Travel insurance is usually pointless for expensive electronic items like cameras and computers, computers because of low coverage limits and high deductibles, so I have a "personal articles" rider on my renter's insurance policy which covers specific named items (my computer, my camera and lenses, &c.) against almost anything that might happen to them anywhere in the world. I haven't had to make a claim against the insurance (luckily), but it's cheap enough (about $30 $30/year for $3000 worth of items) that I find the peace of mind to be worth it. Talk to the provider of your homeowner's insurance and see what they offer.
