Security Camera Mysteries: What is NTSC? Technology Articles | February 24 Cheap Sean Elliott Jersey , 2010 Are you interested in augmenting your security system with a camera from a different country? Here's one article that you absolutely must read before heading to the shopping sites!
More people than ever before are now security-conscious in ways they may not have been just a decade ago.
However, awareness of the need to guarantee security in buildings and even homes has meant that the popularity of security camera systems has never been higher.
There's no great mystery to these cameras, though understanding the ways in which they receive or broadcast signals such as NTSC is important.
Standing for "National Television System Committee Cheap David Lee Jersey ," NTSC is the authorized analog broadcast encoding system for much of the Americas (except for Brazil and a few other countries), Japan and South America and a couple of smaller SE Asian nations.
Though most of the world is now moving to digital broadcast signals, it'll still be the case that NTSC or its European counterpart PAL ("Phase Alternating Line") electronic equipment like televisions and cameras will be quite common.
Knowing something about not only the region in which the security camera system is going to be used by also how those two systems (there are actually 3 different analog systems Cheap Rudy Gay Jersey , with the other being called SECAM) process their analog signals can be vital, if only to make sure the right set of cameras is being used in the right region.
The main thing to remember about NTSC is that it has a way to control tint so that correction of color can be corrected manually.?
PAL doesn't. NTSC also has a different line and refresh rate, meaning that the picture signal refreshes on a different scale than does PAL.
Much of this has to do with what's called "frame rate conversion Cheap Pau Gasol Jersey ," NTSC cameras run frames at nearly 30 frames per second versus the slower 24 frames per second in an NTSC camera.
Because of this, some claim that NTSC cameras can capture more of the action and that it'll be sharper, though the naked eye really can't tell the difference.
Most security experts would say that the big benefit would be when any videotape is reviewed frame-by-frame Cheap LaMarcus Aldridge Jersey , of course. If there are more frames, there's more information, in other words.
It's usually not advisable to mix or mingle cameras that feature different methods for decoding and encoding analog broadcast signals Cheap David Robinson Jersey , such as one would find in PAL and NTSC cameras.
In some cases, a single camera inserted into the system can throw off the whole system. In other cases, signal quality will be degraded though not enough to completely ruin the quality of the images created.
It's easy enough to tell the difference between PAL and NTSC cameras.
One only need look at the equipment Cheap Tim Duncan Jersey , which is required to publicly declare on a label or advisory that it is either PAL or NTSC or able to make use of both systems.
Neither system is usually seen in the other's broadcast region, though, so any mix up would almost have to be deliberate in order for it to occur.
Digital broadcasting and encoding systems are gradually taking over the marketplace Cheap Kawhi Leonard Jersey , so expect to see the gradual disappearance over time of analog equipment capable of sending and receiving these signals.
Pablo Picasso, was once asked by a journalist "what does it feel like to be Picasso, master of the arts?"
Picasso slowly reached into his pocket and pulled out a dollar bill.
He took a pen in his hand and signed the dollar bill before handing it to the journalist.
The famous painter then remarked "that dollar bill is now worth $ is what it feels like to be Picasso!"
Every time I recall that story it makes the hair on the back of my neck stand on end. For me Cheap San Antonio Spurs Jerseys , it's a constant reminder of the rewards that flow from spending a lifetime dedicated to what you are truly good at.
So what's your Genius?

Take a moment to think about the 3 things you do best (no reading forward until you have them - close your eyes if you have to!)

2.
3.
You should also consider asking your three closest friends what they believe you three greatest talents are. Compare their answers with your own. It just might surprise you!
The Entrepreneurial Challenge
One of the biggest challenges every entrepreneur faces, particularly when starting out in business is trying to be good at everything (no lecturing here - I'm actually working on this one myself!).
But consider what would happen to your business if you could completely flip this one around? What could you do to focus more of your time on the things you are truly good at? How could you attract people to do the things that you don't have a natural talent for?
Employee Performance Appraisal
If you've ever worked as an employee, chances are that you've had to endure a typical performance appraisal. You know the ones I'm talking about. Where you spend a couple of minutes talking about the things you've done well and then a couple of hours talking about all the things you need to improve upon. Often the result of this kind of approach is that you spend the following six months focusing on all the things you aren't good at Cheap Spurs Jerseys , sending your motivation into freefall. Can you imagine the collective effect of this approach where entire organisations are in a similar frame of mind?
