How you schedule recording decides two things at once: whether you capture the events that matter, and how many days of footage your drive can hold. Record everything around the clock and you are safe but the drive fills fast; record only on motion and you stretch storage but rely on detection being tuned; mix them by time of day and you get the best of both. This guide compares continuous, motion-triggered, and time-based recording so you can choose a schedule that fits your site and your storage.
Key takeaways
- Continuous recording captures everything but fills the drive fastest.
- Motion recording stretches storage far further but depends on well-tuned detection.
- Time-based scheduling records differently by hour — e.g. continuous at night, motion by day.
- Match the schedule to the location: a till continuous, a quiet corridor on motion.
- More cameras, higher resolution, and longer retention all need a bigger drive.
Continuous recording — when it is right
Continuous recording captures every second, all the time, regardless of whether anything is happening. Its strength is certainty: nothing is ever missed, and there is no reliance on detection settings being right. Its cost is storage — recording empty hours fills a drive far faster than events alone would. Continuous is the right choice for high-risk, high-value points where a gap is unacceptable: a till, a safe, a cash-handling area, or a main entrance in a busy business. For these, the peace of mind is worth the extra drive space.
Motion-triggered recording — the storage saver
Motion recording only writes to the drive when the camera detects movement, skipping the long empty stretches that fill continuous storage. The saving is large — the same drive can hold several times more days of actual events — which makes motion the practical default for most cameras. The trade-off is that it relies entirely on detection being tuned well; a badly set zone or sensitivity either misses events or records constant false triggers. Pair motion recording with a tight detection zone and smart human and vehicle detection, and you get long retention without missing what matters.
Time-based recording — the smart mix
Time-based recording changes the mode by the hour, and it is often the smartest choice of all. You might record continuously overnight when any activity is suspicious, and switch to motion-only during the day when normal comings and goings would otherwise fill the drive with nothing useful. A shop can record continuously during opening hours and on motion after close; a home can do the reverse. This schedule captures everything when it counts and saves storage when it does not, which is exactly the balance most sites actually need.
Match the schedule to the location
The best systems do not use one schedule for every camera; they match each camera to its risk. Put the till, the safe, and the main entrance on continuous, where a missing second is unacceptable. Put quiet corridors, storerooms, and side passages on motion, where events are rare and storage is better spent elsewhere. Use time-based on cameras whose risk changes with the hour, like a shopfront. Deciding this per camera, rather than applying one blanket mode, is what keeps both coverage and storage sensible.
Sizing storage for your schedule
Whatever mix you choose, the drive must match it. Storage need grows with the number of cameras, their resolution, and how many days you want to keep — and your recording mode is the big multiplier in between. A continuous, high-resolution setup can need many times the storage of a motion-based one for the same retention. Decide your retention target first — two weeks suits most homes and shops — then size the drive to your schedule, and add a little headroom so a future camera does not shorten how far back you can look.
Frequently asked questions
Which recording mode uses the least storage?
Motion-triggered recording uses the least, because it skips the empty time that continuous recording captures. On a typical scene, motion can stretch the same drive to several times the days of continuous recording. Time-based sits in between, depending on how many hours you run continuously. If storage is your main constraint, well-tuned motion recording is the most efficient choice.
Is continuous or motion recording better?
Neither is better in general — they suit different spots. Continuous is better where a gap is unacceptable, like a till or a main door. Motion is better where events are rare and you want to save storage, like a quiet corridor. Most good systems use both across different cameras rather than picking one mode for everything.
How many days of footage should I keep?
Two weeks is a sensible target for most homes and shops — long enough to notice and review an incident without needing an oversized drive. Some businesses keep 30 days or more for compliance or insurance reasons. Decide your retention first, then size the drive and choose a recording mode that hits it; the schedule and the drive together determine how far back you can actually look.
Can different cameras use different schedules?
Yes, and they should. A good recorder lets you set the mode per camera and even per time block, so the till records continuously while a back corridor records on motion. Tailoring each camera to its own risk is exactly how you get full coverage where it matters without wasting storage where it does not.
