IP/PoE systems eliminate the need for local power, thus saving installation costs Cost considerations are an important reason to use existing installed cable as part of a new system infrastructure. Extenders in the form of media converters can help. For almost three decades, video surveillance systems existed in the form of analogue systems. Video coaxial cable was the primary method of transmission with a limited distance of about 750 feet. Analogue systems required separate...

When a manufacturer states a specific PoE power for a camera, always count on the maximum class power source Power over Ethernet (PoE) is an important consideration in IP video security infrastructures, and many people believe Institute of Electrical and Electronics Engineers (IEEE) standards are the last word. However, when it comes to PoE, there is a wide range of both voltages and wattages that can qualify as being within an individual IEEE power class. This applies to both...

By adding remote monitoring to service contracts, dealers and end users bothbenefit from substantial cost savings while reducing potential downtime Whether upgrading an existing surveillance and/or access system from analogue to IP, or installing a completely new system using structured cable, the ability to communicate, monitor and control IP devices delivers significant operational and economic benefits.

Ethernet switches are often overlooked andsometimes deemed a cheap connectivity pointwith little to no importance The Ethernet switch is a critical link between cameras, network video recorders (NVRs) and computers that need access to video feeds. The Ethernet switch not only provides the data connectivity but often the power to the IP cameras via Power over Ethernet (PoE). Ethernet switches are the fundamental backbone of a Local Area Network (LAN) and the critical connectivi...

The security industry’s continued migration to networked IP-based systems ensures that PoE will be integral in their design and installation Power over Ethernet (PoE) has without question become the de facto choice of security installers for delivering power to security and access control devices.

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...

The action of a voltage applied to a resistance element, draws power from the switch’s PoE port We often think about a power supply operating in a single format. A power source provides power to a device. You plug it into a wall outlet and that’s all that happens. PoE power is a far more complex. There is interaction between the source providing power and the device receiving power. This interaction is governed under the 802.3 AF and AT standards. These differences...

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...

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...

Significant technological advancements have created endless possibilities in how security is not only deployed, but also leveraged by the end user – the customer. For example, customers can now view surveillance at eight different offices in eight different states from a single, central location. A security director can manage an enterprise-wide access control system, including revoking or granting access control privileges, for 10,000 global employees from a company’s...

PoE has redefined how security professionals design and deploy systems The migration from analogue infrastructure to networked systems continues to gain traction at a rapid pace given all the inherent benefits networked technology provides for video surveillance and security applications.
