Batman: "I'm Batman" * Allegedly, there are security cameras all over Arkham Asylum, and there are a few places in the game where you can see rooms full of camera screens. Despite this, neither Batman nor Joker seems to take advantage of surveillance devices to find his respective enemy. Instead, Joker is alerted to Batman's presence by the suicide collars on the inmates Batman beats senseless, and Batman just moves from objective to objective without using any of Arkham's security systems to his advantage. * My guess that I'm sure has much supporting evidence: Joker (and/or Riddler's) fiddling probably made it difficult for Bats to hack into the security feed (plus the inmates were probably smashing the majority of cameras they find). And the Joker was more interested in having fun.
