How does an RF detector work?

RF deviceWhen someone turns on this device, there is display of a signal with LED lights. It can be supplemented with an audible alert to provide a more accurate operation. The visual or audible signal intensifies or weakens as the user moves closer to or further away from a device emitting RF signals.

Professionals using an RF detector need most wireless network devices to be turned off. The leading wireless networks that can provide a false signal on the RF detector device are as follows.

  • Devices with wi-fi networks
  • Devices with Bluetooth turned on (1)
  • Cordless phones with a call
  • Cell phone wireless networks

Where can an RF detector be used?

It is best to have your own RF detector for use in all suspicious places in your home. An RF detector works better as it gets closer and closer to the spy camera. This tool can be used anywhere.
