What IP67 actually means
The two digits are separate tests. The first is solids, the second is water, and a higher number is not automatically better for your situation.
The 6 means dust-tight: nothing gets in, over an eight-hour test. The 7 means the unit survives being submerged in a metre of water for half an hour. That is a laboratory test on a new unit, not a promise about a camera that has been on a wall through three monsoons.
What fails in practice is almost never the camera body. It is the cable joint, where the network lead meets the pigtail. Weatherproof that joint properly — a gland or a sealed junction box, not tape — and an IP67 camera lasts. Leave it exposed and the rating on the box is irrelevant.
Under an eave with a real overhang, IP66 is plenty. On an open wall or a pole, buy IP67 and seal the joint.
