Quick Answer: A security camera’s data usage depends almost entirely on resolution and recording mode, not the brand. A 1080p camera recording continuously uses roughly 60–120 GB a month (2–4 GB a day), while the same camera set to motion-triggered recording drops to about 10–60 GB a month, according to bandwidth breakdowns from Pro-Vigil and SafetyLegacy. A 4K camera recording continuously can climb to 300–500 GB a month. Cellular (4G LTE) cameras use far less — Reolink’s own official support documentation puts most of its 4G camera lineup at just 1–2 GB a month in typical motion-triggered use, because cellular cameras are engineered around data conservation from the start.
Most buying guides on this site (this one included) talk about resolution, night vision, and AI detection — features you can see in the footage. Data usage is the number you only notice after install, when a home internet data cap gets hit or a cellular data plan runs out mid-month. It is worth checking before you buy, not after.
Data usage by resolution and recording mode
The two biggest levers are resolution (how much data each frame holds) and recording mode (how much footage actually gets uploaded). Multiplying them together explains most of the range you’ll see quoted across different sources.
| Setup | Typical usage | Notes |
|---|---|---|
| 1080p, continuous (24/7) recording | ~60–120 GB/month | 2–4 GB/day per camera, per Pro-Vigil/SafetyLegacy bandwidth data |
| 1080p, motion-triggered only | ~10–60 GB/month | Wide range depends on how much motion the camera actually sees |
| 4K, continuous recording | ~300–500 GB/month | Roughly 4–5x a 1080p camera's footprint at the same recording mode |
| 4G LTE / cellular, motion-triggered | ~1–2 GB/month | Official Reolink support figures for its Go/Duo camera lineup |
| Any camera, local (SD/NVR) recording only | ~0 GB internet data | Video never leaves the local network — see the storage section below |
Wi-Fi cameras also have an upload-speed ceiling worth knowing: most consumer models cap out around 4 Mbps when streaming or uploading to the cloud, according to Deep Sentinel’s bandwidth documentation. That number matters if you’re running several cameras on a single upload connection — four cameras uploading near-simultaneously can briefly saturate a modest home upload speed even if your monthly data cap has plenty of room left.
Reolink Argus 4 Pro
- Records to a local microSD card by default — that footage uses zero internet data, per Reolink's own support documentation, and only clips you actively pull up remotely count against your plan.
- Free on-device AI person/vehicle detection means motion-only recording stays accurate without a paid subscription tier just to filter out false triggers that would otherwise inflate your upload count.

Local storage skips internet data almost entirely
The single biggest lever for cutting a camera’s data footprint isn’t resolution — it’s where the video is stored. Reolink’s own support documentation is explicit on this point: recording to a local microSD card or NVR does not consume internet data, because the footage never has to leave the local network to be saved. Internet data usage only kicks in for clips actually uploaded to the cloud or streamed remotely in the app.
That means a camera that records everything locally and is only checked occasionally over Wi-Fi — as opposed to a fully cloud-backed setup that uploads every motion event as insurance against a stolen or destroyed camera — can use a small fraction of the data a cloud-first camera does, even with identical resolution and motion sensitivity. Our cloud vs. local storage guide covers the tradeoff in more depth (local storage has its own risk: it disappears with the camera).
Cellular cameras: built for low data from the start
Wi-Fi cameras are designed around effectively unlimited home broadband, so keeping data usage low is an afterthought. Cellular cameras are the opposite — every megabyte costs real money on a SIM data plan, so manufacturers engineer them to sip data. Reolink’s official support guidance puts most of its 4G LTE camera lineup (the Go and Duo series) at 1–2 GB a month in normal, motion-triggered use, with higher-resolution dual-lens models like the Duo 2 LTE (6MP) reaching closer to 5 GB. That lines up with what we’ve verified for cellular cameras generally in our best cellular security camera guide: often well under a few gigabytes a month for a typical home or cabin.

- Motion-zone and sensitivity controls let you narrow exactly what triggers an upload, which is the single biggest data-usage lever on a Wi-Fi camera without switching to local-only recording.
- At this price point, running two or three units on motion-only mode still typically stays well under the 1080p continuous-recording range shown in the table above.
Will your cameras trip your home internet’s data cap?
Most U.S. cable and fixed-wireless internet plans that cap data set the limit around 1–1.2 TB a month. A single 1080p camera recording continuously (60–120 GB/month) is a small slice of that on its own — but a typical multi-camera home system changes the math fast. Four cameras all recording continuously at 1080p could approach 250–480 GB a month combined, and mixing in a 4K camera or two pushes that total considerably higher, on top of whatever streaming, gaming, and video-call traffic the rest of the household already generates.
Three changes cut usage the most, in order of impact: switch every camera from continuous to motion-triggered recording (often a 2–5x reduction on its own), lower resolution from 4K to 1080p where 4K detail isn’t actually needed, and record to local storage instead of the cloud where the camera supports it. Our security camera motion zones guide covers how to narrow motion detection further so it only fires on genuine activity, which trims data use without losing meaningful coverage.
The bottom line
Recording mode and resolution — not brand — are what actually determine a security camera’s data usage. Expect roughly 60–120 GB a month per camera for continuous 1080p recording, 10–60 GB for motion-only, and 300–500 GB for continuous 4K; cellular cameras built for data conservation can run as low as 1–2 GB a month. If a data cap or a cellular plan is a real constraint, the fix isn’t necessarily a different camera — it’s motion-only recording, a resolution you’ll actually use, and local storage where it’s available.
