OPTEX has announced the arrival of its TXI Series, a suite of high-mount outdoor curtain detectors crafted to enhance perimeter security for both residential and commercial properties. Designed to generate an unseen protective barrier along building facades, these detectors aim to resolve the issue of balancing effective human detection with the reduction of nuisance alarms in outdoor security setups.
The TXI Series is adept at providing early intrusion alerts before a trespasser reaches an establishment. These detectors are suitable for diverse applications including ground-floor security, balconies, warehouses, office buildings, and retail environments, where precise boundary demarcation is crucial.
Enhancing detection accuracy
High-mount detectors are typically oriented downward to monitor activity at ground level, but this can increase susceptibility to false alarms from pets, small animals, and environmental changes. Tweaking sensitivity settings often helps reduce false alarms but may compromise detection accuracy.

The innovative Triple AND Logic technology is central to the TXI Series. This system employs three distinct sensing areas to establish detection zones, triggering alarms only when all zones are simultaneously breached. Complemented by OPTEX's Super Multidimensional Analysis (SMDA) digital processing, which evaluates various motion characteristics, this combination enhances human detection dependability while lowering nuisance alarm incidents.
Challenges in high-mount detection
“Ensuring accurate outdoor detection at height has traditionally been a real challenge, often requiring installers to manage nuisance alarms through compromise,” remarks Masaya Kida, Managing Director of OPTEX EMEA.
“The TXI Series has been designed specifically to address this challenge. By combining our patent-pending Triple AND Logic and SMDA digital signal processing, it delivers true pet tolerance while maintaining reliable and accurate human detection. It represents an important development in addressing a longstanding pain point for installers in high-mount outdoor detection.”
Installation flexibility and security features
The TXI Series is weather-resistant and capable of functioning in temperatures ranging from -30°C to +60°C
Installers benefit from the TXI Series' adaptability, supporting various setups with adjustable mounting heights from 2.2m to 4m and a coverage area of 12m x 2.4m.
An optional look-down zone feature mitigates vulnerabilities typical in high-mount settings and can be activated as needed. The package includes brackets for secure installation and concealed wiring, with an optional ceiling/wall mount bracket available for additional adjustments. Security is further enhanced by features like a front tamper switch and a built-in accelerometer that detects alterations in angle or position.
Durability and model variants
For added protection, some dual-technology models feature anti-masking to combat intentional interference. Rated IP55, the TXI Series is weather-resistant and capable of functioning in temperatures ranging from -30°C to +60°C, ensuring reliable performance in diverse outdoor conditions.
The series includes four models to meet various installation needs: the wired TXI-ST (PIR) and TXI-DAM (dual technology with anti-masking), and the battery-operated TXI-R (PIR) and TXI-RDAM (dual technology with anti-masking). The battery versions integrate seamlessly with third-party wireless transmitters, providing compatibility with existing alarm systems.
OPTEX, the global sensor manufacturer, has launched the TXI Series, a new range of high-mount outdoor curtain detectors designed for residential and commercial perimeter protection. Built to create an invisible curtain barrier along a building façade, the TXI Series is designed to address the challenge of balancing reliable human detection and nuisance alarm reduction in external security.
By creating a controlled detection curtain at the perimeter, the TXI Series is specifically designed to support earlier detection before an intruder reaches the building itself. Common applications include ground-floor perimeter protection, balconies, warehouses, office buildings and retail sites where a narrow detection field can help define and secure the boundary of a property.
Reducing detection reliability
In high-mount applications, detectors typically look downward to detect activity at ground level, which can make them more susceptible to nuisance alarms caused by pets, small wildlife and environmental movement. In many installations, reducing sensitivity can minimise false alarms but may also reduce detection reliability.
At the heart of the TXI is OPTEX’s patent-pending Triple AND Logic, which uses three independent sensing areas to create three detection zones, with an alarm only triggered when all three zones detect simultaneously. Working in combination with OPTEX’s Super Multidimensional Analysis (SMDA) digital processing, which analyses multiple characteristics of detected movement to help filter environmental noise and support more stable performance as conditions change, these technologies help maintain reliable human detection while reducing nuisance alarms.

High-mount installations
For installers, the TXI Series has been designed to support flexible set-up across different sites. The detectors offer a selectable mounting height from 2.2m to 4m and a 12m x 2.4m curtain coverage area.
An optional look-down zone addresses a common vulnerability in high-mount installations and can be enabled or disabled depending on requirements. Installation is supported by included brackets to enable secure fitting and clean, concealed wiring, with an optional TXI-BKT ceiling/wall mount bracket available for angle and gradient adjustment. TXI includes multiple security and anti-sabotage features, including a front tamper switch for cover removal detection and a built-in accelerometer designed to detect changes in angle or positioning.
Providing additional protection
Dual-technology models also include anti-masking functionality to provide additional protection against deliberate interference. Rated IP55 for weather resistance, and able to operate in temperatures ranging from -30°C to +60°C, the TXI Series is designed to perform reliably across a broad range of outdoor environments.
The TXI Series comprises four models to support a range of installation requirements: the TXI-ST (PIR) and TXI-DAM (dual technology with anti-masking) in wired variants, plus the TXI-R (PIR) and TXI-RDAM (dual technology with anti-masking) as battery-operated models. Battery models are compatible with third-party wireless transmitters to integrate with a preferred alarm system.
