Which IP rating would indicate a camera is protected against the intrusion of dust and capable of withstanding heavy sprays of water?

The IP rating system is used to assess the degree of protection provided by enclosures against the intrusion of solid objects (like dust) and liquids. Each digit in the IP rating corresponds to a specific level of protection.

The first digit indicates the protection level against solid objects, with a higher number signifying better protection. A rating of 6 reflects complete dust-tight protection, meaning no dust can enter the enclosure at all.

The second digit indicates protection against liquids. A rating of 6 in this category means the device can withstand heavy sprays of water from any direction, providing significant protection against moisture ingress.

Given this understanding, an IP rating of IP66 confirms that the camera is both completely dust-tight and resilient against heavy water sprays, making it suitable for outdoor or harsh environments where both dust and water exposure are concerns.
