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.

 

Motion Detection In Security Cameras | When To Use It And Why Does It Suck (sometimes)?

One of the most popular features of security cameras is the ability to record only when something is happening in front of the camera. This has been the go to method for preserving that precious Hard Drive space, especially with resolutions always on the rise and with it recording storage demands. With event recording, you don’t have hours and hours of footage taking up space where nothing has happened. Up until now the most popular way of detecting an event is through motion.

How Does Motion Detection Work?

Motion detection is achieved by continuously monitoring each frame of video and averaging the background state of the scene, then if a significant portion of that scene (or percentage of pixels) changes from one frame of the video to the next, a motion event is triggered. For example, the camera is monitoring an empty hallway. Once a person enters the frame of the camera, the pixels that were of the floor and wall are now changed to the person. The camera logs a motion event and the recorder is told to begin recording. This technology was first introduced in analog security camera systems in the early-mid 2000s, but was fairly bad at giving accurate results. Unfortunately in the last decade, not much has changed.

Why Does Motion Detection Suck?

Motion detection events are still plagued with the same problems they had when they were first introduced. False positives from trees blowing in the wind, poor sensitivity, too much sensitivity, extreme shifts of lighting (i.e. a cloud moving in front of the sun), etc. have always caused this form of event detection to be less than useful. Some manufacturers have implemented the ability to exclude areas of the scene from triggering motion detection. For example, you can block out those trees that are always blowing in the wind, or the road traffic that is just visible at the edge of the parking lot. These features have helped, but never seem to work perfectly.
Another issue that needed to be solved was pre and post recording. In the early days, a motion event would occur and start recording, but you would inevitable miss the first couple seconds as the event was processed and the recorders Hard Drive spun up. Security Equipment Manufacturers solved this by building in a continuous buffer that always keeps the last few seconds or even minutes of video in memory. If a motion event occurs, the recorder knows to keep the buffered video and save it to the Hard Drive along with the footage from the point of the even on. But, even with these improvements, motion based recording still fails to be accurate enough to be useful in demanding surveillance and security applications.

So What Should I Use To Trigger Recording?

The advent of smart cameras and machine learning has opened up the market to a wide range of intelligent smart events that can be used to log and trigger many different aspects of your system. On the simple side of the spectrum, line crossing and region intrusion detection can be used in place of the relatively “dumb” motion detection. With line crossing, individual directions can be set to trigger and intrusion detection can require a certain amount of the region to be filled or that the object be present for a specified time threshold before an event is triggered. Some of the most advanced analytics include face detection, License Plate Reading and Logging, and People Counting. These advanced analytics can be used to more accurately monitor and interpret the actual events that are occurring in the surveyed area. Recording can now be triggered based on extremely specific criteria, such as if a specific license plate is detected, if there is a face seen, or if an object of significant enough size enters a specific region.

While motion detection has it’s place, it by no means is a complete or in many cases even a viable solution.

Do IP Cameras Require an Internet Connection?

We have found that a lot of people shopping for security cameras are under the impression that IP cameras require an internet connection to operate correctly, after all, it is right in the name. Though IP is an abbreviation for Internet Protocol, an IP camera system will work perfectly fine without an internet connection. You can view the cameras, record to a hard drive, and search through recorded footage using just a monitor and a mouse plugged directly into the NVR.

POE Surveillance System Layout Diagram All you need is an NVR, some IP cameras, a mouse, and a monitor to operate an IP system.

With our Carbon Series NVRs, there is a POE switch built-in, so all you need to do is plug our IP cameras directly into the back of it. The cameras will “Plug-and-Play,” so you don’t even need to access the cameras on the network during initial setup.

When you use an IP camera system without internet, you are setting up what is referred to as Closed-circuit Television, or CCTV. This is a system that involves one or more cameras that are only able to be seen on a handful private monitors. This is different from a Broadcast Television system, which is widely transmitted to a virtually unlimited number of users.

No Internet Means Limited Remote Viewing

Keep in mind that if you do not have your system plugged into a router that is connected to the internet, you cannot view your system remotely from your smartphone or PC. It would still be possible to view the system using a tablet, laptop, or mobile device using WiFi on-site if you set up a local network using a WiFi router.

