Bug Sweeping Services in Tamil Nadu

Tamil Nadu publishes more about its own policing than most states do, which works in your favour on the day something is found: the structure, the station numbers and the helpline list are all set out in the state's annual policy note, so it is usually possible to establish who takes a complaint before you make it. The sweep itself does not change from place to place. It combines radio-frequency analysis for anything transmitting, a non-linear junction detector that picks up electronics left switched off, optical and thermal checks, and a physical inspection of the places a device can be concealed. What this page adds is the layer around that work.

Nine commissionerates, and in eight of them the city and the district are different forces

Tamil Nadu is policed as nine commissionerates alongside thirty seven police districts, with two railway police districts on top and two hundred and seventy seven sub-divisions beneath. The commissionerates are Greater Chennai, Tambaram, Avadi, Tiruchirappalli, Coimbatore, Salem, Madurai, Tirunelveli and Tiruppur. If your address is not inside one of those nine, it sits in a police district under a superintendent, and the chain of command above your station officer is a different one.

The detail that costs people a day is this: in eight of those nine cities, the city force and the surrounding district are separate, each with its own head. Coimbatore city and Coimbatore district are not the same force. Only Chennai is policed as a single unit, and even there the metropolitan area splits three ways, because Tambaram and Avadi were carved out of the old Greater Chennai area and now stand on their own. Tiruppur is its own commissionerate rather than part of Coimbatore, which surprises people who think of the two cities as one industrial belt. Railway premises anywhere in the state belong to a railway police district rather than the local force, so an incident on a platform is not a matter for the city police outside.

Cyber coverage is unusually deep. The policy note lists fifty four cyber crime police stations, made up of one for each police district, one for each commissionerate, three specialised stations attached to the wings handling crimes against women and children, economic offences and the crime branch, and four zonal stations inside Chennai city. The State Cyber Crime Investigation Centre sits at the Cyber Crime Wing headquarters in Chennai and takes cases where jurisdiction cannot be established, which is often exactly the position you are in when a recording surfaces online and nobody can say where it was made.

An online complaint here is not an FIR, and the women's helpline is 1091

Start with the number, because this one changed recently. Tamil Nadu notified 1091 as the line for the Singappen Special Task Force, launched across the state on 9 June 2026 and integrated with the 112 emergency system, with seventy field units operating statewide. It is the same 1091 that the state's helpline list has long carried as the women's helpline, now with that force behind it. Any guidance written before the middle of 2026 will not mention the change, and anything telling you 1091 is a Chennai arrangement is wrong.

The number that does not apply here is 181. Several states use it as their women's helpline. In Tamil Nadu it does not appear on the police emergency list at all, because it belongs to social welfare rather than the police. The list the state actually publishes runs 100 for the control room, 112 for emergencies, 1091 for women, 1098 for children, 1930 for cyber financial fraud, 103 for traffic violations, 108 for ambulance, 1093 for coastal security, 1512 for the railway police, 10581 for prohibition and drug matters, 1800 180 5522 for anti-ragging and 94999 57575 for the senior citizens line.

Then the part that catches most people. You can register a complaint online through the state citizen services portal, check its status and view FIR details, but the state's own service list treats a registered online complaint, a community service register entry and an FIR as three separate things. A community service register entry is what a non-cognizable matter produces, and it is not an FIR. Voyeurism under the Bharatiya Nyaya Sanhita is cognizable, so a covert recording complaint is not something you finish from a laptop: it is made at the police station, and since February 2026 it is registered on the upgraded records system now used in every station in the state.

There is a real camera duty here, and a hostel licence that says nothing about cameras

Two separate things get run together constantly, and the difference matters. The first is a genuine statutory duty. Since January 2025, an amendment to the state's harassment law has required whoever is in charge of an educational institution, hostel, place of worship, cinema, hotel, restaurant, hospital, mall or any other precinct to take steps including installing cameras to prevent harassment of a woman within that precinct, and, once a complaint is made, to inform the police within twenty four hours. The fine for breach was raised to fifty thousand rupees. That catch-all phrase, any other precinct, is broad enough to reach lodges, paying guest accommodation and offices.

What the duty does not do is set a standard. It prescribes no retention period, no resolution, no placement and no coverage, and no rules have been made under it, so there is no camera specification anywhere in Tamil Nadu law. It is a duty to take steps, enforced through a fine, not a technical standard you can hold a hotel to. Its practical value to you is the second limb rather than the first: if you report a device and the premises stall, that twenty four hour reporting duty is a lever.

The second thing is hostel licensing, and it is narrower than people assume. The Tamil Nadu Hostels and Homes for Women and Children (Regulation) Act 2014 covers buildings providing accommodation for women or children. It is not a hotels law. The licence comes from the district Collector, not the police, and an amendment in May 2025 moved applications online and extended the licence from three years to ten, at a fee of ten thousand rupees. Cameras survive in that regime only as a self-declared line on a security annexure, asking how many there are and where, alongside a visitor logbook and an emergency exit plan. The licence conditions themselves do not mention cameras at all. So a licensed hostel may have none, and one that does has chosen their positions itself. Neither tells you anything about a device hidden inside a room.

We found no advisory from Tamil Nadu Police specifically about hidden or spy cameras in hotels, hostels, trial rooms or washrooms. Where a state has issued one we say so. Here there is none to point you at.
