Vess A-Series

Open Storage Platform for Video Surveillance

Optimized for surveillance

Vess NVR server and storage appliances are custom built to offer the highest levels of performance for IP video surveillance. Promise is active in all of the key video surveillance segments and is able to provide a solution for deployments of any size.

Reduces costs and complexity

Vess NVR appliances reduce support and equipment costs because there is no separate RAID storage unit to manage, eliminating the need for a server, controller cards, external cables, and a separate storage enclosure. Additionally, Vess NVR appliances reduce interoperability conflicts caused when integrating different hardware.

Certified by surveillance partners

Vess NVR appliances are fully compatible with a range of IP cameras and VMS from vendors including Aimetis, Axxonsoft, CamIQ, CSVi, Digifort, Genetec, OnSSI, SeeTec, Sony and Milestone.

Highly integrated with smooth scalability

An SDK library is provided for VMS UI and management integration. Plus, Vess supports the Milestone VMS plug-in enabling it to be managed via the XProtect interface. Additionally, you can easily expand via iSCSI by adding Promise external storage.

SmartBoost Technologies

A collection of unique features designed to provide the highest level of service and overcome performance bottlenecks to allow Vess NVRs to handle a higher number of IP cameras than competing solutions.

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 – takes all worries away by proactively detecting when PSU, controllers or HDDs are going into critical condition and automatically notifying Promise support so the customer can be contacted, spare parts can be sent out or the unit can be powered up after an outage - vitally important in environments that cannot risk downtime.

Sequential Pattern Recording - eliminates the heavy workloads caused by random write patterns as this feature monitors recording patterns and collects data in the cache buffer and only writes data to the drives once a full stripe is ready. This creates a sequential recording pattern which offers the smoothest performance.

Simplified planning

With just a few clicks of the Promise online planning tool you can easily get the whole picture of what you need for your project, including the NVR and storage requirements, how to configure the servers and storage and see a topology of the interconnecting systems with the most popular and recommended settings.
