The ability to record in real-time the images from 64 x 2 Megapixel cameras may be impressive, but it is the features that make the Samsung Techwin’s SRN-4000 so highly resilient and easy to use that are likely to attract the attention of installers and system integrators who are looking to minimise the total cost of ownership of their clients’ video surveillance systems.
The SRN-4000 is able to simultaneously record and multi-stream the transmission of images at a high bandwidth speed of 400Mbps. It also offers the potential to record and store, via 12 internal hard drives, video captured by 64 x 2 Megapixel cameras for up to 108 days or up to 43 days for the same number of 5 Megapixel cameras. As well as the full range of Samsung Techwin IP network cameras, the SRN-4000 also supports other manufacturers’ cameras which are ONVIF compliant.
The 12 internal hot-swappable hard drives support RAID5 and RAID6 recording which provides protection against unrecoverable read errors as well as whole HDD failure. The SRN-400 also features an iSCSI interface giving users access to very large storage devices, if required.
A lot of thought has gone into the SRN-4000’s on-screen user interface to ensure that it can be configured in only four steps using the ‘Easy Setup’ wizard, whilst cameras can be registered without complication via a quick set up process. The provision of a local monitor output means that a separate PC is not needed to carry out any of these functions. A mouse and a monitor can simply be connected directly to the SRN-4000 and installers can then easily add and set up cameras.
“The SRN-4000 has a long list of features designed to ensure that it is highly reliable and resilient as well as easy to use and operate,” said Tim Biddulph, IP Product Manager for Samsung Techwin Europe Ltd. “Our design engineers have, for example, built in a hard drive ‘Hot Swap’ facility so that recording is not interrupted if a fault occurs, whilst power reliability is enhanced by way of a dual power supply. The SRN-4000 will continue to operate with a single power supply while the failed unit is replaced.”
Fast and efficient searching
The SRN-4000 enables users to quickly find and review video of any incident by using a combination of advanced motion detection as well as video analytics and metadata search options. Images can be searched by classification, e.g. keyword search such as ‘car’ or ‘people’, whilst a heat map feature provides the opportunity to statistically analyse concentrated spots of activity.
