Description
AJAX OPTEX HX-40RAM: High-Mount Precision Outdoor Security
Take your perimeter protection to the next level with the AJAX OPTEX HX-40RAM. This high-performance, battery-powered outdoor PIR detector is specifically designed for high-mount installation (2.5m–3.0m). By mounting the device higher, you gain a superior vantage point that is difficult for intruders to reach or tamper with, while maintaining an expansive detection field
Equipped with an integrated AJAX Transmitter (TX), this unit provides the legendary stability of Optex hardware with the seamless, encrypted wireless connectivity of the AJAX ecosystem.
Key Features & Benefits
-
Advanced High-Mount Detection: Engineered to be installed at heights of up to 3 meters, providing a broad “top-down” view that effectively covers large yards or driveways.
-
Active Anti-Masking (AM): Superior IR technology detects if the lens has been covered, painted, or obstructed. If an intruder attempts to “blind” the sensor, an instant notification is sent to your AJAX app.
-
Dual PIR Technology: Uses two layers of PIR detection (upper and lower). An alarm is only triggered when both layers are breached, virtually eliminating false alarms from small animals, swaying grass, or shadows.
-
Intelligent Summer Logic: Automatically adjusts sensitivity during high-temperature days when the background temperature is close to the human body temperature, ensuring consistent detection year-round.
-
Seamless AJAX Integration: Includes the AJAX TX pre-fitted, allowing for long-range Jeweller communication, remote configuration, and real-time battery monitoring via your smartphone.

Why Choose the HX-40RAM?
The HX-40RAM is the professional’s choice for complex outdoor environments. While low-mount sensors are great for pet immunity, high-mount sensors like the HX-40RAM offer better protection against vandalism and provide a cleaner “line of sight” over obstacles like parked cars or garden furniture. Its Vegetation Sway Analysis further ensures that wind-blown bushes won’t trigger unnecessary alerts.
