“AI capabilities are just beginning to make an impact but expected to see wider adoption as the industry learns more about the possibilities.”
lic address system to play an automated message over a nearby loudspeaker with instructions to move the object. Alternatively, this same system setup can help users enforce no-parking zones – triggering a message when a vehicle parks or loiters in a fire lane. While these situations are certainly safety concerns, the solutions also reduce the risk of violations and fines when these events occur.
In many larger office buildings, the elevator lobby is the main artery to move people. AIoT cameras can detect crowds in these areas and then trigger other systems to redirect traffic during peak congestion. Making that process faster can have a major impact on the productivity of a workforce and the perception of the accessibility of a building.
Retail stores. AIoT cameras can count the number of people entering and exiting a store to provide operations managers with customer traffic data. This information can help managers under- stand peak days and times and ensure sufficient staffing to opti- mize the quality of customer service.
Smart infrastructure. On roadways, AIoT cameras can detect a vehicle traveling in the wrong direction and trigger a roadside unit to notify the wrong-way driver as well as other nearby mo- torists through dynamic message signs, flashing beacons, or by broadcasting safety messages to smart vehicles. These capabili- ties provide a real-time safety solution and enable drivers to take action earlier. This same type of system can also alert to slow or stopped vehicles, queues at exit ramps, objects in the road, and other traffic events.
Video sensors can also classify objects as cars, trucks, bicycles, and pedestrians, and detect speed and trajectory – continuously collecting real-time data. Armed with this valuable information, city traffic planning directors and senior traffic engineers can analyze flow patterns on networks of roadways for implementing new policies that result in safer and more efficient intersections.
The latest software founded on deep neural network-based video analytics can even distinguish and classify vehicles in congested scenes. The software can count overlapping vehicles queued at traffic lights or in dense traffic jams, while ignoring common disturbances caused by vehicle headlights, shadows, ex- treme weather, and sun glare and reflections. With high precision detection, accuracy levels extend beyond 95 percent.
TRANSPORTATION
This same concept applies at the airport curbside for passenger drop-off and pick up where vehicle-parking time is restricted. AIoT video systems can detect and alert law enforcement to ve- hicles parked for longer than the maximum time limit.
In lots, cameras can count the number of open parking spaces, or track ingress and egress, and relay this data to the video and parking management systems. Sharing this information and alter- native parking locations on a dynamic message sign can help drivers
find open parking faster to reduce traffic congestion and emissions. They can also gather data at airports, where traffic flow and plane status awareness is critical. Data collected could include in- formation on how long an airplane parks at a terminal, the time it takes to load passengers’ luggage, or how long it takes to refuel a plane. This information helps speed the turnaround time for passengers and aircraft, improving efficiencies at the airport, and
reducing costs for airlines.
TRANSFORMING DATA INTO INTELLIGENCE
Capturing the vast amount of raw data and funneling it into a platform that transforms it into intelligence is essential. This transformation is key to enabling both automated and human decisions. As AI technologies continue to grow, applications are quickly evolving, powering new abilities every day.
AIoT software supports informed decision-making by consoli- dating and augmenting data from multiple cameras into actionable insights. Users can establish a decision center using software, giv- ing them a single, clear dashboard for evaluation. Dashboards can help users identify unforeseen, unwanted, or future situations faster and more reliably – enabling a response before potential situations occur. They can also deliver business intelligence beyond security.
Capturing data and using AIoT cameras to trigger other sys- tems requires high-quality images to ensure reliability and accu- racy. Quality images are essential even in situations where objects are moving, or there are poor lighting conditions or other adverse conditions. If image quality is lacking, the accuracy of the data is at risk, as is any video evidence.
AI technology now in used must also be robust enough to dif- ferentiate between genuine events and false triggers such as snow, moving trees, rain, hail, and water reflections that can make video data difficult to interpret. It should also be able to retain informa- tion on user-defined objects and situations and refer to these new learnings when processing scenes.
EXTENDING AI TO AUDIO
In some cases, video sensors alone may not be enough to provide the needed detection and situational awareness for critical events. Combining audio and video sensors with AI can facilitate a faster response. Audio analytics built in to the camera can recognize and identify the unique audio signatures of sounds like glass breaking, aggressive voices, and gunshots. It can assist operators in detecting, classifying, and locating the direction of the source of an audio event to help security personnel quickly know where and how to respond.
As the proliferation of AIoT video systems grows, integrators must anticipate how they will change user preferences. System inte- grators who understand the full potential and capabilities of AIoT products and software can provide their cus-
tomers with predictive, sustainable, and trusted
solutions that address the challenges users face
in their businesses and organizations.
