Detection, Recognition, and Identification – Thermal vs. Optical IP Camera

Posted on June 21, 2016March 22, 2020 by Bob Mesnik

Resolution required for Recognition, Detection, Identification depends on the type of camera

By Bob Mesnik

There is some confusion in the industry about how much camera resolution is required to detect an object, recognize the type of object, or identify exactly what or who it is. The criteria are different between thermal and optical cameras. Resolution for thermal cameras and optical IP cameras are measured differently.

For example, when defining the performance of a thermal camera we use the Johnson Criteria of “detection”, “recognition” and “identification” (DRI).

On the other hand, IP camera resolution performance is usually defined by the number of pixels in the sensor, and we are usually interested in the ability to identify a person.

How much resolution do you need? This article compares how resolution is defined using thermal and optical technologies.

How to determine the resolution required for your IP camera system
By Bob Mesnik

How much resolution do you need? It depends on what you need to see. Do you want to identify who stole your car, or just see that there’s a dog in your yard again.

It’s very important to first determine exactly what you want to see, because it will affect how much your IP camera system costs.

This article reviews the amount of resolution required to recognize objects such as people, vehicles, license plates, or even a small crack in a wall.

How Power Over Ethernet Works

PoE makes installation very easy

By Bob Mesnik

This article has been updated on 10/4/2018 to reflect the new PoE injectors available.

Many network-attached devices, such as IP cameras, VoIP phones, WiFi radios, and IP door readers use power over Ethernet (PoE). The single network cable transfers both data and power to the device making installation very simple. The data uses one set of wires, while the power uses another set of wires in the network cable.

The real art of conversation is not only to say the right thing at the right time, but also to leave unsaid the wrong thing at the tempting moment.

The older you get, the tougher it is to lose weight, because by then your body and your fat have gotten to be really good friends.

The easiest way to find something lost around the house is to buy a replacement.

He who hesitates is probably right.

If you think there is good in everybody, you haven’t met everybody.

If you can smile when things go wrong, you have someone in mind to blame.

An IP Prescription for Hospitals

How IP Camera Systems and IP Access Control Systems Increase Safety in Hospitals

By Virginia Fair

The following appeared on NBCLA.com, the website of the Los Angeles NBC affiliate station.

“A man who allegedly dressed as a nurse to fool security personnel was arrested for stealing medical supplies from a Fountain Valley Hospital, police announced Monday. The suspect is accused of stealing from Fountain Valley Regional Hospital three separate times since May.”

Fountain Valley Regional Hospital is not alone. According to the 2012 Crime and Security Trends Survey, underwritten by the Foundation of the International Association for Healthcare Security and Safety (IAHSS), the crime rate of hospitals rose by close to 37 percent in just two years, from slightly less than 15,000 in 2010 to over 20,500 in 2012. This increase occurred in all crime categories: larceny, theft, simple assault, vandalism, rape and sexual assault. The highest-ever number of homicides occurred, as well, with 8 reported by responding hospitals.

Challenging Real Time Applications for IP Cameras

Interview with Todd Vohs of Holstein AG Services About IP Camera with WDR

by Virginia Fair

In our thirty years of being, Kintronics has had the pleasure of doing business with the armed forces, the education sector, library systems, and businesses of every stripe and niche, not to mention quite a few enterprising individuals intent on monitoring such natural phenomena as:

salmon swimming upstream
seals in underground caves
eagles nesting in trees
Hawks perched in New York City’s famed Washington Square.

However, we rarely get a chance to see any of our IP cameras in action once they leave Kintronics. That was, until we had the pleasure of doing business with Todd Vohs of Holstein AG Services. He’d consulted with Keaton Baker, one of our sales engineers, in February, for suggestions about a camera that would help him overcome lighting problems he was encountering in monitoring his warehouse out in Iowa. Keaton recommended an IQ862, a camera with Wide Dynamic Range.

The Difference Between Jukeboxes and CD/DVD Servers

CD Servers, RAID, Optical Disc or Cloud Storage? That is the question
by Dennis Gallen

“What’s the difference between a jukebox and a CD/DVD Server?” That was the question we used to get. It was a time when CD-and DVD discs were a great way to archive data. Today the there are a number of different storage options available. We continue to get questions about the best way to store data. We are asked, “What is the difference between Cloud storage and optical disc storage? And, “What is the difference between tape and optical discs”?

How to Comply With the Archiving Regulations Without Paying an Arm and a Leg

Optical Archiving Libraries make it easy to protect your data.
by Bob Mesnik

So you are being dragged kicking and screaming to archive your e-mails and data. What can you do that doesn’t cost an arm and a leg? Well, the new jukebox library systems with the latest 100 GB media are now an economical alternative to tape, and provide the best way to archive your data.

The library software makes the jukeboxes easy to use so you can archive your data quickly and automatically. Blu-ray media is now the same price per megabyte as the tape media, and provides archive quality that’s not available with tape.
