IP video surveillance - Expert commentary
Successful video infrastructure management requires visibility into the network’s behaviour The importance of video in an organisation has been growing over the past several years, almost exponentially. In retail, video images can help detect or deter theft by employees and patrons. Casinos use video partly due to state regulations, to ensure gaming activity is free of deceit or fraud. Branch offices use video to communicate with the head office. Schools use video for di...
Large busy casinos must maintain continuous surveillance of multiple tables and machines High-definition (HD) cameras are a perfect fit for the casino market. HD security cameras provide six times the resolution of analogue cameras, supplying images with sharper edges that easily identify faces, cards, dice, chips, currency, and fill slips. In addition, high-definition IP cameras can reduce camera count. A single, 1080p camera can effectively cover poker, roulette or craps tab...
Video surveillance systems are extensively used in the casino market, but ironically casinos are more often than not behind the curve when it comes to installing newer security systems. Video technology adoption in the casino market has recently slowed down because of the economy. Analogue to IP migration The economic downturn slowed the analogue-to-IP transition process of video surveillance technology used in the gaming market, says Laurie Smock, vice president of sales,...

Just as with network switches, there are no real standards for midspans In general terms, a midspan is a power over Ethernet (PoE) power source that is placed between a network switch and the device being powered, hence the term midspan. The real question is, with almost all network switches providing PoE power, why do we need a midspan? The answer is, in some cases we don’t, but in others we do. As with any other product we have discussed, we need to first consider that...
Too often a valid assumption turns out to be the opposite in practical operation It’s easy to misinterpret product specifications of IP video transmission products to the detriment of system functionality. We have seen how this problem relates to port speed, power over Ethernet (PoE) and transmission media. Now let’s look at some additional aspects of product specifications – and how they can be misinterpreted. Importance Of Temperature Rating What about te...
Organisations must find more effective ways to optimise the use of the resources they have available As market demand intensifies for higher resolution from megapixel, and 4K cameras, customers will begin to feel the ensuing cost pressures caused by the increased need for greater processing power.

Since last year there has been a lot of talk with regard IP security cameras with 4K resolution. As with any advancement in video security, this too has come about due to advances in consumer electronics. While being the “latest and greatest,” it still raises questions as to actual, practical everyday usage. What Is 4K Resolution? Let’s start by defining 4K. Back in the day we had HDTV, which in some cases was defined in terms of its resolution of 1920 hor...
Differences between standard data applications and the requirements of networks designed for IP video security applications are critical for your system's performance When the need to purchase a network switch arises, many IT directors immediately turn to two favourites, HP or Cisco. They have become to the networking environment what IBM was to computers: “No one ever got fired for buying IBM.” Certainly, switches play a crucial role in enhancing your network by i...
Standards for camera manufacturers presented a new challenge with the introduction of security cameras that require more than 30 Watts of power Standards for camera manufacturers presented a new challenge with the introduction of security cameras that require more than 30 Watts of power. Many of these involve pan-tilt-zoom (PTZ) domes and heaters and blowers that require additional power. This development created two areas of confusion which is highlighted in this article by N...
Standards are like a warm blanket on a cold winter night. They make us feel safe and warm. A standard tells us the devices we use within our systems will interact with each other regardless of manufacturer. For IP-powered PoE devices, we depend on standards such as 802.3af for devices requiring up to 15.4 watts and 802.3at for devices powered up to 30 watts. We depend on the devices generating the power to be able to be read by devices receiving the power. Our dependence is not al...

Transmission of video and PoE power for IP security cameras over infrastructures can be confusing. Network infrastructures are designed using twisted pair cabling that we refer to as CAT (short for Category) cable, also referred to as UTP (Unshielded Twisted Pair). Security systems, coming from an analogue environment, have historically transmitted over coax cable, and with the use adaptors can transmit over CAT cabling, which can be further broken down into single pair twist...
Video analytics allow users to automate the use of video and extract more value Almost anyone in the video analytics market will admit that the capabilities of the technology were initially oversold. The first generation of analytics simply didn’t work as promised, and an undercurrent of distrust of the technology in general still haunts the market. Ironically, video analytics capabilities have now matured into a robust and dependable option for a variety of applications...

Video cameras are great tools for security at airports, but increasingly cameras are offering operational benefits, too. Anthony Incorvati, business development manager, critical infrastructure and transportation, Axis Communications, says cameras at airports today are often used for operations rather than (or in addition to) security. For example, cameras mounted at departure gates are not installed for security but rather for operations and maintenance, as a tool to help airlines...
Are network switches really designed for IP video security? The simple answer is no. As video security migrated to IP, a major concern for video security personal was the future of their positions in regard to system specification and control. After all, networks are networks, and they are under the control of IT directors. However, as transition occurred and the demands of IP video security grew, it became apparent that database networks don’t directly translate into IP vid...
