Ingress Protection Rating (IP66 and IP67)

Most of the cameras that we carry in our catalog are weatherproof, and we identify the camera’s level of tolerance to the extreme conditions with it’s Ingress Protection Rating. This “IP Code” (not to be confused with the IP address) was made to define how well devices like our IP cameras hold up against the elements, namely dust and water. In this article, we’ll go over what all of the different levels of Ingress Protection are, when to use the different IP ratings, and what varying degrees of Ingress Protection our products offer.

What do the numbers in the Ingress Protection rating mean?

The IP code always consists of two numbers after the letters “IP.” The first digit can range from 0-6, and represent the enclosure’s effectiveness at keeping out solid particulate, like dust. “0” would define something that has “No protection against contact and ingress of objects,” while the number “6” means that the enclosure allows “no ingress of dust; complete protection against contact (dust tight).” Refer to the chart below to see the full breakdown of all 7 categories defined in the first digit of an IP code.

First Digit

Level sized Effective against Description
0 No protection against contact and ingress of objects
1 >50 mm 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 Fingers or similar objects
3 >2.5 mm Tools, thick wires, etc.
4 >1 mm 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 air flow.

 

The second digit in the IP code refers to it’s resistance to water. This digit can range from 0-9, where “0” means that the device is not water resistant at all, and “9” is “protected against close-range high pressure, high temperature spray downs.” The chart below has the specifics of all 10 levels of protection against harmful egress of water.

Second Digit

Level Protection against Effective against
0 None
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.
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.
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 shield in place) for 5 minutes minimum.
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. Test b) is conducted (without shield) for 5 minutes minimum.
5 Water jets Water projected by a nozzle (6.3 mm) against enclosure from any direction shall have no harmful effects.
6 Powerful water jets Water projected in powerful jets (12.5 mm nozzle) against the enclosure from any direction shall have no harmful effects.
6K Powerful water jets with increased pressure Water projected in powerful jets (6.3 mm nozzle) against the enclosure from any direction, under elevated pressure, shall have no harmful effects. Found in DIN 40050, and not IEC 60529.
7 Immersion, up to 1 m 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 m of submersion).
8 Immersion, 1 m or more depth The equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. However, with 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 is expected to be greater than the requirements for IPx7, and other environmental effects may be added, such as temperature cycling before immersion.
9 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 upright, no turntable required, and are tested freehand for at least 3 minutes at distance of 0.15–0.2 m.

 

Common Ratings And When To Use Them

All of our cameras are either IP66, IP67, or IP68 cameras. If proper weatherproofing practices are followed when the camera is installed, then the camera will stand up fine against rain, snow, and dust.

If the camera is going to be continuously drenched with water for 30 minutes or less from time to time, then you will need to go with at least an IP67 camera. An IP67 camera will perform well in situations where the camera might be splashed by waves or hit with water on a regular basis, like a carwash security system or other extremely wet environment.

While we don’t suggest it, if you have a camera that is going to be continuously submerged in water, then you would need to go with an IP68 camera. Our Exterior Vehicle IP Cameras are rated for this, in case they are installed on a boat or other marine vehicle.

Analog Security Cameras vs Digital IP Security Cameras

Overview

Security cameras come in two distinct types, Digital(IP) and Analog(AHD, TVL, TVI, HD-SDI, HD-CVI). Many types of these security cameras are still widely in use. However the security camera industry continues to push the limits of resolutions, and as a result, the use of digital IP security equipment continues to increase while analog continues to decline. Let’s take a look at the general differences in analog surveillance cameras and IP surveillance cameras.


RJ-59 Cable Ends

RJ-59 Cable Ends-Security Camera

Analog Security Cameras

1. Analog cameras send a video signal to an encoder(DVR) which then processes the signal and records it.
2. Analog cameras require a direct connection to the DVR.
3. Analog security cameras require two cables, one for power and one for video.
4. Analog cameras have a limited platform of resolutions available.

