Having a PAL to NTSC video convertor on hand allows you to watch videos on your current TV and DVD system even in the presence of a PAL-NTSC conflict. First, we shall define the relevant terms and explain the issue that this kind of tool resolves.

Different countries in the world utilize either NTSC or PAL analog television systems. Most nations use PAL or Phase Alternating Line format. Meanwhile, countries such as Japan, South Korea, Taiwan, Canada, the United States, and some territories in South America use NTSC or National Television System Committee format. A third system, which we will not discuss here, is SECAM, which is popular in Western Africa, Eastern Europe, and France.

Domestic and commercial intruder alarms and CCTV systems are some of the basic components of modern electronic security systems. The range of options has increased significantly in recent years. These days, the most advanced solutions for businesses and organizations are state-of-the-art hardware and software that offers both remote and direct access to users. These systems are monitored from a central control system.

The need for better security measures

People with criminal intent are finding new ways to overcome security systems, using advanced technology to crack codes and gain access to control systems. Outdated intruder alarm systems are insufficient in protecting human life and property. Consequently, it has become a necessity to install new security solutions with monitoring schemes offering video and alarm receiving and response centers. Business owners are favoring solutions that also include operation and management services that provide 24/7 security.

A transformer is a device made from core of soft iron with two or more insulated coils of wire, which are not connected. The main function of a transformer is to change the voltage or alternating potential difference from one state to another. The voltage is increased or decreased via a process that involves electromagnetic induction. The name of the device is taken from its main function, which is to transform voltage.

How does a transformer work?
A transformer is a voltage ratio device primarily because the amount of transformation is dependent on the turn ratio of the two sets of coil. The primary winding or input coil magnetizes the core when an alternating voltage is applied. The first coil affects the secondary winding or output coil. When the core is magnetized, voltage is induced in the secondary coil by the changing magnetic field. The ratio is 2:1 if the primary coil has 100 turns and the secondary coil has 50 turns.
