Mitsubishi DX-TL2500E Digital Video Recorder

This DVR has been superseded by the new generation DX-TL4516E & DX-TL5000E units.

  • User friendly high resolution 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.

PC networking for Remote Monitoring and Control

  • Standard Ethernet connection provides live and recorded viewing on a networked PC using a standard web browser.
  • Network software applications DX-PC25E and NetHunter provide additional functions including dome camera control, remote set-up, password authentication, image download and playback of downloaded image files.

16 Input Multiplexer with full duplex operation.

  • Full screen, 4, 9 or 16 pictures can be selected for display on the monitor.
  • Dual monitor outputs can show different split screen arrangements simultaneously.
  • All connected cameras continue to record regardless of what is selected for display on the monitor.
  • Pictures from specific cameras can be displayed without recording in cases where recording the camera picture is legally prohibited.


  • 50 pps capture rate allowing between 25 PPS on 2 cameras down to 3 PPS on 16 cameras.
  • Playback can be performed without stopping recording.
  • Built in 250 Gbyte or higher drive plus two bays available for extra internal drives up to a maximum of 2.25TB (2,250GB).
  • Up to 12 Tbytes of external storage can be attached via SCSI

Alarm recording

  • Choose between 3 alarm recording modes:
  1. Alarm Channel - full 50PPS recording capacity is utilised in recording the alarm event and normal recording stops.
  2. Alarm Plus - Alarm recording and normal recording operate at their desired levels.
  3. Alarm 25 - Alarm recording is increased to 25PPS while normal recording is reduced to 25PPS
  • Pre-alarm recording of up to 180 seconds, extendable to 30 minutes by adding extra storage in the bays provided.
  • Alarm recordings are stored in a partitioned area of the HDD and are not erased automatically as the drive capacity is used. The partitioned area can be set between 10% and 90% of the total HDD capacity.

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

Other easy to use features

  • Auto set-up - Auto detection of connected cameras with pre-assigned recording intervals and picture grades.
  • Copy and archive - Recorded images can be exported via SCSI into an external CD-R/RW, DVD-RAM, DDS2/3, HDD or ZIP drive. A CD Writer drive is now included as standard with every system.
  • Password lock - Three levels of password protection are present to limit access to settings and controls.
  • CompactFlash™ slot - In addition to image storage, all of the recording settings can be stored for easy transfer to another DX-TL2500E.
