Frequently Asked Questions

What SD Card Do I Need for Reolink E1 Pro?
The Reolink E1 Pro takes a microSD card rated Class 10 / U1 or faster. 64GB or 128GB or 256GB covers most owners, and the maximum is 256GB. Buy SanDisk, Lexar, Samsung or Kingston from a reputable seller: counterfeit cards are the most common cause of lost files.
How do I install the SD card in the Reolink E1 Pro?
You need to tilt the camera lens all the way up. The microSD card slot is hidden just below the lens. Gently push the card in until it clicks. You will need to format the card within the Reolink app before it can be used for recording.
Is Class 10 / U1 required for Reolink E1 Pro?
Yes. Class 10 / U1 guarantees 10 MB/s of sustained write, which keeps the Reolink E1 Pro free of dropped frames, clips that stop early, or corrupted files. Faster cards work too.
What size SD card should I get for Reolink E1 Pro?
64GB covers light use; 256GB suits heavy use. The maximum is 256GB.
Can I use older or slower cards with Reolink E1 Pro?
Not below Class 10 / U1. Slower cards cause dropped frames, clips that stop early, or corrupted files. Check the card label for the Class 10 / U1 mark.
Does the brand matter for Reolink E1 Pro?
Yes. SanDisk, Lexar, Samsung and Kingston cards meet their rated speeds. Buy from the brand's store or a major retailer: counterfeit cards sold under those names are common on marketplaces.
What happens if I use the wrong card with Reolink E1 Pro?
A card slower than Class 10 / U1 causes dropped frames, clips that stop early, or corrupted files. A card over the maximum capacity or in the wrong format may not be recognized.
How long will an SD card last in Reolink E1 Pro?
Several years in normal use. Cards usually fail from wear or counterfeit flash, not age. Replace yours at the first write error, corrupted file or "card not recognized" message.