Do Surveillance Cameras Actually Deter Criminals?

Most security professionals will say that installing surveillance cameras on the outside of your home or business is an effective method of deterring criminals from choosing you as a target. Is this just a marketing pitch to get you to buy cameras, or are there actual statistics to prove this?

The University of North Carolina at Charlotte conducted a study in 2012 that sheds light on the subject and gives us a better understanding of what is going on in a burglar’s mind when selecting a target. The University’s study, titled “Understanding Decisions to Burglarize from the Offender’s Perspective,” surveyed 422 incarcerated male and female burglars and asked them a number of questions about choosing a target, motivation for burglary, and the question that we will focus on in this article; the effectiveness of alarm and security camera systems.

What does 1000TVL mean? Avoiding Misleading Resolutions

Don’t Let Misleading Numbers Fool You

If you’ve been researching security cameras for a while, you have probably noticed that some cameras measure resolution using TVL (600TVL, 700TVL, 1000TVL) rather than 720p, 1080p, or Megapixels. This can be confusing and even misleading, which can make it very frustrating to figure out what you need for your home or business. In this article we’re going to break down what all of those numbers actually mean so that you can make an informed decision.

Should I use Cat6 or Cat5e for my IP Security Cameras?

Overview

A very common question regarding security cameras and installs is the type of cabling to use. Currently, 2 types of wiring are widely used for IP security cameras which are Cat6 or Cat5e twisted pair cabling.
Security Cameras Cat5e or Cat6

Cat5e

Cat5 Enhanced(cat5e) replaced the traditional Cat5 cable and introduced speeds up to ten times faster than Cat5 cable. This was considered the standard cable to use in the early 2000’s. It can handle up 1,000 Mbps of bandwidth.

Cat6

Cat6 is slowly replacing the standard cat5e cable and becoming a valid choice for many network related installs. It allows for ten times the amount of bandwidth, capable of 10,000 Mbps of bandwidth. It should be noted, though, that after 165 feet Cat6 is only capable of supporting 1,000 Mbps of bandwidth, the same as cat5e

What Cable for my security cameras?

Both cables are a reliable choice for security cameras. Currently, Cat5e cable is more than enough bandwidth for most IP security cameras on the market. This makes it a great choice for most surveillance installs. Almost all IP security cameras currently use less than a 100/mbps of bandwidth making cat5e a valid choice.

 

Resolution and Bandwidth Cat5e – Remaining Bandwidth Cat6 – Remaining Bandwidth @ less than 165 feet Cat6 – Remaining Bandwidth @ 165 feet
1080P @ 5/mbps 995/mbps 9,995/mbps 995/mbps
4MP @ 10/mbps 990/mbps 9,990/mbps 990/mbps
4K @ 30/mbps 970/mbps 9,970/mbps 970/mbps

 

 

If you are looking to future proof your install for future upgrades to your security cameras, you could use cat6, but if your cable runs are more than 165 feet, you might as well use cat5e because you will be subject to the same bandwidth. If you are looking to go even further into future proofing, you can look into cat6A which is capable of 10,000 Mbps past 165 feet.

 

5 Benefits of a Security Surveillance System

1. Deter potential theft

Security surveillance is an effective deterrent. Someone casing the neighborhood is more likely to choose the property with no cameras over the property with cameras. Having a surveillance system not only protects your property, but makes the community a safer environment for everyone.

2. Remote Access and live video feed

IP security surveillance systems have the ability to be accessible across multiple platforms. Smartphones, computers, and tablets can view and monitor the area with live video feeds. Depending on the security surveillance system, you may even be able to set up e-mail based motion alerts, so when a subject enters a certain area a notification will be sent to your smart device. Some systems even have the ability for you to open doors remotely and control other house peripherals.

3. Protect your Belongings

One of the more obvious benefits of a security system is that it helps protect your personal assets and valuables. Probably all of us can relate to a friend or someone who has been a victim to of a robbery. The use of a security surveillance system can help protect your precious valuables and the footage can be huge help in recovering or locating the parties involved.

4. Insurance

A security surveillance system could lower your monthly insurance premium. Saving you money and protecting the things that matter to you.

