I'm invited to maintain a very old project with Analog cameras, the communication system used to connect all the other system's devices is called LonWorks.
It seems that the H/W of the LonWork and the Workstations are very old and I've to replace all together with the old VMS.
What do you recommend me using as communication network to control, the IR , external switches , the D/N mode of the cameras ... and what is the best VMS that supports that communication system.
Thanks a lot for all positive sharing and advises.
