Hikvision NVRs are devices used to operate professional security systems. They are designed for high reliability of operation and easy to use, but containing many advanced functions system. The DVR menu allows you to manage it and the entire monitoring system. Advanced functionalities such as detection systems, content analysis or the ability to set privacy zones allow you to create a perfectly matched system. Motion detection can only allow for recording when an intruder has appeared in the area or triggering various alarms such as e-mail notification or triggering an alarm output. Setting privacy zones will allow you to exclude from the preview areas that could violate the privacy of others (for example, windows of other buildings).
Another property of the recorder is dual streaming. The image is streamed in two at a higher and lower resolution at the same time. A higher resolution is used for live view in full-screen mode and data recording, and a smaller resolution is used for split-screen preview (optionally for recording material). Hikvision DVRs are also characterized by multitasking, i.e. they are tribrid. This means that they can perform many tasks at the same time: live preview, playback of saved data, archiving and sharing data via an Internet connection. The parameters of each recording channel can be configured separately: resolution, bitrate or image quality. Thanks to this, we can keep in memory a better image from the preview of more important objects, and reduce the quality of recordings from general previews.
