The high-pitched beeping sounds you and the other person hear during a phone call are unlikely to be caused by the frequency of a hidden camera. Hidden cameras typically operate on frequencies that are not audible to the human ear, and they are designed to be discreet and undetectable.
There can be various reasons for high-pitched beeping sounds during a phone call, and it's more likely to be related to the phone or the phone service rather than a hidden camera. Here are some potential causes:
Call quality or network issues: The beeping sounds can be a result of poor call quality or network problems. Issues such as line interference, network congestion, or signal problems can introduce artifacts or distortions into the audio, including beeping sounds.
Phone or headset malfunction: Malfunctioning or faulty phones or headsets can produce unexpected sounds during calls. Internal electrical issues or problems with the microphone or speaker components can lead to the generation of beeping sounds.
Call waiting or call notification tones: Some phone systems are designed to provide call waiting or call notification tones, which can manifest as beeping sounds during a call. These tones alert the user to incoming calls or other call-related events.
Digital signaling or error indicators: Certain digital phone systems or services may have audible indicators for signaling or error conditions. These indicators can produce beeping sounds during a call to notify the user of specific events or issues.
Interference or electronic noise: External sources of interference or electronic noise can also introduce unwanted sounds into a phone call. This can be caused by nearby electronic devices, electrical wiring, or other environmental factors.
If you suspect the beeping sounds are related to a hidden camera or any other potential security concern, it's advisable to seek professional assistance. A security expert can assess your situation and help determine if there are any unauthorized devices present.
