Some days I amaze myself.

Do you need to view a rocket launch or the inside of a blast furnace? The usual IP camera systems won’t survive these extreme conditions. These applications require a special camera enclosure that is designed for these extremely hot environments.
This article describes how high-temperature camera enclosures are made.
Thermal and optical IP cameras use different technologies to capture video. Each type of camera system provides a unique role in an IP video surveillance system. Systems that combine thermal and optical cameras provide a synergistic solution for long-range surveillance.
Thermal cameras are better for night viewing since they don’t require any light. The optical IP cameras require daylight or illumination at night and are best for identifying details such as a person’s face or a license plate number. This article describes when to use these camera systems.

On the last day of kindergarten, all the children brought presents for their teacher.
The florist’s son handed the teacher a gift. She held up the box and said, “I bet it’s some flowers!”
“That’s right!” shouted the little boy.
Then the candy store owner’s daughter handed the teacher a gift. She held up the box and said, “I bet it’s some chocolates!”
“That’s right!” shouted the little girl.
The next gift was from the liquor store owner’s son. The teacher held up the box and saw that it was leaking. She touched a drop with her finger and tasted it.
“Is it wine?” she asked.
“No,” the boy answered. The teacher touched another drop to her tongue.
“Is it champagne?” she asked.
“No,” the boy answered.
“What is it?” she said.
“A puppy!”

There are different methods used for matching facial biometrics. The simplest method measures various features of a person’s face, such as the distance between the eyes, or the position of the mouth to the nose. These geometric measurements or vectors are then coded and stored in a database for later comparison. This type of system is usually used in biometric door access control readers.
How much should you expect to pay for your IP camera? IP cameras range in price from under $200 to over $1000.
Since the price depends on what you need, you should always make sure you understand your objectives. For help in defining your requirements, take a look at our article, Defining Your Objectives.
Price varies with performance. The least expensive cameras have fixed lenses. Do you need a camera for a small room or an outdoor camera that can recognize a person over 300 ft. away? The more expensive cameras include variable lenses that you can adjust from your computer. Some high-performance very low-light outdoor cameras can see things by starlight.

When seconds count, a single-button alert system is essential for your organization’s safety. Whether you need to establish a lockdown or let everyone know about a fire, the rapid notification capability is important.
Emergency alert buttons can be placed at various parts of the facility and connected to your IP security system. This means you can provide different responses depending on the location. You can also have unique buttons for specific emergencies. For example, you can respond to a fire or establish a lockdown depending on the button pushed. Here’s how it works:
It was a dark and threatening day. Thunder could be heard in the distance. Fog blanketed the building, weakening the remaining daylight. Strange sounds were heard in the basement, and the security center was called to investigate.

A man walks into a bar and sits on a stool. After being served a beer, the bartender leaves the bar and goes into the back room. The man is alone in the bar, sipping his beer when he hears, “You’re looking pretty good. Have you been working out?” The man looks around and doesn’t see anyone.
He turns back to his beer and hears the voice again, “That’s a nice shirt. It goes well with your pants.” Again the man looks around and doesn’t see anyone.
When the bartender returns to the bar, the man says, “The funniest damned thing has been going on. Someone seems to be talking to me, but I can’t see anyone.
“Oh that,” says the bartender. “It’s the peanuts. They’re complimentary.”
