There are 14 names in this directory beginning with the letter V.
A shorthand to combine Vehicle-to-Vehicle (V2V), Vehicle-to-Infrastructure (V2I), and Vehicle-to-Anything.
Vehicle-to-Infrastructure (V2I)
The communication of smart cars and commercial vehicles with surrounding sensors, such as signal phase and timing (SPaT) information.
Vehicle-to-Vehicle (V2V)
Using a region of the 5.9 GHz band, V2V systems allow vehicles to communicate with each other and with roadside stations. Networks of vehicles can help avoid congestion, find better routes, and aid law enforcement.
Vehicle-to-Vehicle Communication (V2V Communication)
The wireless transmission of data between motor vehicles.
Vibration Sensing
A MEMS concept referring to the detection of periodic acceleration and deceleration. Typical applications include structural health monitoring, acoustic event triggering, and seismic equipment.
Video Motion Detection (VMD)
A technology that analyzes image data and the differences in a series of images. VMD makes event-driven video surveillance possible, but the potential for false positives creates challenges in storage and alarm verification.
Video Surveillance as a Service (VSaaS)
A managed data service that transfers the monitoring and storage of video to the cloud. VCaaS streamlines security operations by centralizing IT and requires no capital investment in servers but has heavy bandwidth requirements.
Virtual Power Plant (VPP)
In a virtual power plant, different, decentralized power generating plants are connected and are monitored and controlled from a single control center. This way, virtual power plants can integrate smaller energy providers
Virtual Sensor
These sensors use data to gather information that would not be measurable by a single device. This way they can attain information that can’t be measured directly.
