A 300-plus camera city centre video surveillance scheme in Lincoln has been installed and commissioned using cameras, monitors and switching equipment from Dahua Technology. The previous analogue-based CCTV system was more than 20 years old and had become expensive to maintain, so City of Lincoln Council decided to replace the analogue cameras and transmission equipment with HD digital equipment. The total cost of ownership has been reduced by the savings made on legacy fibre lease costs, as well as reduced energy consumption and the ability to configure and maintain the cameras remotely. Installation of IP full HD system The installation of the new IP full HD system and network is part of Lincoln’s smart city strategy – Vision 2020 The design of the new all-wireless encrypted system was based around delivering flexible technology, reducing the total cost of ownership, ease of installation, lower maintenance requirements, smart edge analytics and remote connectivity. Environmentally friendly aspects of the project included specifying lower-energy equipment, integrating remote support and recycling hardware wherever possible. The council employed independent consultants Lever Technology Group to help them ensure they had a robust and future-proof radio network design. The installation of the new IP full HD system and network is part of Lincoln’s smart city strategy – Vision 2020 – which seeks to drive innovation in the city and harness new technologies to improve the lives of citizens. One of the results is the provision of free Wi-Fi in the city, working alongside the Dahua cameras using the same IP wireless network. Bandwidth efficiency using H.265 compression A combination of fixed and PTZ cameras were installed over a new 1GB duplex network. These include cameras from the Dahua Pro series, which features high image quality, bandwidth efficiency using H.265 compression and excellent low-light performance. Bullet cameras from the Ultra series – with powerful optical zoom, IR distances of up to 50 metres and software which supports people-counting and heat-mapping – were also installed. The design of the scheme incorporated both camera and server-side analytics with legacy motion and audio detection The bandwidth efficiency of the cameras meant that multiple cameras could be installed in any given position, providing 360° coverage of locations and up to 20 Megapixels of video capacity per location – compared with less than 400,000 pixels with the previous analogue cameras. The design of the scheme incorporated both camera and server-side analytics, including video content analytics, facial recognition, ANPR, heat maps and pedestrian counting, as well as legacy motion and audio detection. The objective of the facial recognition aspect is to support operators in areas such as the search for missing and vulnerable individuals. PoE switches for providing power The superior image quality of the new system is borne out in figures which show an increase in ‘actionable’ images from 5% with the previous system to 60% successful reviews with the new one. Dahua PoE switches were also installed to provide power to the cameras, which are then connected to a layer-2 network. A new video wall comprising ten Dahua DHL49-4K LED backlit 49-inch 4K Ultra HD video wall display units featuring industrial level wide-viewing LCD panels, was fitted into a newly refurbished control room in City Hall and connected to i-Comply wonderwall video display drivers. This is a great collaboration of key project partners that have a tried-and-tested pedigree and working relationship with Videcom Security" Supplied through authorised distributor Mayflex, the entire system was installed by public space CCTV specialists Videcom Security, which worked with other partners to provide a high-performance, efficient and feature-rich system. Cost-effective and reliable equipment Bill Mead, Managing Director at Videcom Security, said that working largely with Dahua video equipment meant it was easier for engineers in terms of configuration, as well as being cost-effective and representing good value for money. “Working with the Dahua product range has been great. The products have proved to be reliable and we experienced very few problems, from the initial configuration through to installation and commissioning. “This is a great collaboration of key project partners that have a tried-and-tested pedigree and working relationship with Videcom Security. We broke new ground with the development of 4K H.265 decoding, the support through Luxriot for camera-side analytics and edge recording, and the development by Dahua of camera-to-camera communication, allowing for non-connected systems to communicate locally.” Infinet 5GHz and Siklu E and V band radios Videcom Security is a certified Dahua Integration Partner, training for which was delivered both by Dahua and the Mayflex Academy Dahua is a solution provider in the global video surveillance industry and associated technology and has a keen focus on innovation by investing heavily in research and development. For the Lincoln city scheme, its products were selected based on their performance and cost-effectiveness to meet project budgets. Videcom Security is a certified Dahua Integration Partner, training for which was delivered both by Dahua and the Mayflex Academy. This helped Videcom negotiate key firmware enhancements, which added to many of the analytical features available in each of the cameras. The wireless network is built with Infinet 5GHz and Siklu E and V band radios. Resilience and diverse routing has been built into the network design, which supports video surveillance as well as public Wi-Fi and capacity for smart city services. Luxriot have worked closely with Dahua, supplying their Evo Global video management system and supporting edge analytics integration through their ‘events and actions’ management, which has also been integrated through to i-Comply’s VTAS CRVMS software (now rebranded as Viewscape). Real-time control and video streaming The Dahua system implemented by Videcom Security provides the main elements of our tier-1 solution" The introduction of H.265 compression was ground-breaking for such a project, with the system capable of displaying 4MP and 6MP H.265 to the operator’s spot monitor with real-time control and video streaming. “The Dahua system implemented by Videcom Security provides the main elements of our tier-1 solution,” said Martin Byrne, CCTV Team leader at Lincoln City Council. “The police are extremely pleased with the system and we’ve had very positive feedback from them. “There is really no comparison from how we operated previously to how we can now. It revolutionises how we manage the CCTV systems and data. The potential for what we can achieve going forward is remarkable. We have now started to get real results from the investment in analytics; in particular vehicle and people-counting has been deployed and data is used to enhance other city projects.” Martin added: “Dahua has taken time out to visit and discuss with us our ambitions for smart city services. We have adopted Dahua as our brand of choice for CCTV cameras and have so far been very pleased and impressed with their reliability, low-light performance and overall image quality.”
