Protect It
Pack your camera tightly.
Or, to save some money, repack the equipment in its original box and padding.
The original box is great if you stash it inside a backpack or other carry-on.

If its packaging puts force on the lens housing, the delicate threads that connect the two could break.
Pack the body and lens separately using the proper caps on both units.

These caps should be in your original box if you still have it.
Otherwise, you might have to pay an additional fee to check a bag.
Keep It All Together
TSA may require you to scan your camera separately.

However, a TSA agent could request to inspect the camera more closely after the X-ray procedure.

Security personnel might ask you to turn on your camera during screening.

Preserve the Batteries
Don’t carry loose batteries together.

If their terminals come in contact during flight, they could short-circuit and start a fire.
The same goes for contact with some metal, like a coin or keys.
All batteries should be securely and separately stowed during a flight.

Pack batteries so they will not be crushed or punctured.
Chemicals in lithium and Li-ion batteries can be dangerous should their outer casings become compromised.
Turn It Off
Consider taping your DSLR’s power toggle switch into the Off position.
(You might need to use duct tape for strength.)
This step prevents the camera from accidentally turning on inside your bag if you leave the battery attached.
The TSA website maintains a list oflost and foundcontacts for every airport in the U.S.
If you lost your camera somewhere else in the airport, hit up the airport directly.
Agents then re-lock the bag after inspection.
You’ll enjoy your trip more if you’re not worried.
Before purchasing a policy, though, check your homeowner’s insurance; some policies cover such belongings.
