Try an infrared camera check and understand what it can miss.
Some iPhone cameras can show light from an infrared emitter. ClearRoom's optional check helps you try the selected camera and record a short sweep, while explaining why the result is only one clue.
Test the selected camera first
The guided check starts with the front camera, which can make infrared easier to see on some iPhones. A rear-camera option is available. Use the optional TV-remote test to see how the selected camera responds.
Seeing a remote's light does not establish sensitivity at room distance or to every infrared wavelength. Many cameras emit no infrared at all. A successful test is a way to understand the selected phone camera, not a guarantee about the inspection.
Sweep, then examine the recording
For a front-camera sweep, point the screen and lens toward the area you are inspecting. ClearRoom uses a countdown, dim screen and start/end vibrations so you can record without watching the display. The silent clip lasts twelve seconds.
Turn the screen back toward you to pause, scrub and enlarge individual frames. Ordinary devices can emit infrared; a bright point does not identify a camera. Clips remain on the phone and are deleted when you leave or background the check, unless you explicitly export a copy.
Before you finish
- Try the remote test with the camera you will use.
- Follow the illustrated phone orientation during the sweep.
- Review frames without treating each point of light as a camera.
Questions before you start
Does a negative infrared check rule out a camera?
No. Many cameras do not emit infrared and phone camera sensitivity varies.
Is sound recorded during the sweep?
No. The short inspection clip is silent and ClearRoom does not request microphone access.
