64-Channel Prime Series Network Video Recorder (NVR) | Dual 4K HDMI & VGA Outputs | Advanced Video Storage & Reliability Features

The Uniview NVR504-64E-IQ is a professional-grade network video recorder designed to handle larger IP surveillance systems with ease. It supports up to 64 IP cameras, making it a strong choice for retail centers, corporate campuses, warehouses, schools, and multifamily properties where many cameras need to be recorded, managed, and viewed from one central device.

This recorder uses efficient video compression formats — Ultra 265, H.265, and H.264 — to help save storage space while preserving clear footage, so you get more recording time out of your hard drives.

For local monitoring and playback, the NVR504-64E-IQ offers two HDMI outputs and two VGA outputs. The first HDMI and VGA can work at the same time, and the second HDMI and VGA can also run independently — allowing you to display multiple live views or recordings on large screens without switching views manually.

Built-in ANR (Automatic Network Replenishment) technology helps ensure continuous recording even if network connections are disrupted — cameras with onboard storage will automatically replenish the NVR with footage once the network comes back online. It also supports cloud upgrades so that firmware and features stay current.

Compatible with industry standards like ONVIF and RTSP, this NVR works with mainstream IP cameras from Uniview and other brands, giving you flexibility when building or expanding your system. The unit handles up to 64 channels of video input, supporting a range of resolutions and playback options.
