Coaxial control offers convenience as well as cost savings, allowing both video and telemetry control to be transmitted via conventional analogue coaxial cabling. As well as a reduction in cabling costs, there is also the opportunity for existing equipment to be upgraded quickly and easily.

The SRD-850DC and SRD-1650DC are eight and sixteen channel DVRs which can simultaneously record real-time CIF images across all channels and selectable channels up to 4CIF, whilst the SRD-870DC and the SRD-1670DC can simultaneously record real-time images across all channels at 4CIF.

The SRD series provides customers with the choice of four-, eight- and sixteen-channel DVRs which are available with or without built-in DVD drives. All twenty models feature Virtual Progressive Scan (VPS) which eliminates the problem of blurred edges on moving objects to provide picture-perfect still frames and selected models come complete with an HDMI output able to upscale images to 1080P.

Additional installer and operator friendly features include a fully removable back panel so that hard drives can be swapped and upgraded without having to unplug all the cables and a multiple language on screen display. Data from ATM, POS or access control devices can be captured with the text data saved along with associated images to be played back if required at a later date.

Dual codec operation delivers different streams for both high performance recording and optimised transmission, whilst a built-in web-server allows live and playback viewing options with the ability to back up incidents via a web browser. For advanced network operation, SRD series DVRs are all fully compatibility with Samsung's Centralised Management Software (CMS) which provides enhanced functionality as part of a complete integrated security system. They also share the same intuitive Graphical User Interface (GUI) menu structure to make it easy for operators, for example, to set up each channel to record at different frames rates or resolutions.
