Behind the painting
A guest found a camera halfway behind a painting — the lens peeking out, discovered because they heard it clicking after getting out of the shower.

Still skeptical? Good — here’s the honest truth:
“Do these things even work?”
It’s physics, not a gimmick. Every camera has a lens, and a lens throws your red light straight back as a glint you can see with your own eyes — even cameras that are off, hard-wired, or saving to an SD card. Those are the exact ones phone apps and beep detectors physically can’t catch, because there’s no signal to find.
“I’m honestly not techy.”
There’s nothing to set up. No app, no wifi, no signal to read — just light and your eyes. One button turns it on; look through the filter and slowly scan the room — hotel, Airbnb, changing room, or office. Start with anything that has a view of the bed or bathroom.
“What if a normal reflection fools me?”
A real camera lens flares back tight and bright — and it stays lit when you shift a few inches to either side. A random shiny surface won’t. That quick two-angle check is the whole trick, and it takes about two seconds once you’ve seen it.
“Why is this $24.99 when the ‘trusted’ one is $200?”
Same optical lens-detection the $200 pro units use — without the brand name and the middlemen stacked on top. You’re paying for the physics, not the prestige. And it’s backed by a 30-day money-back guarantee, so the risk is on us.
“Won’t carrying this just make me paranoid?”
It does the opposite. It’s a one-minute habit — like checking the door’s locked — that ends the second-guessing so you can finally settle in and relax.
The Flektr device, a USB charging cable, a carabiner/lanyard clip.
Shine the ring of red LEDs around the room. Look through the red-tinted filter. Any camera lens — on, off, wired, or recording to an SD card — reflects the red light straight back at you as a bright glint. Flektr lights the lens up; your eye does the finding.
30-day full refund, no questions asked. Email support@getflektr.com with your order number. Refunds processed in 1–2 business days.

Watch a hidden lens give itself away.
No beep to interpret. No app asking you to trust it. The red dot below is a camera lens reflecting Flektr's light straight back at you.
Flektr lights the lens up; you do the spotting. Shiny objects can glint too — the two-angle check tells them apart: a real lens keeps glinting when you shift; a sparkle doesn't.

The Blind Spot
The camera was off. That's why nothing beeped.
Phone apps and "beeping" RF detectors can only find a camera that's broadcasting a signal. The cameras that get people filmed are the silent kind: off until motion wakes them, hard-wired into the wall, or saving to a memory card with no signal at all. To a wifi scanner, a camera like that simply doesn't exist — you'd scan, hear nothing, and relax in a room that wasn't clear. A false sense of security is worse than no check at all.
“RF tools won't find cameras that use SD cards to store data.” — spy-camera expert, CNBC test (Jan 2024)
The Solution
A lens can't hide from light.
Every camera — wired, wireless, off, or on — has one thing it can't function without: a lens. And a lens, by its physics, reflects light straight back at its source. It's the same reason an animal's eyes flash back at you in headlights. Flood the room with Flektr's focused red light, look through the matched filter, and any lens facing you fires back a bright red glint. You're not hunting an invisible signal anymore — you're looking at the eye of the camera itself.
This is the method counter-surveillance professionals reach for first — the trusted optical units run about $200. Flektr is that method, pocket-sized.
Get the Method — Flektr3 Simple Steps
The 1-Minute Room Check
Where you start checking — bed and bathroom sightlines first.
Light It Up
Press and hold the button. The ring of red LEDs comes on — steady beam, or strobe for brighter rooms.
Sweep the Sightlines
Look through the red filter and scan slowly: smoke detectors, alarm clocks, USB chargers, vents, shelves — anything with a view of the bed or bathroom.
Catch the Glint
A camera lens reflects the light straight back as a sharp red dot. See one? Check it from a second angle — a real lens keeps glinting; a screw or glass edge won't.

I've been checking every room for two years just by eyeballing it and never knew if I was actually safe. The first time I used Flektr I found a reflection in a smoke detector.

The apps never found anything. Neither did the beeping one I bought on Amazon. This actually shows you something. Totally different experience.

Bought it before a solo trip to Nashville. Used it in 3 Airbnbs. Nothing found (great!) but the peace of mind was 100% worth it.

I travel for work 3 weeks a month. This lives in my laptop bag now. Takes a minute and I can actually relax in my room.

My daughter goes to college out of state and I got her one too. She uses it every time she moves into a new place.

Questions? We've got answers.
Every camera has a lens, and a lens reflects light straight back toward its source. You shine Flektr's red light around the room and look through the red filter — any hidden lens glows back as a bright red dot you can see with your own eyes. No app, no beeping, no guesswork.
Yes. Because Flektr detects the lens itself — not a wireless signal — it can reveal cameras that are powered off, hard-wired, or recording locally to an SD card. Those are exactly the cameras that phone apps and RF "beep" detectors miss, because those tools can only find a camera that's actively transmitting.
None. Flektr is one button: turn it on, look through the filter, and slowly scan the room. There's nothing to download, pair, or set up.
Most cheap detectors are RF/signal detectors — they beep near anything electronic (routers, TVs, phones) and only catch cameras that are broadcasting. Flektr uses optical lens detection, the same method counter-surveillance pros reach for first, so you actually see the lens instead of chasing a beep.
A real camera lens reflects a tight, bright red glint — and it stays lit when you shift to a second angle. An ordinary shiny surface won't. That quick two-angle check is all it takes to be sure.
Flektr is backed by a 30-day money-back guarantee. If it's not for you, email support@getflektr.com with your order number for a full refund — no forms, no hassle.
Orders ship within 24–48 hours with tracking. Most US deliveries arrive in about 5–8 business days.
No — Flektr is a camera-lens finder. It reveals hidden camera lenses, not audio bugs or GPS trackers. We keep that honest so you know exactly what it does and doesn't do.
