The Vess A2230 12TB 6-Bay NVR from Promise Technology is built to offer high levels of performance for IP video surveillance and is well-suited for small deployments such as retail stores, clinics, classrooms and gas stations. It supports up to 35 IP cameras, is powered by a 2.0 GHz Intel Celeron J1900 Quad-Core processor and 8GB of DDR3 RAM and has a capacity of 12TB that is split over six 2TB SATA 3.5" hard drives, each of which utilizes one of the NVR's six drive bays. A 64GB mSATA SSD is built-in and hosts the operating system and there are also two Gigabit Ethernet ports, four USB 3.0 ports, two USB 2.0 ports, HDMI and VGA video outputs, three RS-232 serial ports and support for RAID 0, 1, 1E, 3, 5, 6, 10 (0+1), 30 and 50. For those who wish to increase the storage capacity of this NVR, expansion is possible through iSCSI and multiple JBOD expansion enclosures. The supported operating systems are 64-bit editions of Windows Embedded Standard 7 Runtime (WS7P) and Windows 10 and this NVR is powered by an internal 250W power supply that runs using 100~240 VAC at 50-60 Hz.
Reduce Costs and Complexity

Integrated with Smooth Scalability
Predictive Playback - utilizes idle recording times to monitor read patterns to predict where the next playback will be needed so the hard disk drives are not competing with the workload of the system.
Remote Active Service - proactively detects when the PSU, controllers, or HDDs are going into critical condition and automatically notifies Promise support so the customer can be contacted, spare parts can be sent out, or the unit can be powered up after an outage. All of these are vitally important in environments that cannot risk downtime.
Sequential Pattern Recording - eliminates heavy workloads caused by random write patterns by monitoring recording patterns, collecting data in the cache buffer and only writing data to the drive once a full stripe is ready. This creates a sequential recording pattern which offers smooth performance.
