Continuous vs Event Recording for IP Cameras

Continuous recording prioritizes coverage

Continuous recording reduces dependence on detection accuracy. If an event detector misses the start of an incident, the baseline recording may still contain it. The tradeoff is predictable, sustained storage and write bandwidth across every enabled camera.

Use a lower-bitrate stream when the purpose is situational history rather than fine identification. The recording should still have enough resolution and frame rate to answer the questions you expect to ask later.

Event recording prioritizes attention

Event clips reduce the amount of footage people must review and can preserve higher quality around important moments. Their weakness is the trigger boundary: detection can start late, stop early, or fire too often. Pre-event and post-event buffering help, but they do not make a detector infallible.

Review false positives by type and adjust motion regions, schedules, sensitivity, or object filters instead of disabling all event logic after a noisy day.

Why hybrid recording is often the best default

A hybrid design uses the sub stream for 24/7 coverage and the main stream for event evidence. That separates two goals: retaining broad history at a manageable bitrate and preserving more detail when something happens.

OmniNVR is designed around this split. The timeline can combine continuous segments and event markers so review starts with an alert but can move before or after it without leaving the recording context.

Choose policy by failure cost

• Home awareness: hybrid recording balances context and storage.
• Temporary monitoring: event-only may be sufficient if misses are acceptable.
• Operational evidence: continuous recording is safer when missing a period is costly.
• Privacy-sensitive areas: use schedules, masks, and the minimum necessary retention.

The correct policy is not the one with the most footage. It is the one whose known failure modes match your risk and review workflow.
