What does the IP rating measure regarding electronic devices?

The IP rating, or Ingress Protection rating, specifically measures the degree of protection that an electronic device offers against the intrusion of solid objects (like dust) and liquids (such as water). This rating is essential for understanding how well a device can withstand environmental factors, which is particularly important for devices used in outdoor or harsh conditions.

An IP rating typically consists of two numbers: the first indicates the level of protection against solid particles, where a higher number signifies better resistance, and the second number indicates protection against water. A higher IP rating means that the device is more robust and suitable for various environments, making it an important consideration in the design and selection of electronic equipment, especially in surveillance and network video applications.

While electric resistance, temperature resistance, and environmental sustainability are important characteristics for various devices, they do not fall under the specific scope of what the IP rating measures.
