It is important to know how many people visit your exhibitions. By mounting sensors or switches at appropriate places in your gallery or museum you can keep track of the days and times your visitors arrived and left.
A standard installation of WinCounter with a doorway sensor allows you to keep track of visitors. Use the reporting module to produce reports of visitor numbers on certain days and find out which times of the day are your busy or quiet times.
You can use portable wireless sensors to count visitors to special exhibits. Careful placement of an appropriate sensor can give accurate results of foot traffic past your exhibit. If you only want to see relative counts at different times of the day then a lower priced sensor would be sufficient. If you want a more accurate count then a carefully placed beam sensor or a turnstile arrangement with a switch or beam would be more appropriate.
For one off ad-hoc counting you may consider issuing staff with hand held wireless keychain switches that they can use to keep a tally of up to three different events.
