The sufficiency of 1 TB for CCTV largely depends on several factors:

1. Number of Cameras: A single camera might be adequately served by 1 TB, especially if it's recording at a moderate resolution and frame rate. However, multiple cameras will require more storage space.

2. Resolution and Frame Rate: Higher resolution footage (like 4K) or higher frame rates will consume more storage. If your cameras are recording at higher resolutions or faster frame rates, 1 TB might not be enough.

3. Retention Period: How long do you intend to store the footage? The longer the retention period, the more storage space you'll need.

4. Compression and Settings: Some CCTV systems offer compression settings that affect storage needs. Adjusting these settings might allow for more footage to be stored in 1 TB.

Considering these factors, 1 TB might be sufficient for a single camera recording at a standard resolution (1080p) and moderate frame rate if the footage is not retained for an extended period. However, for multiple cameras or higher-quality recordings, more storage will likely be necessary. It's always a good idea to calculate based on your specific cameras' settings and expected storage requirements to ensure adequate space for your needs.
