Which infrared camera suits your requirements?

Thermal imaging cameras are used for non-contact temperature measurement and for the detection of twodimensional temperature distributions with high thermal resolution on stationary and moving measurement objects. The devices are durable, robust and suitable for industrial continuous operation. Our infrared cameras are used in process control and monitoring, quality control, early fire detection as well as for measurements in research and development.

Depending on the application our fixed thermal imaging cameras are available with different thermal and spatial resolutions, spectral ranges and temperature ranges as well as with different housing variants.

In addition the are numerous motor focus infrared lenses, including wide angle and tele photo lenses, for an optimal adjustment of the camera to different measurement objects and measurmeent object sizes at different measurement distances.

The World Looks Different Through an Infrared Camera

There are only two ways you can see something in the world. The first is to have an object that emits light. The light from this object then enters your eye and your brain interprets it. Examples of this type of object are lights and your computer monitor. For all of these types of objects, it doesn’t matter if the room is light or absolutely dark you will still be able to see the light emitting object.

The other (and more common) type of object does not emit light. Instead, to see these objects you need a nearby light source. The light from these sources reflects off the object and then the light enters your eye. Without the light source, there is no light to enter your eye and you can’t see it. Simple right?

Actually, it turns out that all objects are light emitters. It just happens that the light emitted from most objects is not visible to the human eye. Let’s take a look at an example. Here is an ordinary stove top eye. When you first turn it on, it looks just like it did when it was off even though it can get quite hot (don’t touch it!). After the eye gets very hot, it glows with a dark red color.

When objects get hotter, they do two things. First, they emit more light (higher intensity) and second the produce light with a shorter wavelength. Red is the longest wavelength in the visible spectrum (and blue-violet is the shortest visible wavelength). This implies that the much cooler stove eye should be emitting light with a wavelength longer than red light. We call this light infrared.

20181024Here is where the infrared camera comes in handy. The IR camera (sometimes called a thermal imaging camera) can detect this light that your eye can’t see. On top of that, it can look at this light and work backwards to calculate the corresponding temperature of the object. Here are the same stove top eye with an IR camera.

These are called “false color” thermal images. Since our human eyes can’t see IR light, how does the infrared camera display what it sees? It takes each temperature calculation and turns it into a different color. In this particular color palette, brighter and whiter colors represent higher temperatures with the dark blue the colder areas.

There is one important thing to understand. The infrared camera doesn’t always display the actual temperature of the object. Just like visible light, you could have an object that reflects IR light. How is the IR camera to know if this light was emitted from the object or reflected?

Commercial Security Corona Camera

Quality security corona cameras are important for anyone wanting to protect their assets whether it be personal or business.

There are many different types of security corona cameras for the home or business and we carry many of them. The most important thing is to find a system that is going to cover specific needs. Some handle just audio and video, others just video, there are some that are just burglar alarms, to alert to an intruder in the unwanted area. Security corona cameras have come a long way from what they were as now there is also Computer and Mobile monitoring as well.

Commercial Security corona cameras allow for safety of office equipment, supplies, staff and more. Keeping the office atmosphere safe and secure is very crucial to a business’s day to day actions in real time. Employees that feel safe and secure at work will show up to work more often, they will be less inclined to file false insurance claims, and an alarm system will help protect against loss from theft.

Keeping a property safe and secure is important in order to provide protection not only for our belongings, goods, surroundings, as well as the people we love and work with. One way this can be done safely is by installing Security corona cameras in the home or office.

Regardless of why our customer needs a security system it is vital that they receive one that will be tailored to their needs. Otherwise, thieves may be able to use blind spots to get in and remove valuable items from the property, and more.

History of Night Vision

Eagle30 night vision devices are most affordable, but rely on ambient light to function properly. They use an S20 photocathode that provides about 1000x light amplification.

Image resolution and light amplification are improved in the Eagle40 night vision devices. Utilizing a microchannel plate (MCP) and an improved image intensifier tube, coupled with an S25 photocathode, you get better brightness than first generation night vision.

