TMAS uses overhead video camera to capture a head count (literally), which we find to be significantly more effective than a typical door counter, which struggles with strollers and clumps of people (e.g. families that walk in lock step).
Their customer support is phenomenal, working with us to tweak the angles for optimal readings. Don't let the fact that they're in Canada weigh in the decision. They sent a local installer and have worked remotely to make this work so well for us! Also, it's very affordable! Review collected by and hosted on G2.com.
Nothing to dislike. I had worried about distance for maintenance, but that wasn't an issue at all. Review collected by and hosted on G2.com.
