There are a variety of network-attached intercoms. Some connect to a central computer, while others connect to smartphone apps. The new IP intercoms use your network infrastructure, are powered over Ethernet (PoE), include IP cameras, and have great features and functions that were never available with the old analog intercoms. They can open doors, integrate with IP camera systems and door access control systems to provide a complete security system.
In general, IP intercoms consist of an audio amplifier, microphone, I/O connections, a special-purpose computer, and an interface to the network. This article reviews the different models of IP intercoms and how they can be used.
A Girl Potato and Boy Potato had eyes for each other, and finally, they got married and had a little sweet potato, which they called ‘Yam.’ Of course, they wanted the best for Yam. When it was time, they told her about the facts of life.
They warned her about going out and getting half-baked, so she wouldn’t get accidentally mashed, get a bad name for herself like ‘Hot Potato,’ and end up with many Tater Tots.
Yam said she would stay on the straight and narrow and wouldn’t associate with those high-class Yukon Golds, or the ones from the other side of the tracks who advertise their trade on all the trucks that say, ‘Frito Lay.’
Mr. and Mrs. Potato sent Yam to Idaho P.U. (Potato University ) so that she’d really be in the Chips when she graduated.
The combination of access control, temperature scanning, contact tracing, and access to control databases has increased security and health. This article reviews the new technology advances in visitor management and the integration of door access control and other technologies.
Pan, Tilt Zoom Cameras Provide Increased Capability
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.
The latest IP apartment intercoms use wireless networks to communicate with the tenant. The new wireless multi-tenant intercoms allow you to contact the resident’s smartphone or standard phone to request entry into the building. The lobby intercom touchscreen display provides a list of all the tenants in the building.
This article provides critical features and functions of the best apartment intercom systems.
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.
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.
What’s the difference between a home surveillance camera and a commercial IP camera system used in schools, office buildings, and hospitals?
Home IP Cameras cost between $20 and $100, while the professional IP cameras range from $150 to over $2,000. There is a difference. This article compares the capability you should expect from a home camera versus a commercial surveillance IP camera 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.
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.
