Arrow neural network: Fire extinguishing equipment no longer needs to be checked

Reading time2 min
Reach and readers3.5K

Every day, every single day, devices in fire suppression systems need to be checked! When these are enormous warehouses spread across vast territories, a security guard has to constantly walk around and inspect all of them — just for this one task. The pressure gauge has become a symbol of punishment in fire safety authorities.

Millions of analog sensors are also used in gas and water distribution systems, as well as in many other industries.

SpesLab-Gambit: a convenient neural network object annotation program for video surveillance systems

Level of difficultyEasy
Reading time3 min
Reach and readers3K

Developers of smart cameras, smart DVRs, and neural-network video analytics for surveillance systems need AI models capable of operating in real-world street conditions. Out there, nobody walks around with professional cameras, carefully adjusts angles, sets up lighting, records without compression, or follows the common sense taught in cinematography textbooks.

Of course, Gambit can be used for many other tasks, but its main focus is the convenient collection of material FROM video surveillance systems and dataset annotation specifically FOR video surveillance neural networks.

Gambit is not designed for polished photos and Internet reels. Quite the opposite — it is intended for low-quality surveillance archive footage. At SpesLab, we call this kind of content “wild.”

If a person is far over 20, then he has already accumulated a huge film library of his life, as well as videos from friends, relatives, and from his place of work… It is no longer possible to find someone or something specific there. Recently, I was preparing a video compilation for my daughter's anniversary – I spent a week. The media is all the more overloaded with video archives. And every day, millions of terabytes of video content appear in the world. And this is in the era of BIG DATA.

Publish and Play


There exist two main functions of WebRTC operation on the server side in the field of streaming video: publishing and playing. In the case of publishing, the video stream is captured from the web camera and moves from the browser to the server. In the case of playing, the stream moves in the opposite direction, from the server to the browser, is decoded and played in the browser’s HTML5 <video> element on the device’s screen.

A Brief History of Video Conferencing

Video conferencing systems, so familiar to us today, have come a long way — more than a hundred years passed from fantastic ideas inspired by belief in unstoppable technical progress to the first mass implementation of video conferencing systems. A lot of dramatic events have come along the way. The way to success wasn’t easy at all.
