Digital Surveillance Recorder RVS-DVR-X provides
long-lasted video data recording on an internal
hard disk. The recorder is able to record video
data for several months from up to four different
video sources, colour and b/w. There are used
innovative digital video storage and image compression
technologies to operate as a stand-alone recording
device or as a memory component in Close Capturing
Television (CCTV) security system.
Original video compression technology provides
variation recording only. It does not record static
frames and invariable parts of a frame. Movement
events can be sorted and recorded according to
threshold parameter, what is very useful in crowded
places when RVS-DVR-X will not record constant
movement. The technology provides the achievement
of up to 200x rate of compression, saving hard
disk space and lasting of recording time.
Alarm sensors, switched in alarm joints, allow
the RVS-DVR-X to manage with the recording process.
Special photo mode provides high quality photo
image. Alarm sensors together with photo mode
provide with the most important and useful information
on an event.
RVS-DVR-X is suitable for all surveillance applications.
Important Features
- Continuous video signal recording (with
time- and date-stamp) from up to four CCTV
cameras(color or b/w) on a internal hard drive
with possibility of simultaneous playback
over digital interface without productivity
loss: full duplex.
- The algorithm of video image compression
provides the storage of a varying image parts
only: picture comparing proceed. The 200x
compression can be reached.
- Alarm sensors (of a security warning system)
can be connected to every channel to activate
recording.
- Corresponding video channels can be activated
on an excess of the “motion activity threshold”
in a frame’s zoom.
- Signal dropping-out / resuming recording.
- Adjustment and reviewing via a PC parallel
port. Copies of selected video segments can
be archived at the local hard drive.
- Scaleable “activity diagram” with frame
fixing to date and time. A quick access to
any frame.
- The few video sources will be used and the
smaller observed area the larger frame rate
and recording time will be reached.
