Monitoring visitors in large organizations is a continuing challenge. The pandemic of 2021 increased our need to improve entry control to multi-tenant buildings and apartment houses. Not only do we want to know who would like to enter, but we also want to know if they are healthy. Learn more about Apartment Intercoms…
This article describes how the multi-tenant wireless intercom works.

Nighttime is when we expect criminal activity, and of course, that’s the most challenging time for IP surveillance cameras. There are several ways of seeing in the dark, but the best way is to use an IP camera with enhanced low-light sensitivity.
The low-light capability of IP cameras has gotten much better over the last few years. We used to be happy with cameras that could see at 0.1 lux in color, but now we have IP cameras (like the PNO-A6081R) that have low-light sensitivity in color at 0.007 Lux. The camera can see at night when the stars are shining.
This article reviews the technology behind very low-light IP cameras.

After all the background checks, interviews and testing were done, there were 3 finalists: two men and a woman.
For the final test, the FBI agents took one of the men to a large metal door and handed him a gun.
“We must know that you will follow your instructions no matter what the circumstances. Inside the room, you find your wife sitting in a chair… Kill her!!”
The man said, “You can’t be serious. I could never shoot my wife.”
The wonder of eyes. If eyes are the windows to your soul, then IP cameras with their lens and CMOS sensors are the window to computer vision. Like our eyes, the sensors in cameras convert light to electrical signals that the computer can use.
This article describes how the CMOS sensor in IP camera systems converts the visual world into digital signals.

An oil rig can be a scary place. On January 22 of 2018, fear turned into reality when an oil rig in eastern Oklahoma exploded. It left many dead and injured. The accident was the result of an uncontrolled release of gas that caught fire.
It is essential to take every precaution to prevent accidents. Flammable contaminants in the air can cause explosions. Gas and dust are the usual culprits. If the concentrations are high enough, it just takes one spark to cause a catastrophic explosion.
This article reviews the certifications and standards that define what type of explosion-proof camera system should be used.

Aesop
A child asked his father, “Dad, do politicians ever tell the truth?”
The father answered, “Only when they call each other liars.”
There are only three things that tell the truth in the world
Kids, Alcoholics, and yoga pants.
These days, IP camera systems can be used in many different applications and environments. It’s not just to determine who robbed the bank. IP camera systems are more than just recording the video. They include sophisticated intelligence that can notify us of real-time alarm conditions.
Applications for IP cameras include theft deterrence, automated license plate recognition, watching wildlife, viewing the army tank that’s two miles away, or watching the inside of a blast furnace.

The Pandemic caused significant disruptions. Our economy and ordinary lives were affected. We had to rethink everything from where we worked to how we stayed safe. These disruptions led to changes in our social and commercial lives. Access control, IP camera systems, intercoms, and paging systems were used to mitigate the disruption. This article describes how the Pandemic caused an upheaval in access control and other technologies that will stay with us into the future.

They got a bunch of stuff to grill up, but everyone was most excited about the sausages.
The scientists counted the sausages to make sure there were enough for everyone, and even though they initially thought they had enough they were one short. They checked the cooler, the fridge, and everywhere else they could think to look, but science still has yet to find the missing link.
Do you think all IP cameras are the same? If you do, it’s likely you won’t be happy with your IP camera system.
There are many different cameras with different lenses, resolutions, light sensitivity, and other characteristics. These features are so important when you want to ensure that you can see everything you want to.
Yes, it takes some work to select the right IP camera for the area, but it will make the difference between security and uncertainty.
This article describes the process you can use to choose your camera and video recording software.
