Ajax DualCurtain Outdoor: Two-Way Curtain-Type Outdoor Sensor

Protect the perimeter of the property.

Note: This device requires a Hub Plus, Hub 2, or Hub 2 Plus to operate (frequency 921-922Mhz).
DualCurtain Outdoor It helps control security around your perimeter without obstructing people inside. Two independent optical systems with narrow viewing areas and flexible customization allow for precise detection up to 30 meters, while eliminating factors that could cause false alarms. Proprietary ELSA (Extended Live Signal Analysis) software reacts quickly to intruders and eliminates natural distractions or pets.

Precise down to the smallest technical detail.

The two sensors are equipped with two separate optical systems, each consisting of two PIR sensors with a narrow field of view. Thanks to the mechanism Temperature compensation ensures consistently accurate detection even in changing environments. Signals from the sensors are processed using ELSA numerical algorithm latest. Only when two sensors in the same system human motion detection At the same time , the new device activates the alarm.

Effective in the area near the device.

DualCurtain Outdoor features technology that expands the protection zone in the near area, something most outdoor curtain sensors lack. When Near Area Detection mode is enabled, the upper PIR sensor gains an additional narrow viewing zone angled downwards at 40 degrees relative to the main area. This feature allows both sensors to simultaneously detect movement when someone approaches the device, effectively eliminating blind spots – a common problem with this type of device.

This mode is ideal for protecting windows or doorways that pets cannot access. However, because the detection zones are so close together, the effectiveness of pet exclusion will be reduced in these areas.
