A 16-channel NVR (Network Video Recorder) is a surveillance recording system designed to manage and store video from up to 16 IP cameras simultaneously. It connects through a network, offering high-definition recording, remote access, and advanced features like motion detection, video analytics, and smart playback. Many models support PoE (Power over Ethernet) for easier installation, as well as expandable storage and cloud backup options. A 16-channel NVR is ideal for medium to large-scale security setups in offices, warehouses, retail, and institutional environments.
