What is the Best Intercom?

Intercom History

History of Apartment IntercomsThe first intercoms were developed in the late 1800s. They used speaking tubes to talk to other people in the building.

How to Upgrade Your Access Control System

Upgrade Your Door Access Control System

Door Access Control DiagramThe classic door access control systems have been around for many years. These access control systems include one or more central control panels that connect to all the door readers.

Usually, the door readers use a Wiegand connection for communication. The reader-to-controller cable includes the serial Wiegand wires, power, and electric lock control. It also can contain several door control signals such as Request to Exit and door contact sensors. These older systems don’t have the latest features provided by the new access control systems.

Your old controller can be replaced so you can get the latest features and functions available from the new access control system. The new systems connect to the network allowing them to be integrated with other security systems. They provide many new capabilities that will improve your safety and security.

Panic Button and Other Security Systems for Schools

Active Shooter Emergencies

Safety and Security in SchoolsActive shooter situations have become a significant security issue. Many articles have been written about this. Solutions range from increased technology, active shooter drills in schools, and of course, gun control.  Ann Hampton Callaway even wrote a song, Thoughts and Prayers.

The article suggested that it was much better to provide threat assessment as a proactive approach to safety in schools. The objective would be to “identify students who are doing concerning behavior or may be in distress and getting them the help they need before they even resort to violence as an option.”

As a technology company, all we can do is suggest technology that can be used to prevent, control, and manage active shooter situations.

PoE for Network-Attached Devices

Door Access Control, IP Camera Systems, IP PA Systems use PoE

 

Network-Attached Devices IllustrationPower over Ethernet (PoE) is the easiest way to provide power to many network-attached devices such as IP cameras, door access control systems, and IP paging and Intercom systems. The network cable transfers both data and power to the device, making installation very simple.  The network cable includes up to eight wires. The data uses one set of wires, while the power uses another set of wires in the network cable.

This article describes how access control systems, IP Camera Systems, and IP paging systems utilize power over Ethernet (PoE)

It is not clear where the concept of Murphy’s Law originated. Some say that the original Murphy’s Law was “If there are two or more ways to do something, and one of those ways can result in a catastrophe, then someone will do it.”

The story goes that in 1947, Murphy was involved in a rocket-sled experiment in which all 16 accelerator instruments were installed in the wrong way, resulting in Murphy’s observation.

Murphy’s Law is sometimes expressed as “Anything that can go wrong, will — at the worst possible moment.”
