Fire detection

Reducing Fire Risk at Waste Management and Recycling Sites

Humans produce massive amounts of garbage each year. In the US alone, 700,000 tons of trash are produced per day.  All that garbage must go somewhere, and much of it ends up in waste management and recycling sites. These sites are at constant risk of fire. As the waste pile decomposes, chemical reactions that happen deep under the surface produce hot gases that are extremely volatile. In recycling facilities, highly combustible “fluff” materials can burn down a facility in minutes. Self-combustion is a constant threat in these facilities, and usually, by the time a fire is identified, the conditions are already such that the damage is widespread.

In addition to the financial damage these fires cause, there are serious environmental issues to consider. Due to the large amount of runoff from firefighter’s efforts to put out these fires, waste fires are a danger to the environment and public health. Stringent regulations of emissions from these facilities make early detection necessary, as unchecked fires could lead to large fines or even plant closures.

The most dangerous times are when the facilities are unmanned, as an unobserved fire could completely ruin an operation. In order to protect these facilities, several needs must be met. First, any detection system has to work equally as well at night as it does during the day. Next, the systems should be able to integrate seamlessly with the existing framework, and they should have IP capabilities, so that they can connect back to the main control center or be accessed remotely. They also need to have a very low occurrence of false alarms.

The best hotspot, smoke, flame, and fire detection solutions are thermal cameras with fire detection analytics. Thermal cameras that have all of these qualities are an effective technology for fire and loss prevention. They can detect a tiny rise in temperature, and when something in the region of interest passes a pre-set temperature threshold, an alarm is sent to the control center. Alerts can also be sent to anyone with remote access, and can be programmed to alert the local fire department as well, bringing the response time down significantly and saving millions in lost property damage. They can also lower insurance costs for facility owners and managers, as they significantly reduce the risk of massive fires, currently the biggest threat to these operations.


8 Thermal Imaging Innovations That are Making Our Lives Better

Thermal Imagers for Early Cancer Detection

Yes, you heard me right. Breast cancer, one of the most common cancers, affects millions each year worldwide, with late detection being one of the biggest problems. Breast thermography, now being practiced in a number of locations, is being used to scan for angiogenesis (new blood vessel formation), one of the very first measurable signs that something might be wrong. While not recommended as a replacement for traditional diagnostic methods, this new technology has important implications that warrant further study.


Thermal Binoculars for Tactical Missions

No matter your mission, eventually you are going to run out of daylight. This makes handheld thermal devices especially important lifesaving gear for coast guard, law enforcement, and SWAT teams. Police and search and rescue teams across the globe are now regularly using handheld thermal cameras to find missing people and fugitives, saving lives and getting criminals off the streets faster than ever before.


Thermal Gas Detection Cameras

While these are still priced for professional use, their very existence is improving your life by making it possible for companies and government regulatory bodies to instantly render fugitive emissions visible. This has major environmental implications, allowing for fast identification and response to gas leaks. Less harmful gas leaks mean cleaner air, and that’s good for everybody.


Thermal Monocular (Scope) for Wildlife Observation

For those of us that love the outdoors, observing wildlife in its natural habitat, whether at sea or on land, presents one of the biggest challenges (and is something we spend millions on vacations for each year). Animals are careful by nature, and hiding from humans comes with the territory. Often, you could be within several feet from a multitude of creatures and never know it. The thermal monocular solves this problem, by allowing you to reveal and enjoy animals in the wild, long before you get close enough to scare them away.


Thermal Cameras for Your Mobile Device

Handheld thermal cameras are one of the most popular consumer gadgets of the year, with good reason. Once only for the wealthy, you can now own a seriously powerful professional grade thermal imager for less than the cost of a new TV. Useful for everything from taking gorgeous pictures, to majorly reducing your energy bills, to scanning dark parking lots before walking to your car, the personal thermal camera is one little tool that is improving lives everywhere in a big way.


Nighttime Driving Assistance

Driving at night, or in bad weather can be pretty scary, especially in unlit rural areas. To combat this problem, some new vehicle models are being developed with integrated thermal night driving systems.  Much like the color rear-view cameras that have become standard in newer model cars, thermal night driving assistance cameras can “see” in the dark, rain, fog, and snow, and have a screen that shows you a clear thermal video feed of the road conditions around you, making night driving easier, and safer.


Thermal Cameras Make Cities Safer

Traffic cameras with thermal cores can improve traffic patterns by reading the environment and responding accordingly. If a biker or a pedestrian is approaching, the camera will respond by changing the light so that they can safely pass. The cameras also reduce waiting time and wasted gas for automobiles at stoplights by turning (and keeping) the light green if no one is coming from the other direction.


