Question about buying a car security system

Ok , well I want to buy a security system for my car but I dont know what to have on the system. I would like keyless entry, and I heard theres some digital screen that you put on your keychain that shows if someone makes vibration around your car or if someone breaks glass. and other stuff like that. Can anyone tell me what all the proper names for the features you can have put into a security system and how the amount of channels plays in with all this..

Also what is the best security system out there that anyone can recommend that will be able to have lots of features on it.

There was at least one other recent thread on this forum asking for brand recommendations and an explanation of the benefit of multiple channels. Please try searching this forum for that thread.

As for the LCD remote, you are looking for the 2-way paging remote. These often are only available with the FM systems, which seems reasonable since to have the range to make them practical, you really need to have the FM system.
