They show you the spectrum.
We show you the threat.

A new generation of technical surveillance countermeasures, built by the people who build the radios.

The reality

A threat surface that never stops widening.

The covert transmitter no longer hides in a simple analogue bug. It rides the same 2.4 and 5 GHz traffic an office runs on, speaks Bluetooth LE, Zigbee, Thread and Matter, beacons over sub-GHz LoRa, and slips through 5G and store-and-forward devices that transmit only in short bursts. Finding it means seeing every protocol on every band – and triaging faster than the threat can move.

And a general-purpose spectrum analyser was never designed for that job.

The category shift

Not a laboratory. An answer.

Everyone else hands the operator a laboratory instrument and asks them to interpret it. We hand them the answer – what it is, where it is, and why it matters – in an instrument anyone trained for a day can use.

General-purpose analyser

Shows you the spectrum

Needs a trained RF operator, priced like a laboratory, one box over-built for any one job – and after seconds of interpretation, a guess.

Purpose built TSCM Solution

Shows you identity

Usable by anyone trained for a day, priced for the mission it does, complete for its job – and in seconds, a classified, located, scored answer.

Same breadth of coverage. Opposite philosophy.

The range

One mission. One System. No compromise.

Instead of one over-stretched box, a menu of dedicated Equipment – each complete for its job, each usable, each affordable for what it does.

Sanjay Threat Analyzer

Sees Wi-Fi, BLE, Zigbee, Thread, Matter, LoRa and DECT – every device on every supported protocol, classified and scored in seconds.

Detection

Contraband Phone & IMSI-Catcher

Finds the phone that shouldn’t be in the room, and rogue base stations impersonating legitimate networks.

Detection

Camera, Satellite & LoRa

Covert cameras and smart-glasses, satellite phones, and long-range LoRa beacons that hide beneath conventional sweeps.

Authorised users only

Where lawfully authorised - active response.

Beyond detection, active-response instruments can take the threat off the air. Supplied only to authorised users and operated within applicable spectrum and legal authorisations. Shyam TSCM instruments are intended for authorised Indian Government-approved organisations and for export in line with applicable controls.
