I rolled mine into the house and contents. Covered at home, in car and at cabin at caravan-park. Please note, my insurance covers my home and cabin as principal and secondary place of residence and contents for both so the deal is OK. (The cabin is a basic fire, theft and liability on a $15,000 cabin so its cheap anyway. If it floods we are all stuffed - well above any recorded flood level). Rang the 'over 50s' group for a quote and then haggled with my current insurer C'wealth. My point is that I simply shopped around and ended up with the current bank insurer.
Couple of provisos - main home monitored alarm, security shutters, postcode below Melb average for break-ins and detectors are stored in a fixed locked steal cabinet.
At cabin, stored in a fixed locked steal trunk. The cabin post-code is actually worse than my Melb one for % break-ins in the closest town - go figure.
Sorry i can't be more specific but the detectors can be insured at the three points - home, car and second residence even if its a rental or motel etc. Cameras and laptop were the same deal.
