Bike home security/tagging

[seadragon]

Having my shed burgled over the weekend has made me panic about my 3 bikes sitting ‘on show’ in the conservatory. My lovely petrol mower was stolen and other houses were burgled too, well sheds anyway, stuff like motorbikes, mowers, garden tools etc, so I guess some kind of a raid late on Saturday night.

I would please like some advice on security as I love my bikes, but they are also pretty rare/hard to find and I would be distraught if they were gone, never to be seen again.

I have 2 thick bike chains for locking up scooters/motorbikes etc but haven’t used them yet, PJB I think the make is called and they both come with a moon/disc lock (bought them online from Sanderson Security).

They won’t be much help however though if someone picks up the bikes and carries them out. I ideally need some anchor in the floor, but if I suggest drilling and sinking an Abus floor anchor into the wall or floor of the conservatory my fiancé is going to go spare, not even an option !!!

Basically have 2 questions:

1) Any suggestion on how I could secure my 3 bikes indoors?
2) What tagging devices are out there in case they do get stolen? I did try the I.S.R. product on a previous bike but wasn’t too impressed but I was wondering what else was out there for my bikes and maybe other valuable stuff in the house too, maybe something that shows under U.V?

Thanks in advance, any advice much appreciated.

I'd be interested in replies to this, I am paranoid about my bikes!
