The JMDHKK / K68+ does have the longest charging time for 3+hours and is less portable than the other detectors on our list. It does have a handy light on the end as well. Additionally, the detachable magnetic probe adds to the device's practicality, allowing users to remove it when not needed, it is rather long and can become quite clumsy. Magnetic Field Detection works to help find and locate magnetic GPS trackers (both the working ones and those on standby). Particularly appreciated by individuals with hearing difficulties or in situations demanding discretion, the vibrate option replaces the piercing beep, which is, on this device, an optional feature rather than a default which I appreciated. On the LED display, it is easy to see the RSS (received signal strength), battery percentage, and alert mode switched on.Ī notable feature is the 'AI' function, activated by the right button, employing a pulse-based approach to streamline scanning, although it still needed me, the user, to figure out false positives. The simulated analog dial conveniently displays the strength of the detected signal, and the top dial let me adjust sensitivity while narrowing down a focus on a potential threat. The Sherry model is easier to find in the USA, while the KMDHKK edition is easily found in the UK.Įquipped with a built-in infrared detector, this hidden camera detector primarily relies on its robust RF sweep capability. Be warned, though, that it's known by a number of names. The K68 is a powerful hidden camera detector. I enjoyed the hidden telescoping antenna, think inspector gadget vibes which was a small but fun thing to use. The C10 Pro has the smallest battery of those on test and didn't seem to last more than a day or so but only has a 2hr charging time which should be enough to get you going.

Additionally, it offers an LED signal strength meter with nine levels for “precise” signal finding. There are two sensitivity levels, and three detection Modes (visual, vibration, and mixed), this device provides comprehensive coverage.

It excels in detecting both transmitting and non-transmitting cameras, regardless of their operational status whether on or off (with mixed success), wired or wireless, and in active or inactive states.įeaturing a camera finder which like the others you have to look through but only flashes without a constant IR bean option. Despite its smaller size (about the size of a business card) the C10 Pro is a pretty sophisticated hidden device detector, capable of identifying RF transmitters across an extensive frequency range spanning from 1 MHz to 10 GHz. It can detect an RF signal with a power range of -74dBm to 18dBm and convert it to a DC voltage output.While testing the C10 Pro it become apparent that it had a wider range of detection than the others I tested. The personal RF detector detects RF signal power in the frequency range of 1MHZ to 600MHZ. Higher-order quadrature amplitude modulation (QAM) signals, for example, have high crest factors (e.g.,16QAM, 64QAM, and 256QAM). The crest factor is the signal's peak to RMS value. The RMS portable rf detector is generally preferable in applications where the signal has a high crest or widely varying crest factor. Because of the fast response times available for pulsed RF signals, the log type is also preferred. The RF log detector is useful for most general power measurement and control applications. The most important deciding factor in the type of RF sensor to use is the RF signal to be measured. The RMS detector generates a dc output proportional to the signal's RMS value. The log detector converts the input RF power into a dc voltage proportional to the log of the input, resulting in an output that is directly proportional to decibels. There are two fundamental types: logarithmic and RMS.

Types of RF Detectors: General Criteria for Selecting an RF Detector Type to Use The diode RF detector converts direct current to direct current, which is then relayed to a power meter, which measures and scales the DC voltage to produce a power readout. High-frequency semiconductor diodes are used in diode-based RF power sensors to detect the RF voltage developed across a terminating load resistor. Another popular application in high-power RF amplifiers is voltage standing-wave ratio (VSWR) measurement and control. RF detectors are primarily used in wireless systems to measure and control RF power. An RF detector monitors or samples an RF circuit's output and generates a direct current output voltage proportional to power at that point.