5. Peace of Mind

Knowing that your valuables are being protected definitely will give you peace of mind. You can check in on your kids, pets, or just make sure everything is ok.

Summary

Using a security surveillance system helps protect the things that matter most to you and has many other benefits as well. If you have been considering a security system take a moment to look around and understand what level of security that you need or want for your property. Also consider the possible benefits from the different types available in today’s market.

Three steps in selecting your IP home security system


It really is easy, but if you still need some help designing your system, we’re here to help… For FREE!

Overview

Securing your house with an IP security surveillance has many benefits and is actually an overall easy process. Most IP camera surveillance systems on the market are now plug and play, greatly simplifying the setup process. To get started in selecting your equipment follow these 3 easy steps on selecting the right IP security cameras and Network Video Recorder(NVR).

Step One:

Identify the area(s) to secure.

Depending on your needs and site layout this may vary greatly. For now, just note the number of cameras you think would be required. Common places to secure are the garage, backyard, mailbox, indoors, pool, front door, patio, back door, basement, storage shed, barn, kennel and many more.

Step Two:

Select the cameras based on the area you are trying to capture

One of the most important factors to consider when choosing a security camera will be it’s focal length. Focal length is a measurement of the distance between the lens and Image sensor. The focal length of a camera determines it’s field of view” or rather, “what the camera can see”. In security cameras we encounter fixed focal lengths and variable focal lengths. A Fixed focal length security camera is most commonly called a “fixed lens” camera, while the variable focal length camera is called a “varifocal lens” camera.

Fixed Lens Camera

  • 1.) Fixed Field of View (i.e. 75° FOV )
  • 2.) Fixed Focal length (i.e. 4mm Fixed lens)

Varifocal Lens Camera

  • 1.) Variable Field of View (i.e. 30°-100° FOV)
  • 2.) Variable Focal Length (i.e. 2.8mm-12mm varifocal lens)

Focal length is measured in mm and smaller focal lengths give larger FOV’s while larger focal lengths give a smaller FOV. In simple terms you can think of a fixed lens camera as a “what you see is what you get”, and a varifocal camera is going to give you the ability to adjust what the camera “can see”.

Step Three:

Choose an appropriately sized NVR for the application.

Choosing a NVR relies on a three key starting points which include: the amount of footage you want on storage, the amount of cameras you require to secure you area, and the incoming bitrate of the NVR. Let’s briefly touch on each item and how they interact with each other.

The amount of recorded footage that you want on file will dictate the Hard Drive size that you need to purchase. It is important to use a surveillance rated hard drive as they are designed for 24/7 read/write tasks. The amount of storage required is directly related to your total camera bitrate.

The amount of channels is usually pretty easy to determine since 1 channel = 1 camera. Generally speaking, grouping nvr’s by this specification is rather effective. However, pay attention to what’s actually going on, just because a nvr claims it is a 16 channel nvr doesn’t mean it will actually support all 16 cameras chosen.

Bitrate is probably the most important specifications of a nvr. It determines the overall resources available for accepting incoming streams from IP cameras. Bitrate is measured in mbps(megabits per second) and the bitrate varies for each camera depending on the resolution and FPS of that camera.

What does all this bitrate stuff mean? As a general rule we can say that a 1080p camera uses 5/mbps, while a 4k camera can use upwards of 20/mbps. So, if you had a 4 channel recorder with an incoming bitrate of 40/mbps this means you could use one 4k camera and three 1080P cameras(A total bitrate of 35/mbps). On that same nvr you could only use 2-4k IP cameras even though the recorder can support 4 channels/cameras. This is because all of the bitrate is allocated to the 2-4k cameras(40/mbps).

Next Steps:

Once you get your equipment, installation is as easy as running an ethernet cable to each camera and mounting the cameras in your desired locations. It’s that simple!

Summary:

Take the time to research the cameras you are buying and compare the different options available not one camera is perfect for every solution. Selecting a quality surveillance hard drive will ensure a stable storage method. Bitrate may seem overwhelming but it’s just a simple adding process, correctly paying attention to this factor can help you future proof your system. If you keep these simple steps in mind when selecting your IP surveillance equipment you can be positive that your system will record in the desired manner and have room to grow.
