A radar sensor that authorises opening. This anyone can do.
But a radar sensor that identifies incorrect transit.... This requires a bit more technology, and not everyone can do it.
Two sensors that authorise opening. This only a few can do.
But we can do all these things. Some things though we would rather not do, because we know they won't work.
Others we will happily do, as we know they will make all the difference. The difference between us and them - between who is willing to reason with the clients to find a solution to their problem, and those who will say yes to anything but then their solution won't work. Sometimes you just have to say no.
Radar sensors are "sensitive" and don't work in all situations. Let us tell you why.
