The TLR2168 is a full-featured, versatile 168-hour
time-lapse recorder designed for the most demanding security applications.
Offering the widest range of useable record and playback modes
in our line, the TLR2168 will perform flawlessly in almost any
CCTV application. It is especially suited for Multiplexer use.
Its 7-day record capability makes the TLR2168 a perfect choice
for applications requiring continuous coverage over a long period
of time with minimum tape changes. Recording modes include standard
VHS 2- and 6-hour real-time modes in addition to high-density
18-hour linear “real-time” recording.
The L18H hour mode uses triple-density recording
technology to increase the field-recording rate. This means a
field rate of 20 fields/ second with 24 hours of recording time
using T-160 VHS tape in the L18H mode, enough information for
most critical recording applications. Audio capabilities are included
in all these modes as well as the L24H mode. VHS-compatible time-lapse
modes available with the TLR2168 are L24H, 48H, 72H, 96H, 120H
and 168H. All but the L24H mode are capable of both SP and EP
(high-density) recording modes for increased field recording rates
using standard high quality T120 VHS tapes.
Programming menus appear on the monitor output
to provide easy setup of any of the programmable features. Menus
are even available with no active video input. A lock mode disables
all front panel controls, preventing any changes to the unit’s
programming or operation. The TLR2168 can also be programmed to
repeat record. This means that when the end of the tape is reached,
the unit will automatically rewind and begin recording again.
If an alarm is received at any time during recording, the unit
will stop at the end of the tape. The TLR2168 also has an end-of-tape
output that can be used to activate another recorder. With this
feature, multiple TLR2168s can be interconnected to increase the
record time capabilities of the system. A tape-use indicator displays
the number of times the same tape has been recorded in the repeat-record
mode to facilitate tape replacement and management.
In addition to the tape use indicator, an elapsed
time indicator enables the owner to monitor head usage to plan
for scheduled maintenance and replacement. Special playback features
include speed search and reverse playback. Using the front panel
jog/shuttle control, users can quickly search through the recording
in either direction, then easily switch to forward/reverse field-by-field
movement for detailed study. The TLR2168 also provides the ability
to search to the minute (in all modes) for a specific date and
time. Automatic Alarm Search is a programmable feature of the
TLR2168.
Index Search allows the operator to go to a specific
indexed alarm. Skip Search finds alarms during fast forward or
rewind; the VCR slows down to 2H or 6H speed for about four secons
when it finds an alarm, then resumes searching for the next alarm.
The TLR2168 provides a programmable clock pulse output that enables
it to be easily interfaced to Pelco’s Genex‘ series multiplexers
for automatic speed tracking.
