Night Clubs and Discos have a great need for reliable and versatile counting of patrons. Due to the changing light conditions (strobe lights, flashing colors) and temperature changes (frequent door openings at the entrances) the challenge of getting and keeping an accurate count of patrons is very difficult. In the past most clubs would resort to a manual count kept by a security employee who stands by the door and clicks the count in and out on a handheld device. However, this method is unreliable in the case of a distracted employee or an incident requiring his attention elsewhere in the club. Add in normal human error and fatigue and you can quickly see how an accurate patron count at a busy club is nearly impossible.
Several people counting technologies are available. Stereo vision camera systems, thermal cameras, linear infrared beams, and video analytics are some of the most common technical solutions. All of them have some litmitation as far as lighting conditions, temperature variations, and for counting individuals in large numbers.However, the technology of people counting has evolved greatly in recent years. 3D MLI (modulated light intensity) technology, using the "time of flight" measurement principle is the best solution available and can result in a more than 99% accuracy rate, even in high volume, chaotic conditions, under varying light and temperature conditions.
Using provided software, the counts in and counts out can each be measured, and tallied across several devices covering all entrances/exits. Management can hen view the total room or building population at any given moment. Alerts can be set up to advise management when certain key population levels are reached.
IEE Sensing of Auburn Hills, MI (and Contern, Luxembourg) offers the most advanced solution of this type. Their 3D MLI sensor uses the latest technology, combined with very sophisticated alogorithms embedded on an IP addressable, web accessible overhead mounted device.
