Optex BXS-RAM Intruder detector

The BX Shield is a series of curtain outdoor motion sensors with up to 12m detection range on each side. Ideal for the detection of people in the immediate boundary of your home or office building, the outdoor detectors feature four PIRs, two on each side. The left and right detection area can be set up completely independently from each other. The BXS-RAM is the wireless bi-colour model with anti-masking. 

Independent left/ right motion detection

The outdoor motion sensor’s detection range, sensibility and alarm output can be set independently on the left and the right. The detection distance can easily be set at 2.5m, 3.5m, 6m, 8.5m to 12m on each side, and the sensitivity can be set from low to extremely high, detecting as small a difference in temperature as 1 degree Celsius. The BX Shield can be easily connected to a fixed dome CCTV camera to send a visual alarm when people enter the immediate boundary of the premises.

Versatile design 

The BX Shield curtain sensor has been designed with the user in mind. A 90-degree unlocking system allows easy access to the settings area, while a spirit level helps to fix the sensor on straight. Black and silver face covers are available, enabling the outdoor curtain sensor to blend into its environment.

Four PIRs in one sensor

Why two PIR in each side? - To offer the best performance needed in an outdoor environment. On each side, the BX Shield motion sensor features two passive infrared beams; one pointing towards the floor and one pointing away from the sensor. Both beams need to trigger to confirm the detection. This system will ignore small to medium-sized animals such as dogs and detect only people.
