I sat down with John Marco, Director of Marketing for Optex, a company known for its motion detector technology – the newest of which uses LiDAR. By adding intelligence to how these values are programmed, the days of the security technician “walk test” to determine the detection area may be numbered. The advantage of LiDAR in this application is how finely the detection area and target object size can be tuned, and how well a target can be tracked. Once a static scene is established, changes to that scene can trigger a motion alarm. By measuring the light from the laser’s reflection, 3-D representations of surfaces can be created. Popularized by the autonomous vehicle industry and smartphone manufacturers, LiDAR uses a pulsed laser to calculate the distance from the laser source to an object. The Next Step: LiDARįast forward to today, and companies at the forefront of motion detection have been implementing a new technology: Light Detection and Ranging (LiDAR). Both sensors would need to be activated before an alarm is triggered. Passive infrared, for example, is commonly paired with microwave detection. Many motion detectors use multiple technologies in one in an effort to reduce false alarms. Microwave detectors operate on the same principle of the original ultrasonic devices – microwave pulses are sent out and the device measures the reflections back, looking for changes. Passive versions of these detectors have no emitters instead, they use sensors to detect the difference in infrared emitted by objects in range. Active infrared sensors work by emitting infrared radiation, detecting differences in temperature between an object and its surroundings. In the 1980s, advancements in technology brought us the infrared motion sensor. By the 1970s, these motion detectors were popular components in home burglar alarm systems however, their technology made them prone to false alarms, as the ultrasonic waves could easily be disrupted by innocent disruptors such as wind or a clock chime. Using his military knowledge of radar, Bagno developed a device that used ultrasonic waves and the Doppler effect to detect motion in a room. The first motion sensor was invented in the 1940s by Samuel Bagno using technology that was developed during World War II. That said, while the technology has certainly evolved over the years, it has not necessarily kept pace with the advancements that have been made in video surveillance or access control, for example.Īt least one firm is looking to spur this evolution more quickly, with a goal of reinventing the motion detector as a smarter device with broader applications – elevating its position to an edge device with connectivity, programmability, and intelligence. They are purpose-built devices with a single-purpose application, and they usually perform well. Motion detectors have long been key tools in a security designer’s toolbox however, they are also often the subject of nuisance alarms and installer frustration.
