Video surveillance for fire detection

"Computer vision could minimize damage from forest fires in the Far Eastern Federal District"


The arrival of spring brought the Far East not only the long-awaited warmth and sun, but also a new wave of forest fires. At the moment, the FEFD is among the leaders in the number of spontaneous fires. As of April 18, the emergency situation was introduced in the Amur Region, and in the Primorsky Territory - a special fire-fighting regime. Softline experts - a company that is currently implementing a pilot project for the organization of a video fire detection system in Yakutia - described how modern technologies help regions suffering from forest fires.
Even if the forest fire is located far from populated areas, and the fire does not threaten their inhabitants, an unpleasant consequence becomes possible - the longer the forest burns, the harder it is to breathe people. Dmitry Bubnov, the public services sales manager for Softline, Dmitry Bubnov, believes that it is possible to significantly reduce the damage caused by fire with the help of modern technologies: "A significant part of Russia's square is occupied by forest, and it is not surprising that, beginning in late spring, almost all regions in that or to a different extent, they face forest fires and their consequences. Currently, Russian forestry uses several methods of detecting fires: data from satellites, air and ground patrols and using video surveillance cameras are installed on the towers of cellular communications. "

The satellites are least accurate in detecting ignition - they take pictures of the earth with a certain periodicity - only when they are over the area under investigation, which makes it impossible to detect fires promptly and quickly to take measures to localize and extinguish them. In addition, the satellite equipment captures not fires as such, but the thermocouples - areas with increased temperature, one can only see the point on the map if there is a fire in the forest and more reconnaissance is required. Aviation patrols are carried out once a day for in advance agreed, given route, or, if the level of fire hazard is increased, twice. From a height you can define a forest fire more accurately, but, again, not quickly enough: in certain weather conditions for several hours, the fire can spread to a significant area.

The same drawbacks have ground patrolling, when the forester rides around a designated area in a car, in inaccessible places using unmanned aerial vehicles to expand the control zone. Automated posts of video surveillance, carrying out around-the-clock monitoring of the surrounding areas, appeared in Russia for a long time (in 2010-2011).

Their undeniable advantage is that cameras are installed on the existing infrastructure of various high-rise buildings - buildings, towers, industrial facilities and others, therefore, monitoring is organized relatively modestly. Modern cameras have low weight and low power consumption. They use computer vision algorithms, they can detect small, beginning forest fires within a radius of 15-20, and large ones - for 30 kilometers. The cameras rotate 360 ​​degrees, fix smoke and immediately transmit the corresponding signal to the regional dispatching service of forestry.

This makes it possible to promptly send employees to the site of fire and eliminate fire before it begins to pose a danger to nearby settlements and their residents. Unfortunately, the forestry industry is conservative - new technologies penetrate here slowly.

At the moment, video surveillance on forest lands has not been established in all Russian regions, mainly in the regions and republics of the Central, North-West Federal Districts, the Volga region and the Urals. And in Siberia and the Far East - Irkutsk, Tomsk and Novosibirsk regions and in the Khabarovsk Territory began implementing projects to deploy video surveillance systems in 2017-2018.

Several pilot projects in Russian regions, not yet covered by video surveillance systems, are currently being implemented by Softline specialists. "One of the pilot projects company Softline is currently implementing in the Republic of Sakha (Yakutia). As part of the pilot, we installed a video surveillance system on the test site, in particular, in order to test how it will work under extremely low temperatures - in Yakutia in winter the temperature drops to minus 60 degrees.

Testing showed that the equipment is performing perfectly, which means that it does not need an annual dismantling for the winter period, "says Irina Prytkova, head of the department for work with government and academic organizations of Softline in the Far East Federal District." In general, the Far East is a very promising region for the introduction of computer vision and monitoring systems with the help of unmanned aerial vehicles. We are installing video cameras on cell towers, towers of television and radio broadcasting networks - even in remote areas such facilities are sufficient to organize an effective system for detecting forest fires. " According to the forecasts of Softline experts, the growth rate of interest in new technologies will grow in the near future: those regions that installed video cameras several years ago and regularly use them have already become convinced of their efficiency and plan further expansion and modernization of networks of automated video surveillance posts.

It is important to understand that the fire detected in time can be eliminated by several people without the involvement of expensive equipment, and the damage from such ignition will be minimal - which means that video surveillance systems are not only effective but also economically beneficial for regional authorities.
