Principle of operation, how Electronic Device Detector EDD-24T works, and how it can detect video and audio spying devices:

Semiconductor Electronics are used in all modern electronics and are made using Silicon substrates. When high-frequency radio signals are transmitted directly over silicon it produces a strong second harmonic frequency of that radio signal. Other materials such as some bi-metals or oxidized metals can respond with a third harmonic signal.
The EDD-24T transmits a focused directional signal on 2.4 GHz (ISM Band Type B). It receives on 4.8GHz (Second Harmonic) and 7.2GHz (Third Harmonic).
The highly sensitive receiver will respond to any signals produced on the 2nd Harmonic by even the smallest piece of Silicon such as that used in SIM Cards, Mobile Phones, Bugging Devices, Voice Recorders, Covert Video cameras, etc. Importantly those devices do not have to be in use, on standby, or even have any power connected to them to be detected.
The 3rd Harmonic receiver acts as a valuable confirmation for signals that may be ambiguous or are not a threat such as those in oxidized metals, bi-metals, etc.

Probability Indicator

To allow even an inexperienced user to make a quick assessment of a detected signal the EDD-24T uses an intelligent algorithm to analyze the detected signals from both the 2nd and 3rd Harmonic Receivers and evaluate the probability of material being detected as ‘Silicon’ or ‘Metal’.

Audio Confirmation and how to tell if there is a spying device:

The EDD-24T Can provide audio confirmation of detected signals in two ways, through the internal loudspeaker or earphones.
 
TONE Mode can be used to provide an audible tone of a detected signal on the 2nd Harmonic only. This enables the user to search without looking at the display screen. The TONE changes in pitch according to the strength of the detected signal.
DEMOD Mode can be used to listen to an actual demodulated signal of the 2nd Harmonic Receiver. When no signals are detected a random audible ‘Click’ sound will be heard. In some cases when Silicon is detected the click level will reduce or become completely silent.
The Electronic Device Detector -24T is genuinely portable for handheld use and weighs just 750g. The Electronic Device Detector is encased in a machined aluminum enclosure for ultimate durability with a tough plastic antenna cover. The internal Lithium Polymer battery pack gives up to 4.5 hours of use from one charge. The whole package is supplied in a compact military standard carry case for ultimate protection and portability.
The Electronic Device Detector - 24T is designed, manufactured, and tested in England to the highest technical standards.
