Introduction
When it comes to cameras used in demanding environments such as drainage, HVAC, and engineering, protection from dust and water is paramount. This protection is quantified by Ingress Protection (IP) ratings. This article delves into what ingress protection means, the significance of IP ratings, and why these ratings are crucial for drain and handheld cameras. At UK inspection Camera we ensure that our cameras are cut out for the job they are set to do.
What is Ingress Protection?
Ingress Protection (IP) is a standard set by the International Electrotechnical Commission (IEC) to classify and rate the degree of protection provided by mechanical casings and electrical enclosures against dust, water, and accidental contact. This system is crucial for understanding how well a device is protected from environmental factors.
The Importance of Ingress Protection
In environments where cameras are exposed to harsh conditions, understanding their IP rating helps in determining their durability and reliability. For instance, drain cameras need to be highly resistant to water and debris, while handheld cameras used in HVAC systems should be protected from dust and moisture.
Understanding IP Ratings
An IP rating typically consists of two digits. The first digit indicates the level of protection against solid objects like dust, while the second digit signifies the protection against liquids.Below is a breakdown of the numbers for Solids and Liquids as a quick cross reference
Solid Particle Protection
| First Digit | Protection Level |
|---|---|
| 0 | No protection |
| 1 | Protection against objects larger than 50mm |
| 2 | Protection against objects larger than 12.5mm |
| 3 | Protection against objects larger than 2.5mm |
| 4 | Protection against objects larger than 1mm |
| 5 | Dust protected (limited ingress permitted) |
| 6 | Dust tight (no ingress of dust) |
Liquid Ingress Protection
| Second Digit | Protection Level |
|---|---|
| 0 | No protection |
| 1 | Protection against vertically falling water drops |
| 2 | Protection against water drops when tilted up to 15 degrees |
| 3 | Protection against spraying water |
| 4 | Protection against splashing water |
| 5 | Protection against water jets |
| 6 | Protection against powerful water jets |
| 7 | Protection against immersion up to 1 meter |
| 8 | Protection against immersion beyond 1 meter |
| 9 | Protection against high-pressure, high-temperature water jets |
Different Grades of Ingress Protection
Basic IP Ratings:
- IP00: No protection.
- IP20: Protection against large objects but not water.
- IP54: Protection against limited dust ingress and water spray.
Advanced IP Ratings:
- IP65: Protection against dust and low-pressure water jets.
- IP67: Protection against dust and temporary immersion in water.
- IP68: Protection against dust and prolonged immersion under pressure.
Why Ingress Protection is Important for Cameras
Drain Cameras
Drain cameras are used in sewers and pipelines, often submerged in water and exposed to various debris. High IP ratings (e.g., IP68) ensure that these cameras function effectively without being damaged by water or particles.
Handheld Cameras
Handheld cameras used in HVAC and engineering need to be durable against dust and occasional splashes. An IP65 rating is typically sufficient to ensure reliability and longevity in such environments.
Ingress protection in Various Industries
Drainage Industry
Usage: Inspecting sewer lines and pipelines.
Required IP Rating: IP67 or higher to handle submersion and debris.
HVAC Industry
Usage: Checking air ducts and ventilation systems.
Required IP Rating: IP54 to IP65 for protection against dust and water spray.
Engineering Industry
Usage: Inspecting machinery and structures.
Required IP Rating: Varies, but often IP54 to IP67 for protection against dust and water.