Siklu Inc., a global supplier of mmWave solutions, has announced that its wireless radios have been deployed in the City of Lincoln, United Kingdom. These systems provide 14 high capacity wireless data links in support of a modern IP networked CCTV system, primarily to provide surveillance for the city and public spaces. The new wireless network is part of the Vision 2020 project announced last year. Vision 2020 is a three-year plan to build a smart city improving the city’s infrastructure, roadways and parks, and includes investing in a new transportation hub. Previously, the cities CCTV system was transmitted back on traditional analogue fibre circuits, these were both costly and bandwidth limiting. To install the wireless network, the City of Lincoln Council worked closely with security systems integrator Videcom Security Ltd, a company specialising in large multisite Town and City Centre public safety CCTV systems. Videcom chose Siklu as their wireless partner following previous successes in Watford, London Borough Richmond, Ipswich and Cambridge City where Siklu hardware had already been successfully deployed, demonstrating the best cost and performance solution. Ultralow latency combined with high reliability and accurate forecasted uptime and resilience, added weight to the tendered design and installation mmWave EtherHaul E-band radios The project involved installing Siklu’s mmWave EtherHaul E-band radios to deliver 1 Gbps full duplex capacity for the main backhaul resilient ring over the 80 GHz frequency. Utilising Siklu’s Layer 2 switch functionality to deliver resiliency and diversity routing, the network provides ‘mission critical’ up-time with automatic fail-over. In addition, Videcom installed Siklu’s 60 GHz V-band frequency radios to connect 300 cameras at the street level including city wide Urban Traffic Cameras. Ultralow latency combined with high reliability and accurate forecasted uptime and resilience, added weight to the tendered design and installation. Significant cost savings on transmission and reduction in maintenance have also helped to reduce the total lifetime cost of the CCTV system. Videcom city-wide CCTV surveillance “At Videcom, we have always been impressed with the level of support and in particular, Siklu’s commitment to training of our engineers and the ongoing direct support offered,” said Bill Mead, Managing Director of Videcom Security. “We are pleased to work closely with Siklu and are looking forward to the next project.” The recent project with the City of Lincoln Council is part of our commitment to providing the most reliable, interference free mmWave technology"The extended CCTV camera coverage, including the creation of a Safe Zone, utilising Siklu radios connecting high specification Dahua cameras is already providing significant results, both proactively and reactively. Spare transmission bandwidth is allowing the planning of smart services to the City as well as Wi-Fi connectivity and car park data sharing. “We’re pleased to have had such a successful working relationship with Videcom Security on numerous projects throughout the United Kingdom,” said Eyal Assa, Siklu’s CEO. “The recent project with the City of Lincoln Council is part of our commitment to providing the most reliable, interference free mmWave technology available to the market for Smart City and surveillance system networks.”
Redvision provides a software development kit (SDK) to allow NVR and VMS manufacturers to integrate and control its new rugged Full HD RV30-1080 & 720 PTZ camera range. Comprehensive integration of all PTZ functionality The SDK is presented in exactly the format control system developers require for comprehensive integration of all PTZ functionality. Bill Mead, MD of Videcom Security Ltd, recently integrated the company’s VNR control system with Redvison’s HD IP PTZ camera, explains: "Redvision is a product partner of Videcom Security. The company provided us with a Firmware and SDK package based on the ONVIF integration protocol. This allowed us to integrate our VNR control system with the RV30-1080 rugged PTZ, for use in local authority applications, where we are widely used and specified. The integration of video cameras and control systems is key to the successful implementation of IP CCTV systems. To this end, Redvision provided their SDK in such a way that our developers could complete the integration within 24 hours. This turn-around is unheard of with most other camera manufacturers and testament to the clear and simple way the SDK is presented. Not only that, the integration is far more comprehensive than most. It includes variable speed PTZ operation, essential for applications with direct operator control, with almost no joy-stick latency. Wipers and IR lamps can be switched on and off and all pre-sets, night and day mode operation and tours are enabled through our VNR" Both the 1080p and 720p models of the Redvision HD camera series share the same SDK integration. The 1080p model, with IR and white light illumination switched on, is effective up to 120 and 100 metres respectively, with operators recognising people at up to 40 metres. By comparison, the 720p model is effective up to an impressive 200 metres, with operators identifying people at 70 metres. Video compression format options include H.264, MPEG4 or JPEG and both models have a 30x optical and 12x digital zoom.
