Unless they don’t have Night Vision, then IR scanning is of no help. Using IR scanning, Lens Detection and RF detection together gives you a great chance at finding hidden cameras. This is specifically designed to find concealed cameras that use IR for Night Vision. Some Camera Detectors have IR scanning, or Infra Red scanning. This tells you to have a closer look at the item that may have a concealed lens. When you face an area with a hidden camera, you will see it reflect back and sparkle. Lens detection, or lens scanning is a red light that emanates from the Camera Detector and you watch via a special lens in the device. We have some blog articles on detection available in our blog section. Camera Detectors simply act as a radio receiver across millions of frequencies and when they detect a signal, they notify you. How Does a Camera Detector Workĭespite the price and complexity of Camera Detectors, the theory is quite simple. So basically RF is an active signal as a device pushes information into the environment via radio waves. RF EMR is non-ionising radiation, meaning that it has insufficient energy to break chemical bonds or remove electrons (ionisation). RF EMR lies in the frequency range between 100 kilohertz (kHz) to 300 gigahertz (GHz). Radio frequency (RF) electromagnetic radiation (EMR) is the transfer of energy by radio waves. With the many different frequencies used by the Phone Networks, some are better than others at different frequencies. Most Camera Detectors that detect RF will pick up Phones, Towers, WIFI, Bluetooth, GPS Trackers and RF Listening Devices. A lot of Camera Detection Equipment also have a sensitivity adjustment so if you are picking up too many signals you can just reduce sensitivity. We have picked up WIFI devices over 50 meters away with the Pro Series. This differs hugely between models, with some cheaper units just 30cm. The detection range is how far the Camera Detectors can pick up the signal. If you are looking for VHF/FM signals, roughly between 80MHz and 120MHz, Bluetooth around the 2.4GHz, WIFI either 2.4GHz or 5GHz and for mobile towers there is quite a list. Generally we look for things out of place, like a clock with WIFI, a double adapter with RF signal, and of course finger prints in places they shouldn’t be. You can learn more about the Frequency Spectrum used in Australia below. The more expensive Camera Detectors also filter out a lot of the garbage background signals leaving you with a clean detection. This is super beneficial as you can see if it is a mobile tower, a WIFI device or a Bluetooth device etc. ![]() Once you get into a higher range of Camera Detectors then you will start being able to see what frequency is detected as they display it on a screen. Since most action happens under 6GHz, a 6GHz Camera Detector covers most of the common surveillance equipment used in Australia. Some detectors can detect up to 14GHz, and some 6GHz, and some just a couple. Most start at close to zero but it’s how high they go that makes the difference. Remember, although the professional units are better, a cheap unit is better than no protection at all.Įach Camera Detector has a range of detectable frequencies. The best solution is to have one of each, or a unit that handles both. RF detectors are a little harder, but also detect listening devices and GPS, so a lot of people prefer them. ![]() ![]() Lens detectors are great and simple to use, just look through the lens and activate the lights, you will soon see the sparkle of any covert camera. RF detection which looks for a signal from a wireless or WIFI camera and lens detection. Using Camera Detectorsĭetectors are split into two basic categories. It’s these nefarious activities that detection equipment can help you overcome.įor under $100 you can have a key chain detection so you can quickly check out the area you will be in. Whilst most people purchase hidden cameras or spy cameras for home security, some don’t. In fact, it’s quite common to see instances of hidden cameras via the media. It’s all too common now with places like AirBNB and other share accommodation, where people feel unsafe. Camera Detectors are now a requirement if you want to travel, particularly if you have a family to protect.
