Get a 128GB SanDisk High Endurance microSD card. Reolink E1 Pro / E1 Zoom / E1 Outdoor Pan-Tilt uses a microSD Card rated Class 10 / U1. Because home security cameras record 24/7, use an 'Endurance' card instead of a non-endurance card. When you first insert it, tap 'Initialize' inside the camera app.
The official maximum supported capacity for Reolink E1 Pro / E1 Zoom / E1 Outdoor Pan-Tilt is 256GB (tested up to 256GB). For the best balance of price and reliability, our recommended sweet-spot size is 128GB.
64GB ≈ 6 days 24/7 (or 2+ months motion clips) • 128GB ≈ 12 days 24/7 • 256GB ≈ 24 days 24/7. Choosing 128GB gives plenty of headroom without overpaying.
Always tap 'Initialize/Format' inside the phone app when inserting a brand-new card. Standard consumer cards (such as SanDisk Ultra) are not built for continuous loop recording and wear out quickly. Crucially, Western Digital's official warranty terms explicitly exclude dashcam and surveillance use on standard consumer cards (only dedicated High Endurance and MAX Endurance models are covered by warranty). 24/7 loop recording wears out non-endurance memory cards within months; High Endurance flash lasts for years (note: older hardware v1 cameras supported up to 128GB).
Setup requirement: Initialized automatically inside the Camera App. Insert the microSD card while the camera is powered down. Once powered on, open the camera's mobile companion app (e.g. Tapo or Eufy app), navigate to Storage Settings, and tap 'Initialize' or 'Format'.
Yes. Unbranded or counterfeit marketplace cards frequently spoof their capacity or fail to sustain Class 10 / U1 write speeds, leading to corrupted recordings or 'Card Error' warnings. Stick to genuine, branded cards from a reputable retailer to ensure full manufacturer warranty coverage.
