DVR2460 Network Digital Video Recorder
Digital video. Recorded locally. Viewed globally.

Sophisticated, flexible yet brilliant in its simplicity, the award winning DVR2460 Network DVR takes digital video recording to a completely new level of advancement. Connect it directly to a TCP/IP network and remotely access digital video and system administration tools, using a standard web browser. Accommodating up to four analog cameras with or without Pan/Tilt/Zoom, it has its own built-in web server and is completely self-maintained. No need for tapes, tangles or expensive maintenance!

Retaining important video sequences for longer than any other DVR solution, the DVR2460 offers an almost inexhaustible local recording resource for security video - using revolutionary APViS™ Prioritized Video Storage technology*. Used as a single stand-alone system for a small business, or as an autonomous component within a globally distributed video surveillance system, the DVR2460 is perfect for use within large retail chains, franchise operations, or any business that requires convenient network access to live or recorded surveillance video.

Innovative APViS™
Stores important video for longer

Older video recordings can contain vital visual evidence. But when the hard disk in any conventional DVR is full, it is simply the oldest recordings that are indiscriminately erased in order to make room for new ones. It's standard FIFO logic: the First image In is the First one Out. But, is this really the smartest way of managing modern surveillance video?

Using innovative APViS technology, the DVR2460 Network DVR makes more efficient use of valuable disk space to preserve video recordings for longer. Flexible event management makes it possible to define up to 100 separate events, combine scheduling with alarm inputs, and by intelligently using event and alarm data, it cleverly differentiate between 'important' and 'less important' video.

Using these criteria, the DVR2460 is able to store top priority video sequences at their original recording rate up to four times longer than any conventional FIFO storage solution - and up to sixteen times longer using an incrementally reducing framerate. In practical terms, this can be the dramatic difference between having the evidence - and not having it!


The graph below displays typical storage times for APViS 'Extended' recording mode versus conventional 'FIFO' storage, based on the following configuration:    
Original recording frame rate = 10
Average image size = 8kB
1 x camera
4 x 40GB IDE HD
Continuous low priority recording,
  and priority a single top alarm recording with 30 minute duration

Secure Storage. Secure Video.

In security applications, consistent quality of the recorded image is vital. With three different resolutions available per connected camera, the DVR2460 records in Motion JPEG format and guarantees consistent high-quality on each and every image.

The unique use of database mirroring and distributed video storage on all available hard disks allows the DVR2460 to tolerate hard disk failure without losing vital parts of video recordings. The practical implication of hard disk failure is a relative reduction in the frame rate of the recordings.

DVR2460 has three levels of user/password protection, with builtin firewall functionality based on IP filtering for secure remote system access over TCP/IP networks.

Flexible Network Configuration
Stand-alone or components within globally distributed systems

With over 90% of archived video recordings often never even looked at, decentralized video recording avoids unnecessary network utilization and makes sense when network bandwidth is limited.

A DVR2460 Network DVR has its own built-in web server and is securely accessed from any remote geographical location using Microsoft Internet Explorer.

By deploying a single DVR2460 in each remote site, organizations now have the opportunity to build large globally distributed video storage systems, whereby users can view video and control Pan/Tilt/Zoom as well as managing recorded material from anywhere over TCP/IP networks.
