Two important trends will influence manufacturers’ introduction of next generation VoIP phones and streaming video cameras: PoE (Power-Over-Ethernet), and Gigabit speeds. These newer technologies will allow lower cost and higher performance network devices. Media converters will also adapt. By incorporating these enabling technologies, media converters will allow networks, and the points at which we interface to them, to evolve.

As new devices are added to the edges of networks and beyond, companies will look for cost-saving installation methods. Power-over-Ethernet allows network-based devices to draw 48 VDC power from the same cable used to connect to the network. This low-voltage solution eliminates the need for costly electricians to run new high voltage AC circuits to remote device locations. By standardizing on PD (Powered Device) power conversion circuitry, device manufacturers can also reduce costs–and prices–for devices such as next generation VoIP phones and network cameras. continue »

In today’s environments a large number of companies are designing their networks with Power over Ethernet in mind. The reason for this is the implementation of Voice over IP networks, IP security cameras and wireless connectivity.

What is Power over Ethernet (PoE) technology?
PoE is a technology for one of the most widely installed networks in use today, the wired Ethernet network. PoE allows the electrical power necessary for the operation of an end device to be carried by data cables along with the data rather than using a separate power cord for that end device.

In June of 2003 the IEEE committee ratified the standard for 802.3af, the means of providing up to 15.4watts of power over a Category 5 or better Ethernet cable. continue »

We’re back from another productive week in New York exhibiting at ISC East. The busy show once again highlighted the increased focus on security in both the home and business environment. From fire alarms over IP to video surveillance over IP, the hot topics were once again IP and intelligent digital surveillance solutions.

Highlighting these technologies were two inaugural displays at ISC East - SmartHome@ISC and The Security Operation Center (SOC). From the ISC East website, the SOC is….

“…a first-of-its-kind, real world solution, dedicated to demonstrating a live, best-of-breed, multi-vendor-converged Security Operations Center, that integrates physical security and enterprise IT products. With over 6,000 sq. ft. of show floor space, the Security Operations Center is the largest ever public demonstration of physical security and enterprise IT security convergence.”

Produced by IPVS Magazine, the 6,000 sq. ft. display was an impressive showcase of the power of IP video security. Along with our own booth, we exhibited in the SOC alongside such companies as Axis Communications, exacq Technologies, and Milestone Systems. IPVS did a great job of integrating the technologies of 20 vendors into one IP video network!

We’re proud to say our 24-port Power-over-Ethernet MILAN switches ran the network and powered the IP video cameras in use.