Eagle70CC night vision is a step up from second generation in that the new photocathode is used. A microchannel plate (MCP) is still present and the new coating on the MCP increases tube life. An ion barrier film on the microchannel plate causes a halo effect when looking at bright light sources. Generation 3 night vision devices and rifle scopes consume more power, but have light amplification of 30K-50K.

Eagle70CC night vision devices differ from Eagle40 generation in the use of auto-gated technology and use of a thinner ion barrier on the microchannel plate (MCP). Automatic gating regulates the photocathode voltage, which makes the night vision device to automatically adjust to changes in light conditions. The thinned layer of the ion barrier improves image noise and luminous sensitivity. However, a thinner or removed ion barrier also decreases the life of the intensifier tube from 20,000 mean time to failure to 15,000 hours. Generally NV devices are replaced before reaching this point.

See into the night with our attractively priced nightvision devices, built by the best brands in the world. We offer Eagle30 Night Vision all the way through Eagle40 and even Eagle70CC Night Vision. Military, Law enforcement, security personnel, nature lovers, hunters and hikers will be amazed at the ability of these night vision devices to turn the darkest nights into light.

Thermal Imaging Cameras Help Firefighters See Through Smoke

As firefighters, our sight is one of our most precious commodities. But when fighting a fire, smoke can quickly rob us of that sense, essentially “blinding” us and handicapping our ability to perform effectively, find the seat of the fire and/or locate victims. Because of this, generations of firefighters have yearned to “see” through smoke—and now they can. In the past 15 years or so, thermal imaging cameras have been introduced into the fire service market, allowing firefighters to virtually “see” through smoke.

Thermal imaging cameras were originally used by the military, with law enforcement special operations units being among the first to adopt them for civilian applications. As thermal imaging cameras technology evolved, the fire service began to embrace it for use during interior structural firefighting. Today, thermal imaging cameras are available for firefighting use in both handheld and helmet-mounted units. (Goggles are also available, but for obvious reasons, they’re not typically usable for interior firefighting.) Commercial and industrial facilities have also found thermal imaging equipment to be very useful for checking on overheating of equipment and electrical wiring.

The Issue of Cost

It wasn’t that long ago that thermal imaging cameras were extremely expensive. The few departments that had them were at times being special-called long distances so other departments could use them. The cost of technology remains a major concern for administrators, because it can delay or prevent departments from placing new, ground-breaking equipment in field operations. Although thermal imaging cameras are still relatively costly today, prices have come down a bit, and thanks to a variety of grant programs, they are much more accessible to most fire companies.

How Thermal Imaging Cameras Work

Thermal imaging cameras can detect, or “see,” emitted heat energy through a variety of filters, including smoke and dust. They can also detect energy emitted through a door or wall, which indicates that they’re hot and that there’s most likely a lot of heat on the other side of the door or wall. Further, thermal imaging cameras can detect energy reflected off of water or mirrors, even though the heat may not actually be coming from those points. Important: Although they’re called “cameras,” fire service thermal imaging cameras only detect differences in heat signatures. Looking through a thermal imaging camera isn’t the same as viewing an object in normal light. Details of objects detected on camera may not be clearly visible, and there may be variations in depth perception, similar to the passenger side mirror on your car. It’s also important to remember that thermal imaging cameras don’t provide night-vision capabilities.

Thermal Imaging Camera Pros & Cons

There are several pros and cons to the different types of thermal imaging cameras. Hand-held thermal imaging cameras are portable and can easily be shared among several crewmembers. A firefighter who needs to exit the hazard zone can simply pass the unit to another firefighter who might be replacing him in that area. Any controls on the unit are at the firefighter’s fingertips; however, as the name implies, the hand-held unit requires a hand to hold it, which can slow firefighting operations.

The helmet-mounted camera allows firefighters to keep both hands free, which eliminates the issue of slow operations, but it’s strapped to the firefighter wearing it, so as soon as they leave the area, the (expensive) camera goes with them. Some helmet-mounted cameras can be removed from one helmet and attached to another, but it does take a bit of time to accomplish this.

