With the integrated AJAX Transmitter (TX) and Active Anti-Masking, this unit delivers the legendary reliability of Optex hardware with the instant, encrypted notification power of the AJAX ecosystem.
Key Features & Benefits
-
180° Ultra-Wide Coverage: A single unit provides a panoramic field of view, eliminating blind spots and reducing the need for multiple sensors on a single facade.
-
Active Anti-Masking (AM): Superior IR technology detects if the sensor lens has been covered, painted over, or obstructed. You receive an immediate alert through the AJAX app if any tampering occurs.
-
Independent Left/Right Adjustments: Customize the detection range (from 2.5m to 12m) and sensitivity independently for the left and right sides. Perfect for masking out a busy sidewalk on one side while maintaining full range on the other.
-
Pet-Friendly Low Mount: Multi-layered detection logic ensures that small animals can roam freely at ground level without triggering the alarm.
-
SMDA Logic (Super Multidimensional Analysis): This intelligent onboard processing distinguishes between human intruders and environmental noise like swaying trees, shadows, or heavy rain.
-
Seamless AJAX Integration: Comes pre-fitted with the AJAX TX, enabling “scan-to-add” pairing with your AJAX Hub and long-range Jeweller wireless communication.

Why Choose the WXI-RAM?
The WXI-RAM is the ultimate choice for wide-open residential or commercial spaces. By offering 180-degree coverage, it replaces two standard 90-degree sensors, making it both cost-effective and aesthetically cleaner. The addition of Anti-Masking makes it suitable for high-security environments where the device might be accessible to the public or potential intruders.
Pro Tip: Use the independent zone configuration to fine-tune your protection. You can effectively “blind” the sensor to a swinging gate or a neighbor’s movement while keeping your own driveway fully secured.
