Any product that is advertised for use outside needs to rate it according to how much weather it can stand, because indoor products, especially indoor video surveillance cameras won’t make it through the first dust or rain storm.
The Ingress Protection ratings consist of two numbers, for example IP 67; the first number will tell you its solid particle or dust protection, and the 2nd will let you know its protection against water.
For dust protection, the numbers available range from 0 or Zero, which has no dust protection, all the way to 6, which is completely sealed against dust and referred to as dust tight. Any indoor camera will have a 0 for its first IP rating, though we have never seen any indoor cameras that have an IP rating.
Any outdoor video camera has worth its salt has a 6 level, which is dust tight. There are some cameras with a 5 at the beginning, which is dust protected, though really should not be used in dusty locations like the Middle East, or the Dust Bowl.
The Available Protections For Solid Object Ingress Is:
- 0: No Protection From The Elements
- 1: Protection Against Particles 50mm Or Larger
- 2: Protection Against Particles 12.5mm Or Larger
- 3: Protection Against Particles 2.5mm Or Larger
- 4: Protection Against Particles 1mm Or Larger
- 5: Dust Protection; Some Dust Will Penetrate Under Sever Conditions
- 6: Dust Tight; No Dust Will Get In This Camera
For water protection, the protection starts at the number 0 for no protection for dripping water protection, all the way to 8, which will protect against Immersion beyond 1 meter.
