Good news
A product is about to come onto the market which combines the fuctionality of blackjax with a gsm pager and tracking system.
This is what happens....
Say your car is stolen from your house by a thief who gets a hold of the keys...
you simply send the vehicle a short sms to activate the system. This starts the following sequence..
1:- siren gives 3 short bleeps to warn driver that immobilisation is about to commence.
2:- after a short pause the brake lights start flashing to warn vehicle following that the car is coming to a halt.
3:- the next time the vehicles engine speed comes to about 1000-2000 rpm, the engine is shut down and the systems siren starts sounding. * 2 sirens can be fitted.. one internal "painmaker" which makes it difficult to drive or stay in the vehicle. One external to draw attention to the vehicle.
Once the siren has been activated a text is sent to the owners phone and they can then request the vehicles resting position via a short sms.
When the owner returns to the vehicle he can disarm the system by entering the pin code via a switch hidden in the vehicle AND send the deactivation message via a short text message.
The car is then returned to normal and can be driven using the normal key.
No Subscription Costs
The system uses a Pay-as-you-go sim card so you only pay for what you use..
more details when i get them..
