What Is Audio Surveillance

headset. earphonesSo to resume my run of content on this website, I have planned to share one of our favorite articles this week. I was tentative to include it to the site because I actually didn’t want to offend the original writer, but I trust he/she is happy that I enjoyed reading their work and wanted to share it with my readers.

Audio surveillance is the act of listening to third-party conversations and recording them. This technique is frequently used by law enforcement, private detectives and government spy agencies. Most audio surveillance consists of either bugging a room, wearing a wire (walkie Talkie Headset), tapping a phone or distance listening. Each provides distinct advantages and disadvantages, depending on the situation.
Wiretapping is one of the most common and simple form of audio surveillance. This is preferred because it is highly inconspicuous and allows for two sides of a conversation to be clearly recorded. Small audio devices, commonly called bugs, are attached to the internal circuitry of a telephone to pick up a conversation. A signal is wirelessly transmitted to another device that records the conversation. The drawback of this method is getting access to a subject’s telephone to properly wiretap it.

A room microphone is another audio surveillance technique that often is utilized. This involves planting a wireless microphone in a room to pick up conversations. Disguised room microphones are available to look like pens, clocks, stuffed animals and a variety of other covert forms. This microphone sends a signal to a receiver, just like a wiretap does, and the signal can be directly recorded. The disadvantage here is access to some rooms and getting only one side of a phone conversation if it takes place in that room.

Concealable transmitters known as body wires are well-known devices that have been featured in many television shows and movies. A small microphone and transmitting device are worn under the clothes of a person in order to send a signal back to a receiver and record a conversation. This allows the person wearing the wire to ask questions and get specific details that simply listening to other people’s conversations could not provide. The disadvantage of this method is getting access to the person needed to be recorded and also concealing the microphone in a way that hides it but allows for clear recording.

Long-distance microphones are another covert means of audio surveillance. A parabolic microphone, often called a shotgun microphone because of its long shape, has a powerful ability to pick up conversations up to 300 feet (91.4 m) away. Its main disadvantage is its high sensitivity. It can pick up other noises and cannot function if obstructions, such as trees and automobiles, are between the microphone and the conversation.

Can the Megaplex Survive the iPhone?

I adore to understand more about writing on blogs, I’m a self-motivated individual. My interest is surfing on several informative blogs about Radio Accessory that facilitates me on improving my writing ability.

In an era where Video on Demand (VOD), near simultaneous DVD releases and now downloads to smart phones, the question is, can megaplexes survive the iPhone?

There are nearly 600 films released in the US every year. Many end up in the megaplexes. Some end up in your local art house or museum theater, some end up a VOD and some even can be downloaded to your iPhone, so you can see them while ignoring fellow mass transit riders.

Early last summer, the indie market was abuzz when prophets of gloom predicted the end of the independent feature film. Several small or boutique distributors either went belly or were swallowed up by their much larger brethren. The options for filmmakers were getting smaller.

Over at the megaplex where Hollywood’s latest popcorn films or chick flicks vie for the dubious and very transitory distinction of being the “#1 Film in America”, there is also a sense of gloom. Yes, gross sales are up this year. Many exhibitors are thankful for the recession They are convinced hard times make movie going affordable. Obviously they don’t buy their own concessions. But the studios and the exhibitors of all walks are on the same page. The way out of gloom is to look to the future and the future is digital. Economic well being will be assured and in the 3D. Despite the future bravado, actual attendance is at best the same. Inflation is the difference.

This is a quick view of the landscape. Both megaplexes and independent theatres see trouble on the horizon. They see VOD and even new platforms like cellphones as threats. The question asked earlier was, “Can the megaplex survive the iPhone?” The answer is simple, yes.

In the past Hollywood has fought television, then cable television, then the VCR, and then the DVD. They will fight anything new. Hollywood has more conservative thinkers than the last Republican. There will be many voices in La-La Land bemoaning the end of exhibition or the end of indie films, but nothing could be further from the truth.

When VCRs came around, not only did Hollywood find a new economic model spewing cash, new fans emerged. When DVDs established themselves, Hollywood found an amazing source of revenue, nearly twice as much as domestic exhibition with n near the cost. It was found money. They went from gloom to laughing all the way to the bank.

Both factors will come into play with new technologies – new audiences will be found and new revenue streams will flow. The megaplex will survive as will the independent theater. Both just need to be smart about what they do. One word of advice, embrace the new technologies. They are here to stay.
