Mounting OPTEX sensors at their optimum height

In order to get the best performance from OPTEX outdoors sensors, considering the correct mounting height is crucial.

Low-mount sensors

OPTEX low-mount volumetric sensors, the 90-degree VXI, VXS and 180-degree WXI should be mounted at 0.8 to 1.2m from the ground. They are ideal sensors to detect intrusion in a clear area – where no structure or outdoor furniture obstruct the detection layers and create a blind spot behind the structure, and where small to medium size animals, such as cats, dogs and foxes may walk in the detection area.

If the sensor is mounted below the recommended height it would mean the two detection layers are getting too closed and the animal tolerance will decrease. Taking the example of the dog on the diagram below, if the sensor is mounted too low the dog will trigger the alarm.

High-mount sensors

OPTEX’s volumetric high-mount sensors, the LX-402 and HX series, enables detection of an open area even if there are some obstacles. For instance, when protecting a driveway, it can still detect movements around a parked car.

Multi-height sensors

OPTEX also has a range of sensors that can cater to both low and high-mount. Our multi-height sensors are the WXS and QXI.

The WXS can be mounted between 0.8m-1.2m in low mount, or at two metres in high-mount. This can be effective in avoiding vandalism or masking of the lens. In high-mount position, the detection is fixed at 9m and the settings need to be changed as highlighted in this video
