Warning
The RPM24mm camera and camera kits have two strong neodymium magnets inside them to hold the lids of the cameras on, and we haven't found them to pose any danger.
However, we feel compelled to provide this warning for the magnetic mount because in order for the mount to work, the magnets are close to the outside surface of the camera:
Proper Care and Handling of Neodymium Rare Earth Magnets
Neodymium magnets are extremely strong, and must be handled with care to avoid personal injury. Fingers can get severely pinched by magnets!
The strong magnetic fields of these magnets can damage magnetic media such as floppy disks, credit cards, magnetic I.D. cards, cassette tapes, video tapes and similar items. They can also damage televisions, VCRs, computer monitors and other CRT electronics. Never bring neodymium magnets near any of these items.
Children should not be allowed to handle neodymium magnets as they can be dangerous. Small magnets pose a choking hazard and should never be swallowed or inserted into any part of the body.
Never allow neodymium magnets near a person with a pacemaker or similar medical device. The strong magnetic fields of the magnet can affect the operation of such devices.
Neodymium magnets can inadvertently magnetize other ferrous metals. Keep magnets away from mechanical watches, timers, etc. to avoid damaging them.
Like any tool or toy, neodymium magnets can be fun and useful, but must always be treated with care.
