FireVu are pleased to announce the release of the latest upgrade to the FireVu flame detection algorithm available now with the FireVu 500, our premier video fire detector. The FireVu 500 uses intelligent flame and smoke algorithms to analyse the camera image in order to quickly and reliably detect fire.

This latest update has increased both the robustness of the algorithm and the detection range. The detector will react to the presence of even a small fire in the specified field of view in under 30 seconds. These times apply to the most challenging of environments and in the majority of cases detection is even faster.

The FireVu 500 has three pre-defined detection footprints, the largest of which has a range of up to 100m for flame-only detection. There are other offerings with ranges of 50m and 25m which have a wider field of view.

Complete solution

FireVu is a complete solution which can be used in a wide array of challenging environments for a variety of applications, unlike some other detection methods.

  • Aspirating smoke detectors and beam detectors can only be used indoors and struggle with large voluminous areas as they rely on smoke reaching the beam or pipes. Historically they have issues with dusty, dirty environments triggering false alarms or going into a trouble/fault state as filters become blocked, resulting in frequent extra maintenance.
  • Thermal imaging cameras are often prohibitively expensive and unless accompanied by an additional CCTV image provide little or no situational awareness, preventing the end user or system operator from being able to identify the true nature of the risk and adopt the most appropriate course of action.
  • Triple IR detectors have a limited range, the greatest of which is listed at 65m.

Full visual verification

  • A complete lack of any visual output means that any alarm received cannot be verified, with end users or fire authorities unable to assess the situation prior to attendance. Field experience has shown that this technology is susceptible to false triggers as a result of direct sunlight, either if used externally or from nearby entrances when deployed internally.
  • FireVu solves this situational awareness issue through full visual verification, courtesy of the real-time video stream.
  • Draws attention to exactly what triggered the alarm and where in the field of view it is through the use of colored boxes.
  • Let’s you immediately know the size and scale of the fire so appropriate action can be taken. From allowing someone to tackle it with a fire extinguisher to immediately evacuating the building.
  • Provides footage of the incident which will allow for post-event analysis to help determine the cause of the fire. This means processes can be improved and the site made safer in order to ensure there’s no repeat incident.

Tried and Tested         

FireVu conducts extensive fire testing both in-house and at independent facilities such as the BRE in Watford. The below tests were conducted using the Mid-range FireVu 500, which has a stated detection distance of 35m for both smoke and flame or 50m for flame alone. TF5 fires were performed at 20, 30 and 95 meters from the detector.

The videos viewable here are just a sample of the tests which have been conducted with the FireVu 500. They were all recorded by the camera itself and so represent the real footage that would be seen by an operator or end user.

Visually the FireVu 500 viewing software provides two levels of flame detection, the first being a Cyan box which is rendered around pixels that the FireVu 500′s intelligent algorithm has selected as a potential flame presence. A full alarm state is triggered when all the required criteria to be certain a flame is present are met and results in the second level of detection and a magenta colored box.

No Easy Solutions: Complex Causes Surround Growth Of Wildfires
No Easy Solutions: Complex Causes Surround Growth Of Wildfires

