How to manage photo file types and watermarks
Choose which image file types a camera keeps and add a watermark to its photos, from Media Handling.
A feed's Media Handling settings control what happens to each photo the camera takes: which file types are kept, whether a watermark is added, and where photos are forwarded. This guide covers file types and watermarks. Photo forwarding to cloud storage has its own guide.
Before you start
- Media Handling is an administrator task.
- Decide whether you need JPEG, RAW, or both before you start. RAW files are much larger, so keep them only if you need them.
Set which file types are kept
Open the feed and select the Media Handling section. In Photo file type handling, set the file type for each channel:
- Cloud upload — the images sent to Sentinel OS.
- SSD transfer — the images written to the camera's local storage.
For each channel choose JPEG, RAW, JPEG + RAW, or None. Select Edit, make your choices, then Save.
Add a watermark
In the Watermark card, select Edit. Upload your watermark image and choose its position (one of the corners or the centre). A preview shows how it will sit on the photo. Select Save to apply it to new photos.
Done
New photos follow the file-type and watermark settings you chose. Existing photos are not changed.
Good to know
- RAW files are large. Keeping JPEG + RAW uses much more storage and data than JPEG alone. Choose RAW only where you genuinely need it.
- The cloud upload and SSD transfer channels are set independently, so you can keep RAW locally while uploading only JPEG, for example.
- Watermark and file-type changes apply to new photos going forward, not to images the camera has already captured.
- Photo forwarding to Dropbox or Google Drive is set up in the same section. See Forward photos to cloud storage.
Common questions
Will a watermark change my existing images? No. It applies to new photos from the point you save it.
Should I keep RAW? Only if your workflow needs it. RAW files are far larger, which affects storage and upload data. JPEG is enough for most timelapse and monitoring uses.
