Chapter 1 Overview
Multiple Protection
In case of the failure of the DV tape drive, recording
operation continues on the built-in hard disk.
Conversely, the HSR-1/1P/2/2P records the image data
directly onto the DV tape if the hard disk fails. (In
some cases, some of the data may be lost.)
For additional protection, the HSR-1/1P/2/2P always
checks whether data is accurately recorded onto a tape.
If a recording failure is detected, the HSR-1/1P/2/2P
re-records the same data onto the tape.
Less Space Required
Compact body
The HSR-1/1P/2/2P features a compact body and is
similar in width to a 14-inch monitor.
Compact storage medium
Using DV cassettes of only 1/3 the volume of VHS
cassettes means your tape library takes up much less
space.
System Versatility
16 Camera inputs
The HSR-1/1P/2/2P has four camera inputs as
standard. Up to three optional HSRA-11, four-input
boards can be installed, so up to 16 camera inputs can
be provided.
Built-in multiplexing capability
The HSR-1/1P/2/2P has built-in multiplexing
capability, which allows independent recording and
monitoring. There is also a choice of various
monitoring patterns by freely assigning multiple
cameras to a single monitor.
Output for a second monitor
The HSR-1/1P/2/2P has two monitoring outputs A and
B, for which output images can be independently
selected. For example, it is possible to monitor the
image from one key camera on the B monitor, while
checking playback on the A monitor.
Flexible camera assignment
There are five preset recording modes, which can be
flexibly combined with your choice of picture quality
mode, tape length, recording time, number of camera
inputs and the recording cycle of each camera. This
feature allows you to assign cameras as you like. It is
possible, for instance, to record from all the cameras in
High mode during the day and then select some of these
cameras to be recorded from in Super mode at night.
RS-232C interface
The HSR-1/1P/2/2P is equipped with an RS-232C
interface for communication with external equipment
such as a personal computer, to facilitate machine
control, and user data read/write. You may also use this
port for connecting the optional SNT-V304 video
network station.
37-pin parallel port
The HSR-1/1P/2/2P has a 37-pin parallel I/O interface,
whose pin functions can be freely configured for a
particular application.
Recording/Playback Systems Not
to Miss Any Important Scenes
Playback During Recording
(HSR-2/2P only)
You can check the latest recorded images by reversing
the recording for the desired length of time (from 1 to
99 minutes) without stopping recording in progress.
When checking, you can also search for a specific
image by using the time search and alarm search
functions. Images recorded on other cassettes can also
be played during recording by changing cassettes.

Flexibility in Alarm Recording modes
To capture more and even sharper images, the HSR-1/
1P/2/2P not only changes its recording mode to the
higher refresh and higher picture quality mode on
alarm, but also performs interleaved recording, which
accelerates the recording cycle of the camera in alarm
status.
It can also record images from the camera in alarm
status only for a preset duration. In addition, since
alarm and timer recordings can be combined, the HSR-
1/1P/2/2P can be set to normal recording mode during
office hours and set to alarm recording at night.
Continuous recording function
The recorder can continuously record images, even
while you are changing or rewinding the tape, so you
don’t have to worry about the breakup of a recording.
Sophisticated security function
The key-lock function may prevent accidents, such as
inadvertent break-off of important recording.
For higher security, you can specify passwords at three
levels.
Watermark
Using an original watermark system, the HSR-1/1P/2/
2P can identify image data that has been artificially
altered. When alteration is detected, a message is
displayed on screen.
Intelligent search functions
Time search/alarm search
You can easily locate the picture from a specific date
and time.
With a tape on which alarm recordings have been
made, you can locate a specific picture after checking
the list of those recordings.
Variable-speed search with a Jog/Shuttle dial
By connecting the optional SVRM-100A remote
control unit, noiseless picture search can be carried out
using its Jog/Shuttle dial.
Rec End search
The recording end point on a tape can be easily
located.
Quick recording start
The HSR-1/1P/2/2P can start recording the moment
power is turned on. This allows immediate recovery
of recording after a power failure.
Pre-alarm recording
Thanks to the Pre-alarm recording capability,
recording can be started before catching a trigger
signal, thus chances are you’ll have the information
you need on tape
High-quality frame recording
By selecting Frame Rec mode, you can record a single
frame in response to an alarm in Hyper mode, which
provides higher resolution than Super mode.
Power-failure backup function
The HSR-1/1P/2/2P is equipped with a protection
circuit (memory-backup circuit with a rechargeable
battery) to prevent loss of video data caused by power
failure.
If the power fails during recording, the protection
circuit activates, and stores video data for 24 hours.
When power is restored, the unit automatically
resumes recording mode and records the stored video
data on the tape.
Notes
• At least 24 hours with the power on is required to
fully charge the battery.
• Several frames captured immediately before the
power failure may be lost.
