Much as I would like to set man-traps I reckon the law would be on the other side. Absolutely every security method I have studied on here and elsewhere ultimately has a defeat. We must not underestimate the criminal mind, it is intelligent and learns how to eventually beat new stuff which becomes available. I realised this when I showed the LR technician the damaged sounder which the toe rags left behind when they made their exit; he said he had never previously seen one recovered from crooked defenders he works on. Makes me think the crims are using them to learn and teach others in their gangs. I have a few ideas to put extra layers of defence up, any that I come up with I will share. At this time the criminals have the knowledge and equipment to disable the alarms, access the vehicle, plug in an OBD key coder and drive off. Bit of food for thought?
