Solid-State Video Solution For high quality video recordings on the move, Stack’s miniature Solid-State Digital Video Recorders (DVRs) provide the optimum solution and are engineered specifically for harsh mobile environments.
DVR2 digital video recorders from Stack employ broadcast standard MPEG-2 video compression to record high quality 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. Recordings can be archived direct to DVD for playback on either a PC or a DVD player. A data overlay feature is also provided so that date and time may be stamped onto the recorded video. Additional parameters can also be displayed with an optional Stack Video Overlay module.
Stack DVRs feature a rugged machined aluminium housing specifically designed and manufactured to protect the unit in harsh and extreme environments. The unit is compact and durable with no moving parts (other than the sealed CF card access door), and is capable of operating where normal VCRs or DV recorders are not. Recording in harsh environments, such as continual shock and vibration, and extreme climate conditions is now entirely possible, making it ideal for all demanding recording applications. Its anti-vibration and shock-resistant abilities are perfect for consideration as commercial off the shelf (COTS) equipment. Stack DVR's have been successfully used in many demanding applications such as land-based military vehicles, aerospace, marine and many more.
The new Stack range of DVRs has a model to suit your needs: choose from variants offering up to 4 camera inputs, higher bit-rate options for broadcast quality recordings, models offering completely sealed units to IP67, extended operating temperature ranges, and extended recordings capacity.
Stack DVRs provide superior high-quality video recording in real time over a wide range of bit rates suitable for different applications - up to 15 Mbps is available, quality equivalent or better than DV tape.
Stack’s DVR2-200M & DVR2-400M incorporate an integrated 4 input video multiplexer to allow any format of up to 4 cameras (composite PAL or NTSC) to be recorded simultaneously on one screen with fully programmable scaling, crop and positioning.
Stack’s DVR2-100 is the perfect solution for applications that require reliability and toughness. In common with all of the DVR2 range, the DVR2-100 offers high-performance coupled with outstanding reliability.
All models in the Stack DVR range use MPEG-2, ideal for distribution or archiving on DVD discs and the format of choice for professional broadcasters. Up to 9 hours of DVD-quality video can be recorded on a single 16GB CF card.
Each Stack DVR comes complete with harnesses, including camera and mic power outputs, record control switch and status lamp. The externally visible bi-colour LED status lamp indicates record status, CF card “free memory” status and common error conditions.
Stack’s DVR2-200 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.
Like all DVR2 models, the small and compact design saves space and weight in remote and difficult installations.
The five user selectable bit rates, from 4 to 10 MBps, give flexibility in choosing the recording profile that best suits the application including broadcast-quality recording.
For the most demanding applications, the DVR2-400 can be used in harsh environments including high vibration and extreme temperatures.
The DVR2-400 has a IP67 standard waterproof rating and utilises Mil-type connectors.
The 32GB maximum card size allows longer continuous recording runs whilst the 15 Mbps maximum fixed bit rate produces unmatched video quality. Variable Bit Rate (VBR) gives optimum recording time whilst conserving memory.

The externally visible bi-colour LED status lamp indicates record status, CF card “free memory” status and common error conditions. A comprehensive user guide is also included.
Video Kit We can also supply the DVR with a video kit incorporating a bullet / lipsick camera (CCD) high-resolution and amplified microphone kit providing the highest quality video and audio signals, to match the recording high quality of Stack’s Digital Video Recorder range.
CF Cards We are happy to supply Harsh Environment Compact Flash (CF) cards in various memory sizes and industrial or commercial grades. Please contact your dealer/ distributor for details.
Data Overlay The DVR2-400/DVR2-400M have built-in date and time overlay stamp capability but by adding a Stack Data Overlay module a range of real-time performance data can be overlaid on the recorded video picture.
User-configurable alarm conditions ensure that all instances of where such conditions are exceeded, such as low pressures or high temperatures, etc., are quickly and reliably found.
Synchronized Video Logging The Stack Synchronized Video-Logger System enables up to 256 channels of data from any point on a vehicle or craft to be recorded synchronously with video from as many as 4 cameras and 2 channels of audio.
The system uses a unique approach to enable data from our Display and Data-Logging Systems to be continuously synchronized with video and audio recorded using a standard camcorder or video recorder. For high vibration and restricted space applications, Stack's range of harsh environment DVRs - as shown on this webpage - are the perfect video and audio source.
