter access control
An access control system enables security teams to verify the identity of employees and visitors wishing to enter the site via perimeter doors or gates. Visitors might include contractors, service or maintenance staff, delivery drivers or people visiting on official business. Employees gain access by presenting different credentials at an access control reader fitted to a perimeter door, gate or other type of barrier. The reader transmits credential details to a controller that validates them against a database of authorized users before issuing a door release signal to allow access or restrict entry.
Perimeter Physical barriers
Walls, fences, gates, doors and barriers, such as bollards, form a physical perimeter protection system that can deter intruders and ensure that only authorized personnel or approved visitors can enter via a perimeter access control system.
Electrified Fences
Electric fencing and its form may vary according to its application. Traditionally electric fencing is associated with farming or livestock security; however, it is frequently used for perimeter security for commercial premises. Electric fencing acts as a deterrent to intruders but also acts a barrier to prevent escape, critical for livestock or prisons, for example.Usually it is not the fencing itself that is ‘electric’, but instead wires on top of the existing fencing or wall. The wires are powered by an ‘energiser’ which sends voltage down the wires and creates pulses. Depending on application and placement, electric fencing may be powered by mains, battery, or solar.
Microwave Barriers
Microwave barrier develops an electromagnetic beam using high frequency microwaves that passes from a transmitter to a receiver, creating an invisible but sensitive protection wall. When the receiver detects a difference of condition within its beam, it begins a detailed analysis of the situation that, if considered a real intrusion, provides an alarm signal that can be treated in digital form. The difference of Microwave Barrier and infrared barrier is the protection area and environment endurance. On these two aspects, Microwave Barrier performs better than Infrared Barrier. Microwave Barrier can form a cubic protection space and not just a line.
Perimeter Security Sensors
Sensors located in key positions on or near entrances and fences detect movement and other types of disturbance, which can alert security teams to intrusion or other activity. Buried sensors can be installed on walls or fences, buried below ground (ground sensors) or fitted above ground in selected locations. Both indoor and outdoor perimeter security options are necessary. There are Seven main types of security perimeter sensors:
Motion Sensors
You can place motion sensors throughout the outside perimeter to detect movements. These sensors use infrared rays to sense motion. There are two types of motion sensors: active and passive. If the sensor is active, it will use a power source to detect any motion. However, a passive system only sends an alarm when there is a change in movement or temperature.
Spot Vibration Sensors
Our door and window sensors have an advanced filter that can distinguish the movement caused by intruders from environmental factors. With our highly sensitive sensors we can detect the burglar before he even enters the house or business. When the shock sensors detect an impact or tampering, and distinguishes it from an environmental effect, our certified ARC checks and clarifies the break in for you. They will then contact you and, if necessary, call the emergency services on your behalf. This type of security system uses a wireless perimeter alarm to monitor the property. In many cases, these sensors are placed on a window, access point, or doorway. When it detects a vibration, the sensor triggers an alarm.
Microphone Sensors
Sound sensors can be used to keep track of perimeter security. With a microphone cable, the security system monitors the entire fence line. If someone tries to climb or cut the fence, that microphone picks up the sounds and transmits an alarm to the security center
Seismic Sensors
Seismic sensors do not detect earthquakes, but they can detect vibration within a specific area to activate an alarm. When someone tries to breach a particular space, these components pick up those vibrations and alert the security team.
Electrostatic Field Disturbance Sensors
Electrostatic field disturbance sensors are becoming commonplace for many property owners. These devices create an electric field with the help of conductors and grounding wires. When the electric field changes, an alarm alert is created.
Fiber Optic Detection System
We offer a complete range of fiber optic based intrusion detection systems for protection and pipeline security that offer Long range – up to 80km of sensor optical path length for some systems. One advanced feature is a fiber optic detection system that can detect any breach or changes near the fenced areas. Many property owners use this type of system to ensure that their perimeter remains secure. These detection systems can be used around fences and walls. They are also used to cover a large area of the outside perimeter. Some systems can even be used in combination with security lighting to deter any unwanted visitors.
Radar System
The radar perimeter protection system utilizes radar technology to perceive dynamic and static changes in the surrounding area by emitting radio waves and receiving their reflected signals. These radar waves can penetrate various weather conditions and operate day and night without hindrance, functioning effectively in adverse weather or complex terrain. When individuals, vehicles, or other objects enter the monitoring area, the radar system promptly identifies them and notifies security personnel through an alarm system, enabling early warning and intervention. Radar systems can be installed in large open spaces that are difficult to monitor. They can detect the presence of intruders or vehicles at distances of up to 1500 meters.
