Axis Communications 2460 - Manual (Page 6)

Product Overview AXIS 2460 User’s Manual 6
Recordings - The AXIS 2460 allows continuous unattended recording to a hard disk. Live
images can be viewed while recording, administration can be performed at any time, and
playback can be started while other recordings are in progress. Digital image storage
eliminates the multiple-use degradation associated with video tapes.
• Remote access from any PC over the network
• Continuous, event/alarm, manual and scheduled recording modes.
• Records and displays events directly — no waiting for tapes to engage or rewind
• Event driven recording maximizes disk space by only recording when an event is detected.
• Instant video retrieval from recordings list
• Automatic removal of recordings older than X days/hours can be enabled
• Searchable Recordings List
• No glitches when changing tapes, or forgetting to change tapes.
Optimized Storage/reduction - The AXIS 2460 manages the recordings stored on its disks via
a system that makes the best use of the available space. A special reduction algorithm, the
patent-pending Axis APViS, ensures that the recordings you designate as "important" are
retained for much longer than when using a simple FIFO (First-in First-out) system. Instead
of abruptly deleting recordings, the reduction algorithm gradually reduces the recording’s
frame rate, thus saving on disk space and allowing the recording to be kept for much
longer. The reduction process is fully configurable and recordings can also be locked, thus
preventing any reduction.
Secure Storage - The AXIS 2460 ensures that no recordings are totally lost in the case of a
disk failure. This is accomplished by virtue of the fact that a recording consists of a series
of images that are much the same and which are distributed among all the connected hard
disks in a sequential fashion. If every fourth image is lost, this only means a reduction in
frame rate, not that all the information is lost. In this way, important surveillance video is
assured, even in the unlikely event of a hard disk failure.
As an example, if you have 4 hard disks and one of them fails, the reduction in frame rate
will be (100/4) %.
Built-in Video Player - No need for extra viewing software. Simply click on the desired
recording in the recordings list in your browser and the AXIS Video Player starts
automatically.
• Playback and forward/reverse search at adjustable speeds, or view frame-by-frame
• Playback by date/time, event and camera
• Playback by choosing a recording from the recording list
• Snapshots are easily saved, and AVI movies can be quickly created using the AXIS AVI Maker
ActiveX component (included).
