The people doing the work
Credentials you can check, not claims you have to take on trust
Counter-surveillance is an industry where anyone can call themselves an expert, because the work happens privately and the results are rarely discussed. That makes verifiable credentials worth more than adjectives.
Our founder, Hardesh Bhardwaj, has practised since 2013 and was named Investigator of the Year 2026 by the World Association of Detectives, an international body whose annual conference has run for more than a century. The award photographs, the signed certificates and the company registration are all published in full on his credentials page.

Equipment We Use
The Instruments Used in a Sweep
A sweep combines several instrument classes, because no single one is sufficient: spectrum analysis for devices that transmit, non-linear junction detection for electronics that are switched off, and thermal and optical checks.

REI OSCOR Green 24 GHz Spectrum Analyzer
Scans the entire radio spectrum from 10 kHz to 24 GHz, detecting all active frequencies. Compares indoor vs outdoor reference scans to pinpoint hidden RF transmitters inside walls, furniture, power adapters, and more.

REI ORION 2.4 Non-Linear Junction Detector
Detects electronic components as tiny as a grain of rice — even when the device is completely powered off. Vital for locating eavesdropping devices hidden inside furniture, light fixtures, or ordinary household items.

Handheld Non-Linear Junction Detector (NLJD)
Identifies all kinds of electronics — active, inactive, or powered down. Detects mobile phones, tracking devices, hidden microphones, covert cameras, digital recorders, SIM cards, and any electronic circuit or microchip.

REI ANDRE Deluxe Near-Field Detection Receiver
Portable broadband receiver detecting RF, infrared, visible light, carrier current, and various transmitters from 10 kHz to 6 GHz. Ideal for non-alerting initial sweeps as a companion to spectrum analyzers.

ORIUS® Wi-Fi Hunter
Detects, pinpoints, and investigates any device transmitting over Wi-Fi. Identifies hidden networks, de-authenticates rogue devices, and monitors for suspicious activity, new or duplicate access points.

FLIR Infrared Thermal Camera
Detects active heat signatures from bugging devices hidden inside walls, ceilings, floors, furniture, light fixtures, pillows, stuffed toys, or air vents — regardless of location.

VPC-62 Video Pole Camera
Visually inspects above drop ceilings, behind heavy furniture, around corners, and other concealed spots in low-light conditions. Checks for hidden cameras and traces wires connected to covert devices.

BlueSleuth™ Bluetooth Detector
Detects and tracks hidden Bluetooth and BLE devices with a directional antenna providing real-time RSSI readings. Locates covert Bluetooth bugs, microphones, earpieces, and unauthorized wireless devices.

Video Borescope
Visually inspects inside air vents, vehicle dashboards, behind furniture, and above cabinets. An essential tool for any thorough bug sweep — used to detect hidden microphones or covert cameras in hard-to-reach places.

Hidden Camera Detector
Engineered to uncover concealed cameras including ultra-small pinhole types — powered on or off. Uses reverse reflection technology to spot lenses even behind tinted glass, detectable up to 60 feet away.
GPS Tracker / Cell Phone Detector (WolfHound Pro)
Locates active hidden cell phones, GSM bugs, and GPS tracking devices. Pinpoints exact location whether in standby, on calls, sending data, or transmitting live GPS signals.

Countermeasure Amplifier
High-gain audio amplifier connected to telephone lines, LAN/server networks, AC power circuits, and alarm wiring to uncover hidden eavesdropping devices exploiting these connections.

REI TALAN Telephone & Line Analyzer
Thorough sweep and analysis of telephone lines in residential and business environments. Inspects copper wire, digital, and VoIP systems for taps. Analyzes IP packet traffic for unauthorized interceptions.
Note: Our technician will choose the appropriate detection equipment for each sweep based on your unique concerns and assessed threat level. Each sweep is tailored for maximum effectiveness.

Why Choose Us
Why People Come to a Specialist
People come to us when the stakes are high enough that they want the question settled properly. A thorough sweep takes more than a consumer detector bought online: it means agreeing what is in scope, working through it with several different instrument classes, and being told plainly what was found and what could not be established.
- 13 years of TSCM and investigative practice
- 500+ successful sweeps across India
- Client identities never disclosed, in any circumstances
- A written account of what was examined and what was found
Case and sweep totals are the firm's own reported figures, as at October 2026.
Where we work
36 cities and 15 states, covered properly
The sweep does not change from one city to the next. What changes is everything that happens afterwards: which police force covers your address, whether an online form produces a complaint or an actual FIR, and which helpline the state publishes. Each of our location pages sets that out for the place it covers, checked against official sources rather than copied from other sites.
Not seeing your city?
Sweeps are arranged well beyond the cities listed above, including the district towns named on each state guide. A page exists where we have local detail worth publishing, which is not a limit on where we travel.
Published guidance
What we know, written down
We publish the detail rather than keeping it back: how devices are actually concealed, what the law says about covert recording, and what to do in the first hour after finding something. Read it before you call anyone, including us.
How to Detect Hidden Cameras: What Works, What Does Not, and the Law in India
Most advice on finding hidden cameras oversells the phone in your hand and skips the law entirely. This guide sets out what each check can and cannot establish, where cameras have actually been found in India, and the reporting route, including the helpline that is the wrong one to call.

Clicks on the line, a hot phone, flickering lights: the classic warnings are repeated on almost every page about this, and most of them have ordinary technical explanations. This guide separates the folklore from the two indicators that genuinely change the odds.
