These days it's almost impossible to walk in some public place without being caught on camera. Markets, small shops, museums or banks, all use surveillance cameras for protection. CCTV surveillance has grown significantly over the last decade and this growth doesn*t seem to stop.

However, security cameras for surveillance may not only be used in public places. You might not even expect that, but even in some private areas, like changing rooms, showers or hotel rooms, spy cameras might be waiting to catch you.

Such illegal activities are prohibited, but not everybody obeys the rules. There are many people who'll want to spy on you in private areas without even considering your rights to privacy. In such cases, a spy bug detector can help you protect yourself from being caught on hidden cameras.

Why Bug Detectors are Useful?

First, let's try to find out what a bug detector actually is. A bug detector is anti surveillance device that is used to capture various spying gadgets in the area. Bug detectors come in many shapes and sizes and functions.

Small bug detectors might be used to track audio bugs in the phones or near the phones. Larger bug trackers, measuring the size of a briefcase, can track spy cameras, audio spy equipment and have much more functions than smaller ones. Of course, such detectors cost more also.

Technologically more advanced bug detectors not only allow you to detect any bugs in the room. They can also *steal* the RF signal and display what the security camera sees. If the CCTV cameras don*t use any signal encoding, then such spy cam bug detectors will easily display you the wireless camera's view.

How a Bug Detector Works?

Let's try to briefly cover how a bug tracking tool works.

Wireless devices, like spy cameras or even computer networks, work by sending radio signals from one location to another. Such signals are called RF, which refers to *Radio Frequency*. Such devices use RF signals to communicate with the receivers. Now a bug detector simply scans the whole room or office for such radio signals and reports to you when it detects anything.

One note here. If you*re doing surveillance in your house, then turning off some wireless devices, like cell phones could be a good idea. This is just to help you better track and spot bugs or spy cameras in the room.

Frequency Range

Usually, bug detectors operate in 2GHz or 3Ghz frequency range. Now, most spy devices also operate in this range, so there are no problems spotting a bug in that range. However, some (more sophisticated) spies will change the frequency of a bug to a higher level, like 4GHz or 6GHz. Then, a common bug tracking device won*t be able to catch any frequencies, but a more advanced solution will do the job*

There are powerful bug detectors for private investigators; or the ones that police use, which can detect RF signals even up to 9GHz. They cost more, but they'll spot any bug in the room without problems.

Can Surveillance Bugs Spot Wired CCTV Cameras?

Most bug detectors are able to track almost any wireless spy device that uses RF signals. Be it a wireless mini hidden camera, a phone bug, or a blue tooth spy cam*

But, detecting hard-wired cameras was a little problem. It's simply because they don*t use radio frequency signals to transmit data between the transmitter and a receiver. Now, powerful bug tracking devices can spot even wired CCTV cameras in the area. So the main problem is simply gone with these new-era bug trackers.
