IP Rating for Security Cameras

Lorex security cameras are given an environmental rating to indicate their suitability for installation in different indoor and outdoor environments. This rating is based on the camera's Ingress Protection (IP) rating. In most cases, Lorex security cameras are rated IP66, making them suitable for both indoor and outdoor installations.

What is an IP rating?

The IP rating tells you how resistant the equipment is to dust and liquids. It is a simple code that covers a range of international standards for enclosures and electrical equipment. This code was developed to provide customers with more information about how weatherproof an enclosure is, rather than just claiming that it is weatherproof.

What does the IP rating mean?

IP ratings are given as a two-digit code, such as IP54 and IP65. The first digit represents the level of protection against dust; the second digit represents the level of protection against fluids. The higher the number, the stronger the level of protection.

IP rating codes

The following chart explains each element of an IP rating and provides examples of all possible ratings:

Guide to Ingress Protection (IP) Ratings

DUST (1st Number)


Solid objects over 2" / 50mm (e.g. hand)


Solid objects over 0.5" / 12mm (e.g. fingers)


Solid objects over 2.5mm (tools and wires)


Solid objects over 1mm (small wires)


Dust - limited ingress (no harmful deposits)


Dust - completely protected (no ingress)


LIQUID (2nd Number)


Vertically - dripping water


Sprays of water when tilted up to 15


Sprays of water when tilted up to 60 vertically


Water sprayed from all directions - limited ingress permitted


Low pressure jets of water from all directions - limited ingress


Strong jets of water from all directions - limited ingress


Temporary immersion between 6" and 40" / 15cm and 1m


Long periods of immersion under pressure

What rating do I need?

Security cameras can be broken down into four classifications of environmental resistance:


IP Rating


Indoor <44 Indoor
Weather resistant 44 - 65 Indoor / Outdoor under shelter
Weatherproof 66 - 67 Indoor / Outdoor
Submersible 68 Underwater

NOTE: IP68 submersible cameras are specialized products intended for specific applications (e.g., mounting on a boat). Cameras rated for full submersion will be clearly labelled. Weather resistant and weatherproof cameras are not intended for submersion in water.

Extreme climate security cameras

Many Lorex security cameras have been engineered to withstand both extremely hot and cold climates. In fact, these cameras can continue to operate in temperatures as high as 140°F / 60°C and as low as -22°F / -30°C. That is not to say that these security cameras won't continue to operate after they hit one of these temperatures. They very well may continue to function in much higher and lower temperatures than those stated.

Outdoor installation tip

For outdoor installations, it is recommended that you position your cameras in a sheltered location even if they are weather resistant or weatherproof rated. Under shelter, the camera lens is protected from adverse weather conditions such as rain and snow, which can affect image clarity. Consider mounting the camera underneath an eaves or another structure that will protect the camera against the elements.

Homemade shelters

If installation under a structure is not possible, consider a homemade shelter. For example, mount your security camera to an outdoor wall inside of a plastic gardening pot. This will help keep the camera dry and the lens free of obstructions. Ensure that the shelter is not visible in the camera's recordings. Test the camera's night time performance to make sure that the shelter does not cause IR reflection, which can affect night vision quality. If you are making a shelter for a wireless camera, use a material such as plastic that does not greatly impact the wireless signal.

NOTE: Homemade shelters help to shield weather resistant and weatherproof cameras from adverse weather conditions that can negatively affect video quality. Building a homemade shelter is not an adequate weatherproofing method for indoor cameras.
