Search by Video Analytics
NVR server is equipped with two useful video analytics that can perform advanced search –
Motion and Tamper .
Motion
- Unlike the typical motion detection method, this motion video analytics algorithm can detect
a maximum of six regions in a view, including rectangle regions and polygon regions.
Tamper
- A camera that has been tampered with is not able to serve its purpose. To avoid this, NVR
offers an algorithm to detect whether any form of tampering has been done to a camera,
whether it be in the form of redirecting the angle of the camera, de-focusing the camera,
covering, or spray-painting the camera.
