Taking the trouble out of transmission
NVT´s transmission solutions offer retailers an alternative to coax or fibre bundle cabling allowing them to expand their CCTV network as and when they need to. The solution has been implemented in several malls including the City Mall in Jordan
Specified throughout a variety of retail applications across the globe, NVT´s UTP CCTV hybrid video technology provides the cornerstone for the transmission of high-quality images up to one mile (1.6km), ie from the camera to equipment/control room.
Offering retail managers an alternative route to specifying a highperformance CCTV video transmission solution, versus the use of either fibre-optic or coax cable based media, due to the flexible nature of UTP (Cat5 or better) cable, it is also simple and quick to install. This intrinsic characteristic helps to minimise engineering time on site and disruption to retail business – all with the associated cost saving and project management benefits.
Flexibility of installation
A UTP multi-pair cable is much smaller in diameter than the equivalent coax or fibre bundle, so cable containment and space management within a retail environment is very much simplified using NVT video transmission. With its smaller size, additional/spare UTP pairs can be included in the Cat5 cable infrastructure, affording the provision of easy, low-cost expansion of CCTV camera networks should additional cameras be required in the future – and all without the requirement for any supplementary cable containment. Ideal for the retail environment, additional cameras needed to cover extended retail areas can be included in the CCTV network quickly and easily. Due to the constantly changing nature of retail floor space (where new or adjusted retail displays may obstruct a cameras view), NVT UTP transmission also affords the relocation of cameras with minimal effort, cost, and once again, disruption to daily business activity.
The limited physical cable flexibility of coax and fibre can be overcome with the use of NVT UTP transmission, thanks to the smaller diameter and much tighter bend radius of Cat5 cable – allowing it to be contained in less obtrusive ducting; connecting every camera without impacting on the interior architecture of a retail outlet, be it classic or modern.
Due to the multi-application nature of Cat5 structured cabling
(ie where it is used for telephone networks, data transfer etc), many
modern large multi-outlet retail sites are already equipped with a
comprehensive cable infrastructure, including ´spare´ UTP pairs which
can be cost-effectively utilised for CCTV camera image transmission.
Cat5 cable networks can also be specified at the planning stage of new-build facilities, with site contractors installing a dedicated UTP backbone as part of the construction schedule – ready for the connection of NVT products and the transmission of high-quality CCTV images.
Thanks to the built-in interference immunity of NVT video transmission products, NVT UTP cable networks can be included in cable containment alongside other services, permitting economical system design, allied to interference free operation – even when installed adjacent to high-voltage services, such as lifts or electrical power infrastructure. This intrinsic quality provides the reassurance of the delivery of consistently high-quality CCTV camera images – even if the video cable transmission route falls within a harsh electrical environment.
Power, video & data
Saving further on installation time, equipment, and associated costs,
NVT Power, Video & Data (PVD) technology can be used to supply
individual cameras with low-voltage power, via the same UTP cable
network. Obviating the need for additional fused spurs to be installed at
each camera point, this technology means electrical contractors are not
required to be involved in the installation of the camera network, with
the benefit of saving time and money in the provision of camera power.
Maximising the surveillance scene content for each camera is
essential in the provision of an economical and high- performance CCTV system for any retail outlet, from single-site boutiques with small camera counts, to large multi-site chains with networks consisting of hundreds of cameras. NVT UTP video transmission enables the ideal location for each camera to be realised; free from the constraints of installing cumbersome coax, or minimal radius (and expensive) fibreoptic cables.

Hybrid video solutions
NVT technology can be integrated to provide the best of both analogue CCTV and digital solutions. Using NVT Hybrid Video permits the use of more cost-effective analogue cameras, rather than more expensive and comparatively poor performing IP alternatives. High-quality NVT analogue camera signals can be distributed to an on-site digital video recorder (DVR), affording the best possible quality of recorded image for investigative/evidential purposes. However, if required, both live and recorded camera footage can be encoded (via the DVR or separate encoders), and distributed for ´remote site´ live monitoring and review via IP LAN/WAN. This hybrid solution is deal for multi-site retail chains with an in-house remote central control room, or if CCTV monitoring is required to be transferred during non-business hours to an ´off-site´ remote video monitoring station.
Recording analogue images on-site not only provides superior
image quality, it also enables the practice of ´on request´ footage to
be distributed to multiple locations via IP transmission, placing only
minimal demands on IP network bandwidths.
In addition to integration to IP, when considering the use of fibreoptic cable for the transmission of camera video, it is important to consider that this cable media requires highly specialised skills / professionals to install it; which adds substantially to the overall installation costs.
Using NVT Hybrid Video permits the use of more cost-effective analogue cameras
NVT Hybrid Video technology can provide a highly effective solution versus the use of fibre-optic cable, when being used to distribute camera video for distances up to 1 mile (1.6Km) – a distance particularly beneficial when retail CCTV networks are extended to cover outlying customer-parking facilities. This practical UTP based solution not only delivers the same ´fibre like´ video quality, but also delivers it at a fraction of the cost. Systems utilising NVT UTP to transmit camera video for ´the first mile´ over UTP, integrating to fibre at a central node for onward transmission, are proven to dramatically reduce total system costs – whilst maintaining the high-quality of the transmitted camera video.
Electronic surveillance systems are employed throughout the retail environment to protect customers, staff, stock and infrastructure, as well as enforce site-wide health and safety procedures and ensure corporate public liability obligations. Many CCTV installations feature cameras covering all internal and external public areas, in addition to delivery, back shop, staff-only areas, ATMs and cash-in-transit routes.
NVT UTP CCTV video transmission products are yielding significant savings, superior image quality and consistency of interference free camera video in retail surveillance systems worldwide, including the new Eden shopping complex in the UK, Jordan´s premier 160,000sqm one-stop family shopping & entertainment destination City Mall, and multiple high-end fashion house outlets across Europe.
