SPECO TECHNOLOGIES 01/08 11
1. Overview
The DVR-4TN/ 8TN/ 16TN/ 16TS/ 16TT series unit is an integrated digital
video recorder that combines the features of a time-lapse audio/ video
recorder, a multiplexer, and a video server to create a single security CCTV
solution.
Its outstanding triplex+ operation enables users to view live or playback
recorded video, have remote access through network simultaneously while
recording other video, and to view previously recorded video instantly by
entering the time and date or selecting recorded video from the event list.
The total number of PPS (Pictures per Second) makes the main difference
among these models, shown as below table:
DVR-4TN/ 8TN/ 16TN DVR-16TS DVR-16TT
NTSC 120 pps 240 pps 480 pps
PAL 100 pps 200 pps 400 pps
The DVR-4TN/ 8TN/ 16TN/ 16TS/ 16TT series includes SpecoRemote™, the
remote viewing and configuration software that is a Web-browser plug-in,
which allows the user to view live, or recorded video images, and enables
remote configuration. The remote software is stored in the DVR-4TN/ 8TN/
16TN/ 16TS/ 16TT series unit and deployed over a LAN, WAN or Internet
connection to remote Windows-based computers. This simplifies the
installation and maintenance of the software components so all remote users
are kept up to date.

1.2 Product Application Diagram
Connect the unit with other devices as shown in the system diagram below to
complete a video surveillance solution. The figure also displays the
expandability and flexibility of this digital recording system.
2. System Setup
Priority notices and an introduction on system installation will be described in
this chapter. Please follow the instructions to operate the unit.
In order to prevent the unit from data loss and system damage that can be
caused by a sudden power fluctuation, use of an Uninterruptible Power
Supply (UPS) is highly recommended.

2.1 Position the Unit
Position/ mount the DVR-4TN/ 8TN/ 16TN/ 16TS/ 16TT series unit in an
appropriate, steady location and make sure the power is off before making
any connections. The area should avoid hindering or blocking the unit from
airflow. Enough airflow is needed to protect the unit from overheating.
The maximum allowable temperature of operating environment is 104°F/
40°C.
The unit utilizes heat-conducting techniques to transfer internal heat to the
case, especially to the bottom side of the unit.
NOTE: Be sure not to remove the rubber feet, and always leave a
space for air ventilation on the unit’s bottom side.
2.2 Selecting Video Format
The DVR-4TN/ 8TN/ 16TN/ 16TS/ 16TT series unit is designed to operate
under either NTSC or PAL video formats. Please contact a qualified service
person to perform the installation procedure.
2.3 Connecting Devices to the Unit
This section lists some important notices that should be read before
making any connections to the DVR-4TN/ 8TN/ 16TN/ 16TS/ 16TT series
unit.
NOTE: Connect short-term external devices, such as USB
ThumbDrive®, USB CD-RW, USB Hard Disk Drive, etc., only after the
unit is successfully powered up.
Connecting Required Devices
Before powering up, you should connect cameras and a main monitor to the
unit for basic operation. If needed, connect a call monitor for displaying full
screen video of all installed cameras in sequence.

User’s Manual
DVR-4TN/8TN/16TN/16TS/16TT Series
SPECO TECHNOLOGIES 01/08 15
Connecting Short-term Device
If you plan to install any short-term external devices, such as USB CD-RW,
USB Hard Disk Drive, etc, to the DVR-4TN/ 8TN/ 16TN/ 16TS/ 16TT series
and want to use them as part of the unit system, make sure those devices
are connected only after the DVR-4TN/ 8TN/ 16TN/ 16TS/ 16TT is
powered up. The DVR-4TN/ 8TN/ 16TN/ 16TS/ 16TT series unit can only
recognize the external devices after the power-up process is completed.
2.4 Rear Panel Connections
There are several connectors on the rear panel of the DVR-4TN/ 8TN/ 16TN/
16TS/ 16TT series unit available for installations. The following figure shows
the connectors by name and a detailed description of each connector follows.
There is one difference between the rear panels of different models;
DVR-4TN/ 8TN/ 16TN has two IEEE 1394 connectors and DVR-16TS/ TT has
one 1000M LAN Port instead, shown as below figures.
