Intelligent Video System (IVS):

Intelligent Video Surveillance involves the processing of the recorded video. IVS is designed to detect events with pre-defined criteria. Appropriate configuration of the function on the DVR level allows continuous analysis of the recorded image and enables very quick detection of unwanted events. The functions include: virtual line crossing detection, zone intrusion detection, object disappearance/appearance detection, face detection, camera alignment change and lens painting detection, and sound detection.

Smart Search:

Smart search allows you to search through your recordings. During playback, you define an area of interest and search for recordings where motion detection has occurred in the defined area. The most important feature of this function is that you do not need to know and program the area when programming the system. The user defines the image only during playback.

ANR:

With this function we are assured of continuity of recordings in case of failure, disconnection or loss of connection occurring between the camera and the recorder. The system works by automatically detecting a problem with the network and securely recording to a microSD card inside the camera. After the failure is over, the recordings are automatically synchronised and in case of shortage the DVR will download the missing fragments directly from the camera.
