Specifications

Reduction of Expenses
Unlike existing VCRs, this unit uses digital HDD recording, thus
saving cassette handling time and freeing up space normally
needed for tape storage. In addition, its compact-size body re-
quires less area for an installation.
Compact half rack width
Digital recording is now available in a compact package of
210mm (8.27inches) in width, which makes it possible to install
two DSR-M804 units side-by-side in a 19" rack. It is an ideal solu-
tion for the limited spaces of convenience stores, or casinos
where a large number of DVRs are needed.
Multiple Recording Methods
Available modes are “Normal recording” for surveillance images,
“Timer recording” for predefined recording hours, and “Alarm
recording” with an external alarm signal. The latter two can be
combined to perform multiple recording functions.
Timer recording
Uniform daily programming and independent programming for
each day of the week are both available. Moreover, holidays
can be input by specifying the date and month for which Sun-
day programming is applicable.
Alarm recording
When an alarm signal is received from an external sensor,
DSR-M804 will automatically start recording in the mode pre-
determined by the user.
Motion Sensor
DSR-M804 comes with a built-in motion sensor. Different set-
tings can be made for each camera image independently. The
sensor can detect moving objects within the screen by picking
up changes in brightness. The user can use this feature to trig-
ger an alarm recording.

(NTSC) recording with “HIGH mode” picture quality. Moreover,
the unit has an expansion bay for an additional HDD; another

recording time. The user can also use the optional HDD for mir-
ror recording* to back up important data. (For further details
about HDD expansion, contact the place of purchase.)
*Mirror Recording
DSR-M804 each come with one HDD unit. By adding an optional HDD of the
same capacity, it is possible to record the same video on two HDDs, thus allow-
ing for a backup.
Audio Recording with 4 Inputs
DSR-M804 comes with audio ter-
minals for four inputs and one out-
put. The implementation of
MPEG1 Audio Layer2 allows play-
back of clear sound. Audio can be
easily downloaded over a network,
along with video images.
During
recording, however, CH1 and CH2
are mixed and recorded on the
same track. The same applies for
CH3 and CH4.
