The so-called “Video Motion Detection” (VMD), is a “standard” video analytic function based on the simple analysis of pixel variation. The cameras supporting VMD can detect changes that occur in their field of view, and generate alarms regardless to the object type. Provision-ISR standard video analytics functions:
The A.I. is based on a series of algorithms, or mathematical procedures, which work like a series of questions to compare the object seen with hundreds of thousands of stored reference images of objects in different angles, positions and movements.
The A.I. asks itself if the observed object moves like the reference images, whether it is approximately the same size height relative to width, if it has the characteristic two arms and two legs, if it moves with similar speed, and if it is vertical instead of horizontal. Many other questions are possible, such as the degree to which the object is reflective, the degree to which it is steady or vibrating, and the smoothness with which it moves. Combining all of the values from the various questions, an overall ranking is derived which gives the A.I. the probability that the object is or is not a human, a vehicle or an object.
Based on smart objects recognition technology, DDA VIDEO ANALYTICS allows the system to distinguish between human beings 2-wheeled vehicles and 4-wheeled vehicles.
The system triggers alarms or sends push notifications only when the desired object is detected and by doing so reduces annoying false alarms caused by shadows, light changes, shaking trees, or animals.
The camera detects a face in the scene and sends the face snapshot to the NVR which analyses the face and compares it to the ones included in the existing database in order to recognize the person. Provision-ISR second generation of IP cameras feature great performances. An Eye Sight (V2) camera featuring face detection is able to detect up to 10 faces in 60 milliseconds while a Smart-Face camera can detect up to 30 faces.
Until now, Face Detection was performed by the Camera and Face Recognition was performed by the NVR. Provision-ISR Smart-Face series includes All-in-One cameras performing both Face Detection and Face Recognition, taking the load off the NVR and acting as an independent gate operator or attendance clock.
