The changes in video technology over the last several years has been outstanding. Breakthroughs in technology have produced better and better equipment while dramatically lowering the cost.
Recording equipment has evolved from analog tape to digital recordings. These digital recordings can be highly compressed so that they take a fraction of the space to save and perhaps even more importantly take a small fraction of the bandwidth to transfer from one location to the next.
This reduction of needed bandwidth combined with the increase of bandwidth provided by common internet access services has created hundreds of new uses for Video.
Two applications that now affect most of us are in communication and security. Video conferencing has become common both for commercial and noncommercial uses.
It is now very common to hear about grandkids calling up Grandma and Grandpa on the computer and actually being able to see each other due to video conferencing (web Cams). Companies are holding meetings with divisions around the world in real time.
But there is a learning curve. using this technology requires learning what is available and how to use it.
And thus sets the stage for my Video Technology lens.
This is a huge subject that will require updating this lens frequently, so stop by often!

Video Question - What is a DVR?
A DVR is a Digital Video Recorder. In many ways this is like a specialized computer. It stores video digitally like your computer would.
This allows the video to be compressed so that it can be stored taking up less room and making it easier to send over the internet.
Choosing a video cable
There are 2 main categories of cable used for the transfer of video signals.
1)RG59
2)RG6
Both are coaxial cables (coax), which is the round cable that has a center conductor and a shield.
Which cable you use is determined by the application and the distance to be traveled. Both have very similar characteristics and are both suitable for use as a cable to transfer signals from a video camera to a recording devise.
RG59 is a slightly thinner cable and usually less expensive. This is usually the cable of choice for video applications.
RG6 is a heavier cable that is better suited for higher frequencies such as broadband CCTV and satellite systems

"Capture video in low or even no light conditions"
Low light Video Cameras
"There are several methods that can be used when trying to capture video in low or even no light conditions." - Video Surveillance Systems
In low light conditions, such as when trying to capture video at night under street lights, normal low light cameras can often take satisfactory video. However in very low light conditions other equipment should be used.
One option is the "StarLight" camera. These cameras are 30x more sensitive to light than standard low-light cameras. And really can give a good video signal by only star light or at about .0003 lux.
When lower or even no light conditions are required the addition of infrared illuminators are necessary. These illuminators produce a light that is below the ability of humans to see, but make the landscape quite easily visible to video cameras

Custom Video Solutions
Portable Security Trailers
Video security doesn't get much better than this!
Much thought must have went into designing this custom video solution. With three fixed cameras and a pantilt color camera this Video Solution has a 360 degree view.
Motion detectors click on Lights and an audio warning system.
This system can be easily collapsed down so that it can be towed behind a car.
Best part of this system is that it is connected with a wireless internet connection allowing the creators to view the cameras from anywhere in the world in real time.
Here are some more pictures of this portable security trailer.

Video Classrooms
Another way Video Technology has been used is for remote training and classrooms. Corporations, colleges and universities have all started offering online classes on almost any subject you could want. In addition to this many large companies are finding this to be a useful way to provide continuing education to their employees.
Remote learning programs reduce the need for travel and the expenses surrounding more conventional training methods. Employees can sit in there own office and attend seminars and training classes. Software has also been developed that allows for interaction between the student and the teacher in real time. Students can type in questions that the teacher can refer to and answer as needed.
