In the mean time, I suggest getting these:

http://www.securityprousa.com/dobrwial.html" onclick="window.open(this.href);return false;. Pretty cheap investments that will alert you while you're at home. However, obviously it is not tied to a central system and won't alert the security company which will in turn call the police. It may scare the criminal away, but isn't guaranteed.
Also, look at your lease and ensure that you can add an alarm system. Some apartment complexes will classify adding an alarm system as an alteration. YMMV.
I lived in several apartments the last 6 years (navy moves me a lot), but a few recommendations I have for overall security:
When leaving for an extended period of time:
1. Buy one of these:

Setting a few of them inside your apartment at random times gives the illusion of someone inside. I set the one in my living room at 0500-1000 then again at 1900-0100 and one in my bedroom at 0400-0500 and 0100-0130 so even if I wasn't there, the lights would come on making it look like I was moving from the bedroom to the living room and back.
2. This helped too:

Same illusion as above.
3. Give your car keys to someone you trust or don't park your car at the complex.
Criminals are smarter than we like to give them credit. After all, this is their "job". They will scope the parking lot out and see if cars are idle for a long period of time and will eventually break into your car. (Unfortunately, I didn't do this and my car was broken into - I was on leave for 12 days.)
4. Remove your insurance card and valuables from your vehicle when you leave.
Luckily, when they broke into my car they did not steal my insurance card. (Though they got my tool kit, medical kit, and really nice ray-bans) This has a lot of information on it that can be used to their advantage i.e. your apt address. If they notice your car is idle for a while then most likely they know that you're not at home and steps 1-3 are useless. They will be emboldened knowing no one is home and can break into your place taking their sweet, sweet time.
5. Give your apartment key to someone you trust or ask management to check up on your place every few days.
Some people may not like this, but if a water leak, air conditioner breaks, or whatever happens.. it's better to catch it after a few days vice a few weeks. Depending on what valuables you have or how much you trust said someone or management you might not want to do this. I, however, put most my valuables in my safe and let the insurance company cover the rest.
6. Finally, move out of your apartment. I know for myself, this was easier said than done. However, living in a home that you rent (preferably own =]) has many advantages. From putting in a dedicated alarm system, more space for guns/ammo/prep gear, privacy, etc... you get the picture. It may not be financially feasible at the moment, but having the goal to save for a down payment and eventually getting your own place is rewarding and liberating.
Hope this helped! If you have any more questions or just want some insight just let me know.. I'll provide as much information as I can and I'm sure there are others on here that will gladly contribute =]
