Middleware for DDE

The Disadvantages of a Middleware Integration like Braxos Steward for Destination Dispatch Elevator

| Slower card reads and response from destination dispatch and access control system - poor user experience | | Vendor who integrates with Middleware has no control of the integration | | Another point of failure with another vendor | | More on-premise software to maintain, upgrade and protect from cyber attacks | | More finger pointing when there is an issue | | No real-time visualization of Access Control and DDE Messaging to determine issues and who is responsible | | Often threatens the real-time performance of a system | | Does not integrate with all DDE features | | No ability to use a smartphone to call an elevator and receive a car assignment | | Lack of real-time Visitor Management/Access Control integration | | No ability to remotely diagnose problems | | Too many platforms to be covered |
