UR5 is i3's compact and affordable NVR solution, supporting up to 32 channels of video recording. The UR wall-mount chassis boasts exceptional durability and versatility. Two large industrial chassis fans ensure proper air circulation preventing the unit from overheating. The UR5 NVR Server features wall-mount/desktop chassis designed for installations with limited space. Windows 10 IoT operating system comes on a Solid State Drive for added stability and fast boot-up times. Running on Intel i5 CPU, the UR5 powers all its components with a 400W power supply. The 2 NICs allow you to keep your IP cameras on a separate network via a Gigabit switch, such as i3's S244 or S81, while accessing the Internet through the second NIC without impeding your network. For video backup use the DVD recorder or the USB (on the front panel) for easy-to-use external USB storage. UR5 supports up to two (2) storage 3.5" SATA hard drives, up to 18TB each, for a total of up to 36TB of video storage. For even longer video retention or recording capacity, i3's iS416 external hard drive device can be purchased.
