An international protection code (or I.P. code as it is commonly referred to) is the marking which classifies how much protection a product has against various forms of intrusion.
In terms of a waterproof inspection camera, the I.P. code indicates how much contact with water or liquid the device can endure.
Without this information, the user might cause unnecessary damage to the camera head by submerging it too far under water.
An I.P. code consists of the letters ‘IP’ followed by two numbers (in some cases an optional letter also follows the numbers).
The first number refers to the level of protection against solids, for example dust and grit.
The second number refers to the level of protection against liquids, such as water.
For example, if a waterproof inspection camera has the code IP67 on it, the number 7 tells the user on how much liquid the device can withstand.
Each model of inspection camera may have a different level of protection. This information will be specified in the product handbook by the manufacturer, so always check the I.P. code before use.
Below is a table showing the standard level of protection against liquid that each number represents.
