Security is always a key factor in protecting homes, businesses, and critical areas. Vu Tien proudly introduces the SENGATE Infrared Fence Sensor 4PB-50AD／4PB-100AD／4PB-200AD, offering a proactive and reliable security solution that effectively detects intrusions with high accuracy.

Versatile Protection Range for Various Spaces
The product comes in outdoor variants with coverage distances of 50m, 100m, and 200m. For indoor spaces, the protection range can extend up to 400m. This flexibility allows the sensor to be easily customized for various types of buildings and areas, ensuring maximum security both indoors and outdoors.

High Stability and Effective Environmental Interference Resistance
The infrared fence sensor is equipped with dual stability and superior environmental interference resistance. This minimizes the impact of external factors such as rain, dust, or strong light, ensuring stable and accurate operation in all weather conditions.

Minimized Infrared Reflection
Designed with low infrared scattering, the sensor reduces reflections from walls or the ground. This ensures signals are transmitted more accurately, minimizing detection errors and false alarms.

Selectable Beam Frequency for Flexibility and Efficiency
The sensor supports four selectable beam frequencies, allowing adjustment to suit specific environments. This not only enhances protection but also reduces interference and cross-talk between other security devices in the system.

Double Modulation Technology and A.G.C Circuit
Using pulse beam double modulation technology, the sensor ensures stable and clear signal transmission. Additionally, the Automatic Gain Control (A.G.C.) circuit allows the sensor to automatically adjust sensitivity according to real environmental conditions, optimizing performance.

Environmental Detection and Intelligent Alarm
With environmental detection features, the sensor not only triggers alarms for intrusions but can also detect adverse environmental conditions such as heavy rain, storms, or dense dust. This provides a more comprehensive understanding of the security situation.

Wireless (RF) Alignment Function
The sensor includes a wireless RF alignment feature, making installation and calibration easier and more precise. Users can check and adjust the device remotely without direct intervention.

Adjustable Beam Interruption Time
The sensor allows users to adjust the beam interruption time from 50ms to 700ms, enabling customization for specific monitoring situations. This helps prevent false alarms or missed alerts.

Weatherproof, Insect and Dust Resistant
Designed to resist rain, insects, and dust, the sensor operates reliably in all weather conditions. The IP55 rating ensures stable and long-lasting performance even in harsh environments.

Conclusion
The SENGATE Infrared Fence Sensor is an optimal choice for both outdoor and indoor security systems. With outstanding features such as high stability, interference resistance, and versatile protection, this product promises a comprehensive and effective security solution for any facility.
