Mitsubishi DX-TL1600EM Digital Video Recorder

Note: This system has been superseded by the new Mitsubishi range including the DX-NT400E, DX-NT950E & DX-TL2500E models, which have many new features and considerably higher storage capacities.
All DX-TL1600 series systems have fully functional remote access via the Ethernet port, but the interface is not as advanced as the current generation. Therefore we would advise customers wanting to regularly use their system remotely from their personal computers to look at one of the newer models, which have a very powerful user experience available via the included NetHunter software application.
From time to time we get pre-owned units of this popular model back from customers who upgrade to newer models and these are ideal for customers who like to use the high quality digital technology offered by Mitsubishi, but are unable to afford the latest Mitsubishi models.

  • Entry level, user friendly, high resolution 16 channel digital video recorder with transmission of live and recorded images over Ethernet networks.
  • Enhanced motion detection functions for recording only when movement occurs.
  • Digital high-definition 16-way live screen and playback to assure the security of your site.

Recording interval setting for each camera

  • It is possible to set each camera with any one of 5 recording intervals to suit the monitoring application.
  • During an alarm event the recording interval can be switched to provide a shorter record interval for the camera where the event is detected.
  • Alarm events from 2 cameras can be managed simultaneously.

Copy and backup options

  • The Mitsubishi DX-TL1600EM Digital Video Recorder is compatible with HDD, ZIP drive, DVD-RAM and DDS drives.
  • Back up can be performed without stopping recording.
  • An alarm recording may require longer storage than a normal recording, in this case the alarm backup mode can automatically transfer the alarm data to the back up drive connected to the SCSI socket. This will ensure that the important alarm data is isolated from the normal recordings.

Motion detection prevents unnecessary recording and enhances playback efficiency

  • Differences between sequential frames are used to trigger recordings so that recording time is maximised.
  • No external sensors are required leading to reduced installation cost.
  • The detection area and sensitivity can be set for each camera.

Network Interface for efficient monitoring with a personal computer.

  • All Mitsubishi DX-TL1600 series Digital Video Recorders come with built in network capability. The system can communicate with a PC using an Ethernet connection and the included remote viewing software (DX-PC3).
  • This powerful function allows the review of recorded events and live images remotely, along with selection and viewing of multiple cameras just as though the operator was on site

16 Input Multiplexer function for efficient monitoring with multi-screen displays.

  • Full screen, 4, 9 or 16 pictures can be selected for display on the monitor.
  • The built-in multiplexer, continues to record all camera sources regardless of what is selected for display on the monitor.
  • The multiplexer can also provide extra monitoring efficiency by automatically switching display modes at the time of a motion detection alarm.

Advanced digital recording and playback functions

  • Date & time search, alarm list search, skip search, index search and camera filtering search for high speed retrieval of recordings in less than 0.7 seconds. 
    Jog & shuttle with dual function control for scene selection and easy menu operation.
  • Forward and reverse slow motion, frame by frame, quick playback and still frame.
  • Pre-alarm images are continuously stored so that recording can be started in advance of the alarm trigger.
  • Image files carry a 'watermark' that identifies it as an original image, free from tampering. 
    All set-up parameters can be password-locked to prevent accidental or intentional tampering.
