But I'm very willing to believe landlords perceive a benefit from increased surveillance of their renters. I dunno why you would single these out (I'm assuming you mean the RFID setups they have on most new apartment buildings?). seems like they pretty obviously increase security over everyone having a common mechanical key to the main door. makes it way less of an issue when someone loses a key and/or moves out; you just deauthorize their code. once you give a couple hundred people the key to the front door, you either give up entirely on having the main entrance be secure, or you have to replace the lock and hundreds of keys over and over again.
