With spy cameras now smaller than a button and available online for under $50, hidden surveillance is a real concern.
Bug sweeps remain one of our most common enquiries, with clients turning to us when something feels “off” but they can’t pinpoint why – and they’re almost always right to trust their instincts. As licensed private investigators regularly conducting bug sweeps across the GTA, here are the five most common hiding spots we encounter.
1. Smoke Detectors
Why they’re used:
- Ceiling-mounted = full room view
- Hard to reach = rarely inspected
- Expected in every room
- Constant power source
🚩 How to spot them: Look for unusual lights, irregular wiring, or holes in the grillwork. Remove the cover carefully (electricity off) and check for lenses or devices inside.
2. USB Chargers & Outlets
Why they’re used:
- Always plugged in = unlimited battery
- Blend perfectly into any room
- Easy to aim at beds or desks
- People use them without thinking
🚩 Red flags:
- Chargers larger or heavier than normal
- Small holes or irregularities in outlets
- Doesn’t actually charge devices properly
- Positioned facing private areas
3. Everyday Objects
Common disguises:
- Alarm clocks (camera in display)
- Picture frames (lens in frame edge)
- Pens and USB drives
- Bluetooth speakers
- Computer mice
Quick check: Use a flashlight in a dark room and scan slowly. Camera lenses will reflect light – look for tiny glints.
4. Air Fresheners 🚨
This is the one that surprises everyone.
Why they’re perfect for hiding cameras:
- In EVERY room (bathrooms, bedrooms, offices)
- Positioned at perfect height
- Plugged in constantly = never dies
- Nobody inspects or touches them closely
- Available as “spy camera air fresheners” online
🚩 What to check:
- Unusually positioned air fresheners
- Heavier than expected
- Small holes or lens-like dots
- New items that appeared after you arrived
5. Decorative Items
Common hiding spots:
- Stuffed animals (cameras in eyes)
- Fake plants
- Tissue boxes
- Decorative hooks
🚩 Red flags:
- Items that weren’t yours appearing in your space
- Gifts from people who make you uncomfortable
- Objects with direct views of beds or bathrooms
