Frequently Asked Questions

What SD cards are compatible with Arlo cameras?
Arlo supports microSD cards up to 128GB with Class 10 or UHS-I speed rating. Cards larger than 128GB may not work. Recommended brands include SanDisk, Samsung, and Kingston.
Will Error 3 stop my Arlo camera from recording?
Yes, Error 3 disables local recording to the SD card. However, cloud recording (if subscribed) and live streaming still work.
How do I check the SD card status in the Arlo app?
Open the Arlo app, go to Settings > My Devices > select your base station. Under Local Storage, you'll see the SD card status and available space.
Can I use a new SD card without formatting?
Most new SD cards come pre-formatted and should work, but reformatting in FAT32 or exFAT ensures compatibility with Arlo.
Why does my Arlo base station keep showing Error 3?
Recurring Error 3 suggests a defective SD card or a faulty SD card slot. Try a different card first; if the error continues, the slot may need repair.