Videcom installed Silvernet MAX 95 and MAX 500 links to achieve high speed IP transmission of video When North Lincolnshire Council commissioned town centre specialists, Videcom Security to install a new public safety CCTV camera system in Winterton, the specification called for the images captured by the cameras to be transmitted without loss, to its central control room 28 Kilometres away in Scunthorpe. Traditional transmission methods using leased fibre to transmit the cameras back to Scunthorpe was neither a practical option nor cost effective, so Videcom, recommended a secure wireless IP network solution manufactured by SilverNet. Winterton is a small town with a population of 4,700 people. North Lincolnshire Council decided to fund the installation of the video surveillance system in order to deter and detect anti-social and criminal activity and by doing so, demonstrate its support of the local community and businesses by creating a safe town centre environment. 24/7 monitoring of live video, as well as access to recorded images, was considered to be essential if the video surveillance system was to be effective and it made sense for this to happen at an existing, fully equipped central control room in Scunthorpe. “Having been responsible for maintaining the Scunthorpe town centre video surveillance system for the past eight years, we were very pleased to have been awarded the contract to provide the complete solution for this project,” said Bill Mead, Executive Director of Videcom Security. “We sourced full HD ONVIF LG fixed cameras and Redvision IP PTZ domes to provide coverage within Winterton Town Centre. Having very successfully worked with Silvernet on other projects, including Scunthorpe and Brigg, we had no hesitation in recommending the installation of MAX 95 and the new high capacity MAX 500 wireless transmission links, both of which are from the SilverNet PRO range, to achieve the objective of high speed IP transmission of video over the required 28 Kilometres.” Videcom Security has installed two new Silvernet MAX 500 links back-to-back, high up on the southern tower of the Humber Bridge, whilst seven pairs of MAX 95 links have been installed to collect the cameras locally at street level, producing a resilient solution with high capacity Backhaul transmission. “Installing the SilverNet links on the south tower of the Humber Bridge was an interesting challenge, but overall, with careful planning and safety induction, it proved to be an uncomplicated installation process,” said Danny Harsley, Senior Network Engineer for Videcom Security. “The key to success for any project which involves wireless network transmission is to carry out a detailed site survey and work with the manufacturer to calculate the bandwidth requirements. As a result of doing this, we have been able to supply the client with a solution which utilises transmission equipment that is stable and has a huge throughput capacity. “Silvernet are Videcom’s preferred IP Wireless Partner. They provide us with excellent pro-active pre-sales and installation support, as well as first class training.”
SilverNet's high capacity Backhaul links facilitate transmission of images captured by cameras located throughout the town centre The SilverNet Wireless network has been deployed as part of a project to upgrade the town centre’s video surveillance system which has also seen the opening of a new state-of-the-art CCTV and public safety control room installed in Watford Town Centre. This has been designed to help police respond quickly to any incidents, whilst also providing the opportunity to monitor traffic flow and the supply of live updates for the Highways Authority. Waltham Abbey based Videcom Security were awarded the contract to provide an IP Network based solution which would support the existing town centre cameras, whilst providing an easy upgrade path to ONVIF compliant Full HD cameras and control equipment that Watford Borough Council may wish to deploy in the future. “One of our top priorities as a council is making Watford town centre as safe as possible for residents and visitors, no matter where or when they visit,” said a spokesperson for Watford Borough. “The relocation of our control room within Watford Police Station means that we can provide a faster, more efficient and joined up service, and that is good news for all of us!” The SilverNet's high capacity Backhaul links which provide a full duplex resilient ring, the 240 Mbps trunk links and 95 Mbps uplinks were used to facilitate the transmission of the images captured by 60 high resolution cameras located throughout the town centre to a central control room where SilverNet’s SilverView Network monitoring software is working alongside a Synectics Synergy command & control solution and bespoke VNSoft remote monitoring software. By being able to take advantage of the latest advances in network wireless technology, Videcom Security were able to minimise installation time and costs by negating the need for the laying of new cabling and engineering work and also giving the local authority significant ongoing revenue savings associated with the existing Telco leased circuits which were previously used for CCTV video transmission. The SilverView network management software enables SilverNet wireless equipment and the installed video codecs or IP cameras to be collectively managed regardless of their physical location, via a PC. It features an ultra-easy to use on-screen dashboard which eliminates the complexity normally associated with the management of complex network systems. “SilverNet is our preferred technology partner for wireless network solutions and our decision to recommend its Wireless solution for this particular project has been more than justified" “Working closely with Mike Skett of Goodwill Associates, an independent security consultancy, we utilised the expertise of our engineering team across a number of disciplines including CCTV, Electrical and Project Management, in order to meet the client's expectations for this project,” said Bill Mead, Executive Director of Videcom Security. “Despite having a deadline of just twelve weeks and the challenge of working through one of the worst winters on record, we managed to complete the project on time and on budget.” “SilverNet is our preferred technology partner for wireless network solutions and our decision to recommend its Wireless solution for this particular project has been more than justified by the performance of the equipment which all worked ‘out of the box’ and has helped make this project a jewel in the Videcom portfolio. The equipment was delivered exactly when we needed it and we were impressed by the support provided by the SilverNet team at every stage including site survey assistance, factory pre-testing, training and technical advice during the installation and commissioning process.”
