Download a Smartphone App Some of the best apps for detecting hidden cameras and microphones include Hidden Camera Detector Free for Android and Hidden Spy Camera Detector for Apple. Most apps scan the area using an infrared scanner and/or visible light emitters.
A hidden microphone will usually be a small, black shape that can be tucked into tiny areas. Look for a wire coming off of it, either leading to something else or working as an antenna. There may be a small hole in the center of the housing to let the microphone record more easily.
Use RF detectors:
The first things you will come across are RF detectors, as they help you scan the radio frequencies used in the transmitters associated with microphones or cameras. Get yourself a radio frequency detector and take it around the home to locate any recording devices.
With an eye towards privacy, deviceOwl helps you quickly identify these devices, providing both simple, and in-depth details about their capabilities.
Use a Radiofrequency Scanner
If you've found something that looks like a bug, or you want to search for a listening device covertly, you can purchase a radiofrequency scanner. These pick up anything broadcasting a radio signal, including bugging devices.
Microphone Access. If you see a yellow dot above the cellular signal icon while you're actively using an app on your iPhone, it means that the app is currently using the device's microphone. You'll see this show up when you're in the middle of a phone call, voice chat in an app, or while audio recording in general.

There are several signs that someone may be spying on you in your home. They can opt for physical equipment such as listening devices or hidden cameras, or they can use technology, such as spyware, to hack into your digital devices such as your phone or computer.
A Covert Listening Device is an electronic device that is concealed with the purpose eavesdropping on conversations. Covert Listening Devices are also known as wires or bugging devices or when use on telephone lines, as wire taps or intercepts.
Most spy microphones connect to the computer via a USB port to transfer their audio files. However, some devices are also able to be connected via Wi-Fi or Bluetooth. Devices that work using a SIM card obviously connect to a telephone network.
Audio jammer and acoustic noise generators
If you suspect someone is listening to your conversations, you should invest in an acoustic noise generators or voice jammers. These devices are designed to interfere with microphones' recording and listening capabilities by releasing white noise.
The short answer is yes, your smartphone is technically always listening. However, the truth is a bit more complicated. A voice-activated device has to be constantly eavesdropping so that it picks up on “wake words,” or the voice command used to activate their virtual assistant service.
According to Lifehacker, your iPhone automatically tells you when the phone or microphone is active—you just have to know where to look. When your phone is taking a video recording, a green dot will appear in the top-right corner of the screen. For audio recordings, an orange dot will be visible in the same place.
So, let's discuss the three main types of microphones for recording or amplifying vocals or instruments: dynamic microphones, condenser microphones, and ribbon microphones.
The microphone is embedded in a pinhole on your device.
For phone-type devices the microphone is at the bottom of the device. Your tablet microphone may be at the bottom of your device, in the upper-right corner on the side, or at the top. Just look for the pinhole.
Can you hear on security cameras? Users can hear what the security camera picks up if it has a microphone. IP security cameras commonly have microphones. Traditional CCTV, which uses coaxial cables to transmit data, doesn't usually have audio, because the cables can't natively transmit audio.
An application to use a listening device must be made in writing and set out the reasons for why the use of a listening device is necessary. The application must also be supported by a sworn affidavit. If the application is granted, a warrant is issued authorising the use of the device.
