Hi,
I want to rent an appartment by the week and I need to conceive a pretty neat setup to let people in.
I want to have a keypad on the exterior door connected to an door access controller.
I then hook up a PC to the controller and feed access codes automatically to it with a program on the computer (probably a linux box) through a serial RS-232 interface.
Do anybody know of a cheap setup that could do this. I only found big solutions for business use (meaning access controllers that handle holidays, 500 codes and up, etc.) I just need to feed it a couple of codes (5 max). The computer would update the access controller's list of codes. I would like also to handle start dates and expiry dates on certain access codes.
I found access controllers that cost 200$ US and keypads that cost 300$ US + electronic strike that cost 300$US.
I once worked with Kantech equipement at a former employer and it did what I want but I remember how all that cost to my boss.
Are there residential grade components out there?
