I’m getting a little over a month of HD footage on 256GB cards with cams set to record continuously (24/7). When the card is full, the cam overwrites oldest footage with new. I don’t need DVR-like (NAS) storage for my IP cams as I already have that setup with POE cams. If you’d like to see a Wyze NAS solution, please comment on and/or vote for this Wishlist topic: Network Attached Storage (NAS).
