Everything You Always Wanted to Know About Wireless Hidden Cameras and Maybe More!

Larry Zolna asked:


You are thinking about purchasing a wireless hidden camera but, like many people, are afraid of electronic products. You keep reading about words like “lux” and “camera resolution” and “line of sight” — do I really have to know what these mean? And, isn’t the wireless hidden camera hard to install?

The answer is NO and I’m going to tell you how easy it is to install and use your wireless hidden camera. I will also explain some of the “difficult” terms in plain, understandable English so you won’t be intimidated any more.

The best thing about a wireless hidden camera is just that — it’s WIRELESS! You won’t have to run any wires through your walls or under your rug.

These wireless cameras are called “hidden” because they are built into an existing everyday object that you see in your home or office. Most of these objects are functioning electrical appliances, e.g. clock radios, cordless phones, and even computer speakers.

Each object contains a wireless camera. The camera will function as long as the object is plugged into the wall outlet. For example, even when you turn your radio off, the camera is still working! These objects look natural when plugged into the wall, so your camera remains hidden and unsuspected.

Don’t forget — the object in which your camera is hidden is usually portable, e.g. clock radio. So even if you disconnect the plug from the wall — perhaps to move the object — you can still use your wireless camera with batteries. The batteries work for about 4-8 hours, so it’s best that you have another set handy or use a battery charger for a fresh supply.

You want to purchase a wireless surveillance camera system that is “Plug and Play.” This means just what it says — plug it in and begin using it! Your wireless hidden camera comes with 2 main components: 1) a camera and a transmitter connected inside an everyday object; and 2) a receiver which is attached to your VCR or TV. That’s all there is to it — you’re now ready to record!

Record what? There are unlimited uses for your wireless hidden camera.

How about as a hidden nanny camera — you can watch your children while they are being cared for by their nanny or baby sitter. What about your mother or father who is getting up in years and needs special care. Wouldn’t it be great to know who’s on your property all the time or even at the door? And how about your children — you can keep an eye on your tots with your hidden nanny camera to make sure they don’t leave the house or property. And, now with your small security camera, you will know the real time your teens return home at night!

By using wireless hidden cameras in the workplace, you will always be aware of what’s going on in your store, office and warehouse. Just set up a hidden camera to view your cash register, entrance and exit doors, loading dock, or just about anywhere.

All this and much more can be viewed from your VCR tape or live on your TV. And, with special software, you can watch what’s going on in your home or business on your computer screen, even when you’re away.

Should you choose a Black and White (B/W) or Color Camera? That is a personal choice that you should make. A Black and White camera does better as a low light wireless camera than a color camera because it has a lower lux. Color Cameras, however, would be more helpful to the police in identifying the burglar, shoplifter, assailant, etc. by giving a better description — for example, “the man with red hair in the green and yellow shirt.”

Finally, I promised to explain some technical camera terms. Here are some of the general questions you might ask about your wireless hidden camera:

• What is a Wireless Camera? A wireless camera consists of a camera with a transmitter attached to it and a receiver which connects to a VCR or a TV.

• What is “Plug and Play”? Plug and Play is the easy way to install your wireless surveillance camera system. Just connect the power supply (either AC for wall power or the battery pack) to your camera. Place the object containing the camera to show what you want to review. Connect the receiver to your TV or VCR using the red and yellow RCA cable from the receiver. You are now set up.

• What is a Transmitter? A transmitter is a device that converts video signals into radio frequency signals and transmits them as radio waves.

• What is a Receiver? A receiver is an electronic device that receives radio signals from a transmitter and decodes the signal for use as pictures on your VCR or TV.

• What is “Lux”? Lux is a method of measuring a camera’s sensitivity to light, i.e. it is the amount of light the camera needs to provide an image. The lower the number, the less light the camera needs to reproduce a clear image. A Black and White camera usually has a lower lux than a color camera. It will hold an image longer than a color camera. For example, a B/W camera with a .05 lux will be better in low light than a color camera with a .5 lux.

• What is the meaning of “camera resolution” for security cameras? Camera resolution is a measure of the clearness of a security camera. It’s determined by the number of horizontal video lines that the camera must have to reproduce the correct image. The higher the resolution number, the sharper the image.

• What is a Monitor? A monitor is what you use to view your camera image. The monitor could be a TV, CCTV (closed circuit TV) or even your computer screen.

• What is “Line of Sight”? Line of Sight means that the video signal travels from the transmitter in your camera to a dedicated receiver (e.g. VCR or TV) placed a certain distance away with no obstructions or interference between the two. The signal can go through walls and floors. Low Power Cameras usually have a line of sight of 700 feet. However, you can upgrade to a High Power Camera which has a line of sight of 3,500 feet.

So there you have it — you don’t have to be a camera buff to install or operate your wireless hidden camera. Just plug and play!

