A local recorder provides control, internal bandwidth and operation without internet. Cloud supports remote access and an off-site copy but depends on connectivity and contract. Hybrid storage often combines local recording with a secure copy of critical events.
Key points
- Calculate storage by scene.
- Plan for internet and recorder failure.
- Encrypt data and protect accounts.
- Test search, export and recovery.

Start with evidence needs
Define which events must be found, by whom and how quickly.
Resolution, frame rate, compression, movement and lighting determine volume.

Local NVR
An NVR records over the local network and may continue without internet.
Place it indoors, secured and ventilated, with suitable backup power.
- Local traffic
- Internet-independent
- Capacity
- Physical protection
Edge and cloud
Camera storage can bridge a short network interruption.
Cloud provides an off-site copy but requires checks on encryption, location, contract and bandwidth.
| Model | Benefit | Dependency | Check |
|---|---|---|---|
| NVR | Autonomy | On-site unit | UPS and access |
| Camera edge | Short buffer | Media endurance | Health |
| Cloud | Off-site | Internet | Encryption and region |
| Hybrid | Layered resilience | Complexity | Synchronisation |
Hybrid design
Record continuously on-site and send selected events or a second copy to cloud.

- Critical copy
- Sync status
- Failure alerts
Retention and rights
Tie retention to purpose and Belgian rules; Camera Law generally allows no more than one month with defined exceptions.
Restrict viewing, export and deletion to authorised roles.

Cybersecurity
Use unique accounts, MFA, segmentation and updates; avoid direct port exposure.
Document ownership, recovery and data exit at the end of the contract.

- Encryption
- Segmentation
- Updates
- Portability
Operational testing
Search and export footage, play it elsewhere and simulate internet loss.
Check alerts for capacity, offline cameras and failed synchronisation.

FAQ
Does cloud always replace an NVR?
No. Bandwidth, continuity and contract determine the choice.
Can cameras record without internet?
Yes with local storage while local network and power remain available.
How long should video be retained?
Only as justified and permitted; Belgian Camera Law generally sets a one-month maximum, subject to defined exceptions.
Who should own the cloud account?
The customer should control the owner account and named access.
