The SRX-Pro U31-series industrial NVR Server is purpose-built for enterprise video surveillance, delivering the performance, scalability, and reliability required for demanding environments. Powered by Intel’s 13th Gen i7 processor, the U31 handles high-resolution video streams and multi-channel recording with ease. Its compact 2U rack-mountable chassis is designed for efficient installation and optimal internal airflow to support long-term reliability. Eight front-accessible drive bays support up to 20TB each, allowing for a total storage capacity of up to 160TB.The system is configured with RAID 0 for high-throughput video performance and streamlined recording. Dual Gigabit NICs provide flexible network configuration, keeping IP camera traffic isolated—using switches like i3’s S244 or S81—while maintaining separate Internet or corporate network access. The front USB port enables quick video backups to external storage. The U31 comes preloaded with Windows 11 IoT Enterprise LTSC and i3’s SRX-Pro software, and can also be deployed as a Video Pilot Matrix Server for advanced surveillance control and display.
