The WXS series is OPTEX's latest 180° outdoor intrusion detection sensors with flexible range detection and settings, as well as a selectable low (0.8 - 1.2m) or high mount (2m) option, self-learning IR and intelligent anti-masking. Ideal as approach or flat roof protection for residential and commercial premises, the sensor is equipped with the Shield advanced features including double conductive shielding to avoid false alarms triggered by bright sunlight or RFI, and automatic walk test.
Secure your home with the gold standard of passive infrared intrusion detection. Customisable to your requirements the WSX offers stable detection whilst reducing false alarms.
PIR sensors rely on detecting the infrared radiation emitted by heat-emitting objects. This emission, invisible to the human eye, is discernible to sensors operating on infrared wavelengths.
The WXS series features models that combine PIR with microwave technology, thus creating a dual tech sensor. PIR and microwave algorithms provide the ultimate stability in detection performance as the alarm is only triggered when both PIR and microwave layers of detection detect motion.
Two independent left and right detection areas
In low mount configuration, the WXS intrusion detection sensors feature two completely independent 90-degree detection areas (left and right), that can be set at different detection distance, sensitivity and trigger independent alarm outputs which is very useful for PTZ activation.
Flexible mounting
The WXS outdoor intrusion sensors can be installed at a low mount providing a flexible detection area from 2.5 to 12m. It can also be mounted at 2.0m high, creating a volumetric detection area with 9m detection range. This option is an effective way to avoid vandalism or masking of the lens.
Built for stability
The WX Shield outdoor intruder sensors are designed to be pet and animal tolerant which means alarms will not trigger if cats, dogs, birds are in the detection area, making it extremely stable. Additionally, the sensors feature OPTEX Super Multi Dimension Analysis (SMDA) which can rule out environmental changes such as swaying vegetation, shadows etc. making the sensor very reliable.

180° panoramic PIR detection.
Adjustable range 2.5 – 12 m (8 – 40 ft) per side (Low mount).
High mount: Fixed at 9 m (30 ft).
Independent left/right side adjustment.
Wired models (AM/DAM): 9.5 – 18 V DC, ~23–24 mA at 12 V DC.
Wireless models (RAM/RDAM): 3 – 3.6 V lithium batteries (CR123A, CR2, or ½AA).
Typical life: 2–5 years, depending on battery type, LED usage, and anti-masking.
Blinking red (~60 sec): Warm-up.
Solid red (2 sec): Alarm triggered.
Blinking red (3× repeat): Masking detection (AM/DAM/RAM/RDAM).
Solid yellow (2 sec): Microwave detection (DAM/RDAM only).
High mount only: Red blinking when tamper switch is triggered.
Low mount: 0.8 – 1.2 m (2′7″ – 4′). Recommended 1.0 m.

Close the cover — unit enters walk test mode automatically.
LED lights for 2 sec when detection occurs.
Test mode ends after 3 min (LED blinks for 5 sec).
Power up the sensor as normal and close the cover. When the cover is on, an automatic walk-test function is enabled. After 3 minutes, the sensor will flash quickly for 5 seconds to indicate that the walk test is going to expire.
PIR sensitivity: High / Medium / Low (per side).
Microwave (DAM/RDAM): Short / Long.
PIR/MW immunity: Normal / High (reduces false alarms).
