FAQ

Hidden-camera inspection: common questions

Price, timing, equipment and privacy: the questions people ask most before booking.

How much does an inspection cost?

The early-bird price is NT$1,000 for 2 rooms (one living space and one bathroom). Each extra room adds NT$500. Standard prices are NT$1,500 for 2 rooms, NT$2,500 for 4 rooms and NT$4,500 for 6 rooms.

What counts as one room?

Each separate room counts as one. Bedrooms, living rooms, bathrooms and walk-in closets each count as one room.

How long does it take?

About 60 minutes for 2 rooms, 90 to 120 minutes for 4 rooms and 150 to 180 minutes for 6 rooms. Each extra room adds about 25 to 35 minutes.

What equipment do you use?

For optics we use the GL-i08 red-and-green lens detector, which finds lens reflections. For signals we use the GL-i23, which scans wireless signals from 50MHz to 6GHz and also detects magnets. Both are made in Taiwan.

Which areas do you cover?

We currently serve Taipei, New Taipei and Taichung. There is no travel fee within 10 km one way. Longer distances add NT$200 to NT$1,000, and trips over 100 km are quoted separately.

Can you check the hotel room I am staying in?

Yes. Hotel-room checks cost the same as home inspections, plus a travel fee by distance. Book before 18:00 and we arrive the next day. We only do non-destructive visual checks and instrument scans, and we never dismantle hotel fixtures.

Is the inspection confidential?

Every inspection comes with a signed NDA. Your home never appears in any promotion without your consent. You may decline photo consent and the price stays the same.

What do I receive afterwards?

We explain the result of each room on site. The full written report arrives as a PDF within 48 hours. You can ask follow-up questions free of charge for 7 days.

What can the instruments not detect?

The result reflects the rooms we checked at the time of the inspection. Instruments cannot see inside sealed walls, or devices that are powered off and not transmitting. The report lists every location we checked.

What happens if you find a device?

We do not touch, remove or move it. We photograph its location, record the readings and time, and both sides sign the record. What happens next is your decision.

Who can book, and do I need to be there?

We only inspect spaces you have the right to use, such as your own home or rental. The client must be 18 or older and present throughout.

Can I cancel or reschedule?

Free before 18:00 the day before. Same-day cancellation costs NT$500 to cover travel.

How do I book?
