IP stands for Ingress Protection. It is an international standard that rates how well an electrical device is sealed against the entry of dust and water, expressed as two digits after the letters “IP”.

The higher each digit, the greater the protection. You will find an IP rating listed on the datasheet of every professional two-way radio and body-worn camera.

The number that matters is not always the highest one available. Choosing the right rating means matching the device to the environment it will actually work in.

This article explains what the most common IP ratings mean in practice and which one suits your site.

IP54: Offices, Retail, and Light Indoor Environments

IP54 is the standard entry point for professional radios and body-worn cameras used indoors.

The 5 means the device is dust protected: fine particles cannot enter in quantities that would affect its operation, though it is not fully sealed. The 4 means it can handle water splashed from any direction, covering spills, cleaning activities, and light rain at a doorway.

For most retail stores, corporate offices, hotels, and similar environments, IP54 is sufficient. Staff do not need a device built for a building site, but they do need one that can survive everyday handling, cleaning, and the occasional step outside.

IP55: Warehouses, Outdoor Events, and Sports Venues

The improvement from IP54 to IP55 upgrades water protection from splash resistance to low-pressure water jets from any direction.

This matters in environments where hosing down floors, cleaning machinery, or working outdoors in rain is routine.

For facilities teams covering mixed indoor and outdoor areas, event staff working across large outdoor sites, or warehouse operatives where cleaning routines are more intensive, IP55 is the more appropriate choice.

IP67: Construction, Manufacturing, and Outdoor Security

IP67 is the practical standard for demanding environments.

The 6 means the device is completely dust tight, and the 7 means it can withstand temporary immersion in up to 1 metre of water for 30 minutes. This covers heavy rain, mud, accidental drops into puddles or shallow water, and the kind of rough handling that construction and industrial sites produce.

For body-worn cameras specifically, IP67 is a sensible minimum for any outdoor security, patrol, or lone worker role. A camera worn throughout a shift needs to handle rain and cleaning between uses.

IP68: Marine, Utilities, and Heavy Industrial

IP68 covers prolonged immersion beyond 1 metre, with the specific depth and duration defined by the manufacturer.

It is the right choice for marine environments, water treatment sites, utilities teams working in exposed outdoor conditions, and any deployment where equipment may be submerged rather than just splashed.

IP69 is sometimes specified where high-pressure, high-temperature washdowns are part of the working routine, such as in food production or certain industrial cleaning applications.

Frequently Asked Questions

What does IP54 mean on a two-way radio?

The 5 means dust cannot enter in quantities that affect the radio’s operation. The 4 means it is protected against water splashed from any direction. It is suitable for most indoor professional environments and light outdoor use.

Is IP67 good enough for construction site use?

Yes, in most cases. IP67 handles complete dust protection, heavy rain, mud, and accidental immersion. For sites with regular high-pressure washdowns, IP68 may be more appropriate.

What IP rating should a body-worn camera have for outdoor security use?

IP67 is the recommended minimum for outdoor patrol and security roles. It will handle rain and routine cleaning between shifts.

Can a device rated IP54 or IP55 be submerged in water?

No. IP54 and IP55 cover splash resistance only. Only IP67 and above are rated for submersion. IP67 covers temporary immersion up to 1 metre for 30 minutes; IP68 covers deeper or prolonged immersion.

Does a higher IP rating mean a more durable device overall?

A higher IP rating means better protection against dust and water ingress, which contributes to longevity in demanding conditions. However, IP ratings do not cover drop resistance or build quality. Overall durability depends on the device as a whole, not the IP rating alone.

What is the difference between “waterproof” and “weatherproof”?

Neither term maps to a specific IP rating. Weatherproof typically implies splash resistance; waterproof usually means temporary shallow immersion at best. Always check the IP rating on the datasheet rather than relying on a general descriptor — if a product does not carry one, ask the supplier before purchasing.

What does IPX7 mean?

The X means solid particle protection has not been formally tested under the IEC standard. The 7 confirms the device has been tested for temporary water immersion up to 1 metre for 30 minutes. It does not mean the device has no dust protection, only that this has not been independently certified.

Does an IP rating cover saltwater exposure?

Standard IP ratings are based on fresh water testing. Saltwater is more corrosive and is not covered by the standard rating. Always check the manufacturer’s datasheet if saltwater exposure is a realistic risk in your environment.

What IP rating is standard for facilities management radios?

IP55 covers most facilities management roles, including outdoor patrols, plant rooms, and cleaning environments. Sites with more demanding conditions such as exposed rooftops, construction, or industrial plant may benefit from IP67.

Is an IP rating the same as MIL-STD-810?

No. IP ratings measure resistance to solid and liquid ingress only. MIL-STD-810 is a US military standard that covers a broader set of conditions including drop resistance, temperature extremes, and vibration. Many professional radios carry both certifications, but they test for different things.
