For video recordings on the move, StackÕ_ miniature Solid-State Digital Video Recorders (DVRs) provide the optimum solution and are specifically designed for use in harsh environments. Stack recorders employ broadcast standard MPEG-2 video compression to record real-time video and audio direct to a Compact Flash (CF) card. The card can be removed with ease and played on a PC or laptop using a standard media player application.

The DVR2-440 incorporates a 4 input video multiplexer to allow any format of 1 to 4 cameras on one screen, with fully programmable scaling, crop and positioning. For the most demanding applications, the DVR2-400 can be used in harsh environments including high vibration and extreme temperatures and has a IP67 standard waterproof rating and utilises Mil-type connectors. StackÕ_ DVR2-440 offers professional performance even under the most difficult conditions including wet and / or high vibration environments. The unit is fully waterproof and boasts an extended operating temperature range of 0¡C to 70¡C.

The DVR2-440 offers 9 x recording bit rate (1 Mbps Min. 15 Mbps Max.) 9-140 Mins/Gbyte, Up to 18 hours of DVD quality (Composite) video can be recorded on a single 32GB CF card.

As well as the conventional record mode, the DVR2 range also provides a continuous loop record mode, whereby once the CF card becomes full, the DVR continues recording, overwriting the oldest recordings. The DVR2 range also include an Ò…vent RecordingÓ mode, to enable specific externally triggered events to be recorded, with user selectable pre-trigger and post-trigger periods.

Note
Stack recorders can be connected to a PC over USB and then put into card reader mode, so that MPEG2 files on the CF card can then be played back in a media player on the PC (whilst the CF card is still in the DVR).

The video listed above features the Stack STGPS GPS (NMEA-0183) interface and data overlay optional accessory.
