DVR3-540

	We supply a version of the DVR specifically engineered for video professionals. Designed with mobility and ruggedness in mind, Stack's DVR3-540 delivers stunning picture quality even under the most extreme conditions.
The DVR3-540 captures video and audio that is equivalent or better than DV tape but is immune to the susceptibility of non solid-state devices to shock, vibration and temperature.

Unrivalled Recording Quality
	The DVR3-540 offers 10 selectable fixed bit-rates (1 to 20 Mbps) and Variable Bit-Rate (VBR) that can achieve bit-rates in excess of 30Mbps, even up to 50Mbps - dependant on image content. This matches the maximum bit-rate of Blu--Ray (in comparison, DVD's maximum bit-rate is 9.8Mbps).
The higher bit-rate not only gives sharper pictures and more vivid colours but is better capable of capturing fast-moving content such as sport without introducing compression artifacts. An option on the DVR3-540 is Intra-frame (I-frame) only record mode - a great benefit to video professionals using a non-linear editing system such as Avid or Final Cut Pro. To download and view footage recorded by the DVR3-500, please contact us: sales@stackltd.com.

Ruggedised Build Quality

	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.

Multiple Camera Input
The DVR2-5000M has an on-board ixer allowing up to 4 camera inputs. The DVR3-540 has an on-board 4 input video multiplexer to allow any format of 1 to 4 cameras (composite PAL or NTSC) to be recorded simultaneously with programmable scaling, crop and positioning of each picture.

Unlike less sophisticated products, Stack�s multiple camera input DVRs give the user full control over all screen elements.

Together with comprehensive recording set-up using the DVR Configuration Utility, standard across all models, the PC-based advanced Custom Display Utility provides full control of each picture�s size and position, together with picture cropping and overlay.

The system includes pre-set display modes - all editable. Camera identification shown on-screen is also fully configurable.

The easy-to-use software utilises a simple click and drag interface to set up how each input channel is displayed.

CAN-bus Interface
Stack DVRs support a number of external interfaces. The CAN interface allows a DVR3 to be directly connected to one or more Stack data expansion modules or a third party ECU. A GPS receiver can also be connected to the DVR to provide speed, position, altitude, time and date information.

Data Overlay Option
The GPS and G-force Data Overlay option enables data from these CAN and/or GPS sources, together with the internal 3-axis G-sensor and internal real time clock, to be overlaid on the recorded video image. Positioning the data on the image is simple, using the drag-and-drop PC configuration software supplied (above). A screen-shot from one of the camera inputs can be used as a background to further aid overlay composition.

The internal g sensor can also be used to automatically stop/start recordings.

User- configurable Record Modes
As well as the conventional record mode, the DVR3 range also provides a �continuous loop� record mode, whereby once the CF card becomes full, the DVR continues recording, overwriting the oldest recordings.

The DVR3 range also include an �Event Recording� mode, to enable specific externally triggered events to be recorded, with user selectable pre-trigger and post-trigger periods.

Configuration Utility
Stack's DVR configuration utility software gives the user full control of recording options including recording quality, screen aspect ratio, sound levels, recording triggers and CF card formatting.
