Stores important video for longer
Secure Storage. Secure Video.
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 AXIS 2460 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 AXIS 2460 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!
Example
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 fps

Average image size = 8kB
 1 x camera

4 x 40GB IDE HD

Continuous low priority recording, and a single top priority
alarm recording with 30 minute duration
In security applications, consistent quality of the recorded image
is vital. With three different resolutions available per connected
camera, the AXIS 2460 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 AXIS 2460 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.
AXIS 2460 has three levels of user/password protection, with built-
in firewall functionality based on IP filtering for secure remote
system access over TCP/IP networks.