Understanding the underlying causes of wildfires enables us to control them better over the long haul. One element is climate change, which has created conditions prone to wildfires by increasing heat, changing rain and snow patterns, and shifting plant communities. But there are also other contributing factors in the growing scale and intensity of wildfires. One is the condition of the forests in Australia, California, and other areas where the incidence of wildfires has increased. In California, for example, it is well known that the forests are unhealthy and in need of more prescribed burns and other thinning efforts. However, given California’s 33 million acres of forest land, more than half of it publicly owned, even an ambitious effort like addressing the needs of a million acres a year would require decades to fix the problem. managing the landscape We as a society need to decide how we can restore our forests, and start a conversation about what that looks like" “We know that getting our forests back to a healthy state will be the most effective way to cope with fires in the future,” says Jessica Block, Associate Director for Operational Programs at the WIFIRE Lab at the University of California San Diego. “However, massive fires are destroying the ability of forests to recover." The goal is not to stop wildfires but to understand the role of fire as part of the natural processes of managing the landscape. “We as a society need to decide how we can restore our forests, and start a conversation about what that looks like,” adds Block. “We should think of forests as a system we live in, and a system that we should be able to live in. Understanding the system is the goal, so that we can make all the right decisions in the future.” identify and control wildfires Fires are eating up forests that are way too dense and that have way too many standing trees, and state and federal agencies alone cannot solve the problem. Furthermore, the stakes are literally life and death: Thousands will die, whether in the wildfires or from the effects of inhaling smoke. The negative impact on long-term health is impossible to measure. Especially troubling is the impact of wildfires at the so-called wildland-urban interface (WUI), where growing population centers border on wildlands at risk of fire. Current fire models are not designed for these areas, so more work is needed to address these specific risks. Almost everyone agrees that the solution is to identify and control wildfires at early stages before they get out of control and turn into huge fires that impact millions of acres. automatic detection capabilities Today, postings on social media are an early warning sign but may not identify the exact location of a fire New technologies are helping to identify nascent wildfires. One option is the addition of automatic detection capabilities to the AlertWildfire network of cameras that currently keeps watch throughout five Western states to provide early warning of wildfires. So far, human volunteers have been used to track the cameras, but automation is on the horizon. One application of machine learning is to detect a smoke flume. A critical element is the ability to tell the difference between smoke and clouds, which humans can easily differentiate but is difficult to automate. With machine learning, computers should be able to “learn” the difference. Soon, mechanisms will exist to detect the location of a fire via multiple inputs - web cameras, social media and satellite images. Today, postings on social media are an early warning sign but may not identify the exact location of a fire. Working together, the other tools can help to pinpoint the location. Alerts to fire dispatchers must be verified as real to avoid misuse of resources.

Australia’s Moonshot: To Be Global Leader In Wildfire Prevention, Resilience
Australia’s Moonshot: To Be Global Leader In Wildfire Prevention, Resilience

Andrew and Nicola Forrest have committed 50 million Australian dollars (US$35 million) to the Fire and Flood Resilience initiative through Minderoo Foundation, with a goal of raising an additional 450 million (US$320 million) in direct or in-kind support over the life of the program. The goal of the ambitious investment is to make Australia the global leader in fire and flood resistance by the year 2025. It is an audacious vision that requires an innovative approach, and the organization takes inspiration from the U.S. Apollo mission of the 1960s. In effect, it will be a “moonshot” to advance the cause of preventing and controlling wildfires. Specifically, the first mission, Fire Shield, seeks to ensure no dangerous bushfire in Australia will burn longer than an hour by 2025. respond to wildfires The Flood and Resilience Blueprint further seeks to provide every community in Australia the skills and resources to cope with fire and flood disasters. Finally, it seeks to provide “healthy landscapes” by improving ecosystems to be “immune” to fire and flood disasters. Founded in 2001, Minderoo Foundation exists to arrest unfairness and create opportunities to better the world  “We are not daunted by or afraid of taking on the toughest challenges,” says Karen O’Connor, Missions Lead for Minderoo Foundation’s Fire & Flood Resilience initiative. "Fire has a devastating and unfair impact on communities all around the world - and if we can help drive better approaches to prevent and respond to wildfires, we can have a profound influence.” Founded in 2001, Minderoo Foundation exists to arrest unfairness and create opportunities to better the world. black summer bushfires Minderoo Foundation stepped up after Australia’s black summer bushfires in 2019-2020 to help communities respond to and recover from the devastation. The organization also seeks to do whatever it can to mitigate the risk of large-scale damage due to bushfires and build resilience to future disasters. “We understand that fire and flood are critical ecological processes that enable many of Australia’s ecosystems to function, supporting regeneration and new growth,” says O’Connor. “Therefore, Fire Shield does not aim to prevent wildfires entirely but rather to prevent wildfires from becoming disasters.” ground truth data Fire Shield will progress using the “Mission” methodology that involves breaking down major problems into smaller elements that can be addressed in turn. Missions are outcome-focused and time bound. They rely on accurate baseline and ground truth data and an ability to measure impact to know when the mission has succeeded in its goal. Fundamental to the Mission approach is bringing the best people and expertise to the challenges at hand Fundamental to the Mission approach is bringing the best people and expertise to the challenges at hand - whether they are working in scientific research, in government, corporations or philanthropy. Having accurate data and measures are also essential. To that end, Fire Shield is working with partners to develop an ecosystem for data standardization and sharing in order to collectively leverage insights to address future hazards. emergency services “It is also about making sure that people working in fire and emergency services are provided with the right information, in a timely manner, to make the best decisions when responding to fire,” says O’Connor. An example is Fire Shield’s partnership with the Australasian Fire and Emergency Service Authorities Council to support all Australian emergency services to develop new capabilities for fire detection, information sharing, fire simulation and response as well as utilizing data for improved decision-making wherever they are. fundamental principles “No matter what we do, Minderoo Foundation is always guided by the evidence,” says O’Connor. Minderoo Foundation’s Fire & Flood Resilience Blueprint has brought the best available evidence and expertise together to lay out a resilience blueprint for Australia and to inform the design and selection of missions, including Fire Shield. It challenges us to go right back to scientific principles and look for the best possible solutions” Importantly, the Blueprint is a “living document” that can evolve as the evidence base grows. First order problem solving is about going to the fundamental principles that apply to a problem, rather than thinking through analogies or accepted wisdom. “It challenges us to go right back to scientific principles and look for the best possible solutions,” says O’Connor.  important resilience problems The initiative is committed to working collaboratively. To date they have secured more than 50 partners across corporations, governments and civil society - and they are always open to more. They are also actively looking to collaborate with international programs with similar goals, to ensure they can multiply rather than duplicate efforts.  “We intend to share and publish our work widely, and of course continue to build collaboration, which is central to our approach,” says O’Connor. “We see ourselves as an enabler encouraging, facilitating and convening dialogue among different organizations and sectors of society to identify the most important resilience problems - and get to solutions faster.”

