Synology Surveillance Station - Building Access

I’m installing a Synology Surveillance Station for a client that has a hodge-podge of security and building access control.

Currently, they have two separate keypads that control maglocks. The codes are programmed into the keypads.

They would like to centralize this from a single program, if possible. I know there is stuff out there, but I’m not sure what to search on. I’m coming up empty so far. What I would LOVE to have is a program that can run on the Synology.

Can anyone give me any advice? I’m looking for info on software and compatible keypads.

Thanks in advance!
