Verkkovideonauhuri

Verkkovideonauhuri, also known as a network video recorder (NVR), is a digital video recorder that operates within a computer network. Unlike traditional DVRs that connect directly to analog cameras, NVRs are designed to work with IP cameras, which are digital cameras that transmit video data over a network. This allows for greater flexibility in camera placement and system scalability.

NVRs receive and store video streams from IP cameras, often compressing and encoding the footage for efficient storage. They typically feature a hard drive for recording, a user interface for managing cameras and playback, and network connectivity for remote access. Users can access the NVR's interface via a web browser or a dedicated application to view live feeds, review recorded footage, and configure system settings.

The primary advantage of an NVR system lies in its use of IP cameras. These cameras can be connected wirelessly or via Ethernet cables, simplifying installation and allowing for longer cable runs compared to the coaxial cables used with analog systems. The network-based nature of NVRs also facilitates remote monitoring, allowing users to view surveillance footage from anywhere with an internet connection. Additionally, NVR systems often offer higher video resolutions and more advanced features such as motion detection, object tracking, and analytics.
