"The VXI series is our best selling outdoor intrusion detection sensor range. It provides a very reliable approach detection with a range of up to 12m for residential and commercial applications. The sensor which should be mounted at ca 1.2m height includes two PIRs providing a double layered detection area, the sensor will only trigger when both layers are activated. The VXI sensors feature digital analysis to exclude causes of false alarm, they are weather resistant (IP55 rated) and have double conductive shielding to reduce the impact of sunlight. The VXI-AM is the hardwired model with antimasking.
The VXI sensors features a digital microprocessor which analyses the infrared emissions received and differentiate the ones generated by human from the ones generated by sunlight, animals, vegetation sway, or weather conditions. This intelligence makes the risk of false alarm very low.
The detection length of the VXI sensors can be set to 12m, 8.5m, 6m, 5.5m or 2.5m to adapt to the site configuration. The sensor comes as well with a choice of pre-cut masking templates to modify the detection areas and only focus on the points of interest."
