factory alarm
How is the factory Alarm system on these cars. I know in general factory alarms are worthless, but are these any better due to the car costing so much. Thanks

The 997 has an electronic ignition lock and an electromechanical steering column lock for increased anti-theft protection. Individual components cannot be replaced without the use of special testers and access codes belonging to the vehicle.
Once the key is inserted in the ignition, the data is read out via an inductive radio link. It is encrypted and transmitted to the driving authorisation control system, where it is evaluated.
communication is established with the electromechanical steering column lock and another exchange of encrypted data takes place with the driving authorisation system. The steering column is unlocked if the key is positively identified.
The anti-theft protection system is essentially the same as in the previous model, however it does have some new features which are described in brief below.
Interior surveillance is now executed using a radar sensor instead of an infrared sensor.
The alarm contact for the storage bin in the center console is no longer required since the bin is now linked in to the central locking system.
As well as unlocking via remote control, the car can also be unlocked via the door lock cylinder. This mechanically opens the driver's door. It does not, however, deactivate the anti-theft alarm system, just interior surveillance and the door contact on the driver's side. If the ignition key is not inserted and successfully identified using the transponder housed in the key within 15 seconds, the alarm will be triggered.
If someone wants your car they will have to tow it away or steal your key.

but how is it as far as keeping people from breaking in and stealing your stuff. I'm guessing since it has the survellience and all its pretty good. Would it be worth it to put a viper in.
