![]() This positioning provides a broader field of view, allowing the sensor to monitor a larger area. By positioning motion sensors in these locations, you ensure comprehensive coverage and accurate detection of movement, minimizing blind spots and false alarms.Ĭorner of a Room: Another effective placement for motion sensors is in the corner of a room. These areas typically include hallways, entryways, and corridors where people frequently move. High Traffic Areas: Placing motion sensors in high traffic areas is a key strategy for optimal performance. Both sensors must be triggered to sound an alarm, but this does not guarantee the absence of false alarms. They cover a larger area compared to an infrared sensor but are more expensive and can be susceptible to electrical interference.ĭual Technology (DT): Dual Technology sensors utilize both microwave and passive infrared technology to achieve a further reduction in false alarms. Microwave (MW): Microwave sensors transmit microwave pulses to detect motion by measuring the reflection off a moving object. Users can program the sensitivity level from low to high for greater accuracy and reduced false detection They save power by not continuously sending signals to detect motion and are popular in commercial applications due to their affordability, durability, and suitability. Passive Infrared (PIR): PIR motion sensors use passive infrared technology to detect motion from people or moving objects by measuring temperature fluctuations. In some cases, the nature of the item means that it is non-returnable, for example, due to hygiene/health and personal care/wellness/consumable nature of the product.There are three distinct types of motion sensors available for various applications: Office Products and Wireless Returns Policy New electronic items fulfilled by Amazon AU can be returned for change of mind, for a replacement or a full refund of the purchase cost of the item within 30 days of receipt of delivery.For information about returning faulty electronics please see Returning Faulty Items.
