Availability / Time to First Reduction
 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
Recording Conditions – Event Set-Up
 Always
 Scheduled
 At alarm
 Manually
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!
Customers and applications #1
 Small-scale businesses requiring an
easy to operate and remotely
available monitoring and/or
surveillance system:
 Small retail shops (loss prevention and
monitoring)
 Gas stations (loss prevention and
monitoring)
 Small workshops (employee/production
monitoring)
Customers and applications #2
 Larger corporate organizations
requiring a centrally administered
remote monitoring and/or
surveillance system:
 Retail chains/franchises (loss
prevention)
 Telcos and ISPs (technical facilities
surveillance)
 Public service providers (monitoring of
water, gas, power supply, etc. systems)
