Powering network IP video surveillance systems with fibre optic transmission

Fibre optic transmission has played a crucial role in the rise of IP video surveillance The advances in video surveillance technology have seen the increased adoption of network IP products over analogue systems. A key constant to this shift has been the critical need for reliable transmission of video signal. As the transition to network IP video continues, the need for the widely used coaxial cable is wavering in favour of Cat-5/ UTP cable and high-speed Ethernet connections...

True open platform IP video: the distinguishing characteristics

  Acquiring a true open platform surveillance software requires an informed decision Research reports pertaining to the IP video surveillance market repeatedly talk up the trend of "Open Platform". Keeping with that trend, it seems that every manufacturer is claiming its offerings to be IP-based and Open Platform. In the security industry these days, it has become almost embarrassing for a company to admit having a proprietary (single vendor) solution - there seems to be a...

Improving airport security effectiveness - key solutions

 Dealing with rising airport security threats  demand more innovative solutions   With the rise in large security threats since the commencement of this century, security of airports has become paramount. Looking into this issue Ashley Smith, BSIA (British Security industry Association) Civil Aviation Security Section Chairman, explains how a mix of properly interfaced security systems working in conjunction with monitoring and response staff offers a cost...

Motion estimation in H.264 video compression

Image quality of objects in motion is greater with H.264 technology In the first part of this three part series, the authors described the H.264 video compression standard including its history. In part two, the authors discuss motion estimation, the phase during which H.264 really distinguishes itself from other MPEG standards. Differentiating from other MPEG standards: Adapting raster block sizes for more detailed images H.264 distinguishes itself from the other MPEG s...

H.264 video compression standard for video compression: Improvement or buzzword?

 H.264 has become the compression standard of choice in the security industry The rising popularity of the H.264 video compression standard has established H.264 as ‘the buzzword' within the video surveillance industry. With all this talk of the possible enhancements brought to the fore by H.264, Kate Huber, Peter de konik and Piet Nieuwets of Optelecom-NKF present the true benefits and shortcomings of this popular standard in the first of a three-part review.H.264...

Wireless video surveillance: Opening the door to the endless possibilities

  Bridging the gaps in wired infrastructure with wireless broadband Today, public and urban business organisations have sophisticated geographically dispersed infrastructures, which require centralised supervision and the deployment of global security and surveillance networks. As the necessity for public and personal safety increases, the market and demand for multisite surveillance solutions with rigorous, video-based security standards is growing. One of the most recent...

Designing IP CCTV systems

  Going back to the blueprint - assessing the challenges of designing an IP CCTV The world of IP CCTV design is continuously progressing. Security system designers and installers have to frequently evaluate customers' needs when running an IP-surveillance system on a company's network. It is up to the CCTV sales manager to eradicate any concerns regarding IP-based CCTV systems and look at the requirements of each customer, subsequently offering bespoke networks to suit the...

Estimating bandwidth requirements for modern surveillance systems

  Bandwidth is an important consideration for CCTV systems to reach their full potential Most surveillance systems today transmit data over IP networks. As manufacturers continue to improve the capabilities of CCTV systems, the amount of traffic travelling on a network becomes increasingly large. Bandwidth is a key consideration in managing surveillance systems and ensuring their full potential is reached. In this article, Bosch discusses the importance of bandwidth and ho...

Extending Ethernet capabilities to enable better network security applications

PoE technology allows for safer environments through better security systems Power over Ethernet is both convenient and affordable, says Jonas Rehnberg of ASSA ABLOY Future Labs. The benefits to network security are immense, be it in powering security cameras with added features or enabling better access control systems and intruder deterrents. Hailed as a watershed innovation when first standardized in 2003, Power over Ethernet (PoE) offers a way of supplying electricity to n...

Interoperability of building security systems: Protocols and standards

   XML, API and web server offer the ability for interoperability between proprietary software Today's facility executive wants to purchase systems and components from various manufacturers and have those components work together as one system. They want "open systems" that allow the manufacturers to offer new features and add value without locking the owner into a single vendor's proprietary protocols. In short, they want Interoperability.Hirsch Electronics...
