A recently introduced updated version of Samsung Techwin’s SmartViewer central management software is able to support the company’s IP video surveillance devices, as well as its analogue devices, allowing previous investments in hardware to be safeguarded. V4.0 of the software is designed for video surveillance systems with up to 36 cameras and enables any authorised user with access to the Internet to view live footage or search for recorded video captured by connected cameras. Users can choose to simultaneously display images from up to 16 cameras in various split-screen modes and can save configuration details for future use. A key feature is a device manager which automatically scans for connected IP devices and enables the importing/exporting of settings. It also facilitates the remote updating of firmware and can therefore save time and money by negating the need for site visits. Other features include drag and drop video stream selection, varied codec support and real-time event listings.
