truVision DVR 31 User Manual 1
Chapter 1: Product Introduction
Product Overview
This is the truVision DVR 31 User Manual for models:
• TVR-3108-1T
• TVR-3108-2T
• TVR-3116-2T
• TVR-3116-4T
• TVR-3116-6T
The truVision DVR 31 is a network digital video recorder developed for digital
surveillance. The truVision DVR 31 uses an embedded microcontroller unit
(MCU) and Linux operating system, combining the most advanced technology in
video and audio encoding/decoding, hard disk recording, and TCP/IP
communication. The DVR’s firmware is stored directly into the memory, making it
more stable and reliable.
The truVision DVR 31 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 solution.
The DVR 31’s pentaplex operation enables users to view live video, search and
play back any recorded video by date and time or by event, and back up the
configuration and video data, without interrupting the ongoing DVR recording
process.
In addition to the new H.264 compression mode, the DVR’s graphical user
interface also optimizes the monitoring controls of the unit.
The DVR 31 comes with remote viewing and configuration software already
installed. This software includes a Web browser plug-in, allowing users to view
live or recorded video images, and enabling remote configuration. The remote
software is stored in the DVR 31 and deployed over a LAN, WAN, or Internet
connection to remote Windows-based computers. This simplifies the installation
and maintenance of the software components because all remote users are
using the same software, which comes from the unit.

When installing your product, consider these factors:
• Ventilation
• Temperature
• Moisture
• Chassis load
Ventilation: Do not block any ventilation openings. Install in accordance with the
manufacturer’s instructions. Ensure that the location planned for the installation
of the unit is well ventilated.
Temperature: Consider the DVR 31’s operating temperature (32 to 104°F, 0 to
40°C) and humidity specifications (10 to 90% relative, noncondensing) before
choosing an installation location. Extremes of heat or cold beyond the specified
operating temperature limits may reduce the life expectancy of the DVR 31. Do
not install the DVR 31 on top of other hot equipment. Leave 1.75 inches (44 mm)
of space between rack mounted DVR 31 units.
Moisture: Do not use the unit near water. Moisture can damage the internal
components. To reduce the risk of fire or electric shock, do not expose this unit to
rain or moisture.
Chassis: Equipment weighing less than 35 lbs (15.9 kg) may be placed on top of
the DVR 31 only if the DVR 31 is placed on a shelf and not rack mounted.
Be sure to power off the unit before making any connections. In order to prevent
the unit from losing data and system damage that may be caused by sudden
power, use of an uninterruptible power supply is highly recommended.
Note: Do not remove the rubber feet, and always leave a space for air ventilation
on the unit’s bottom side.
Unpacking the DVR 31 and its accessories

truVision DVR 31 User Manual 7
Chapter 2: Installation
Connecting required devices
Before powering up the unit, cameras and a main monitor should be connected
to the unit for basic operation. If needed, connect a spot monitor for displaying
full screen video of all installed cameras in sequence.
Note: You can attach an extension to the RS-485 port on the back panel.
Connecting external devices
When connecting external devices to include as part of the entire system, such
as a USB drive or any other USB devices, connect those devices only when the
unit displays live view. The DVR 31 recognizes external devices only after the
unit has gone through the initialization process.
