Resolution and bitrate
A 4K camera generally uses more space than a 4 MP camera. The bitrate is set to balance image quality and archive duration.
Systems from 4 to 128 channels
Luminys NVR to record every camera, 24/7.
The NVR centralizes the cameras, stores video on disk and enables search, playback, export and remote access.

The NVR records, searches and protects your video
The number of channels is only one criterion. Bandwidth, decoding, PoE ports, drives and analytics features must also match the project.

Right-sized capacity
Which NVR fits your installation?
4 to 8 channels
Home, small store or office with the main areas to monitor.
16 to 32 channels
Full retail store, building or warehouse with several indoor and outdoor sectors.
64 to 128 channels
Large installation, multi-site network or deployment requiring high capacity.
Wired architecture
Camera → PoE cable → NVR → app.
Each camera communicates with the NVR over the network. On a PoE system, the same cable carries both data and power.
- Local recording independent of camera Wi-Fi
- Internet needed for remote access, not for local recording
- UPS recommended to protect the network and the NVR
- Rack, ventilation and secure location planned in the project
How is storage calculated?
Frames per second
A higher frame rate makes movement smoother, but increases the volume of recorded data.
Activity and compression
H.265 compression and scene activity strongly affect storage. A busy parking lot produces more data than a quiet hallway.
Retention period
We calculate the terabytes needed for 7, 14, 30 days or more and plan a margin before choosing the drives.

The brain of the video surveillance system
The NVR receives the IP camera streams, records them, indexes events and provides access to live view, playback and export.
What needs to be sized
Actual capacity always depends on the chosen model.Number of channelsFrom 4 to 128 cameras depending on the range, with a margin planned for expansion.
BandwidthTotal incoming bitrate must stay below the NVR’s capacity, especially with several 4K streams.
DecodingDetermines how many high-resolution images can be displayed simultaneously on a monitor.
PoEOn equipped models, one network cable carries data and powers the camera.
DrivesSurveillance drives calculated based on bitrate, fps, number of cameras and days to retain.
ModesContinuous, scheduled, motion-based or analytics event recording.
AccessLive view, search, playback, export and remote access based on configured permissions.
ResilienceMultiple drives or RAID on compatible ranges; backup and redundancy defined based on risk.
Compact example: R31-8PA
8 channels, 8 PoE ports, 80 Mbps recording bandwidth, decoding up to 2 channels of 4K or 8 channels of 1080p, and one drive bay up to 10 TB.
Smart search
With compatible cameras, analytics events reduce the time needed to find a person, a vehicle or an intrusion.
The trap to avoid
Choosing only by the number of ports. Bandwidth, decoding, drives and future growth matter just as much.
Our calculation
We provide a retention estimate based on each camera, not a vague promise of a number of days.
4 to 8 channelsHome, small store or office.
16 to 32 channelsRetail store, restaurant, clinic or building.
64 to 128 channelsWarehouse, industrial or multi-site network.
Drive capacity alone does not indicate the number of days. Two installations with the same number of cameras can have very different retention depending on the scene, compression and bitrate.
