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.

Technical Jokes and Cartoons-81

Every truth has two sides; it is as well to look at both, before we commit ourselves to either.


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.

IP Camera Systems for all Occasions

IP Cameras for Many Applications

IP Camera Systems
IP Camera Systems for Everywhere

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.

This article describes the specialized capabilities of today’s IP camera systems

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.

Technical Jokes and Cartoons-80

A bunch of evolutionary scientists got together for a cookout one day.

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.

How to Select the Right IP Camera System

Using the Right IP Cameras Ensure an Effective IP Camera System

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.

Cookwitch Sandwich

Shel Silverstein

I heard that Katrina
The Cook was a witch,
But me, I’m such
A stupid kid,
I yelled, “Hey! Katrina,
Make me a sandwich,”
and ZAP —
She did!

Jack: My uncle swallowed a frog.

Jill: Goodness, did it make him sick?

Jack: Sick! He’s liable to croak any minute!

What do you call a small bread that is moving rhythmically to music?

Scalable Door Access Control

Access Control One Door at a Time

Scalable Access Control
Scalable Access Control

One of the nice things about technology is that devices generally do more things and become easier to use as time goes by.  This has certainly been true with access control systems. The first door access control systems required a skilled technician to install the system. There was quite a lot of complex wiring from each door reader to the main controller box. The new IP Reader-Controllers connect to the network and are intelligent. One of the most significant advantages is the ability to install one door at a time.

This article reviews the incremental capability of these new IP access control systems.
