What is the IP rating – IP65, IP66 or IP67 what do they mean

Have you been researching security cameras and come across an IP rating? Then you might be asking, what is the IP rating? What does it mean? Well, I am here to answer these questions and give you an explanation which may help you make your decision on the best security camera or alarm for your needs. Let’s get straight into it.

What is the IP rating?

The IP rating, otherwise known as the IP code, is a standard that has been developed by the International Electrotechnical Commission that defines and measures the degree of protection by enclosures for electrical devices (IEC standard 60529). The ‘IP’ stands for the International Protection marking, or it is sometimes known as the Ingress Protection marking. In other words, the rating describes how well the device is sealed from objects entering the enclosure and how waterproof the device is.

IP codes or ratings are being used more frequently for devices such as mobile phones, tablets, outdoor speakers, and of course, cameras. This is because these devices are increasingly improving their quality, including becoming dustproof and waterproof.

What do the numbers mean?

There is a specific meaning for the numbers that follow IP. The first number indicates the level of protection against solid foreign objects, such as dust. The second number indicates the level of protection against the ingress of water, or in other words, the level of waterproofing.

I have outlined a brief summary of each number and what they mean below.


First Number – Protection against solid foreign objects

  • 0 – Not protectedWhat is the IP rating
  • 1 – Protected against objects of 50mm and greater
  • 2 – Protected against objects of 12.5mm and greater
  • 3 – Protected against objects of 2.5 mm and greater
  • 4 – Protected against objects of 1mm and greater
  • 5 – Dust-protected (however, not completely protected against dust)
  • 6 – Dust-tight


Second Number – Protection against ingress of water

  • 0 – Not protectedWhat is the IP rating
  • 1 – Protected against vertically falling water drops
  • 2 – Protected against vertically falling water drops when enclosure tilted up to 15 degrees
  • 3 – Protected against spraying water
  • 4 – Protected against splashing water
  • 5 – Protected against water jets
  • 6 – Protected against powerful water jets
  • 7 – Protected against the effects of temporary immersion in water
  • 8 – Protected against the effects of continuous immersion in water

As you can see, the higher the numbers, the better the protection. Please only use the above as a guide and refer to the user manual of your device for further information. For example, your device might have a rating that indicates it is protected against the effects of continuous immersion in water, but it could be limited to a specific depth, pressure, or time period.

Of most of the outdoor security cameras I have researched so far, they have had an IP rating between 65 and 67. So applying these figures to the above meanings we get the following:

IP65 – Dust-tight and protected against water jets

IP66 – Dust-tight and protected against powerful water jets

IP67 – Dust-tight and protected against the effects of temporary immersion in water

So that’s it. Even though this is a short post, I hope it gave you all the information you need in regards to the what the IP rating means, and that is is helpful when you need to make a decision on your next purchase.
