AXIS 2460 - Why?
The US security video recorder market alone was 2001 a $193M market with an estimated value of $277M in 2005 – at factory level
The US DVR market estimations will from the 2001 value of $36M increase to hold a $171M market in 2005.

Examples, approximate figures in days – 1 fps from four cameras.
Recording Modes - APViS
Normal Same as FIFO, i.e. oldest recording erased completely
no matter what priority
Extended Approximately doubles recording availability over
Normal
Extended Long Approximately five-doubles recording availability over
Normal
Max Store Time Regardless of recording mode, maximum store time of
recordings can be specified per camera to enable compliance with local legislation
AXIS 2460 features
Advanced alarm handling Up to 100 events, whereof 50
simultaneously active, can be defined
Recording frame rate can be automatically increased upon alarm
Pre-alarm buffer: recording triggered by event also includes video from just before the event took place
AXIS 2460 features
Triplex functionality; simultaneous Live viewing/Playback Recording Administration
Secure storage Recordings are striped on 2 or 4 disks If a disk fails, ¼ of the images are lost No complete recordings are lost Recording continues at full frame rate
Secure Storage
A method to reduce the impact of a hard disk crash or unexpected power failure
The AXIS 2460 writes images sequentially to all available disks
With for example 4 disks and in case of a disk crash, ¼ of the images of all recordings are lost, i.e. a 25 % decrease of frame rate is the only result and no complete recordings are lost
The AXIS 2460 uses a journaling file system (ext3fs) After a power crash, the AXIS 2460 self-repairs and
automatically resumes normal operation The recordings database is continuously backed up to all
available disks, but 1 minute of latest recordings may be lost
AXIS 2460 features
Built-in firewall functionality and user level access control (user name, password) Unauthorized stations can be locked
out from access
Three levels of users can be defined allowing different levels of access for different authorized persons
Axis – a smarter solution
Many DVR’s don’t allow simultaneous recording, playback, live viewing, and administration
The AXIS 2460 has this triplex functionality
Archiving is often done to CD-RW, tape, Jaz and so on
The AXIS 2460 creates AVI on the PC for archiving on any medium of free choice
Many competitors require client software for remote viewing
The AXIS 2460 has everything built in – even a complete Web server!
