I use AXIS for both CCTV and Card Access. One "pane of glass" for both systems. They also have IP speaker/PA/Paging systems. IMO, Axis is truly interoperable with other systems. Many of the other manufactures claim to be interoperable but they are not or they require lots of middleware to make them work with other systems.
That is great to hear! I think I have walked 10mi just since I posted. I found that cloud based access systems are monthly fee based so owners will never agree to that. Another is precisely what you mention, the integration of systems. It seems shocking that more don't offer a 'total solution' for common security needs.
It is interesting you mention the IP speaker systems because that is EXACTLY where I am headed. There are known crime problems in the area and cameras do NOT stop crime, they just document it happening, so the cops can do.....nothing. Prevention is on the menu.
But to throw a wrench, we all know bad things happen at night, away from the facility, so having a way to monitor on a phone is key! Bottom line, they want to be able to talk to someone over the PA system on their phone, 100mi away! Maybe even fire all missiles when commanded, via I/O.
Our IT specialist is looking into possible 'build from scratch' solutions, but if the system is networked, there has to be options.
