What is the IP rating of the ZED2i and what does it mean?

The ZED2i depth camera is the first ZED camera with IP66 rating.

The camera is resistant to dust and water, subject to certain limitations.

What is IP rating?

Ingress Protection (IP) ratings measure how resistant a device is against solids and water. IP ratings are determined by the international standard EN 60529 (British BS EN 60529:1992 – Degrees of protection provided by enclosures (IP Code) and European IEC 60509: 1989 – Degrees of protection provided by enclosures (IP Code).

What is Solid Ingress protection?

The first digit of the IP rating indicates the level of the enclosure’s protection against the ingress from blocking solid foreign bodies such as dust, tools, or fingers that could be hazardous if were to come into contact with electrical components, parts, or circuitry within the enclosure.

Level sized Effective against Description
X --- X means there is no data available to specify a protection rating with regard to this criterion
0 --- No protection against contact and ingress of objects
1 > 50 mm/2.0 in Any large surface of the body, such as the back of a hand, but no protection against deliberate contact with a body part
2 > 12.5 mm/0.49 in Fingers or similar objects
3 > 2.5 mm/0.098 in Tools, thick wires, etc
4 > 1 mm/0.039 in Most wires, slender screws, large ants, etc
5 Dust protected Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment
6 Dust-tight No ingress of dust; complete protection against contact (dust-tight). A vacuum must be applied. Test duration of up to 8 hours based on airflow

What is Liquid Ingress protection?

The second digit of the IP rating indicates the level of the enclosure’s protection from blocking internal components against various forms of moisture (sprays, drips, submersion, etc).

Level Protection against Effective against Details

X

--- --- X means there is no data available to specify a protection rating with regard to these criteria
0 None --- No protection against ingress of water
1 Dripping water Dripping water (vertically falling drops) shall have no harmful effect on the specimen when mounted in an upright position onto a turntable and rotated at 1 RPM Test duration: 10 minutes. Water equivalent to 1 mm (0.039 in) rainfall per minute
2 Dripping water when tilted at 15° Vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle of 15° from its normal position. A total of four positions are tested within two axes Test duration: 2.5 minutes for every direction of tilt (10 minutes total)
Water equivalent to 3 mm (0.12 in) rainfall per minute
3 Spraying water Water falling as a spray at any angle up to 60° from the vertical shall have no harmful effect, utilizing either: a) an oscillating fixture or b) A spray nozzle with a counterbalanced shield. Test a) is conducted for 5 minutes, then repeated with the specimen rotated horizontally by 90° for the second 5-minute test. Test b) is conducted (with a shield in place) for 5 minutes minimum For a spray nozzle: Test duration: 1 minute per square meter for at least 5 minutes Water volume: 10 liters per minute (0.037 impgal/s) Pressure: 50–150 kPa (7.3–21.8 psi)For an oscillating tube: Test duration: 10 minutes Water volume: 0.07 liters per minute (0.00026 impgal/s) per hole
4 Splashing of water Water splashing against the enclosure from any direction shall have no harmful effect, utilizing either: a) an oscillating fixture or b) A spray nozzle with no shield. Test a) is conducted for 10 minutes. b) is conducted (without shield) for 5 minutes minimum Oscillating tube: Test duration: 10 minutes, or spray nozzle (same as IPX3 spray nozzle with the shield removed)
5 Water jets Water projected by a nozzle (6.3 mm (0.25 in) against the enclosure from any direction shall have no harmful effects Test duration: 1 minute per square meter for at least 3 minutes. Water volume: 12.5 liters per minute Pressure: 30 kPa (4.4 psi) at a distance of 3 meters (9.8 ft)
6 Powerful water jets Water projected in powerful jets (12.5 mm (0.49 in)) against the enclosure from any direction shall have no harmful effects Test duration: 1 minute per square meter for at least 3 minutes. Water volume: 100 liters per minute (0.37 impgal/s) Pressure: 100 kPa (15 psi) at a distance of 3 meters (9.8 ft)
6K Powerful water jets with increased pressure Water projected in powerful jets (6.3 mm (0.25 in) nozzle) against the enclosure from any direction, under elevated pressure, shall have no harmful effects. Found in DIN 40050, and not IEC 60529 Test duration: at least 3 minutes
Water volume: 75 liters per minute (0.27 impgal/s) Pressure: 1,000 kPa (150 psi) at a distance of 3 meters (9.8 ft)

Immersion, up to 1 meter (3 ft 3 in) depth Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 meter (3 ft 3 in) of submersion) Test duration: 30 minutes. Tested with the lowest point of the enclosure 1,000 mm (39 in) below the surface of the water, or the highest point 150 mm (5.9 in) below the surface, whichever is deeper
8 Immersion, 1 meter (3 ft 3 in) or more depth The equipment is suitable for continuous immersion in water under conditions that shall be specified by the manufacturer. However, in certain types of equipment, it can mean that water can enter but only in such a manner that it produces no harmful effects. The test depth and duration are expected to be greater than the requirements for IPx7, and other environmental effects may be added, such as temperature cycling before immersion Test duration: Agreement with manufacturer depth specified by the manufacturer, generally up to 3 meters (9.8 ft)
9K Powerful high-temperature water jets Protected against close-range high-pressure, high-temperature spray downs. Smaller specimens rotate slowly on a turntable, from 4 specific angles. Larger specimens are mounted in the intended position when being used, no turntable required, and are tested freehand for at least 3 minutes at a distance of 0.15–0.2 meters (5.9 in–7.9 in). The specific requirements for the test nozzle are shown in figures 7, 8, & 9 of IEC (or EN) 60529. This test is identified as IPx9 in IEC 60529 Test duration: Fixture: 30 sec. in each of 4 angles (2 min. total), Freehand: 1 min/m2, 3 min. minimum water volume: 14–16 liters per minute (0.051–0.059 impgal/s) Pressure: 8–10 MPa (80–100 bar) at a distance of 0.10–0.15 meters (3.9 in–5.9 in) Water temperature: 80 °C (176 °F)

How can I further protect my camera?

The ZED2i is IP66-rated. It has been tested to operate outdoors with protection against thunderstorms and heavy rains for up to 30min.

If you plan to use your camera outdoors 24/7, we suggest you provide a top cover limiting the amount of direct water hitting the case for a prolonged amount of time.

Note: the camera is not protected against water immersion. For underwater operations, an IP67 or IP68 external case is required.
