Hi
We have 3 separate workshops and an office building leading from a shared and open access servicevyard. Recently we've had a couple of incidents where we have caught strangers in one of the workshops, probably looking for tools etc. When we've caught them they make their excuses so there is no point calling the Police because they haven't committed a crime.
What I want to do it install a simple access control system where one card or fob can get into every building. Something easy to install and cheap. We don't need an expensive computer system,. Any recommendations ?
Thanks J
