I don't know about intrusion detection, but access control systems are very much linux based. There was a startup called OpenPath that used a R-PI (2 or 3 series) and created a custom relay i/o hat. There was a 2 door version that was and is very popular. Motorola bought them out.
Another access control solution that is a little more centralized is Avigilon ACM. Its a ubuntu based x86 image, that is made for Hyper-V and VMWare. The hardware is used with ACM is mercury based.
And finally there is S2. Their access control software is also Ubuntu based.
You can use pretty much any 26-bit weigand reader. OpenPath does offer their own (reader) as an option.
Where its gonna get tricky is the hardware conversion. For example each of these companies (sans openpath) use/can use mercury based hardware, BUT!!!!! Those boards have to be flashed with compatible top secret firmware to prevent tinker people from making their own.
