The Ultimate Spy Cell Phone

Perhaps the most advanced portable bug on the market today is the Spy Matrix Spy Phone. This spy cell phone looks just like a regular phone, and it works just like a regular cell phone. The only difference is that is also a bug. This is the ultimate in listening devices. It is the best way to keep track of teenagers or significant others who show signs of straying. And, with a little ingenuity, you can even use this spy cell phone to perform surveillance on acquaintances and strangers.
The spy cell phone is especially helpful when you want to keep track of family members. This is because you can pass it off as a new phone for the family’s new cell phone plan. It is perfect. Give it to teenagers and you can go wherever they go. This Spy Matrix Spy Phone is equipped with a GPS tracker and a special microphone that picks up noises and conversation in its general vicinity. Not only that, but can also allow you to listen in to both ends of the conversation. You can know whether you teen are where she or he is supposed to be, and you can find out, from listening to what is going on in the room, whether there really is a study group.
A secret phone number allow you to activate the spy cell phone without the subject knowing that you have done so. You call the secret number (there is a second real number for regular calling purposes) and the phone quietly turns on and begins giving you access. You can “forget” it in a room or leave it to “charge” and hear what others are saying. This is a device that is also useful when performing professional surveillance for clients. No matter what you want to use the phone for, the spy cell phone is a device that few people would suspect as being a bug — especially since it works just like a normal cell phone in all respects.
Stop wondering what is really going on and find out for sure. When you have the Spy Matrix Spy Phone you do not just have any phone. You have a real, top of the line spy cell phone.

Prevent Phone Monitoring

If you are using an analog cordless or cellular telephone, someone is listening to your conversations!
You'll notice I did not say someone might be listening to your telephone conversations, or there is a possibility that your telephone conversations can be overheard. Simply put, your telephone conversations are being monitored! Radio hobbyists, with their scanners being used as spy equipment, have the capability to listen to telephone conversations and we must assume that a small percentage do from time to time.
Beyond these hobbyists, however, is an underground culture of scanner users who make specific efforts to monitor telephone conversations. This underground culture ranges from individuals wanting nothing more than to satisfy their personal curiosity, to news reporters lookng for leads, to private eyes gathering information for a case, to criminals listening for credit cards numbers, SSN's, or other information to be used in the furtherance of a crime. Beyond this, various law enforcement and security agencies may monitor telephones for their own purposes.
But wait, you say--it's illegal to monitor telephone conversations. It's even illegal for the police to do so without a warrant. True, it's illegal to monitor telephone conversations, but do you really think that noone's listening? A law is nothing more than words and, in and of itself, does nothing to prevent that which it proscribes. The chance of getting caught doing phone monitoring are almost nil, and when have you heard of anyone being prosecuted for monitoring a cordless phone?
HOW TO PREVENT IT
One way to prevent monitoring of your telephone conversations is through the use of digital spread spectrum technology. To understand this, we first need to be aware that telephones are either analog or digital. Analog telephones are nothing more than radio transmitters sending signals between the telephone and the cell site in the case of cellular phones and between the handset and the base plugged in the wall socket in the case of cordless phones.
Any radio scanner can be programmed to receive the cordless telephone frequencies. Newer scanners have the cellular telephone frequencies block, but these frequencies can be unblocked by anyone with a basic knowledge of radio electronics. Digital telephones are also radio transmitters, but a digital signal is unintelligible when heard on an analog receiver. Of course, a digital receiver would receive a digital telephone signal were it programmed to the appropriate frequency. However, here is where spread spectrum technology comes in.
Spread spectrum was first used during World War II as a method to prevent torpedos being jammed en route to their target.
Digital spread spectrum uses a signal spread over a number of frequencies. These signals are difficult to intercept and demodulate and are resistant to jamming or interference. This provides for a clearer and cleaner telephone signal, as well as preventing monitoring of the signal itself. It is also worth noting that cordless telephones are now available with an operating frequency of 2.4 GHz. Since most scanners do not receive into the gigahertz range, this gives additional protection against interception and phone monitoring of your telephone signal as it is transmitted between the handset and the base.
