QXI is an outdoor 120° intrusion detector range for wide-angle approach protection around residential and commercial buildings.
The series provides up to 12m detection, helping protect gardens, driveways, patios, balconies, courtyards, building approaches and open external areas. With wired, wireless, PIR and dual-technology models. The QXI offers a customisable mounting height detection solution depending on the application. Whether residential or commercial the QXI can be used as a high mount sensor (2.2 - 2.7 m (7' 3" - 8'11") or low mount sensor to create a "pet alley" (0.8 - 1.2 m (2' 7" - 4').
Stable outdoor performance
The QXI features two layers of detections (QUAD pyro elements) and operates with AND logic. In high mount applications, this provides a good tolerance to small animals, contributing to reliable outdoor detection.
Flexible mounting height
When mounted between 2.2 and 2.7m the sensor creates a multi-level volumetric detection pattern, allowing it to ignore small animals. In environments with larger animals, the sensor can be mounted between 0.8 and 1.2m height, to provide a pet alley.
Wide angle detection
QXI provides 120° outdoor intrusion detection for wide approach areas around residential and commercial buildings. Its broad coverage makes it suited to gardens, driveways, building approaches, entrances and open areas where a wider field of detection is required.
The QXI PIR sensor detects changes in infrared radiation within its field of view. All objects emit infrared radiation, and the sensor is designed to detect variations that occur when a person or an object moves within its detection area. The QXI uses a dual-element pyroelectric sensor to improve detection accuracy. This type of sensor can distinguish between the gradual changes in infrared radiation caused by environmental factors (like temperature changes) and the rapid changes caused by human movement.
The QXI offers models that combine PIR with microwave technology, thus creating a dual tech sensor. PIR and microwave algorithms provide the ultimate stability in detection performance as the alarm is only triggered when motion is detected by both the PIR and microwave technologies.

FAQ
Masking strips are supplied with the QXI in the box. You can mask individual sections of the detection area by placing the corresponding strip to the lens. The latches that hold the lens in place can be found at the top, bottom, left and right of the lens. The lens can be removed easily by unlocking each latch with your thumb or screwdriver and gently push the lens out. Please ensure that you place the masking strips on the inside of the lens, not on the outside.
The battery-operated models of the QXI (QXI-R, QXI-RDT) have back-boxes that are large enough to accommodate most transmitters. The maximum size of the transmitters should be: 90mm (length) x 50mm (width) x 30mm (depth). The backbox of the QXI have sticking mounting pads inside to secure the transmitter in place.
Anti-blocking is a feature for the QXI-DT in multi-level mode only. Anti-blocking is used when the detector suspects that it is being blocked by a person or object and will trigger the trouble output. The logic steps are as follows:
- PIR detects first
- Microwave then receives strong signal within 10-30 seconds of the first PIR detection
- No PIR detection within 10-30 seconds
- Trouble signal is generated
The QXI is in multi-level mode by default which accommodates mounting heights between 2.2m – 2.7m. Low mount is for the pet alley function which can be achieved by removing the main unit from the backbox and gently flipping the mirror into the horizontal position. Be aware to not touch the mirror face, only the sides. The mounting height for the pet alley pattern is 0.8m – 1.2m. If the QXI is mounted higher than this and is in the pet alley pattern, that human detection may be compromised. Please note, anti-blocking feature is not available when the QXI is in pet alley mode.
