• For increasing the storage capacity of the DAS-300
• External storage system for connection of a DAS-300 Basic Housing
  or a DAS-300 E for cascading
• Max. of 12 hard disks can be used (250 GB, 500 GB, 750 GB)

The newly developed DAS 4 Eco offers cost-effective storage expansion for the DMS 80/160 and 240 in keeping with the overall concept. The housing of the device, which is only one U high, can contain max. 4 SATA hard disks in lockable slide-in units with a maximum total capacity of 2 TB.

The hard disks can be replaced from the front of the recorder and in case of a hard disk failure the „EasyChange“ function ensures greatest ease of maintenance. Two redundant high performance fans guarantee optimal ventilation of the storage unit. Power is supplied directly via the 12V output of the DMS 80/160/240 - an additional power supply unit is therefore not necessary.
