After vandals got into our spare garage and damaged my partner’s Velomobile, i am looking for some kind of alarm for deterrent.
Situation is:
400 metres from our home
Garages opposite a boarded up house with no view to the outside road
No electricity
Very little habitation around (one would expect no one to overhear or even see people)
Up-and-over garage door has no lock
We relied on the unlikelihood of anyone nosing around but the whole garages area was steamed by these vandals who then set fire to the farmer’s straw barn. Lots of things were damaged, the Velomobile is a tiny fraction of the overall damages.
I though about a battery-operated remote control siren but we would have to fit it somewhere where visitors could not immediately kill it. Garage is just a bare concrete box. Siren would hopefully frighten them off, but if they think it through they might realise it is unlikely anyone would hear them. How loud should a siren be anyway?
Anyone have any suggestions?
