Introduction

Perimeter protection system is a smart system that is used to identify and prevent the intentional penetration into the site. This system is based on various sensors to detect and announce the intrusion warning from surrounding obstacles into the area. The selection of sensors and communication platforms is done according to the geographical location and characteristics of the monitored area. This system, in combination with all kinds of physical barriers such as fences, barbed wires and walls, is evaluated as a strong and reliable barrier against the penetration of attackers. Imen Dezhlock, as one of the main consultants in the field of Safety & Security engineering, with the help of its technical team, has produced completely native products to create impenetrable systems with the lowest false alarm rate. Using the effective efforts of the country’s elites in the fields of electronics, mechanics, telecommunications and software, this collection has succeeded in producing various sensors to detect the penetration of unauthorized agents, such as multi-purpose smart wire fences and laser fences along with “Homaye Hefazat” comprehensive management software.

The main features of the “Homaye Hefazat” system

The three essential features of this system are:

• “Sensor” with the aim of identifying unauthorized people
• “Surveillance cameras” with the purpose of investigating the method of penetration, location of penetration and recording operations
• “Software” in order to manage and guide the performance of the system and register and announce the reports related to the system to the operator.

The items in this system are controlled and monitored by the system management software using different types of telecommunication platforms such as optical fiber, radio links, and internal network, and at the time of an incident, the environmental sensors in the area carry out the detection operations and alarm notifications and send appropriate notifications to the software . At this time, the software, using surveillance cameras, storing the steps of the intrusion operation, in the mean time informs the guards of the complex about the occurrence of the intrusion and the quality of the operation, using audio and video alerts .the reporting system of the software is capable of checking and monitoring the events that happened in all different time periods along with the recorded images.

Introduction of system components

Laser fence

The laser fence has been designed and produced in competition with the microwave system. In the laser fence, digital and photonic technologies are used to detect the location of intruders. Technical specifications of the laser fence system

Laser

• Consisting of fourteen smart laser beams

Body

• Consists of a self-protection system including: (detection of impact to the body, applying electric shock to the attacker and cooling system)
• Nano coating on the optical valves
• Isolated stabilizer system for lasers and receivers
• lightning arrester
• Ability to install solar cells on it
• Appropriate and changeable dimensions for different environmental conditions
• Installation of unbreakable and anti-scratch laminate on light valves
• Human detection system around the body
• Body isolation from the equipment

Other features

• The laser wall or fence can be produced in several color ranges (visible) and invisible. Visible spectrometers are for places where a visual indicator is needed and the visibility of the beam can be one of the warning signs, and in places where the visible spectrum and visual beam cause special sensitivity, invisible beams with X and IR wavelengths can be used.
• Sound system in each box in the form of a siren or speech (pre-recorded)
• The distance density between lasers can be changed depending on different applications. For example, high density in places where animals move and low density in areas where large animals and humans move. In addition to reducing costs, this density helps the accuracy and performance of the system in order to separate the infiltrating entity.
• It has a system for reporting malfunctions and possible defects in the entire system along with the ability to remove the defective device from the system
• High performance and reliability in harsh environmental conditions
• Can be operated by solar energy
• Energy consumption control system
• The power consumption is about 20 w
• Working voltage 220 volts alternating or 12 volts direct
• Ability to build and design in different packages for different environments, including mountainous, desert, urban, hot and humid, dry and cold weather.

Smart electro-fence

The SADAF wire fence, which is designed and produced in competition with the microphone cable, can be installed on the wall, fence and ground.

Technical specifications of SADAF wire fence

• It has intrusion detection sensors to determine the entry point in a related zone. (20 meter areas)
• It has support bases at 20 meter intervals.
• It has 8 strands of hot/cold galvanized wire.
• Anti-deception: The intelligent design of the wire fence system has made it impossible for attackers to deceive the system or pass through it, that is, due to the voltage difference created between the fence wires and also the voltage difference with the ground if the voltages become zero. As mentioned, the system gives an alarm and protects the system from being deceived and preventing it from causing a shock.
