Local vs Cloud Storage for Security Cameras, Explained
Every security camera has to put its video somewhere: on a memory card in the camera, on a hub or recorder in your home, or on the maker's cloud servers. That choice decides your ongoing cost, what happens if the internet goes down or a camera is stolen, and who can see your footage. This guide explains each option in plain terms, helps you pick the right mix, and suggests a few storage products that work with popular cameras.

The quick answer
- One to three cameras, low cost: record to a microSD card in each camera and skip the subscription.
- Several cameras from one brand: add that brand's hub or base station so footage is stored in one place inside your home.
- Many wired cameras or 24/7 recording: consider a network video recorder (NVR) or NAS, if your cameras support it.
- You worry about theft or fire, or want the simplest app experience: add a cloud plan for your most important cameras, such as the front door.
Your four storage options
1. microSD card in the camera
Most budget and mid-range Wi-Fi cameras have a microSD slot. The camera records events or continuous video to the card and overwrites the oldest footage when it is full. You view recordings through the app.
- Good: no monthly fee, keeps recording if the internet drops, footage stays in your home.
- Watch out for: if someone takes the camera, the footage goes with it; cards can wear out with constant recording; each camera has a maximum card size (for example, 128 GB on the eufy Indoor Cam C220 and 512 GB on many Tapo and Reolink models).
2. Built-in storage
Some cameras have storage built in, such as the 8 GB in the eufy SoloCam S220 and S340. It works like a memory card you cannot remove: convenient, but small and not expandable.
3. A hub or base station
A brand's hub, such as eufy HomeBase or Reolink Home Hub, collects recordings from several cameras on one device in your home, often with larger or expandable storage.
- Good: one place for all footage, more capacity, recordings stay safe if a single camera is taken, and extra features on some systems (eufy's HomeBase S380 adds face recognition).
- Watch out for: hubs work only with compatible cameras from the same brand, and the hub itself should be placed somewhere a burglar is unlikely to find it.
4. NVR or NAS
A network video recorder (NVR) or a network-attached storage (NAS) drive records many cameras around the clock to hard drives. Cameras that support standard protocols such as RTSP or ONVIF, like the Reolink E1 Zoom, can record to a compatible NVR or NAS; the eufy Indoor Cam E220 supports NAS recording via RTSP.
- Good: large capacity for 24/7 recording, often mixes wired and Wi-Fi cameras, no monthly fee.
- Watch out for: more setup, upfront cost and more technical knowledge; many cameras, especially battery models, do not support RTSP.
5. Cloud plans
A cloud subscription uploads clips to the maker's servers. Examples include Tapo Care, Wyze Cam Plus, eufy cloud plans and Reolink Cloud.
- Good: footage survives if a camera or hub is stolen or damaged, easy access from anywhere, and some plans add smart features.
- Watch out for: an ongoing fee per camera or per home, recording depends on your internet upload, and your video is stored by a third party. Read the privacy and encryption details before you subscribe.
Which should you choose?
- Renters and small apartments: an indoor camera with a microSD card is usually enough. See our indoor and pet cameras guide.
- A single front-door or driveway camera: microSD for everyday recording, plus a cloud plan only if theft of the camera is a real concern.
- Battery and solar cameras around the house: a same-brand hub keeps footage in one place and off the cameras themselves. See our solar security cameras guide.
- Several wired cameras with 24/7 recording: an NVR, NAS or a hub that supports continuous recording.
- Not technical and want it to just work: a cloud plan from the camera maker is the simplest, at an ongoing cost.

Samsung PRO Endurance microSD card: for cameras with a card slot
Who it is for
Anyone recording to a microSD card in a security camera, especially with continuous recording, which wears ordinary cards faster.
Key specs from Samsung
- Designed for video monitoring devices such as security cameras, dash cams and body cams.
- 128 GB capacity in the linked listing (model MB-MJ128KA/AM), with an SD adapter.
- Read and write speeds up to 100 MB/s and 40 MB/s.

Keep in mind
Check your camera's maximum supported card size before choosing a capacity, format the card in the camera's app, and check now and then that recordings are still being saved.

Protecting your footage
- Hide the recorder: place hubs and NVRs out of sight, ideally not next to the router in an obvious spot.
- Keep an off-site copy of key cameras: a cloud plan on one or two cameras protects against theft of the local storage.
- Turn on encryption and two-factor authentication: use the strongest options your camera app offers.
- Check recordings monthly: cards and drives can fail silently. Play back a recent clip to confirm recording still works.
- Know the retention: local storage overwrites the oldest clips and cloud plans keep clips for a set number of days, so save important clips promptly.
- Respect privacy: point cameras at your own property and check local rules on recording.

Frequently asked questions
Is local storage safer than cloud storage for security cameras?
Each protects against different risks. Local storage keeps footage in your home, works without internet and has no monthly fee, but a burglar can take the camera, card or hub. Cloud storage keeps a copy off-site, so it survives theft or damage, but it depends on your internet connection and the provider's security and terms. Many people use local recording and add cloud only for the cameras that matter most.
Do security cameras record without internet?
Many do if they record locally. Cameras that save to a microSD card or a local hub can keep recording when the internet is down, although you will not get phone alerts or remote viewing until it returns. Reolink, for example, says its Home Hub can keep recording from connected cameras without an internet connection. Cloud-only cameras cannot save footage while offline.
How long will a microSD card hold security footage?
It depends on resolution, bitrate and whether the camera records continuously or only on events. As one maker example, Reolink says a 512 GB card in its E1 Zoom holds up to about 8 days of continuous recording at the default bitrate. Event-only recording lasts far longer. When the card is full, most cameras overwrite the oldest footage automatically.
What kind of microSD card should I use in a security camera?
Choose a card designed for continuous recording, often labelled high endurance or for video monitoring, in a capacity your camera supports. Check the camera's maximum card size first, since some top out at 128 GB or 256 GB, and format the card in the camera's app before use.
Do I need a hub or NVR?
Not for one or two cameras that record to their own microSD cards. A hub or NVR makes sense when you have several cameras from the same brand and want footage in one place, larger storage, or recordings that are not lost if a camera is stolen. Hubs usually work only with the same brand's cameras.
What does a cloud plan add besides storage?
Depending on the brand, plans can add snapshot or video previews in notifications, longer clip history, smart search or AI detection features. Check what your camera does without a plan before you buy. For example, Wyze says local event clips on its Battery Cam Pro are about 12 seconds without Cam Plus.
