Metal thieves are here to stay (literally in most cases) and not much can be done in areas with limited police numbers .
Perhaps better to look at security .
The obvious is to have a well thought out system of security alarms , locks and registered key holders for clubs .
Less obvious would be application of modern anti-theft and tracing technology . It is for instance possible to do these things :
Invisibly mark a boiler , engine , tool or raw material with a unique code .
Fit anti-theft and tracing chips , collars and tags . Shops have a very simple system of anti theft labels .These have a passive device on goods and a shop door detector . Cars have anti theft devices and some have full track and trace on moving car .
Have an alarm which is triggered when metal is simply moved .
Have silent alarms with radio or telephone based owner and police call out .
Notes:
All the tag and tracking devices need an activate – deactivate control which is easy for legitimate owners to use but almost impossible for thieves . Car immobiiser devices would work as would some types of fail after x tries alphameric punchcode devices .
For some applications the link wire alarms seen in model shows would be much better than nothing – especially if connected to a very loud and irritating alarm .
