1-1 Major Features

1 INTRODUCTION
5Extended timelapse recording for up to 960 hours
Recording times are selectable from 2 hours (SP mode),
6 hours (EP mode) and 24/48/72/120/168/240/480/960
(Timelapse mode) (when T-120 tape is used).
5High-resolution recording
Delivers horizontal resolution of more than 400 lines
even in color mode.
*When a tape recorded on this unit is played back on
another VCR, noise may appear on playback picture.
5High-density recording (HDR) function
Using the EP head, the tape is advanced at a fine pitch
for timelapse recording. In this way, about three times
more information is recorded in the same period than in
conventional timelapse modes. While this results in
some degradation of picture quality, the increased
coverage allows you to analyze the development of a
situation in greater detail. The actual recording duration
on the tape is the same as that of an ordinary timelapse
recording (select with menu switch <HDR>).
5Alarm recording function
When an alarm signal is input in the Record mode, the
2/6-hour mode is automatically engaged. Alarm
recording time can be selected from 5, 10, 15, 30, 60,
120, or 180 sec., to tape end, or set manually.
An index code is automatically recorded at the start
point of the alarm recording for use as an alarm cue
signal. Alarm recording points can be accessed quickly
with the alarm search function.
5Sensor recording
Whenever an alarm signal is input in the Stop mode
(Stop, Timer Recording Standby or Operating Off
mode), the Record mode is automatically engaged.
5Time/date generator
Superimposes date, month, year, hour, minute and
second on the image during recording. Also allows you
to display the number of alarms, alarm time, and the
number of the power failures on a monitor.
5Timer-recording function
Up to 8 programs can be set for daily, weekly, or
weekday timer-recording. You can also set timer
recording for up to 16 days a year by specifying the date
(holidays, for example).
5Tape position search function
You can automatically search the start of an alarm
recording or search for a recording made at a specified
date and time.

Recording conditions (quality) can be checked at any
time during recording by pressing the recording check
button.

input can be output from the VCR.