Don’t Become the Next Crime Statistic! A wireless hidden camera will show you

what’s REALLY happening in your home or business.

The Wonders of Modernized Cordless Speakers

David H. Urmann asked:


Cordless Speakers have granted us the technological convenience of being able to use and bring our MP3, iPods and other gadgets that need speakers in order to showcase a sound system which a lot of people can hear.

Cordless Speakers have granted us the technological convenience of being able to use and bring our MP3, iPods and other gadgets that need speakers in order to showcase a sound system which a lot of people can hear. Gone are days when you need to have an electric socket so that these speakers can work. These days, even these speakers are rechargeable. Most even come packaged in a small, lightweight appearance.

In fact, cordless speakers are one of the wireless systems that we enjoy whenever we listen to the music on the radio, watch movies on a CD or DVD player, as well as in watching our favorite shows on TV. Normal speakers need a speaker cable. However, since the advent of technology, some speakers that are out in the market do not rely on cables anymore.

Cordless speakers accept an audio signal by using radio wave equipment. These speakers run through a transmitter that sits on to produce audio signal. Cordless speakers also have an amplifier towards the boost output. They need battery power and power adapter to plug into the AC power outlet. The average sound of cordless speakers can actually transmit about three hundred twenty feet outdoors and approximately one hundred to one hundred thirty feet indoors, across ceilings and walls. Cordless speakers are commonly modest in sound and size. Hence, the audio boost from this speaker is great because of its amplifier situated inside each speaker. The amplifier needs batteries or an electric output in order to support its function.

A disadvantage that we can only think is that if your cordless speaker needs battery, then this can add up to your expenses and they can block or interfere with other electronic devices around the house.

Hence, with this so-called radio wave technology, where in, signals from the audio source can be detected by the small receivers located within the speakers, they can either augment a wired speaker’s music or work independently on its own.

Hence, this can be an advantage for people who want their music, radio or audio files played anywhere in the house and even while they do their work or chores.

Listed below are the common types and brands of Cordless Speakers.

§ High-Frequency Cordless Speaker: This type of cordless speaker has a digital high-noise sound. This cordless speaker is powered by batteries and main adaptors. Its can also be used for personal computers, MP3 players, portable DVD players and any audio device on the planet. The speakers have 3×3.5 watts.

§ Lexibook Remote Cordless Speaker System: This speaker is compatible with a television, Hi-Fi or radio device. It works even in a range of one hundred meters. Lexibook cordless speakers are able to connect to any device that needs sound by using AA batteries, an adaptor socket and a Bluetooth device. The average price of this speaker is only $ 49.99 US dollars.

§ Yamaha Cordless Speakers: This Bluetooth portable speaker is lightweight and attractive. The speaker has a bass for those who want a sound that is in low to mid volume frequency only. It also delivers one hundred seventy five meters worth of clear sound.

Hence, a good example of this type would be the new Yamaha NX-B02, which is explicit in its quality and specifications. It has a Bluetooth device incorporated in it. Aside from this, it is lightweight and comes in a sleek design. It is also quite expensive, with a selling retail price of $199. Plus, it has an impressive evolution of last year’s NX-A01.

Moreover, this speaker is only 3.25 inches wide and extends up to 6.75 inches high. It is featured in black, white and red colours, along wit the fact that it has no Audio- Video cables attached to it. It is mainly powered by its Bluetooth connectivity and battery powered with four AA’s.

Thus, the NX-B02 is twice the size of the previous NX-A01 but the sound is less prone to distortion unlike the previous NX-A01. Although, the quality of its sound is not designed like a full blast home stereo, it is an excellent choice for a quiet space in the office, your bedroom or even the kitchen.

It also has four buttons located at its uppermost portion, which acts as its control power, two volume controls and Bluetooth activation switch. The right and left sides reveal a titanium cone driver that is about 1.75 inches and having an actual bass port similar to its predecessor, the previous NX-A01. At its back portion, you can make out the discreet connections for the power supply and 3.5 mm stereo input, however, if you would rather power it with batteries or a Bluetooth device, these connections are unnecessary.

Connecting the Yamaha NX-B02 with Bluetooth connectivity is very easy. You can accomplish this by putting the speaker into its Bluetooth discovery mode and hold the Bluetooth button down until the green LED light turns blue. Once connected, you will have no problem in synchronizing your laptop or cellular phones in order to recognize and hook up with the NX-B02.

The only problem with this gadget is that it does not have the capability connect through a solid wall from the audio source. However, it can reach a length of up to 30 feet without hiccups on its audio. Plus, this can be done without any interference such as a solid wall or any other audio device.

Even if this is quite expensive, this device is definitely worth it, due to vast difference it possesses as compared to the cheaper speakers. This would pertain to the quality of sound it features, along with its unequivocal design and Bluetooth connectivity or battery supported energy source.
