CCTV HLI – Is it just a buzz word?

The concept of integrating CCTV and access control to provide seamless operation has been thrown around for about 4 years now but has it really achieved what was expected?
The term High Level Integration simply means instead of using a piece of wire from every sensing device to tell us something happened on an external system, we are bringing in a data stream on either a RS232, 485 or Ethernet, which is extremely generic. Many tender documents have a statement like “must communicate with the access control system via a HLI”, which could mean anything complies from one alarm action to reporting on every fine detail.
