Surveillance Solution for Mid-Sized Businesses

Vess A3340 is ideal for small-to-mid-sized video surveillance installations; reliable, high performance, easy to deploy and maintain. Certified and verified by the most popular VMS in surveillance industry with proven installations worldwide. Offering more diversified combinations of Intel Core and Xeon CPU options to create a high performance solution that easily handles the various surveillance system demands. Vess A3340 models are available with a single Power Supply Unit (PSU) or redundant PSUs. A redundant PSU guarantees system function if the PSU fails. Data on the Vess A3340 and additional capacity Vess RAID Storage systems are protected by PromiseRAID

Success Story

Brand value and customer satisfaction are developed not only through the quality and functions of the product, but also by meeting the expectations of the customer. Because customers in Japan have particularly high expectations for quality, a system must be established to respond to that level of demand. However, enhancing cost competitiveness requires that quality be maintained at the same time that efforts are made to cut procedures and provide rapid service.

Why Promise Vess Storage Appliances?

The Promise Vess Series of Storage appliances are reliable integrated server and storage solutions for IP video surveillance. Vess Storage appliances are open platform solutions that can be deployed with any of the leading IP cameras and video management software (VMS) for installations of any size.

More Flexible Deployment with Linux OS Supported

  • Linux users now have more options for their surveillance system deployment. Promise Vess A Series supports Linux distributions on select Vess A models for surveillance networks running Linux-based VMS in the back-end system*.

*The supported Linux distributions is listed on the datasheet and please contact your channel partners if you need others.

All-in-One Server and Scalable Total Solution of Storage Appliance

  • Reduces maintenance and service costs.
  • Easily expand via iSCSI by adding Promise storage.

Purpose Built for Surveillance and Highly Integrated Capability

  • SDK library available for VMS UI & Management Integration.
  • Supports to develop VMS plug-in enabling it to be managed via VMS interface.

Simplified Management and Serviceability

  • Modularized design and One Plug Auto Service simplifies maintenance and tech support workflow.

Certified by Surveillance Partners

Vess A3340 storage appliances are fully compatible with a range of IP cameras and world-clasee VMS from vendors including Aimetis, Axxonsoft, Digifort, Genetec, OnSSI, SeeTec, Sony and Milestone..etc.
The strong partnership will insure the customers will enjoy the well-rounded integration and outstanding performance.

SMARTBOOST™ Technology

PROMISE proprietary SMARTBOOST™ Technology creates the most stable and high-performance storage solution for your surveillance system. Performance that can be limited by storage equipment bottlenecks is significantly improved by Promise SMARTBOOST™ Technology. With the optimized software features and Vess A Series has the best stability and storage performance with the best C/P ratio.

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 user the hardware status. A huge advantage in installations with site restrictions, such as banking, as it not only saves maintenance costs but also the headaches caused when outside support personnel need access to restricted areas.

Sequential Pattern Recording

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