Perimeter Protection System

The perimeter of a building is its outer boundary, and it serves as both the main entrance and exit for the entire space it encloses. The enclosed premises, which are only accessible after passing the perimeter's first point of entry, can be a house, business, bank, warehouse, defence cantonment, etc.

Any building's perimeter should be protected because it is the first and most important layer of security. This is where every theft or act of sabotage begins, making its protection the most crucial and challenging aspect of the security system.

Types of Perimeter Security System:

• Electrified Fencing: Fencing or electrified fencing is the most traditional way of perimeter protection being implemented by many small budget industries. This method of protection is beneficial for small scale industries that do not have much concern about protecting their property and materials.

• Photoelectric Beam Detector: This type of security system works on the principle of infrared beam detection. The system consists of a transmitter and a receiver mounted in line with each other on the outer boundary of the premises. The transmitter continuously transmits the infrared beam and the receiver at the same time detects it. Whenever there is any disturbance in the path of the infrared beam, the sensors detect it as an intrusion attempt and alert the owners.

• Passive Infrared Detector: Passive Infrared detectors scan the energy released by objects in the form of Infrared and do not emit any. The sensors embedded in the security system remember the infrared image of the surroundings and keep on measuring the energy levels. Whenever there is an unauthorized entry, the sensors detect that due to a change in the energy level of the surroundings. These changes in the energy level send warning signals to the system and alert the respective security persons.

• Video Surveillance: Video Surveillance system is the security solution that keeps on recording whatever comes in its range. The recorded data gets stored on the DVR or cloud depending on the requirement of the user. The live footage of the focused area can also be watched through mobile or tablet applications from anywhere and at any time.

• Access Control System: The Access Control System is installed at the entry and exit points of a premises preventing tailgating activities. This type of security system allows only the authorised persons to enter and thus those making intrusion attempts by following the authorised person stop by themselves.

• Laser Based Intrusion Detectors: These types of security systems work on the principle of detecting intrusion with the help of a laser. The device is mounted at a place like a CCTV camera and made to focus on a particular area. The device forms a particular pattern to cover a wall or fencing and whenever someone comes into its detection zone, the alarm goes off immediately to alert the security people.

Working Principle of Perimeter Protection System :

Technically speaking, PIDS (perimeter intrusion detection systems) operate differently depending on the detection technologies they contain. However, regardless of the technology that the devices employ, their primary function is to identify intrusion attempts and issue a warning.

The sequential steps that all devices follow are as follows :-

1. The mounted devices continue to operate in accordance with their specific roles and, if any, detect any unusual movements within their detection range.
2. The devices alert the control panel, which serves as the brain of all connected devices, when they detect movement.
3. The control panel reacts to the warning message in accordance with the pre-established rules and notifies the security staff of the attempted intrusion.

Applications :

• ATMs and Banks
• Airports
• Warehouses
• Homes
• Data Centres
• Defence
