Team, I am looking for a simple way to signify if one of our 8 doors are either opened or unlocked without having to visit each door location. I would like this to be accomplished via wireless communication from a wireless switch of some sort (located at each door) to a wireless wall panel (located at the primary entrance/exit point) so that the last person leaving the building can simply look at the panel and see if any of the 8 doors are open or unlocked without having to visit each door location. I appreciate any feedback.

The open of course is the easy part, any basic wireless security system can do that. For the lock and the unlocked, you would need electric locking system on each door. Still not hard, just a little pricey
