D4 is an easy to use high-performance 4-channel DVR.
It has now been upgraded to provide a more complete range of features and functions, while retaining its simplicity of installation and use, with minimal configurable options.
Existing features such as 50/60PPS record performance and audio recording have been supplemented with serial telemetry and keyboard support, external storage expansion and retrospective searches for motion in the recorded video.
D4 can capture up to 50 pictures per second (50PPS PAL/60PPS NTSC), allowing real-time recording of an alarmed camera while simultaneously recording other cameras in time-lapse mode.
D4 is available with or without a built-in CD-R (D4 CD) for easy evidence archive creation. D4 is also available with Retail Solutions support (D4 RS) integrating the text from POS devices with images to protect against shrinkage at the checkout.