The Origin Of One California Wildfire Was A Gender Reveal Party
The Origin Of One California Wildfire Was A Gender Reveal Party

An explosion of blue-colored smoke on Sept. 5, 2020 in Yucalpa, California, was the beginning of a large wildfire in El Dorado Ranch Park. The pyrotechnic device was essentially a smoke bomb designed to send plumes of pink or blue smoke rising into the air, designating the gender of an expected baby. The expectant dad had packed the target with a highly explosive substance called Tannerite and shot it with a high-powered rifle. The target was designed to explode in pink or blue to reveal whether the couple was expecting a boy or a girl. Flammable foliage When the device ignited, so did the dry, wild grasses growing up to 4 feet tall in the meadow at the park, 80 miles east of Los Angeles. In the peak of summer, Southern California foliage is extremely flammable, and there were already fires burning across the state. After being active for 11 days, the fire had affected 18,506 acres and was 63% contained. The family that sparked the fire sought to put down the flames using water bottles. Then they called 911. The responsible individuals were still at the park when firemen arrived, and there are also surveillance cameras. Wildfire Spread And Evacuation The fire spread from the park to the north on to Yucalpa Ridge that separates Mountain Home Village and Forest Falls from the City of Yucalpa. The fire threatened a nearby residential neighborhood, and some 21,000 people were evacuated. After being active for 11 days, the fire had affected 18,506 acres and was 63% contained. The pyrotechnic show was a variation on the popular trend of gender reveal parties, which seek to announce the gender of an expected infant in increasingly (and competitively) colorful and/or dramatic ways. The parties are often featured prominently on social media. Rising temperatures Also contributing to the fire was recent weather in California, whose terrain was scorching in record-breaking temperatures as high as 120 degrees F in early September. The California Department of Forestry and Fire Protection (CAL Fire) reminds the public that, with the dry conditions and critical fire weather, it does not take much to start a wildfire, and those responsible for starting fires due to negligence or illegal activity can be held financially and criminally responsible. Natural conditions and human activity Natural conditions are central to causing wildfires, although human activity can provide the triggers Natural conditions are central to causing wildfires, although human activity can provide the triggers, including downed power lines, sparks from tire blowouts, and barbecues that get out of control. The pivotal gender-reveal part is just the latest example. If not for the increasingly dry and scorched conditions that make wildfire so easy to ignite, such human events would be much less consequential. With thousands of acres of wildfire raging across California, the cause of one wildfire seems less important in the overall scheme of things. However, the event does emphasize how seemingly minor events can have a very large impact. Lightning and fireworks Another cause of recent wildfires was lightning with more than 10,000 lightning strikes sparking 376 fires on Aug 16 and 17, 2020. In a season of wildfires, use of fireworks, for whatever reason, is a particular risk. Fireworks cause an average of 18,500 fires each year in the United States. Of those, about 1,200 injuries are from less powerful devices such as small firecrackers and sparklers.
