Surveillance is the monitoring of behavior. Systems surveillance is the process of monitoring the behavior of people, objects or processes within systems for conformity to expected or desired norms in trusted systems for security or social control.

There's nothing better than wearable spy equipment when performing a secret surveillance operation. Surveillance systems enable you to observe multiple locations through one localized system. With a digital video recording system, your security cameras are set up in different locations and interconnected so you can view all the areas at the same time. There are different types of surveillance equipment

Audio Surveillance Equipment

The purpose of an audio surveillance device is to enable you to secretly listen into and record conversations that take place at a particular location or on a particular telephone line. These devices are divided into two main types:

1. Wireless i.e telephone transmitters

2. Wired devices i.e recorders, telecorders, wall contact microphones, wired microphones etc.

Telephone Surveillance Equipment

The most commonly used telephone surveillance equipment is transmitter. Clearly monitoring both sides of a telephone conversation, the discreet range of Phone Transmitters are easily installed on a telephone line, in a socket, or in the instrument itself. Telephone Transmitters are surveillance transmitters that become operational when the telephone is in use and give no indication of their presence to the telephone user.

Another most commonly used telephone surveillance equipment is telephone recorder. It connects to the phone line, your tape recorder's microphone input, and the recorder's remote control jack. It senses the voltage in the phone line and begins recording when the line drops to 5 volts or less.

Counter Surveillance Equipments

Counter surveillance is the practice of avoiding surveillance or making surveillance difficult. As people and businesses alike become more and more aware of the growing problems regarding personal and professional privacy, bug-sweeps and other Counter Surveillance Measures have, for some, become an extremely important part of life in today's world.

Bugging Devices and Telephone Taps are an effective means of finding out what competing businesses are doing, and such a practice has become more and more common.

Hidden cameras have become very popular in recent years. Business owners often use surveillance equipment to keep an eye on employees or their store; they can help to protect the business from theft, vandalism, or just for keeping an eye on things. Parents can use nanny cams to make sure their children are being properly treated while they're away.

Karaoke Machines

One invention that has really taken off in the music world is the karaoke machine. Unlike other pieces of musical equipment, this one appeals to folks of all ages, all genders and all types of voices - good or bad!

Here's a quick guide to singing with programmed music, and how it's progressed over the years.

A Brief History of Karaoke Machines

The earliest karaoke machine was invented in Japan during the 1970s when a singer named Daisuke Inoue developed a tape recorder that could play a song for a 100-yen coin. He had been asked frequently by attendees of his performance to provide his song on a tape recorder so they could sing along during a company vacation.

Daisuke felt it was a great idea, not for his song only, but for many others. Inoue leased his recorders to stores instead of selling them directly.
The machines were placed in restaurants and hotel rooms. In 2004, Inoue won the tongue-in-cheek Ig Nobel Peace prize for his invention.

Karaoke Hits the USA

Karaoke machines came to the United States during the 1990s when bars, also called KTV boxes, began having competitions or fun nights for amateur singers.

Advancement

The early karaoke machines worked with cassette tapes, but later became more advanced using CDs, laserdiscs, VCDs and today's DVDs. The machine has audio input, audio output, and a way to alter the pitch of the music. The most popular ones are audio mixers that include a microphone input that's built in with a Laser Disc, Video CD, CD+G or DVD player. Karaoke machines that are capable of producing a video lyrics display are called KTV in many countries.

Another unique feature is the ability to change the pitch of the music, or key, to fit the vocal range of the singer. With this feature, songs that are too high for the singer can be played in a lower key.

Computer Generated Songs

Karaoke songs are now being played over computers everywhere via music files such as MIDI, MP3 and many others. The machines are not needed with these files, but a downloadable karaoke player instead. Both the players and song files can be downloaded on the Internet.

More Advances are Coming

Karaoke machines are being modernized in many other ways as well. From auto karaoke to mobile phones, people are going to be able to "sing along" from just about anywhere before long!

Still Going Strong

Even with all the modern devices and methods of entertainment, the karaoke machine will still be around for a while. You'll find them in restaurants, bars, gatherings and other public places holding singing competition because they can be moved easily, use a screen and sound everyone can see and hear when a big crowd is present, and they provide affordable entertainment.

So, don't look for this Japanese invention to go away anytime soon.