Wearable thermal imagers

Wearable cameras, like helmet mounted thermal imagers, might seem like futuristic gear, but they are already being utilized by teams of firefighters. These devices are important, lifesaving gear that every firefighter should have, as they see through smoke, and can identify people who are trapped or unconscious. Helmet thermal cameras are especially important, as firefighters need their hands free when they are navigating dangerous burning buildings.


From saving lives and the environment, to keeping you safe, these incredible innovations all use thermal imaging technology to improve our lives.

Thermal cameras for search and rescue saving lives at sea

Coast guard and search and rescue teams face extreme conditions daily, as a regular element of their jobs. At night, and especially in stormy weather, efforts to save people in the water can quickly become a nightmare scenario simply because they can’t be seen. Handheld thermal cameras can save rescue teams precious minutes that make the difference between life and death, by revealing the location of people that have been swept overboard and are in imminent danger of drowning. These cameras display images that are based on differences in heat, not on light, and this is what makes them invaluable to crews working against the clock to save lives.

Using Handheld Thermal Cameras for Marine Safety

Modern thermal binoculars can be used at sea as well as on land. They make it possible to detect a human target as far away from a vessel as 2000 meters, greatly increasing the survivability of people fighting for their lives in the water.

In fact, with thermal imaging technology, you have access to clear and sharp pictures regardless of time of day or weather conditions. The light weight of the thermal monocular device is also important since it makes it easier to handle and operate the camera, when seconds can make the difference between being lost at sea and being pulled from the water.

The thermal cameras are also excellent for detecting hazards like rocks, ice, floating debris, and other, smaller vessels. This makes it possible to avoid accidents that might lead to costly damages and losses.

Easy to use even for the beginner

Another great advantage of modern thermal imaging technology is that it is easy to operate, even for a person that has never worked with this type of equipment before. With intuitive layout and functions that are clear and easy to understand, people working for the coast guard or marines can be quickly trained on the equipment and start benefiting from the advantages of being able to see in the dark. Energy efficiency also comes in handy during rescue missions that take more time than initially expected.

Using handheld thermal cameras at sea can spell out the difference between life and death. T hey are especially helpful in dark, freezing, and stormy conditions where every second counts. This makes thermal technology invaluable for this application, and it should really be standard equipment for any vessel or rescue team going out to sea.

4 Reasons to Choose Uncooled Thermal Systems

  • They cost a lot less

While thermal security cameras with cooled systems undeniably perform better at extreme long ranges in clear weather (think over 20km), most surveillance needs are more localized. For human recognition surveillance of ranges up to 10km, systems using uncooled thermal sensors can be much cheaper than systems using cooled sensors, since uncooled thermal sensors don’t need to use a more expensive cryocooler.

For security and surveillance systems that need to monitor an immediate area, like the land and perimeters surrounding sensitive infrastructure, corporate properties, and private compounds, using systems with uncooled sensors can save you major cash.

  • They need a lot less power to operate

Uncooled thermal sensors use microbolometers to detect infrared radiation, which have relatively low energy consumption requirements compared to cryocoolers, the detectors in cooled thermal systems. Put simply, uncooled thermal sensors do not require cooling, which considerably lowers the amount of energy needed to power it.

  • They need a lot less maintenance over time

While cooled cameras are the system of choice for extreme long-range surveillance needs, they do require more attention (i.e. routine cryocooler rebuilds every 8,000-15,000 hours of operation). On the other hand, uncooled systems, while quite advanced, have far fewer delicate mechanical components and moving parts to break down. This advantage gives them much longer service lives, and an experience where users can basically set up the camera and walk away.

  • At closer ranges, they see better in bad weather

Specifically, in conditions of Category II fog (visibility < 610 meters), systems with uncooled thermal sensors will outperform systems with cooled sensors because of the IR detection range of each type of sensor. Uncooled thermal sensors image in the Long wave Infra-Red (LWIR) band, while cooled sensors operate in the Mid-wave Infra-Red band (MWIR). Basically, Category II fog reduces the imaging capabilities of sensors operating in the MWIR band to that of the naked eye, making uncooled thermal sensors the only way to see clearly in such conditions.

So, to recap… for security demands that require human recognition at closer ranges (up to 10km), uncooled thermal cameras compared to cooled thermal cameras cost less to buy, cost less to maintain, need significantly less power to run, and they have serious imaging advantages in cases of bad weather. Maybe it’s time you upgrade to a thermal security solution?
