The Evolution of the PTZ Camera

Pan, Tilt Zoom Cameras Provide Increased Capability

PTZ Cameras
PTZ Cameras

We have come a long way since the first pan, tilt, zoom (PTZ) cameras. The first PTZ cameras were relatively primitive. These early cameras shared the technology with television cameras and used vidicon vacuum tubes and other analog components to capture the video.

This article describes the evolution of the PTZ cameras from coax connected analog cameras to network-attached digital cameras with much greater capability.

Technology Review of 2020

Is there anything nice we can say about 2020?  Not much except maybe, I don’t think murder hornets killed anyone. It certainly was a challenging year, and we are all happy to say goodbye.

Technology in 2020
Technology in 2020

It was a year of the pandemic and of science finding vaccines in record-breaking time.  It was a year where we worked at home and discovered we could do this anywhere in the world. It caused an upheaval in the real estate market as we moved out of big cities and corporations downsized. SpaceX changed how we went to space, and engineers developed face recognition panels that checked our temperature as we entered the building. 

This article reviews some of the technology for the security and surveillance market introduced in 2020.

IP Paging Systems Provide Advanced Functionality

This is Not Your Father’s Paging System

Paging systems have changed over the years.  Remember the old days when the principal would make announcements on that old PA system. You were lucky to hear anything that was said.

Paging Over IP

The principal had a microphone attached to a clunky amplifier. It had a large knob that adjusted the volume. All the speakers were wired to this central amplifier. Many of these old paging systems have reached end-of-life, and people are looking for replacements.

The world of paging systems has changed. Now, it’s all digital. This evolution has made paging systems much simpler to install and provide new functions that were not available in the older systems.

These safer practices increase the overall security of the system.

System security starts with the correct type of door-reader and secure wiring. It requires the right electric lock and an exit methodology for maglocks. It is also essential to select the right management software and additional security and safety features.

An access control system allows people with a credential to enter, but what happens when a visitor comes to the door?  One easy way to handle the visitor is to add an IP intercom.  An IP camera, and some additional software, can be added to provide a safe way to allow visitors to enter. This article describes how you can enhance your access control system.

How a Power Supply Works

Access Control, IP Cameras, and Intercoms Need Power Supplies

Designing a power supply is one of the first electrical engineering tasks I did in college. I remember those days. We learned many things, such as don’t drink a lot of beer before the lab class. Don’t put your finger in the electric socket. Always try to guess what’s on the test. And, stay away from courses about antennas because they were terrifying. 

Power supplies are in computers, IP cameras, access control systems, IP paging, and intercoms.  It is one of the most underrated components of a computer system. When you specify a computer, you think about the processor speed, the memory, storage, and display card. The power supply is never considered.  Of course, if it fails, none of the other components will work. Sometimes it’s the most unsophisticated part of the system that is the most important. Does anyone remember the old joke about the argument between the various parts of the body*?

Integrating Access Control and Temperature Screening

How to Integrate Temperature Scanning Biometrics with Access Control systems

Access control systems can be enhanced to increase safety by adding biometric (face and Palm) access credentials, temperature scanning, and mask detection. The biometric temperature scanning panels can be used by themselves or added to existing access control systems.

Why add biometric access control? Mostly because it provides better security. A card credential can be stolen, forgotten, or even copied. Even though my mother told me that I could lose my head if it weren’t attached to my shoulders, I’m sure that I will have my head (and face) when I get to work.  The face recognition or palm readers provide a very secure way to provide identification. One other thing about biometrics is that you don’t have to purchase cards or keyfobs for all the people in your organization. A typical card credential can cost over $3/credential, so if you have 500 people in the organization, it can save you money.
