Grundig has launched its new 16 channel EX-SDI (Extended Serial Digital Interface) hybrid DVR, the GRX-K4416A. The DVR records EX-SDI on all channels, but has the flexibility to record HD-SDI, 960H analogue and 760H analogue video streams simultaneously. CCTV systems using the DVR can include a combination of all coaxial-based video technologies, so existing and previously installed cameras can be re-used. The DVR will automatically configure each channel to suit individual camera video stream technologies.
EX-SDI technology, like HD-SDI, enables the transmission of HD digital video, in real time, over coaxial cable. Whereas HD-SDI has a 100m transmission limitation using RG59 coaxial cable, EX-SDI will transmit 330m. This extends to 670m if the higher quality RG11 cable is used. Image quality is better than IP in live and similar to that of IP record mode. The DVR uses the simple, point-to-point installation method of analogue.
The new Grundig DVR provides comprehensive functionality for CCTV applications of all sizes and complexities. Its can be controlled using Grundig Control Center software, allowing cost-effective, EX-SDI, HD-SDI or analogue camera systems.
Grundig’s Control Center software allows remote access to the DVRs for set up and configuration. It uses an Internet Explorer web browser for live viewing, playback, search, backup and remote configuration. Grundig’s GD Viewer app also allows convenient viewing by iPhone or Android smartphones.
EX-SDI enables installers to offer customers a cost-effective, digital upgrade to analogue systems, saving money by re-using the same coaxial cable infrastructure.