There are also thermal imaging goggles, which can be used for search or other exterior operations, but they’re not currently made to interface with SCBA masks and generally aren’t designed for firefighting environments.

New production process promises cheaper infrared lenses

Driving a car in the country at night can be a scary. The combination of poor visibility and animals or other hard to spot obstacles on the road poses an obvious threat to both the car and its occupants. Some luxury models now have the option of forward looking infrared night vision systems, so you can see the animal in time to swerve. Unfortunately these systems are pricey, even as an aftermarket add-on, but that may soon change through the work of researchers. The researchers have invented a way of bringing down the cost of the infrared lenses down by 70 percent – opening the way to cheap cameras for the mass market.

Night vision devices are based on microbolometers, which are a kind of room-temperature heat detector. Arrays of these in the camera use infrared light to detect animals by their body heat. This body heat may be used to create thermal images on a screen or simply to activate an alarm. Microbolometers are very useful devices, but they cost a fortune because of the infrared lenses used in their construction. In order for microbolometers to see wider application, the cost has to be brought down.

Currently, lenses are made of crystalline materials like germanium, zinc selenide or zinc sulfide. These are very expensive and require costly grinding and polishing, so the IWM team went in search of a cheaper material that used cheaper processing. The key to this was replacing traditional material with amorphous chalcogenide glass. This is glass that contains cheaper elements like sulfur, selenium or tellurium and is commonly used in lasers and CDs and DVDs.

And it’s 70 percent cheaper.

The researchers are now working on adapting the process for mass production and are looking forward to the time when microbolometers are cheap enough to move out of the car market and into everyday life. They envision applications such as monitoring devices to assist the elderly, temperature monitoring in manufacturing and improving energy conservation by finding heat leaks in buildings.

Thermal Imaging Cameras Explained

Thermal imaging cameras are devices that translate thermal energy (heat) into visible light in order to analyze a particular object or scene. The image produced is known as a thermogram and is analyzed through a process called thermography. Thermal imaging cameras are sophisticated devices that process the captured image and display it on a screen. These images can be used for immediate diagnosis or processed through specialized software for further evaluation, accuracy and report output. Thermal imaging cameras take measuring temperature to the next level; instead of getting a number for the temperature you get a picture showing the temperature differences of a surface.

What Do Thermal Imaging Cameras See?

Visible light is what we see around us every day. It is the only part of the electromagnetic spectrum that we can see. Visible light only takes up a small area in the electromagnetic spectrum and infrared radiation (IR) represents a larger percentage. If we want to see what’s going on in other parts of the spectrum we need specialized equipment.

All objects absorb, reflect and sometimes transmit energy at different levels. Different materials will give off heat or cold energy at different rates. It’s this energy that can be detected by infrared equipment and displayed as images.

Thermal Imaging Camera Applications and Uses

Originally developed for military use during the Korean War, thermal imaging cameras have migrated into other fields and have found many uses. Firefighters use them to see through smoke, find people and localize hotspots of fires. Law enforcement uses the technology to manage surveillance activities, locate and apprehend suspects, investigate crime scenes and conduct search and rescue operations. Power line maintenance technicians locate overheating joints and parts to eliminate potential failures. Where thermal insulation becomes faulty, building construction technicians can see heat leaks to improve the efficiencies of cooling or heating. Physiological activities, such as fever, in human beings and other warm-blooded animals can also be monitored with thermographic imaging. They are also common tools used by home inspectors.

Thermal Imaging Camera Features

Thermal imaging cameras can be purchased with the bare minimum of features that only read the temperature of the fixed center crosshairs on the display or with multiple features that allow the user to select multiple moveable crosshairs and draw comparisons between them to show the high, low and average temperatures on the display. Thermal imaging cameras have user-selectable multiple color palettes, such as black/white, iron or rainbow. The iron palette is most commonly used by home inspectors. The black/white palette helps identify details on an image, and the rainbow palette has the best thermal sensitivity for displaying the differences in temperature. See sample images below of some color palettes.

