What the IP Rating on a Camera Actually Means
When looking at video surveillance cameras, you've probably noticed that outdoor cameras get a rating such as IP66 or IP65. You may know that this means the camera is protected from dust and water, but the rating system is much more detailed than that.
To begin, IP stands for Ingress Protection. This is an international standard for measuring what, and how much, a camera is protected from. An IP rating is made up of two numbers - the first number measures the camera's protect from dust, the second measures the protection from liquids.
The rating for dust goes from zero to six, and the higher the number the more protection:
0. No protection
1. Protection from solid objects over 50mm
2. Protection from solid objects over 12mm
3. Protection from solid objects over 2.5mm
4. Protection from solid objects over 1mm
5. Limited protection from dust
6. Complete protection from dust
The rating for liquid protection goes from zero to eight:
0. No protection
1. Protection from dripping vertical water
2. Protection from sprays of water, tilted up to 15 degrees vertically
3. Protection from sprays of water, tilted up to 60 degrees vertically
4. Protection from water sprays from all directions
5. Protection from low pressure jets of water from all directions
6. Protection from strong jets of water from all directions
7. Protected from temporary immersion in water
8. Protected from long-term immersion in water
So if you see a camera with an IP65 rating, you can know it's completely protected from dust and can withstand low-pressure bursts of water. This means the camera would be great for installing outside where it is exposed to the weather and elements.
