Silent Witness releases the DVMS Simplex series, an entry level line of digital video management systems (DVMS), to complement the premium DVMS Duplex series. The DVMS Simplex line is an intelligent, integrated multiplexer and digital recorder with 16, 8, 4 or 1 video input channels. The series is as easy to operate as a VCR, but it eliminates time-consuming tape management and maintenance costs. Based on a QNX real-time operating system, the DVMS Simplex is robust and stable providing mission critical reliability - in the event of a power loss. Secure, high-resolution digital recording and storage combined with an image authentication process to verify image integrity, ensures reliable, clear, transportable images. All Simplex models connect to point-of-sale (POS) systems allowing sales transaction details to be recorded with the video.