How Do Monitor Camera over Internet Work

Instead of transmitting video over a video cable to a monitor or DVR, an monitor camera over internet transmits digital video over a data connection: ethernet, USB, WiFi, etc. Everything required to transfer images over the network is built into the unit. It is connected directly to the network, just like any other network device, like a printer or scanner. Depending on what type of monitor camera it is, it may save video to an attached memory source, connect to another device on the network for storage, or stream captured video to the internet.

An monitor camera over internet captures images the same way any digital camera does. What makes it different is its ability to compress the files and transmit them over a network. If a building is equipped with a network, the necessary infrastructure is already in place to install network cameras. If adding one or a few monitor cameras, a user may use a decentralized network camera, one that has its own control interface and storage medium built in. When installing multiple network cameras it can be wise to use a centralized network camera, which requires a network video recorder (NVR).

An NVR is a program that can store video from network cameras and allow for viewing of multiple monitor cameras at once. It is similar to a DVR, but while a traditional DVR is responsible for encoding and processing video from component monitor cameras, an NVR depends on the monitor cameras to encode their video, simply storing it and allowing for centralized remote viewing. NVR software can be installed on a dedicated device with its own operating system or on an existing computer. There are hybrid systems available that can accept both IP and analog inputs. These will often allow analog cameras to be viewed remotely along with any network cameras.

Security Cameras for Watching Your Car

We had heard many car owners who were frustrated about their cars being broken in, keyed, vandalized (egged or scratched), or having car tires slashed or destroyed while parking on garage, driveway, street curbside, parking lot or carport areas.

How can car owners make sure their cars are not vandalized or broken in when parking overnight in front of the house, carports, street, road, garage, apartment parking lot, underground parking garage?

Many car owners turn to car surveillance cameras, in-car security cameras, and car alarm systems to help keep an eye on their parked cars, especially overnight parking.

What Kinds of Car Security Cameras Work for You

Assumingly, many readers of this post are new to auto security cameras or searching for a good video monitoring camera or system.

Finding out car surveillance cameras or system that can meet your demand or fit your budget is not always easy. Make sure you have taken these factors into account.

Power Supply

There is not always a power outlet available near the parking lot or underground parking garage. True. Or running wires is next to impossible to the spot where your car is parked overnight.

Well? There are a few alternatives.

You could consider a parked car security camera like motion sensor battery-powered car security camera, or solar-powered outdoor camera. Or consider in-car security cameras like car spy/hidden camera, nanny cam, parked car dash cam, indoor home camera.

UAV thermal imaging camera for gas detection

Under certain circumstances, infra-red cameras are highly suitable for detecting gas escapes and the presence of gas in the air. They can be also helpful during tests on improving environmental safety. A thermal camera can detect greenhouse gases in the air, as well as gas leaks, which are hazardous to the environment and can threaten human health.

Some gases used in industry can significantly damage the environment and, therefore, it is essential to eliminate any uncontrolled leaks. Moreover, these leaks cost a lot.

“Traditional” methods for detecting gases require close contact of a probe with gas with the use of sensor technology. These methods are restricted due the time required and the risk of non-detection of some types of gases or too high selectivity (gas leaks to other places than where the sensor is located).

To detect gases, we offer a specially constructed infra-red camera, which is able to visualise gas on the principle of infra-red thermography. The thermal camera provides a full image of the scanned area and gas leaks are reflected in the image as changes in the intensity of detected radiation.

The thermal imaging camera is the ideal solution for the unmanned air vehicles (UAV thermal imaging systems) localization and detection of leaks of hazardous gases the option of standard communication with the environment through a CAN bus or PWM inputs. Of course, the thermal camera can record measured data, including GPS coordinates and the on-line HDMI transfer of the image to the side of the pilot.

The thermal imaging camera is a highly precise thermal camera with a sensitive, cooled quantum detector with the resolution 320×240 and with a competitive temperature sensitivity of 15 mK, which also enables to detect gases of very small concentrations.
