Discussion of four options for cooling electronic/electrical equipment housed in enclosures and transit cases. These options include thermoelectric air conditioners, compressor-based AC, vortex coolers and air-to-air heat exchangers. Each cooling method is explained and the advantages of thermoelectric air conditioners are examined as compared to the other cooling methods.

The Armed Forces Service Center in Minnesota provides
members of the United States Armed Forces who are traveling
through the Twin Cities area with a free place to rest and
relax. It includes a lounge, kitchen, sleeping rooms, big-screen
televisions and free Wi-Fi. Since it operates as a non-profit
organization, the center is staffed mostly by volunteers 24
hours a day, seven days a week. Opened in 1970, this travel
oasis for military personnel has served more than 800,000
servicemen and women.

Property managers and facility engineers are very aware of 3-5 year paybacks commonly associated with 3M Sun Control Window Films, but how many of these same individuals are aware that window films can also be used to enhance the safety and security of their existing glass? The answer...over a million property managers and facility engineers.

As CEO of ISI Security, one of my jobs is keeping up with current security trends surrounding different industries and there is almost no other industry in which security impacts more people than the nation’s food supply. For the purposes of this discussion, food includes all commercially produced consumables.

Power over Ethernet (PoE) system efficiency is impacted across the entire length of the power chain, from power conversion at the output of the PoE power sourcing equipment (PSE), through power delivery to the powered device (PD), and on through conversion back to the various required voltages. To improve PoE system efficiency, power losses must be minimized across the entire length of the power chain, including the power supply, the power sourcing equipment and PDs (including their underlying PoE integrated circuits), and the channel (including cable, patch panel and connectors).
Wireless device proliferation in the enterprise sector has accelerated thanks to key trends including the Bring Your Own Device (BYOD) mobility deployment phenomenon. This, coupled with migration to new gigabit and multi-gigabit Wi-Fi standards such as IEEE 802.11n and IEEE 802.11ac, is increasing the challenges associated with powering a rapidly growing array of WLAN access points with various reach and performance capabilities. The solution is to take advantage of higher power delivery of the IEEE 802.3at Power over Ethernet (PoE) standard where needed, and use midspan technology to enable more flexible WLAN AP positioning while enhancing infrastructure scalability and delivering important networkwide power management capabilities.
There are two ways to deploy the latest high-power PoE technology: by upgrading the network switch, or by installing midspans in the existing networking infrastructure. PoE-capable switches offer the advantage of an integrated solution that requires only one cable for the network connection. However, this isn’t necessarily the best choice.

IP video is more affordable than ever and is really the best choice for entry into the video surveillance market or when considering a system upgrade.
Many facilities throughout the world have fire alarm, burglar alarm and surveillance systems that were installed before the coming of the Internet Age. For many, there is not the financial ability to replace these systems with more up to date equipment nor may there be pressing need as they properly perform their intended purpose. That does not mean that they can not be 'connected' and ‘IP enabled’ for a very reasonable cost.
