Concerts, entertainment shows, and musical performances are all events which have a significantly large audience from all types of backgrounds with varying age group ranges. When it comes to large aggregations of people, it is always wise to monitor their location and surroundings using security cameras. These surveillance devices are composed of the actual security cameras , a security monitor device (this can be a TV screen or a computer monitor), and some sort of media storage device (it can be video tapes, DVRs, or the hard drive of a computer). The price of these systems has gone down drastically over the past few years, thus, enabling various businesses as well as the general public to obtain them with affordable prices.

The safety and security of any country should be the primary concern of its government. A close eye should be kept on the methods and locations of entry as well as regression from a country, whether by land, sea, or air. Addressing the national security problems and concerns will only prove to be successful upon seeing the holistic magnitude of the situation. A great deal of attention has been poured on airports and airport security, especially after the unfortunate events of September 2001 in the United States. Fortunately the rapid advancements in the field of security technology have greatly assisted in preserving a high level of airport security throughout the nation.

By monitoring the airport and passengers for any suspicious activities, security cameras will assist any country in fighting their number one common enemy, terrorism. The danger of terrorism goes far beyond the walls of the airport, but airports and other modes of transportation facilities are usually the first checkpoint to enter into any country, if the perpetrators and other criminal doers slide easy past this vital checkpoint, there is no telling of what could happen to the innocent civilians of that country. Further more, airports and other transportation facilities, themselves, can be a target to terror attacks. A frequent trend has been spotted in most terror attacks, and that is that they all tend to target places with massive numbers of people, which makes all mass transportation vehicles and all buildings an easy target for evil doers.