RJ-45 End

Cat5e and Cat6 can be used for IP cameras

IP Security Cameras

1. IP Cameras encode the video signal at the camera and send the video to Network Video Recorder(NVR) through an internet protocol(IP).
2. IP cameras require a connection to the same network as the NVR and don’t have to be directly connected to the recorder.
3. IP Security cameras use Power over Ethernet(PoE) which means you only have one cable going to the camera that supplies power and transfers video.
4.The worst IP camera resolutions are far superior to the best analog resolutions.


Analog Surveillance Camera Types:

Analog Camera Types: TVL, AHD, HD-CVI, HD-SDI, TVI

Television Lines(TVL) :

TVL is the oldest of all the analog camera resolution rating systems and was popularized by Chinese manufacturers in an effort to artificially inflate the resolution of their cameras, making them seem like they had higher resolutions. TVL cameras have incredibly low resolution, and are usually black and white. While most modern resolution ratings reference the vertical pixel count (1080p, 4k, etc.), TVL as a rating refers to the specification of an analog security camera’s horizontal resolution power. It is common to see TVL resolutions measuring 480 TVL,  600TVL, 650TVL, 700TVL.

Typical TVL Resolutions in Pixels:
480 TVL: 510 x 492 (0.2 Megapixel)
600 TVL: 768 x 494 (0.3 Megapixel)
650 TVL: 811 x 508 ( 0.4 Megapixel)
700 TVL: 976 x 582 ( 0.5 Megapixel)

Almost all of this equipment is phased out or in the process of being replaced. If you are installing new security cameras and using TVL cameras, you are installing old technology with hard to find replacement parts.

Expect TVL cameras never to have a resolution greater than 720P

AHD, HD-SDI, & HD-CVI:

Analog HD, HD-SDI and HD-CVI CCTV cameras are capable of capturing video surveillance footage at a 1080p resolution. These high definition analog surveillance cameras must be used with a special surveillance DVR that supports their video signals for encoding. All of this hardware still uses the BNC Coax cabling (RJ59) and was introduced as a way to achieve High Definition over coax.

The current price, availability, and interoperability of these security camera systems makes it a bad choice for a new install or a retrofit.

Expect High Definition analog cameras to have a max resolution of 1080P

Transport Video Interface(TVI):

TVI is currently the best and most affordable transitional technology available for upgrading your old analog system to High Definition without pulling new cable.  TVI solved what AHD, HD-SDI, & HD-CVI had problems with or failed to do. Able to acheive greater cable distances and better resolutions while still utilizeing the same coaxial TVI became a large contender in the analog cctv market. TVI supports HD video signal (1080P/720P), audio signal, and digital signal transmissions. If your looking to upgrade your old analog system and don’t have the option to pull new cable for an IP based Security System then TVI may be an option for you.Typical TVI Resolutions in Pixels:
720P: 1280 X 720 (1 Megapixel)
1080P : 1920 X 1080 (2 Megapixels)

Expect TVI analog cameras to have a minimum resolution of 720P and a maximum of 1080P.

IP Surveillance Cameras

IP security cameras have impressive resolutions and ever-evolving technologies. IP cams have introduced some of the biggest changes in the security world with their crystal clear 4k resolutions and smart video analytics. If your buying a security system for the first time or upgrading an existing one you should definitely consider using an IP security camera system. It has many benefits over analog and the overall install is easier compared to conventional security surveillance systems.Typical IP Resolutions in Pixels:
1920 x 1080 (2 Megapixels) 1080P HD
2688 x 1520 (4 Megapixels) HD+
3840 x 2160 (8 Megapixels) 4K+
And More!
vcdto4k
Expect IP security cameras have minimum resolution of 1080P.

Summary

While this article is short and touches on the basics of analog security cameras vs IP security cameras many more differences co-exist between both styles of cameras. One of the easiest ways to identify an analog camera is by the camera cable end. Analog cameras will require two cables, one for power and one for video while IP cameras use PoE and only require one cable to work.
