What's an infrared barrier?

Infrared barriers are perimetric protection devices that consist of a transmitter (TX) and receiver (RX) between which an invisible infrared beam is formed. Violating this beam by an intruder (e.g. passing through it) generates an alarm. {index=0}

Main types of IR barriers

• 2-Frequency: Standard barriers – e.g. model BX-100PLUS from Optex. {index=1}
• 3-Joins / Multi-complex: Increased resistance to false alarms – e.g. the AC-200 barrier has 3 beams. {index=2}
• 4-Flies: Very detailed detection, especially when protecting long sections. {index=3}
• Wireless IR barriers: For systems in which the operation of the cables is difficult — e.g. Jablotron JA-151IR 4– bundles. {index=4}

Advantages of using infrared barriers

• External protection: They are perfect for securing fences, gates and building circuits. {index=5}
• Minimise false alarms: Thanks to multiple beams (e.g. 2, 3 or 4), the barrier may require simultaneous intersection of several beams, which reduces detection by small objects like leaves, birds. {index=6}
• Adaptation to difficult conditions: Some barriers (e.g. Optrex AX-200TN) offer reinforcement regulation, protection against interference and robust housing. {index=7}
• Emergency power option: Some IR barriers are powered by batteries charged with solar panels, which increases their autonomy. {index=8}

What should we pay attention to when choosing the IR barrier?

• Range: Check the maximum distance between the transmitter and the receiver – varies depending on the model. {index=9}
• Number of beams: The more beams, the better detection and less risk of false alarms.
• Power supply: Will the barrier be wired (12-24 V) or on batteries/solar panels? :contentReference[oaicite:10]{index=10}
• Degree of protection (IP): For outdoor installation select barriers with weather-resistant housing (e.g. IP55 or more). {index=11}
• Security of sabotage: It is important that the barrier has contacts to signal the opening of the housing – it protects against manipulation. :contentReference[oaicite:12]{index=12}

Benefits of purchasing IR barriers in MikaShop

• Increase in perimetric collateral: Thanks to the IR barriers, you detect intruders before entering the protected area deeper.
• Flexible alarm system configuration: Possibility to choose the number of beams and type of power supply.
• Reduction of false alarms: Multi-band models significantly reduce the risk of misdetection.
• Applications in difficult areas: Solar power or high resistance to atmospheric conditions makes IR barriers work in many applications.

Most common questions (FAQ)

Does the infrared barrier work in rain or fog?

Yes — many IR barriers (especially with several beams) have algorithms to reduce false alarms, and the enclosures are sealed (e.g. IP55), which provides stable operation under difficult conditions. {index=20}

How can IR be mounted to make it work properly?

The transmitter and receiver must be precisely leveled and aimed at each other. It is recommended to use LED indicators for tuning and assembly at stable points. :contentReference[oaicite:21]{index=21}

Is the wireless barrier (e.g. JA-151IR) delayed? Is it suitable for an alarm system?

Wireless barriers are designed to operate with alarm panels. Jablotron's JA-151IR has even four beams and addressability in the JABLOTRON 100+ system. {index=22}
