What Is a Bug Sweep?
A bug sweep – formally known as a Technical Surveillance Countermeasures (TSCM) sweep – is a systematic physical and electronic inspection of a space designed to locate unauthorized surveillance devices. Hidden cameras, listening devices, audio transmitters, and phone taps are more accessible than ever, and most are built to stay hidden from anyone without the right equipment to find them.
Eye Spy uses professional-grade detection tools including RF spectrum analyzers and non-linear junction detectors to scan for transmitting and non-transmitting devices alike. A consumer detector from a spy shop will not find what our equipment finds.
Residential Bug Sweeps
Homes are a common target for hidden surveillance, particularly in situations involving divorce, custody disputes, or domestic conflict. Eye Spy sweeps bedrooms, living areas, home offices, and phone lines for any device that should not be there.
If something is found, we document it, identify the type, and walk you through your options – including whether law enforcement involvement is appropriate.
Office and Business Bug Sweeps
Corporate espionage is not limited to large companies. A competitor, a former employee, or a party involved in active litigation may have reason to plant a device in your conference room, executive office, or phone system. Eye Spy provides commercial TSCM sweeps for businesses of all sizes throughout Michigan.
Common settings include conference rooms, executive offices, private meeting spaces, and business phone lines.
Phone Tap Detection
A compromised phone line can expose private conversations, business strategy, or legal discussions to people who have no right to hear them. Our investigators check all accessible points at your premises for evidence of telephone taps or intercepts. The process takes several hours and requires multiple specialized pieces of equipment.
If something is found, you will know exactly what you are dealing with – and where to go from there.
Signs You May Need a Bug Sweep
Most people who call us do not wait for proof – they call because something feels off. Common indicators that a device may be present:
- Private information is being shared by someone who should not have access to it
- Unusual clicking, static, or volume changes on phone calls
- Electronics in your home or office are behaving unexpectedly
- Your space was accessed but nothing obvious was taken
- A new item appeared – a clock, a power strip, a smoke detector – that you did not put there
You do not need proof before calling. Finding out whether something is there is the whole point.

Common Questions About Bug Sweep Services in Michigan
What does a bug sweep cover?
A professional bug sweep covers a physical and electronic inspection of your space for hidden cameras, listening devices, audio transmitters, phone taps, and other unauthorized surveillance equipment. Eye Spy sweeps homes, offices, conference rooms, and businesses throughout Michigan. Vehicle and GPS tracker sweeps are handled on our vehicle bug sweeps page.
How long does a bug sweep take?
The time depends on the size of the space and the number of areas to cover. Phone tap detection alone takes several hours. A full residential or commercial sweep will take longer. Eye Spy will give you a realistic time estimate when you call to discuss your situation.
What happens if a listening device or hidden camera is found?
If a device is found, Eye Spy documents it, identifies the type, and investigates the source. You will know exactly what was found and where – and we will walk you through your options, including whether law enforcement involvement is appropriate. We maintain chain of custody on any evidence found.
Can you detect devices that are turned off or not actively transmitting?
Yes. Professional-grade tools such as non-linear junction detectors can locate electronic components even when a device is off or in a dormant state. This is one of the reasons consumer bug detectors from spy shops are unreliable – they only detect actively transmitting signals.
