Frequently Asked Questions
What FLIR cameras are supported?
Thermlapse supports the FLIR ONE Classic (Lightning connector), FLIR ONE Edge, and FLIR ONE Edge Pro. Wired cameras (Lightning/USB-C) connect automatically when plugged in. Wireless cameras (Edge/Edge Pro) connect via Bluetooth and Wi-Fi.
Why does the app need Bluetooth and camera access?
Bluetooth is used to discover and connect to wireless FLIR ONE Edge cameras. Camera access is required because the FLIR thermal camera is accessed through the device camera framework. Photo library access is needed to save your captured time-lapse images and exported videos to organized albums. The app does not access your existing personal photos.
Where are my images saved?
All images are saved directly to your device's Photos app in custom albums (e.g., "FLIR_Timelapse_2024-03-15_10-30-00"). Radiometric images preserve full temperature data and can be analyzed later with FLIR Tools or other thermal analysis software. No data is uploaded to the cloud.
What is the difference between Radiometric and Rendered save formats?
Radiometric saves preserve the full temperature data for every pixel, allowing you to re-analyze images later with different palettes and fusion modes. Rendered saves capture only the visual pixels as displayed — smaller file size but no temperature data. Use Radiometric for professional work, Rendered for quick documentation.
What is the minimum capture interval?
The minimum interval is 0.15 seconds, based on the FLIR camera's frame rate of approximately 6.7 FPS. For most practical applications, intervals of 1 second or longer are recommended. You can set intervals in seconds, minutes, or hours.
Can I export my time-lapse as a video?
Yes. Go to the hamburger menu, then Image / Video Capture, then Export Video. Select an album, choose your desired frame rate (1-30 FPS), and the app will compile your image sequence into an MP4 video saved to your Photos library.
What devices and OS versions are supported?
iOS: iPhone and iPad running iOS 15.0 or later. Requires a physical device — the app cannot run in the iOS Simulator.
Android: Devices running Android 13 (API 33) or later with USB-C or Bluetooth connectivity for FLIR cameras.
Android: Devices running Android 13 (API 33) or later with USB-C or Bluetooth connectivity for FLIR cameras.
The camera disconnects during recording. What should I do?
The app automatically attempts to reconnect up to 5 times if the camera disconnects during a time-lapse session. Ensure the camera is securely attached (for wired models) or within Bluetooth/Wi-Fi range (for wireless models). For long sessions, keep wireless cameras charged and consider using a cooling stand to prevent thermal throttling.
