Short answer
Local storage keeps footage on an SD card or a recorder in the house: no monthly fee, but it can be stolen or damaged along with the camera. Cloud storage keeps an off-site copy for a subscription and depends on your internet. A recorder with a small cloud backup helps cover both failure modes.

What is the difference between local and cloud camera storage?
Local storage keeps footage on a device at the property, such as an SD card or an NVR or DVR box, while cloud storage uploads it to a remote server. Local storage needs no ongoing service, but a cloud copy can survive if the local device is damaged, stolen, or fails.
The two aren't mutually exclusive at the system level, even when a single camera is set up to use only one. A property can run some cameras on local storage and others on cloud, or record locally by default with select clips pushed to the cloud as a backup. What matters is where the only copy of a given clip lives, since that's the copy that has to survive whatever happens on the property.
Retention works differently too. Local storage typically overwrites itself on a loop once the card or drive fills up, so older footage is gone unless it was saved first. Cloud storage keeps footage for a window set by the plan. In both cases, retention depends on storage capacity, recording settings, and the selected plan, along with camera count and video quality.
Which is more reliable, local or cloud storage?
Local storage records as long as the device keeps working and isn't tampered with, but a stolen or damaged NVR takes the footage with it. Cloud storage keeps a copy off-site but depends on the internet connection to upload. Some cameras continue recording locally during an outage and upload later when supported; others may leave a gap.
Each option fails in a different direction, which is the part homeowners tend to miss until it matters. A local system fails when someone takes the recorder along with whatever else they came for, and a hall closet or basement may not be as hidden a spot as it feels. A cloud-only camera can fail quietly during an internet outage, leaving a gap unless it records locally and uploads later, and a power outage stops any camera without backup power.

How do local and cloud storage compare on cost?
Local storage costs more upfront for the hardware itself — an SD card or a dedicated NVR — but typically no recurring fee once it's installed. Cloud storage can cost less to start since the storage lives on someone else's servers, but it comes with a monthly subscription for as long as the footage needs to stay backed up.
That gap compounds over time in opposite directions. A local setup's cost is mostly fixed at purchase, aside from an eventual card or drive replacement. A cloud subscription keeps billing for as long as the camera stays in service, and canceling it usually means losing the cloud copy and, on some systems, other features tied to the same plan, although remote viewing may still work without it — a tradeoff worth weighing against what professional monitoring already covers for the property.
When does a hybrid setup make more sense?
A hybrid setup records locally as the primary copy and pushes motion-triggered clips to the cloud as a backup, so a stolen NVR does not erase the only copy. It costs more than either option alone, hardware plus a subscription, but it reduces the single point of failure each option carries.
In practice, that usually means reserving the cloud backup for the cameras that matter most — a front door or driveway — while lower-priority cameras record locally only. The full recording stays on-site either way; the cloud copy is there specifically for the moment the local device isn't available to pull footage from.
