Benefits of deploying drones as 1st responders
Drones are un-piloted aircraft or missiles controlled by an operator from the ground. They were originally designed for military reconnaissance purposes, away from the public eye.

Road Salting
Regions that regularly or seasonally experience temperatures below the freezing point of water will have their roads treated with halite, more commonly known as rock salt.

The dangers of gases
Most gases fall into one or more categories of inert, flammable, oxidizing, toxic or cryogenic. Those that are classified as inert or reactive generally don't undergo chemical reactions under particular conditions and include nitrogen and argon.

About Stray Voltage
Stray voltage appears where there is electric potential between two objects that would normally not have any voltage difference between them. Metallic electrical equipment enclosures or street furniture may possess large voltages due to a variety of faults in the electrical distribution system.

Factors affecting gas sensor selection
Gas sensors are available in a variety of technologies, each having distinct advantages and limitations for their individual applications. Some of the more common types are electrochemical, catalytic bead, infrared and metal oxide. CNIguard’s Ian Courtney examines the relative merits of the different gas sensors available.

CNIguard embraces Narrowband IoT (NB-IoT)
Narrowband IoT (NB-IoT) is a category of low power wide area networks (LPWA) designed to support the deployment of Internet of Things (IOT) devices. The specification was developed by the Third Generation Partnership Project (3GPP), consisting of seven telecommunications standard organizational partners.

Infrared camera sets Sentir apart from competition
Infrared (IR) and its ability to ‘see’ in the dark can be deployed as part of a broad spectrum underground monitoring system where infrared can detect overheating electrical wiring or materials involved in spontaneous, low level combustion.

Con Edison deploys our Sentir virtual inspection system
Sentir, a new condition monitoring system developed by CNIguard, is defining the solution to prevent and mitigate manhole events, a utility problem that occurs more often than most may think.
