In this Product Spotlight we feature our Security and CCTV Systems (Video over Fibre) products in a market that is rapidly changing.

Security and CCTV Systems

Security networks are evolving - both in terms of how surveillance data is captured and how it’s transported. In a CCTV system, connectivity, or transmission, doesn’t exactly grab the limelight. Interest is focussed on the cameras, the control room, system storage, recording capability and, increasingly, on video analytics. Then come capital outlay and ongoing maintenance – just about everything apart from the transmission.

Many customers consider the system interface to be used and this has evolved from Analogue, an older technology, based on an analogue composite video signal, it's simple, straightforward and low cost. IP, the current technology, which can provide a one-to-one or one-to-many system. It’s often regarded as complicated, but provides greater flexibility, and allows different systems to be integrated onto a common platform. IP systems undoubtedly bring greater flexibility however, with that flexibility, comes a whole new set of challenges as systems become more complex. At Lanode we offer a range of IP Surveillance cameras. Finally there's the emerging technology of High Definition Video. Many camera manufacturers now offer uncompressed digital video outputs on their units. This High Definition video should not be confused with HD-IP interfaces, which offer a compressed HD signal in an IP format.

For transmission there are various options, which can be combined, including copper, fibre, wireless, cloud (WAN/3G), Microwave and Free Space Optics. Please see our 'viewpoint' article for a greater insight.

At Lanode we have expanded our relationship with KBC Networks and whilst their products are also designed for industrial control, site management and intelligent transport systems, the prime focus is on security and CCTV systems. The range is industrially rated, with wide operating temperature ranges and hardened casings; covers IP, analogue and high definition, and spans copper, fibre, wireless and WAN. All the products use the most advanced digital technologies to provide excellent repeatable performance for today’s CCTV systems, and include the following:

  • The FDVA series which supports transmission of one analog composite video channel over one multimode or singlemode optical fibre. Products with one, two or four individual modules within a single unit are available, offering substantial savings in racking and power requirements on site.
  • The FDVA-IA1 series which supports transmission of one analog composite video channel and one simplex (same direction as video signal) contact closure signal over one multimode or singlemode optical fibre.
  • The FDVA-DC1 series with one channel video with return simplex data, Point-to-Point Transmission.
  • The FCHA1 series which supports transmission of one video channel, one ‘Up the Coax’ data channel and two duplex contact closure channels over one multimode or singlemode optical fibre.
  • The FCHA1-DB1 series, supporting transmission of one analog composite video channel and one bi-directional RS422 data channel or Pelco Coaxitron “Up the Coax” telemetry over one multimode or singlemode optical fibre.
  • The FDVA-DB1 series to support transmission of one analog composite video channel and one bi-directional data channel over one multimode or singlemode optical fibre.
  • The FDVA-DB1-IB1 series which supports transmission of one analog composite video channel, with one bi-directional data channel and one bi-directional contact closure signal over one multimode or singlemode optical fibre.

There are also four channel and eight channel options available:

  • The FDVA4 series which supports transmission of four analog composite video channel over one multimode or singlemode optical fibre.
  • The FDVA4-DB1 series supporting transmission of four analog composite video channels and one bi-directional data channel over one multimode or singlemode optical fibre.
  • and the FDVA8 series which supports transmission of up to eight analog composite video channels over one multimode or Singlemode optical fibre.

 

Developed by KBC Networks, ThruLink is a hardware VPN (Virtual Private Network). It’s industrially rated and takes someone with even the most basic IP understanding just a few minutes to configure. It requires no ongoing maintenance and only requires a single port forward rule to be set up. ThruLink offers end-to-end encryption up to 256bit, ensuring security across the link. Once established, the system constantly monitors the link’s bandwidth and latency, making minute adjustments to its settings to optimise the channel. More details are available here.
