Brownout Protection option provides up to 2 sconds of brownout protection (deependent on camera load). Extends recording after power loss by up to 1 second.
Designed with mobility and ruggedness in mind, Stack's DVRs for video professionals deliver stunning picture quality even under the most extreme conditions. The DVR2-500 & DVR2-500M capture 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 DVR2-500 & DVR2-500M offer 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 DVR2-500 & DVR2-500M 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.
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 Option The DVR2-500M has all the features of the DVR2-500 with the addition of 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.
Configuation Utility Stack's DVR configuation utility software gives the user full control of recording options including recording quality, screen aspect ratio, sound levels, record triggers and CF card formatting.
Each Stack DVR comes complete with harnesses, including camera and microphone 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. A comprehensive user guide is also included.
Cameras & Microphones We can supply both bullet / lipstick cameras (CCD) and amplified microphones which provide the highest quality video and audio signals to match the high quality recording of Stack’s Digital Video Recorder range.
Compact Flash (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.
GPS & G-force Data Overlay Option The GPS and G-force Data Overlay option can be added to your DVR. Simply plug in the optional GPS receiver and speed, position, altitude, time and date information can be overlaid on the recorded video image, along with the lateral-, long- and vertical-g data from the internal 3-axis accelerometer. Positioning the data on the image is simple, using the drag-and-drop PC configuration software.
Firmware Upgrades At Stack we are constantly working hard to improve the performance and capabilities of our products. Keep your DVR system up to date by downloading the latest firmware.
