Delving into IP camera datasheets can leave you lost from understanding. Even after you define what the abbreviations mean, you’re still left wondering the relevance they have to your circumstance. If the importance turns out to be major, then the rating that you require from a camera is your next step.
TriTech Corporation of America put together this guide to help clarify some of the most common and recurrent IP camera technical specifications. These ratings and approvals can also be found with other electronic gadgets and electrical technology, such as cell phones and carpentry tools.

EN/IEC 60529 & ISO 20653
An IP rating is an international standard that identifies protection against solids and liquids by a two-digit evaluation. It is not exclusive to IP technology despite its acronym and will be the code you see most often.
- The first number rates solid protection including dust, tools, and hands on a scale 0-6.
- The second number rates liquid protection on two different scales: ingress and pressure, 0-6K; and immersion, 7-9.
If there is no protection against either type, this is identified by the digit “0.” If there is lack of data for either rating, it is identified by an “X” for the corresponding digit. ISO 20653 applies to cameras designed for road vehicles.
For instance, an IP camera rating at “IP6X” is sealed from dust but, although not evaluated, doesn’t mean liquid protection is nonexistent. Remember: “X” does not mean lack of protection, just lack of supporting data.
The two liquid ratings are separate and need to both be identified, if applicable. The IP code of an IP camera could possibly read “IP66/IP67.”
An IK rating is an international standard that identifies resistance against impact (the force or shock as resulted by a collision). On a scale 01-10 up to 10+5 (10+++++), the test evaluates the energy and measures the joules caused from impact. IK00, if listed, means the camera hardware is not protected under this standard.
One joule is roughly an apple being dropped from the air 3 feet.
IEC 61373/EN 50155
Category / Class
The specification for vibration and shock is given after test compliance. EN 50155 is a standard originally for Railway applications – Electronic equipment used on rolling stock but has since expanded beyond trains. It contains 14 tests with “11 – Vibration, shock, and bump test” as one of the 8 mandatory tests; it refers to clause 12.2.11.
Listed after EN 50155 may be a letter and number indicating the temperature class that the camera was tested in or how it responds to interruptions in the voltage supply.
Temperature Class (F˚)
- S1: no interruptions
- S2: no more than 10 millisecond interruptions
IEC 61373 is a standard originally for Railway applications – Rolling stock equipment – Shock and vibration tests and can be seen as an independent part that’s also a requirement of EN 50155. There are three categories but “Category 1” is the one you’ll see, which means the camera is mounted directly to the shell of a vehicle; under “Category 1,” “Class B” signifies the camera is mounted via housing or case.
There are three tests defined in Sections 8-10: Random vibration – functional, random vibration – long-life, shock.
Sometimes, the two identification codes are used interchangeably; EN 61373 has the possibility of showing up, too.
A NEMA rating is the amount of protection a camera’s enclosure gives in specific environments. In the cold winter of Wisconsin, a camera that’s operational through ice and in below-zero weather may be what you require. Special elements such as fibers, propane, metal and coal dust, or flour could also be a deciding factor.
An ONVIF profile defines the features and abilities of IP cameras, video management software, and related equipment. This is useful if you will have a mix of camera brands and need only one VMS. The requirements within a profile are labeled as mandatory, conditional, or optional.
- S: Common system functions; also applicable to video converters. This includes mandatory video streaming and conditional video format streaming, mandatory encoder configuration, and conditional PTZ commands.
- G: Video data relations; also applicable to video converters and NVRs. This includes mandatory recording, replay control, video search, and event service.
- C: Basic physical access controls; mandatory or conditional by either device or client. This includes door control, access control, and event handling.
