A lot of people wonder what is the difference between the analog and digital TV? The answer is the way the signal is transmitted. The signal of analog television resembles very much to radio signal transmission, with one difference: the video signal of analog television is AM and the audio is FM. There are many negative aspects of analog signals, and one of those is that there can be annoying interferences in bad weather, and signal quality depends very much on the location of the TV.

The resolution and image quality are also restricted, because there are certain bandwidths assigned to analog TV channels. The analog signal is the United States follows the NTSC standard. This had been adopted in the 1940′s, and served well since then, but nobody thought at that time that about color television. One major weakness of the NTSC standard is color implementation, so it is no wonder a lot of people call “Never Twice The Same Color” the NTSC standard.

Digital TV has quite a few advantages over analog signals. Digital signal is very much like computer data flow. There are two kinds of signal: 0, and 1, meaning “on” and “off”. The user sees the image or not. This is why in the digital era gradual signal loss and interference is unknown. And it doesn’t matter how far away the transmitter is.

Digital format was thought with all the main factors of present-day television signals in mind: B/W, color and audio can be transmitted as interlaced or progressive signal. This means the signal content has greater integrity and flexibility.

The same bandwidth an analog TV signals requires can host higher quality digital image and there will be even extra space left, which can be used for extra video, audio or texts signals.

This way broadcasters using digital technology can supply more features, like surround sound, multiple language audio or text using the same bandwidth a standard analog TV signal requires. Digital TV has one more advantage: it is able to transmit High Definition (HDTV) signal.

With this technology, programs using true wide screen format (16×9) can be broadcasted. The 16×9 format means the shape of the picture corresponds to a movie screen. Viewers can forget about the black bars on the top and the bottom of the wide screen image, being able to watch movies the same way filmmakers wanted to be seen. Sports fans can also see more action, and with 16×9 format it is possible to view the entire football field, without the sensation that it is far away.

Digital transition in the United States took place on June 12, 2009. On this date all analog TV signals went dead, and every analog television became useless without an analog-to-digital converter. Originally the digital transition was scheduled to 2006, but authorities postponed it because they were afraid the consumers are not ready.

If no camera was present, catching an escaped criminal could be close to impossible and left only up to the memory of those present at the time. As this is likely to return little or no result in the capture of a criminal, security cameras are necessary in order to get a confirmed visual of the suspect. The tape from security cameras are turned in to the police after a robbery, and are then used to attempt to confirm the identity of the suspect. Depending on the scale of the crime committed the tape may even be played on the news to see if any viewers recognize the criminal. Everyone has watched the news and seen low quality images or videos of criminals robbing banks or committing even worse crimes. These tapes are taken from video surveillance of the affected location.

Installing superior quality cameras on the essential locations is very important to secure lives and properties. If the building or an establishment is big, installing few security cameras may not be sufficient to cater the needs for security. There are some areas might not be captured by the video cameras. And another thing is, big room with a little camera will only lead to poor image quality and will be useless for investigators for their investigation. Just like in parking lots, if a poor quality camera is put,most likely it will have a big probability that it will lead to some accidents .It is important to remember that when capturing a large area, good quality camera is needed to have a good output . Security cameras location should be put on the areas where the face of the suspect can be identified.This can be a suitable evidence for the capturing the suspects and will be helpful for investigators.
