People Counting - The Sensors

CENS Systems offer a variety of people counting methods to ensure the right solution for any environment

Radio Beam

The Radio Beam People Counters will operate under all weather conditions, including heavy rain and snow, and will give accurate counts. The counter consists of a radio transmitter and receiver, and operates by detecting the change in radio signal as a person walks between them. The counter is very adaptable and can be used for counting walkers, skiers, snowmobiles, cars etc. The transmitter and receiver can be set up to 8 metres apart (25 metres for the long distance unit) and can therefore be positioned far back from the path so that they cannot be seen. The counter has very low battery consumption and a PP3 size battery will last for up to 200 days. The unit is very easy to set up, as there is no cable between the two units. The sensor has a narrow beam and can therefore discriminate between individuals in groups if the unit is positioned where walkers normally walk in single file. The radio beam passes through thin wood and plastic so that the counter can be hidden behind signs etc

• NEW TECHNOLOGY
• HIGH RELIABILITY UNDER ALL WEATHER CONDITIONS
• COUNTS PEOPLE, HORSES, SKIERS, CARS and CYCLISTS etc.
• LOW BATTERY CONSUMPTION
• ALL WEATHER OPERATION
• VERY LONG SENSING DISTANCE
• EASY TO HIDE AS BEAM PASSES THROUGH WOOD AND PLASTIC
  

Pressure Mats

Buried PVC pressure slab sensors can be used in most types of path except bedrock and thin soil. When carefully installed they are almost impossible for the public to discover. The slab is buried in a 10cm deep hole on level sand and then covered over with the original path surface material. The standard size is 50cm wide by 60cm long and 16mm thick. A smaller size suits mountain bike singletrack routes and a larger size suits wider paths where people still have to walk in single file. Several slabs can also be installed side-by-side across very wide paths so that walkers moving side-by-side are counted correctly in pairs, triples etc.

Gate Counters

Gates come in all shapes and sizes and materials. Usually each one has to be considered as a special case. It may be possible to bury a slab within a small kissing gate to get an accurate visitor count but often a magnet is used to count the number of times the gate is operated rather than the number of people going through it. Some types of gates also suit pyro sensors hidden in one of the upright posts. For some gates it may be better to utilise an adjacent path.
