It's common to see IP67 protection as a feature in premium outdoor camera's specifications. It's especially important to have this IP rating as the proof of quality when purchasing an outdoor security device in Canada.
The first two letters "IP" stands for "Ingress Protection" and is the International Protection Marking per IEC standard 60529. The most common use of an IP rating is how protected a product - such as a camera - is from a solid or liquid entering the product.
Following the letters "IP" are typically 2 digits which indicate the level of protection of the product. The first digit indicates the level of protection a product has from a solid - i.e. dust or a tool. The second digit indicates the level of protection a product has from liquid intrusion in certain volumes, pressures, or temperature.
For example, an IP camera that is IP67 rated will remain protected and fully operational in most industrial applications, including those where the camera is exposed to water spray, rain, debris, etc. The "6" indicates the sensor is dust tight. while the "7" indicates the sensor can be completely submerged in 1 meter of water for up to 30 minutes before the moisture penetrates the housing.
Please refer to the chart below as a quick reference for understanding IP ratings.
