“We are committed to the ‘Safewards’ initiative’, a key aim of which is to reduce the rates of conflict in in-patient mental health settings,” said Mark Milliard, Capital Projects Manager at Norfolk and Suffolk NHS Foundation Trust. “We believe that the use of smart technology, such as IP network based video monitoring systems, can play a large role in helping us achieve this objective.”

Mark, who has worked within NHS Estates since 1986, has over recent years overseen the migration of the Trust’s analogue CCTV systems to video over IP solutions. “The analogue systems that were installed a number of years ago became increasingly unreliable and we made the decision to upgrade them with IP network based systems,” explained Mark. “A key advantage of being able to transmit images over the network is that it provides the flexibility for any authorised user to view live or recorded video captured by any of the cameras from their PCs. We realised that this would provide us with much more flexibility in terms of how we monitor activity at the mental health units, compared to the analogue CCTV systems which could only transmit captured images to a central location.”

In compliance with the Trust’s obligation to achieve best value from its investment in new technology, Mark initiated a tender process and invited a number of installation companies to submit proposals to install and service video monitoring systems at each of the 19 locations. The tender document specified which cameras should be installed.  “It made sense to source the cameras from just one manufacturer and from an ongoing maintenance point of view, to deploy the minimum possible number of different camera models,” said Mark. “I decided, therefore, to carry out my own research as to which manufacturer had a product portfolio which could best cover all our requirements, as well as offering us the value we were looking for. Part of the value formulae had to include a rock solid reputation for reliability, as well as cameras with advanced technical features which would allow us to capture and monitor high definition images, regardless of the location or environmental conditions.”

Mark’s extensive evaluation of a large number of manufacturers resulted in a shortlist of two, from which Samsung Techwin emerged as the winner.  “I was particularly impressed with the quality of the images which could be captured by the Samsung Techwin cameras and the fact that each camera, depending on its location, could be configured to multi-stream images at different frame rates and at different resolutions. This offers a significant benefit from a network bandwidth management point of view.”

Mark established that only three Samsung Techwin cameras would need to be specified to provide the coverage required and all three models are part of the Samsung Techwin WisenetIII camera range including the SNV-6084R vandal-resistant 2MP full HD network dome camera, the SNO-6084R weather resistant bullet camera with a motorised varifocal lens and built-in IR (infrared) illuminators, and finally, the SNV-6012 2MP full HD vandal-resistant flat dome camera.

The images from all of the cameras are recorded onto Samsung Techwin SRN-1670D NVRs. These have been designed to have the look and familiarity of a DVR, whilst delivering all the benefits of a network video recorder. Unlike most NVRs, which can only be programmed remotely, the SRN-1670D can be locally controlled with the help of a mouse and a very easy to use on-screen display. The SRN-1670D has the capacity for five SATA HDDs, offering the potential for a massive 10Tb of on-board storage. It can record audio across all channels and has a built-in DVD writer and USB ports for easy export of video evidence.
