I had an older friend from church who after serving as a decorated Marine in WWII became the crime scene photographer for the county sheriff's department. I had some occasion to visit him at home and noticed right away a security system sticker and keypad. His wife met me at the door and invited me to in and to go straight to the basement while suggesting that I'd be there awhile. Sure enough the entire basement was dedicated to photography complete with darkroom, tens of thousands of feet of film, thousands of rolls of worth of negatives, and mostly display cases of hundreds of all kinds/styles of cameras, ancient flash bulbs, even his old Marine dress uniform on a manikin. It took over an hour for the 'quick' tour that he valued at $250,000 (20 years ago) and he indicated that the best stuff was elsewhere as he couldn't afford the insurance (even with a home security system) to keep it there. After retirement and 4 open heart surgeries he could no longer lift a 35 mm SLR he still shot using disposables, did darkroom restoration work, and consulted with the state historic museum on preservation of their collections. His Marine/sheriff department honor guard funeral was moving and stunning.
