When you start doing your research to buy a security camera, you are likely to come across some ratings like IP66, which the outdoor cameras are usually branded with. If you wish to delve deeper into this topic and wish to know the real meaning of the IP rating of the security cameras and how strong they are in protecting the systems from a security breach, then you have stumbled upon at the right place.
What Does IP Actually Refer To?
For the uninitiated ones, IP means Ingress Protection, which is one of the main factors for measuring up to which extent the outdoor camera is protected from the outside atmosphere and weathers. To begin with, IP rating is basically made of two numbers out of which the initial number is used to check how much the camera is being protected from dust, while the second number indicates to what extent the camera can be protected from water or other liquids when it is installed outdoors.
Since IP rating majorly depends on two factors – that is majorly dust and liquid, the rating fluctuates on the basis of the protection level the camera is receiving in order to function properly in adverse conditions as well.
IP Rating Calculated on the Basis of Dust
If you happen to check the IP rating on the basis of dust, then the primary number that can help you determine the protection level is the first number in the IP rating. For example, in IP65, 6 is the rating allotted for dust protection. Usually, the range of dust protection ranges from 0 to 6. This is how the dust protection can be calculated on the basis of the number.
- 0 rating: No protection from dust and is vulnerable to damage due to dust.
- 1 rating: Can protect the camera from solid objects, which are above 50 mm in size
- 2 rating: Can successfully protect the camera from solid objects ranging over 12 mm in size.
- 3 rating: Can protect the camera from solid objects over 2.5 mm.
- 4 rating: Can protect the camera from solid objects over 1 mm.
- 5 rating: Can provide limited protection from small particulate matters like dust.
- 6 rating: Can provide complete protection from dust.
Hence, the higher the rating, the better is the protection. This, in turn, helps in proper monitoring of the outdoor area where it is installed.
IP Rating Calculated on the Basis of Liquid
IP rating of the liquid protection usually ranges from 0 to 8. The calculation on the basis of the rating is described below.
- 0 rating: Zero protection from liquid.
- 1 rating: Can be protected from dripping water, which is falling vertically on the surface.
- 2 rating: Can be protected from frequent sprays of water tilted up to 15 degrees in vertical direction.
- 3 rating: Can be protected from frequent sprays of water tilted up to 60 degrees in vertical direction.
- 4 rating: Can be protected from frequent sprays of water in all directions.
- 5 rating: Can be protected from jets of water oozing out in low pressure almost from every direction.
- 6 rating: Can be protected from jets of water oozing out in high pressure almost from every direction.
- 7 rating: Waterproof protection even if immersed in water for some time.
- 8 rating: Capable of working even if immersed in water for a longer duration
Depending on the rating, you can install the IP security cameras at designated places for optimal protection and vigilance at all times.
