Networking basics for security professionals: How does PoE work?

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...

Networking basics for security professionals: Transmission limitations

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...

Networking Basics for Security Professionals: Network switches face PoE challenges related to IP video

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...

Improving security system installations with Acceptance Testing

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...

Ethernet adapters ease the migration to networked platform

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. However, there are costs involved and they can be significant, especially if the move to networked infrastructure requires the removal of existing wiring and the installation of new Ethernet...

Power supplies: critical component of security solution effectiveness

Security integrators prefer to standardizetheir choices of system components such as power supplies using security manufacturers they are familiar with Power supplies may be inconspicuous and literally out-of-sight; however, they play a critical role in the effective functioning of security solutions.  Selecting and using the right power supply is an important aspect of ensuring that the installed security system delivers the desired outcome and of course, a good ROI. In...

Choosing the right power supplies for security installations

 Selecting the optimum power supply for a system is critical to an installation  When it comes to selecting power supplies, knowledge is power. Determining the power requirements of every systems product, taking into account their integration with one another is critical to ensure that you are selecting and installing the power solutions most appropriate for your installation. Such information will enable you to select the power supplies that will be required to keep your security sys...

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...
