Hi hope you can help. So the property has polystyrene insulation walls mounted to the exterior. Im wanting to mount a cctv camera to it with a good fixing and without having to fix right back to the pebble dash walling behind as that would be too much work. The camera doesn't way a lot approx 680g
Is there any fixings that grip well into polystyrene insulation blocks?
Picture in attachments as reference
Thanks
