Invest in this....(StrikeMaster 2 Door Frame and Hinge reinforcement).
Secondly ask your apartment manager if you can install a security door (probably not). Also ask if you can install a superior deadbolt in your door as opposed to the @%*++!%* one your %!#!%*% apartment ownership installed (they're all $!+**@$+) to save money. Also ask if you can replace interior doors with more solid, non-hollow core doors (metal or wooden).
Also cover your windows with 3M Security Window tint.
Ask your apartment manager if you can install interior burglary window bars inside your apartment.
Invest in one of these for patio sliding doors (master lock window and patio door lock with alarm). Also have 3M Security Window tint installed on the sliding doors if they also have glass.
Itemize ALL your valuables, talk to your insurance company. Be thorough, make sure they take all your needs/items needs into consideration in regards to your policy.
If your apartment allows it, buy a dog (preferably a pit, German Shepard, Rotty etc). If they're breed restrictive it's okay get one anyways as most burglars don't want to deal with that.
If you can afford it invest in an alarm system (ADT for example), make sure you get a permit for your alarm system or else expect a lofty bill from the city if local law enforcement ever has to respond to an alert.
Invest in a firearm and become properly trained in using it/maintaining it.
G'luck, burglary is no joke. Never lie down and let someone take yours, ever.
