Thank you to all who responded regarding door counters. I was asked to share my findings. Quite a few libraries use SenSource. "We use a SenSource TB12 counter. Easy to install. The software used to get reports/data is a bit confusing and clunky. Batteries are expensive and last 6 to 12 months." "Sen Source, Thermal Imaging Master Sensor since October 2013. The unit is over our front doors with a 60 degree lens and Ethernet com port. The library paid $2,064.88 in 2013. The unit send and Excel spread sheet every morning with the total by the hour. I then cut and paste the information into an Excel spread sheet totaling the month and year." “Accurate One” people counter from an Australian company called Total Count. Their website is http://www.total-count.com/ . They are very reliable, easy to install, accurate, etc. Total price with shipping is $227.00, and they arrive in about 10 days. I think I have installed about 6 of them over that past 4-5 years with no problems." -- Stacy Pasche, Assistant Library Director *"Sometimes it's fun to do the impossible." -Walt Disney*
