How to Choose a Security Camera for True Continuous Recording

A “24/7” label does not guarantee uninterrupted video. Compare recording mode, power, storage compatibility, retention, installation, and cloud dependence before choosing a security camera.

For footage that records the time between motion events, choose a camera explicitly documented to save uninterrupted video—and verify that its power setup and storage support that mode. “24/7” can also describe event clips or interval snapshots, which are not continuous full-rate video.

What counts as continuous recording?

Continuous recording means the camera saves video without interruption during its enabled schedule. Motion-triggered recording saves clips only after an event is detected, so footage between events may be missing. Battery-camera interval capture is different again: it takes snapshots during quiet periods and switches to higher-frame-rate recording when an event occurs.

TP-Link’s support documentation describes continuous recording as footage captured “non-stop” so users can review a chosen timeframe. The same guidance distinguishes it from detection recording, which saves triggered footage rather than a continuous timeline. TP-Link’s continuous-recording guide (updated June 26, 2026) explains the difference and how to enable the feature in the app.

Which camera type fits your needs?

Camera or setup Recording mode to verify Power and storage considerations
Wired camera with local storage Potentially suitable for uninterrupted video, but confirm the exact model supports continuous recording and check its schedule settings. May use mains power or PoE and a camera microSD card, hub, or recorder, depending on the model.
Battery-powered camera Often designed around event clips or interval snapshots rather than continuous full-rate video. Confirm the specific model’s feature set. Continuous video can conflict with battery-oriented operation. Some models offer interval capture, which is not equivalent to continuous video.
Multi-camera system with a recorder Check that the camera and recorder combination supports continuous recording, not just motion schedules. Consider recorder capacity, network cabling, remote access, and whether local recording continues during an internet outage.

These categories are selection guidance, not a verified model-by-model ranking. Editorial roundups identify Reolink, eufy, Lorex, UniFi Protect, and TP-Link VIGI as local-storage options, but that does not establish that every model from those brands records continuously. Compare the manufacturer’s documentation for the precise model, regional version, hardware revision, and power arrangement. TechRadar’s home security camera guide and iTechGuides’ local-storage guide can help build an initial shortlist.

Power determines whether the mode is practical

A camera must stay powered to record continuously. In TP-Link’s Tapo lineup, the documented continuous-video feature excludes battery-powered cameras and doorbells. Battery models may instead offer “24/7 Capture”: interval snapshots during quiet periods, followed by higher-frame-rate event recording. Support depends on the model. TP-Link’s 24/7 Capture guide describes that mode and its limits.

The distinction matters when comparing headline claims. A product page’s “24/7” wording alone does not tell you whether it means uninterrupted video, motion clips available around the clock, or periodic images between events. Look for an explicit description of what is saved and when.

Choose compatible storage and plan retention

Local continuous recording needs compatible storage. TP-Link documents supported Tapo cameras saving continuous recordings to a microSD card or Tapo Hub, with recording enabled in the app. Card capacity and compatibility vary by camera and hardware version; consult the exact model’s documentation and TP-Link’s microSD compatibility guide (updated June 3, 2026).

  • Card type: TP-Link recommends high-endurance, max-endurance, or pro-endurance microSD card families for continuous security-camera writing.
  • Capacity: Do not assume a card size is supported just because it fits. Check the camera’s model and hardware revision.
  • Retention: How long footage remains depends on resolution, frame rate, compression, the number of cameras, and storage capacity. Confirm whether the camera overwrites older recordings when storage fills.
  • Storage location: Establish whether footage is saved to a camera card, hub, NVR/recorder, cloud service, or a combination.

For scale, TP-Link estimates that its battery-camera 24/7 Capture snapshot mode uses about 173 MB per day at a 10-second interval, or about 1,730 MB per day at a one-second interval, when no detection event occurs. These are manufacturer estimates for interval snapshots—not estimates for full-rate continuous video—and should not be used to predict video retention. TP-Link’s guide gives the conditions for those figures.

Check the installation, network, and privacy trade-offs

Before choosing a camera, compare how it connects and where recordings go. Wi-Fi can simplify installation, while Ethernet or PoE requires cabling but can combine network and power for supported equipment. Confirm whether a camera can keep recording locally if the internet connection fails; remote viewing and cloud services may have separate connectivity requirements.

  • Subscriptions: Check which functions require a plan, including cloud history, alerts, or advanced detection. Local recording does not by itself establish that every feature works without a subscription.
  • Privacy: Review the manufacturer’s data-handling disclosures and decide whether local-only storage or cloud access better suits your household.
  • Setup: Confirm the exact regional model, hardware revision, power source, app setting, and storage compatibility before purchase.

TP-Link’s UK product page for the C501GW advertises “24/7 Secure Local Recording” to microSD up to 512 GB or Tapo Care cloud storage, and describes DC-powered or PoE installation. That is a regional product-page claim, not a substitute for confirming that the particular model and configuration provide the uninterrupted video mode defined here. See the UK C501GW product details.

A practical checklist before buying

  1. Define the footage you need. If you need to review what happened between motion events, require explicit continuous-video support rather than event clips or interval snapshots.
  2. Verify the exact product. Check the regional model and hardware revision in manufacturer documentation; confirm the feature works with your intended power source.
  3. Identify storage and settings. Determine whether the camera writes to microSD, a hub, an NVR, or cloud, and find the app or recorder setting that enables the desired schedule.
  4. Check compatibility and retention. Confirm the supported card or recorder capacity and estimate retention using the device’s video settings and number of cameras.
  5. Assess network and ongoing requirements. Check cabling, remote access, offline behavior, subscription gates, and privacy disclosures.

A camera may not include a storage card. If buying one separately, choose a high-endurance card that the exact model supports; do not infer compatibility from capacity alone.
