Basic security systems are usually installed by the homeowner. This basic security system mostly just uses detectors for doors and windows and triggers an alarm when an intrusion takes place. It's cheap and easy to install. It does no more than sound an alarm to everyone in hearing range if there is an intrusion.
An advanced system is usually set up by a professional. It is an upgrade of the basic system, wherein new detection features are added like motion sensing and glass breakage sensors. On top of that, this system can alert the fire department in case of a fire, deal with other emergencies, and automatically connect and communicate with emergency personnel.
Another important factor when picking a home security system is how fast the response time is. Some companies will pretty up their system with advanced features that may or may not work, so don't focus on that too much. Be sure to get other people's opinions on home security systems.
More money usually means better quality. Don't be blind though; you should still check to see if it's really worth that price tag.
