Do You Believe Facial Recognition Readers Store Your Picture?
There are many misconceptions about science and technology. One of the misconceptions is that biometric IP door readers store a picture of your fingerprint or face. Another one is that the Earth is a flat disc that rests on top of four elephants, on top of a turtle*.
For clarity, biometric door readers do not store a picture of your fingerprint or face, and the Earth is not flat. This article describes the technology behind biometric door readers.
Back in the 1800’s the Tates Watch Company of Massachusetts wanted to produce other products and, since they already made the cases for pocket watches, decided to market compasses for the pioneers traveling west. It turned out that although their watches were of finest quality, their compasses were so bad that people often ended up in Canada or Mexico rather than California.
This, of course, is the origin of the expression; “He who has a Tates is lost!”
A three-legged dog walks into a saloon in the Old West. He sidles up to the bar and announces:
If you want to detect an object many miles away, you will need a special long-range PTZ camera. While custom-made cameras are best for very long-range applications, the latest off-the-shelf cameras provide some of the same capability for less money. These long-range PTZ cameras are very cost-effective, and allow you to detect a person almost 4-miles away. They have built-in IR-illumination or an additional thermal imaging camera that allows you to see an object over ½ mile away. Prices range from less than $3,000 to about $25,000.

The basic difference between the off-the-shelf cameras and the custom made cameras is their performance. The custom long-range cameras take much longer to build because they use special components. The custom long-range cameras generally will provide much better operational distance, especially at night. Custom-made systems can view objects at night that are over 8 miles away. They include very long distance lenses, specialized laser illuminators, special thermal cameras, and very high-performance pan tilt mechanisms. Off-the-shelf long-range cameras cost less than $25,000, while custom cameras range in price from $50,000 to well over $150,000. Here is a summary of the systems available:
How Write-Once Storage is Used to Protect Video Evidence From Your Ip Surveillance System
One of the objectives of a video security system is to help law enforcement prosecute miscreants. It is important that this digital evidence follow the rules for chain of evidence so it will be acceptable by the courts. It must be treated just like fingerprints, confiscated weapons, and other physical objects that need to be authenticated in court. Ensuring the immutability of digital information can be challenging because a knowledgeable person can modify the evidence if it is not secured. How can we assure that the information has not been edited, deleted, or modified in any way? This article reviews some of the methods for protecting the video chain of evidence.
Procedures Required
In all cases, defined methods of handling and storing the video data need to be followed. Once an incident occurs, the organization should follow a procedure that protects the video. The first step is to transfer the video evidence to secure storage that can’t be changed. This can be DVR-R disc or a protected hard drive. Once the video is transferred, it can be provided to law enforcement.
An engineer died and reported to the Pearly Gates. An intern angel, filling in for St Peter, checked his dossier and grimly said, “Ah, you’re an engineer. You’re in the wrong place.”
So, the engineer was cast down to the gates of hell and was let in. Soon, the engineer became gravely dissatisfied with the level of comfort in hell and began designing and building improvements. After a while, the underworld had air conditioning, flush toilets, and escalators, and the engineer was becoming a pretty popular guy among the demons.
One day, God called Satan up on the telephone and asked with a sneer, “So, how’s it going down there in hell?”
How to Protect Your Computer from Ransomware and Other Malware
What if you didn’t have to worry about ransomware or any other viruses? Unfortunately, cybercrime has become a major problem for the Chief Technology Officer (CTO) who is tasked with protecting the company’s computer systems, as well as the CEO who has to deal with the consequences of an attack. Large corporations such as Merck, Mondelez, Sony and DLA Piper have been infected by malware. Hospitals and organizations around the world have not been spared. It has become a global problem.
There are a number of virus protection programs that attempt to block malware from entering the system, but none of the solutions work all the time. A good solution is to be more careful with email, but it is hard to control everyone in the organization. An extreme solution is to take the computer off the Internet, but this prevents access to people who need the data.
I was not sure what to call this article. I first thought it should be titled, “Why The Johnson Criteria is Wrong.” We use this criterion to predict how far away we can see something using a specific camera and lens. The criteria define the threshold for detection, recognition, and identification (DRI). The industry has used this criterion since World War II. It has not been updated to reflect today’s technology and resolution requirements.
What Is the Most Secure Door Access Control System?
How secure are door access control systems? Pricing can range from less than $100 for a single door to over $1100 per door. What do you get for the money? In some cases, the security level provided can be crucial to your safety.
How can we stay ahead of miscreants that are dedicated to breaking through our security systems? This article summarizes the various levels of electronic security provided by different door control systems. Level 1 provides the least overall security while level 4 provides the highest level of protection. We compared the cost against the effectiveness of each type of system.
