Some CCTV Cameras have IP66 some don't, What does IP66 mean?
Posted by Camille Chiu on
The IP rating system
- The IP Code (or International Protection Rating, sometimes also interpreted as Ingress Protection Rating*) consists of the letters IP followed by two digits and an optional letter. As defined in international standard IEC 60529, it classifies the degrees of protection provided against the intrusion of solid objects (including body parts like hands and fingers), dust, accidental contact, and water in electrical enclosures. The standard aims to provide users more detailed information than vague marketing terms such as waterproof.
- The rating’s first digit e.g. IP66 relates to the ingress protection against dust (6 means dust tight, see the table below)
- The second digit e.g IP66 relates to the ingress protection against water (6 means protected against heavy water jets, see the table below)
| Protection against solid objects | ||
| 1st Digit | Description | Definition |
| 0 | Non-protected | No special protection |
| 1 | Protected against solid objects greater than 50 mm | A large surface of the body such as the hand (no protection against deliberate access). Solid objects exceeding 50mm diameter |
| 2 | Protected against solid objects greater than 12 mm | Fingers or other objects not exceeding 80 mm in length. Solid objects exceeding 12 mm diameter |
| 3 | Protected against solid objects greater than 2.5 mm | Tools, wires, etc of diameter or thickness greater than 2.5 mm. Solid objects exceeding 2.5 mm diameter. |
| 4 | Protected against solid objects greater than 1.0 mm | Wires or strips of thickness greater than 1.0 mm. Solid objects exceeding 1.0 mm |
| 5 | Dust protected | Ingress of dust is not totally prevented but dust does not enter in sufficient quantity to interfere with satisfactory operation of the equipment |
| 6 | Dust-tight | No ingress of dust |
| Protection against liquids | ||
| 2nd Digit | Description | Definition |
| 0 | Non-protected | No special protection |
| 1 | Protected against dripping water | Dripping water (vertically falling drops) |
| 2 | Protected against dripping water when tilted up to 15º | Vertically dripping water shall have no harmful effect when the enclosure is tilted at any angle up to 15º from its normal position |
| 3 | Protected against spraying water | Water falling as spray at an angle up to 60º from the vertical shall have no harmful effect |
| 4 | Protected against splashing water | Water splashed against the enclosure from any direction shall have no harmful effect |
| 5 | Protected against water jets | Water projected from a nozzle against the enclosure from any direction shall have no harmful effect |
| 6 | Protected against heavy seas | Water from heavy seas or water projected in powerful jets shall not enter the enclosure in harmful quantities |
| 7 | Protected against the effects of immersion | Ingress of water in a harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time |
| 8 | Protected against submersion |
The equipment is suitable for continuous submersion in water under conditions, which shall be specified by the manufacturer |
